Passenger Satisfaction of Singapore Airlines-Samples for Students

Question: Investigate satisfaction of passengers using Singapore airlines about their personal experience with the journey and other aspects. Answer: Rationale for the research design The research design includes the research philosophy, research approach, research design, method, and investigation. Research philosophy includes positivism, realism, and interpretivism. This current study will take positivism philosophy. Positivism philosophy focuses on the collection of scientific data. Factual knowledge is the main part of positivism philosophy (Taylor, Bogdan DeVault, 2015). By using this philosophy the researcher will be able to gain data through observation and measurement. However, during the use of positivism philosophy, there are some limitations while collecting data. By using positivism philosophy the researcher will be able to carry out a quantifiable observation and statistical analysis. On the other hand, this current study is based on the deductive approach. Creation of the hypothesis is the major aspect of deductive approach (Choy, 2014). Deductive approach is useful to evaluate the relationship between the variables and the concepts (Mackey Gass, 2015). Therefore, the deductive approach helps the researcher to generalize the current research findings. In this current research study, the descriptive design will be used as the research design. Descriptive research design includes a set of research objectives and research questions. Therefore, the research problem is clearly defined by the descriptive design. This current study deals with the passengers satisfaction in Singapore Airline, which can be analyzed by using this research design. In this current study quantitative process will be used to collect primary data. To conduct the quantitative process market survey will be carried out in this research method. Discussion of specific research methodology This current study includes both primary and secondary research methods. Primary method includes quantitative process. To conduct the quantitative process a market survey will be taken to gather feedback from the customers of Singapore Airline. This survey will be helpful to measure the satisfaction level of the passengers in Singapore Airline, which is the primary question of this research study. Survey will help the researcher to identify the areas that are required to improve to enhance the customer satisfaction level in this organization. Hence, survey will enable the researcher to meet the primary and secondary questions of this current study. Survey is an effective method to get real-time data during the investigation (Lewis, 2015). By analyzing the customer feedbacks the Singapore Airline will be able to make necessary changes to improve the level of customer satisfaction. This also meets the research objective as from the current feedbacks this organization will be able to fi nd out the way to improve the customer satisfaction in their organization. Questionnaires will be provided via online to gather the feedback from the customers of Singapore Airline. Secondary research is also important besides the primary research as it provides authentic evidence regarding an issue to the researcher (Flick, 2015). In this study, secondary research will be conducted during the literature review. Census report, academic journals, authentic websites, and books will be used to collect data on customer satisfaction level in Singapore Airport. Hence, both the secondary sources and primary sources are valuable to meet the research objectives and questions Rationale for the research methodology Primary method will be used in this current study, which is helpful to gain realistic data. However, during the collection of primary data survey questionnaires will be provided to the candidates to understand their perspectives. However, often the candidates provide diplomatic answers, which can hamper the data collection process. The main reason of primary research is to obtain real-time data as real-time data gives the current status of an organization in the market (Silverman, 2016). For Singapore Airline survey will be helpful to understand the current satisfaction level of the passengers as well as their concerns regarding the service. On the other hand, the main reason of the secondary data collection is to review the previous status of the Singapore airline industry and current views regarding the service. This information will be collected through the authentic websites and the journals. By using the marginal probability in payoff matrix information will be collected from th e census report. Discussion of the key consideration of the research methodology After conducting the entire methodology the research will be concerned about the process of publication. One of the major considerations is the protection of data that needs to follow during the primary research (Panneerselvam, 2014). However, the researcher has to keep confidentiality while gathering data through survey. For this purpose Data Protection Act needs to be followed. Therefore, the researcher has no right to force the candidates to involve in the survey. The personal data of the candidates should be protected. No personal questions can be generated during the survey. These elements should be considered during the conduction of primary research methodology. On the other hand, in the context of secondary research the data cannot be manipulated and proper citation should be done properly. The data needs to represent in its original process. Discussion of the information that needs to collect by the market research agencies This current research is based on the investigation of passenger satisfaction level in Singapore Airline. Hence, the market research agency needs to collect the feedback from the passengers regarding the current service process of this organization. Therefore, the major loopholes of the current system will be collected to identify the gap of the service. The disadvantages of the current system in Singapore Airline needs to evaluated to take proper action against these issues. The market agency will collect the information regarding the pricing strategy, quality and boundaries of the Singapore Airline as these are the major concerns of the passengers. On the other hand, the current expectation of the customers from the Singapore Airline will be identified by this agency. The primary data will be represented and analyzed by using graphs, charts, and table. The secondary data will be represented by using proper citation. Critical evaluation will be made during the analysis of the second ary data in this current research study. Finally, it has been found that for the current research both primary and secondary sources will be helpful to analyze the current issues and to develop suitable recommendations to mitigate such issues.

Neptunium essays

Neptunium essays What the heck is Neptunium? That is the question that first popped into my mind when I saw this name. I mean, Ive heard of neptune, its obviously a celestial body in the heavens that we petty earthlings refer to as a planet, or planeta for my spanish speaking friends. But neptunium, I mean, come on, cant you at least think of a more creative name. Despite the lack of creativity on the name, neptunium is actually quite a hoot. Its an interesting element and its quite obscure as well. And without further adue, here are some facts about this zany element. Np. Whats Np you ask, well its the chemical symbol. Its atomic number is 93. Atomic weight 237 correctly describes this thing. Neptunium has a melting point of 644 C. Its specific gravity is 20.25. Its boiling point is 3902 C. It has 15 isotopes. Wow, I reckon thats a lot of isotopes. The discover is McMillan and Abelson in the year 1940. As I recall, thats the jist of the obscure facts section of the supposed essay. Neptunium has some pretty boring info, but here it is anyway. Neptunium is a ductile, silvery radioactive metal. It is a member of the actinide series in group IIIb of the periodic table. Neptunium has three distinct forms. Neptunium forms numerous chemical compounds. The element was discovered in 1940 by Edwin M. McMillan and Philip H. Abelson, who produced neptunium-239 (with a half-life of 2.3 days if I correctly recall) by bombarding uranium with neutrons from a cyclotron at the Univ. of California at Berkeley. Neptunium, the first transuranium element (thats a big word), was named for the planet Neptune, which is beyond Uranus in the solar system. Neptunium is found in very small quantities in nature in association with uranium ores. There are 20 known isotopes of neptunium. Neptunium-237, the most stable, has a half-life of 2.14 million years and is used in neutron-detection equipment. And thats all fo ...

Change Management of an Organization Essay Example | Topics and Well Written Essays - 2500 words

Change Management of an Organization - Essay Example So the above mentioned lines are indicating one more interesting technique to reach organizational goals, that is changing the people's attitude, their way of working, and behavior towards work so that organization can reach its objectives through change which is probably the only way for it to reach its goals as modernization automatically changes the surroundings, behaviors of buyers, the variety of competition and so on. The business doesn't get changed itself, nor does it require it self to change with out any need as the profitability (growth) or survival is the core objective of any business, but when it comes to change, only external factors make an organization or business change primarily, afterwards the firm changes it self may be in internal manners. The External change drivers that can be seen commonly in this modern world or from the time the changing took place include Mega Environment1, it further includes Technological Element, in which the modern technology that is used outside the firm, perhaps around the world and by the competitors tends to change the organization, the failure to use such technology can result in loss of values, customers, and most importantly long-term profits. The next external change is brought by Economic Element, of course the change in the country's wealth distribution, it's financial debt and the inflation can create unbalance in an organization or any business, such as the decrease in the price of a certain commodity or product can have some negative impact on the firms profitability, specially if the country in which the organization is operated is a socialist economy in which the government owns a lot than the individuals. The next one is Legal-Political Element, these are somewhat the governm ental forces that affect the business or organization from outside, such as passing a new taxation rule, or a new policy which implementation can also make an organization to change its norms and policies, in such cases the organizations are forced to follow such rules, or they can be penalized. The Socio-cultural Elements is another external change driver, here the attitudes, norms, traditions, behaviors etc. that the people of the country in which the organization is operated follow, a good example is that if a food business is being operated and Muslims somehow enter into that area demanding the cautionary meat, the organization would have to change and would have to start making the demanded meat. The last of Mega environments is International Element, these are general norms followed by the organizations being operated around the globe, for instance, the McDonald's in every country has to follow somewhat the same standards that parent company is following, other wise it can be penalized. Now lets discuss an other sort of External Change driver, it is called Task Environment2, it includes Customer and Clients, of course they are the only ones because of whom change is adopted, the customers

M.bovis Genetic Diversity

M.bovis Genetic Diversity Mycoplasmabovis pneumonia is an epidemic worldwide. To understand M.bovis genetic diversity would help develop novel measures to control this disease. Therefore this study was aimed to determine genotype distribution of Chinese strains and the potential global evolution. Firstly three available methods including two M. bovis multilocus sequence typing (MLST) schemes MLST-1 and MLST-2 and pulsed field gel electrophoresis (PFGE) were comparatively used for 44 Chinese strains and M. bovis type strain PG45 originated fromUSA. The results showed a high genetic homogeneity of Chinese isolates. By MLST-1, 43 of 44 (97.7%) Chinese isolate being ST-10, while 1 of 44 ST-34. The MLST-2 scheme clustered 44 Chinese isolates into two sequence types, ST-10 43 of 44 (97.7%) and 1 of 44 ST-32. PFGE clustered 42 of 44 (95.5%) into PT-I. The discrimination index was highest for PFGE (D = 0.160), while both MLST schemes have similar discrimination power (D = 0.110). The agreement rate among three typing methods is 95.4%à ¯Ã‚ ¼Ã‹â€ 95% CIà ¯Ã‚ ¼Ã… ¡84.2%, 99.4%à ¯Ã‚ ¼Ã¢â‚¬ °. The type strain PG45 gave a unique type by all three methods. Additionally, MLST-2 scheme was used to analyze 8 Australia and 8 Israeli isolates. The results showed 8 Israeli strains represent three STs with ST-10 as the most dominant type comprising 50% of the strains, ST-20 (n=2) and ST-28 (n=2). The 8 Australian isolates showed two sequence types ST-10 (n=7) and another sequence type ST-41 (n=1) identified firstly here. The assay of evolutionary relationship by geoBURST Minimum spanning tree (MST) of 60 isolates typed in this study and 207 isolates of 11 countries from the MLST-2 database. It was revealed that similar dominant clone (ST-10 in CC 3) exists in China, Israel, Australia and United States. This may be related to global livestock movements. In conclusion, we firstly demonstrated the remarkable clonality of M. bovis in China and the dominant ST-10 might originate from a common global source. Key words: Mycoplasma bovis; molecular epidemiology; multilocus sequence typing (MLST); pulsed field gel electrophoresis (PFGE); cattle; evolution. Mycoplasma bovis (M.bovis) is the main causative pathogen of bovine mycoplasmosis worldwide such as in North America, Europe (Nicholas and Ayling, 2003), China (Shi et al., 2008), Australia (Morton et al., 2014) and Israel (Lysnyansky et al., 2016). It results in substantial economic losses to producers by causing M.bovispneumonia and mastitis in beef and dairy cattle. M. bovis was first isolated in 1961 in USA from cattle mastitis milk (Hale et al 1962) and has long been considered a player in bovine respiratory diseases (BRD) since 1976 (Thomas et al., 1986). It then appears to have spread via animal movements to, amongst many countries (Nicholas 2002). Today, infection occurs in most European countries and throughout the world. It was estimated that the economic loss caused by M.bovisin United States was up to $108 million per year. In Europe, M.bovis pneumonia constitutes about 30% of calf respiratory diseases (Nicolas and Ayling, 2003; Maunsell et al., 2011). As the prevalence o f M. bovis associated diseases varies widely across the world, there are important trade implications and a pressing need to monitor cattle for M. bovis. However, to date, there are large gaps in our understanding evolutionary relationships of this pathogen isolates between different countries and globally. In China the first M. bovis mastitis was described in 1983 (Chen et al., 1983) and first M. bovis pneumonia in 2008. Since then reports of M. bovis pneumonia and mastitis outbreaks have been frequently described (Shi et al., 2008; Peng et al., 2011). M. bovis pneumonia is characterized by severe respiratory distress, high fever and at postmortem lung lesions including carnification, extensive caseo-necrotic or suppurative foci in the lungs. M.bovis pneumonia caused over 80% morbidity and between 10% to 60% mortality in calves and stockers newly introduced into beef feedlots (Shi et al., 2008). A major contributing factor to this disease is the stress caused by the long distance transportation of calves and stockers between the feedlots and farms (Shi et al., 2008). The disease is difficult to control with chemotherapy, and vaccination would be an ideal alternative approach. An insight of the genetic diversity and population structure of M. bovis would assist in the development of novel vaccines, as well as gaining an insight into evolutionary trends. A variety of molecular typing methods have been used for epidemiological characterization of M. bovis strains including random amplified polymorphic DNA (RAPD) analysis (Butler et al., 2001), amplified fragment length polymorphism (AFLP) analysis (Kusiluka et al., 2000; Soehnlen et al., 2012), pulsed field gel electrophoresis (PFGE) (Pinho et al., 2012; Arcangioli et al., 2012), insertion sequence (IS) typing (Miles et al., 2005; Aebi et al., 2012) and multilocus variable number tandem repeats (VNTR) analysis (Pinho et al., 2012; Spergser et al., 2013). In addition, three multi-locus sequence typing (MLST) schemes were recently developed to study population structure, evolution and spread of this pathogen (Manso-Silvan et al., 2012;Register et al., 2015; Rosales et al., 2015). The MLST scheme developed by Manso-Silvan et al. (2012) is based on four housekeeping genes fusA, gyrB, lepAand rpoB and showed a discrimination index of 0.833, while improved MLST scheme have been developed by Rosales et al.2015) here after referred as MLST-1 scheme; and by Register et al. (2015) here after referred as MLST-2 scheme. Both schemes use seven housekeeping genes but they only have one gene in common and therefore theire discrimination power higher than the Manso-Silvan scheme. In the present study, it was aimed to firstly evaluate the three methods MLST-1 and MLST-2 schemes and conventional PFGE by comparing the results in typing 44 Chinese M.bovis isolates, secondly assess the genetic diversity and population structure of M. bovis strains isolated in period of 2007 2014 by using the type strain PG45 as the control., and thirdly explore the evolutionary relationship of Chinese M.bovis isolates with globally diverse isolates. Material and Methods Mycoplasma bovis isolates M. bovis Chinese isolates (n=44) were obtained during 2008 to 2014 from nine Chinese provinces: Hubei (n=25), Anhui (n=1), Fujian (n=2), Hunan (n=1), Jiangxi (n=3), Henan (n=8), Inner Mongolia (n=1), Guangzhou (n= 2) and Shandong (n=1). These M. bovis isolates were mostly from lungs in cases of pneumonia (n=41); together with other sources such as milk with mastitis (n=2); throat swab in case of pneumonia (n=1) and fluid of joint with arthritis (n=1). The M. bovis type strain PG45 was purchased from American Type Culture Collection (ATCC 25523) and also used in this study. DNA samples from 8 Israeli M. bovis isolates were kindly offered by Prof. Dr. Inna Lysnyansky from Kimron Veterinary Institute, Israel, collected during 2013-2014 from pneumonia (n=6), stillbirth (n=1) and arthritis (n =1) in seven regions namely Gilboa (n=1), Beer Tuvia (n=3), Hevel Eilot (n=1), Eshkol (n=1), Jerusalem (n=1), Mateh Yehuda (n=1) and EmekYizrael (n=1). In addition, eight whole genome sequences of Australian M.bovis isolates were retrieved from GenBank representing mastitis, (n=4), lungs (n=1), nose swab (n=1), joint fluid (n=1) and semen culture (n=1) in five regions namely New south Wales (n=2), Queensland (n=1), Tasmania (n=3), South Australia (n=1) and Victoria (n=1) with accession no. SAMN05444185, SAMN05444199, SAMN05444228, SAMN05444239, SAMN05444243, SAMN05444247, SAMN05444250, SAMN05444261) included in this study (Table 1). Growth conditions, species identification and DNA extraction M.bovis isolates were confirmed by species-specific PCR as previously described (Subramaniam et al., 1998). The M.bovis samples were grown in PPLO broth (Difco) supplemented with 0.5% (w/v) sodium pyruvate (Biosharp, China), 0.09% (w/v) yeast extract (BD Biosciences, San Jose, CA, USA)à ¯Ã‚ ¼Ã…’0.004% (w/v) phenol red, 1% (v/v) 10- minimum essential medium (MEM) (Sigma-Aldrich, Saint Louis, MO, USA), 20% (v/v) Hyclone donor horse serum (Invitrogen, Carlsbad, CA, USA) and penicillin G 80,000 IU/100 mL and the final pH was adjusted to 7.6(Khan et al., 2016). DNA from each isolate was extracted using the genomic DNA extraction kit (Tiangen, Beijing, China). Multilocus sequence typing (MLST) MLST-1 scheme is based on a partial sequencing of dnaA, metS, recA, tufA, atpA, rpoD and tkt genes (Rosales et al., 2015); For MLST-1 scheme, 44 Chinese isolates and American type strain PG45. The PCR amplification conditions for MLST-1 were used as previously described (Rosales et al., 2015); after amplification, PCR products were further purified and sequenced using PCR Products Extraction Kit (Magnetic Beads) (Enriching Biotechnology, LTD, Wuhan, China) and sequenced. Sequencing reactions were performed by the commercial company (Tianyi Hui Yuan Biological Technology Pvt. Ltd. Wuhan, China).The quality of chromatograms was checked visually and sequence data were assembled and edited using SeqMan software (DNASTAR Inc., Wisconsin, USA). The assembled MLST-1 sequences were compared using non-redundant database (NRDB) comparison tool available in http://pubmlst.org/analysis/ with our previously analyzed 10 strains used as a control to assign allele and Sequence type number (Rosales e t al., 2015). MLST-2 scheme is based on a partial sequencing of adh-1, gltX, gpsA, gyrB, pta-2, tdk and tkt (Register et al., 2015). For MLST-2 scheme, the 44 Chinese strain and PG45 were subjected to PCR, and PCR products were sequenced as above mentioned method. The assembled sequences of all isolates were uploaded to http://pubmlst.org/mbovis/database to identify allele numbers and sequence types (STs). In addition, for the evolutionary assay, 8 Israel strains were typed with the method as described above. Meanwhile, 8 Australian isolates whole genome were annotated using prokka 1.11rapid prokaryotic genome annotation software (Seemann; 2014) at http://www.vicbioinformatics.com. Each locus sequence was extracted from the annotated genome. Pulsed Field Gel Electrophoresis (PFGE) analysis PFGE of 44 Chinese M.bovis field strains and type strain PG45 was performed as previously described (McAuliffe et al., 2004, Arcangioli et al., 2012) with some modifications for agarose block preparation. Briefly, macro-restriction analysis was performed with the restriction enzyme SmaI as follows: Each M.bovis isolate 15 ml culture aliquot was centrifuged at 15000 à ¯Ã¢â‚¬Å¡Ã‚ ´g for 20 min at 40C, the pellet was washed three times with Tris-EDTA buffer and resuspended in 400 à ¯Ã‚ Ã‚ ­l of cold Tris-EDTA buffer (pH 8.0). Agarose plugs were prepared from a 1:1 mixture of the above cell suspension and 2% low-melting-boiling agarose (Bio-Rad). They were then incubated in a lysis buffer containing 10mM Tris-HCl, 1 mM EDTA, 1% lauroyl sarcosine, 1mg of proteinase K per ml for 48 h at 560C. These plugs were washed for 6h with several changes of Tris-EDTA buffer at 40C. The plugs were then cut aseptically into 2 mm sections and equilibrated in 120 à ¯Ã‚ Ã‚ ­l restriction buffer (Prom ega) for 30 min at 40C. Subsequently, plugs were digested with 30U of SmaI (Promega, Shanghai, China) at 240C for 4 h. After digestion loaded in 1% pulsed-field-certified agarose gel (Bio-Rad), and run in a CHEF-DRIII system (Bio-Rad) at 6V/cm, in 0.5à ¯Ã¢â‚¬Å¡Ã‚ ´ TBE buffer at 140C, at 6V/cm with angle of 1200. The initial pulse time was 5s, with a final pulse time of 40s with a running time of 24 h. The lambda DNA ladder PFGE marker (Bio-Rad) was used as a reference. PFGE fragments in the gel were stained with ethidium bromide (EB) (1mg/ml) for 20 min, and destained in distilled water for 1.5 h and visualized under UV transilluminator. Pulsotypes (PT) were assigned numbers consecutively based on differences of more than one band in PFGE patterns upon visual inspection. The banding patterns were analyzed using Dice coefficients with 1% band position tolerance. The clustering of patterns was performed using unweighted pair group matching algorithm (UPGMA) as previously described ( Arcangioliet al., 2012; Timsit et al., 2012). Allelic sequence variance analysis The Sequence Type Analysis and Recombinational Test Version 2 (START2) (Jolley et al., 2001) were used to analyze polymorphic sites, construct UPGM dendrograms and calculate non-synonymous to synonymous ratios (dN/dS). Genetic diversity (H) of each locus and Index of Association (IA) were calculated by using LIAN 3.5 (Haubold and Hudson, 2000) hosted on http://guanine.evolbio.mpg.de/cgi-bin/lian/lian.cgi.pl/query. Global evolution and minimum spanning tree (MST) analysis The evolutionary relationship between isolates and M.bovis population structure was determined using PHYLOViZ (Fransciso et al., 2012) and evaluated by minimum spanning tree (MST) created using eBURST (geoBURST) algorithm (Francisco et al., 2009). MST for MLST-2 was performed for 257 isolates from 11 countries including 60 strains (44 China, 8 Israeli and 8 Australia isolates)   typed in this study and 207 isolates   retrieved January, 2017 (Supplementary Table 3) from the M.bovis MLST-2 database www.pubmlst.org/mbovis. Statistical analysis The discriminatory ability of both MLST methods and PFGE was calculated using Simpsons index of diversity as previously described (Hunter and Gaston, 1998). Congruence between both typing techniques was measured using the adjusted Rand Coefficient and Wallace Coefficient (Severiano et al., 2011). All statistical analyses were performed using the freely available online tool (http://darwin.phyloviz.net/ComparingPartitions/) Results The comparison of M.bovis typing with three methods MLST-1 analysis A total of 44, out of 10 were previously typed (Rosales et al., 2015) were also used for control and typed by MLST-1. The mean GC contents of seven gene fragments ranged from 29.15% (dnaA) to 37.23% (tufA) while it was 37.4 % in the whole M. bovis HB0801 genome (Qi et al., 2012). For each of seven loci, allelic variation was analyzed including polymorphic sites, guanine-cytosine(GC) content, synonymous and non-synonymousratios (dN/dS)(Table 2).The number of polymorphic sites per locus ranged from 4 (6.2%) in recA to 19 (29.6 %) in dnaA, and a total of 64 polymorphic sites for all seven genes were identified. The number of alleles observed ranged from 2 (metS, recA, tufA, atpA, and tkt) to 3 (dnaA and rpoD). The genetic diversity (H) for each locus was 0.0879 for dnaA and 0.0444 for metS, recA, tufa atpA and tkt. The dN and dS substitutions ranged from 0.0000 to 0.0623. In summary, all 44 Chinese M.bovis isolates typed by MLST-1 were divided into two STs namely ST-10 and ST-34 (Table 1).The ST-10 (with allelic profile of 2,6,2,2,2,5,3) was most numerically dominant, comprising 97.7%à ¯Ã‚ ¼Ã‹â€ 43/44à ¯Ã‚ ¼Ã¢â‚¬ °of Chinese M.bovis isolates including the Chinese strain HB0801 (Fig.1). In addition, ST-34 (allelic profile of 11,6,2,2,2,5,3) contains only one strain SZ; while ST-1(allelic profile of 1,1,1,1,1,1,1) represented by strain PG45 was identified (Table 1). Genetic relatedness amongst the 44 Chinese M.bovis strains showed two clades A and B. Clade A contained the majority (97.7%) of isolates (43/44) including the Chinese strain HB0801, while clade B contained one Chinese strain SZ (ST-34). M.bovis PG45 type strain was an outlier of these two clades (Fig.1). The geoBURST and MST analysis clustered 44 Chinese in the clonal complex CC2, whereas reference strain PG45 (ST-1) in CC1 (Table 1) as previously described (Rosales et al., 2015) MLST-2 analysis All 44 M.bovis isolates were examined by MLST-2. The mean GC contents of seven gene fragments ranged from 28.76% (tdk) to 35.61% (gyrB).The number of polymorphic sites per locus ranged from 8 in gyrB (8.66%) to 22(23.91%) in gpsA and a total of 92 polymorphic sites were identified (Table 2). The numbers of alleles identified were 2 for adh-1, gpsA, gyrB, pta2 and tkt and, 3 for gltX. The genetic diversity obtained 0.328 for adh-1 to 0.962 for gpsA (Table 2).   The Chinese strains were distributed into two different sequence types. ST-10 with allelic profile 4,3,3,3,5,3,4 was the most numerically dominant type, comprising 97.7% (43/44) of Chinese isolates; and ST-32 had only one isolate, SZ respectively. All M.bovis isolates tested in this study were clustered into two major clades A and B based on genetic relatedness by UPGMA. Clade A was comprised of 97.7% (43/44) of Chinese isolates including the Chinese strain HB0801. Whereas Clade-B contains one Chinese isolate. Same as above, M.bovis PG45 type strain was an outlier of these two clades (Fig. 2) PFGE typing The 44 Chinese M.bovis strains, and type strain PG45 were subjected to PFGE following the use of restriction enzyme SmaI. All isolates were typeable and the banding profile of the isolates ranged from 6 to 10 bands (from
