However, large-scale studies on pig-associated Staphylococcus aureus in relation to healthy pigs, diseased pigs and environment are scarce. The objective of the present study was to characterize and compare S. aureus isolates from healthy pigs, diseased pigs and environment through antimicrobial susceptibility testing, multiple locus sequence typing, spa typing, and antimicrobial resistance gene screening. Results showed all isolates were susceptible to linezolid and vancomycin. However, 66.7% (104\/156) isolates were multidrug-resistant by displaying resistance to three or more antibiotics and high rates of resistance to penicillin, tetracycline, clindamycin, and clarithromycin were observed. Of the 20 multilocus sequence types (STs) identified among the isolates, ST9, ST188, and ST7 were most commonly isolated from healthy pigs and environment, while ST1 was most commonly isolated from diseased pigs. In total, 17 spa types were represented among the isolates, while t4792 was most commonly isolated from diseased pigs and t899, t189 were most commonly isolated from healthy pigs and environment. In conclusion, the genotypic and epidemiology characteristics observed among the isolates suggest pigs and pork could be important players in S. aureus dissemination.<\/jats:p>","DOI":"10.3390\/antibiotics9120839","type":"journal-article","created":{"date-parts":[[2020,11,24]],"date-time":"2020-11-24T02:34:42Z","timestamp":1606185282000},"page":"839","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Genotypic Characteristics and Correlation of Epidemiology of Staphylococcus aureus in Healthy Pigs, Diseased Pigs, and Environment"],"prefix":"10.3390","volume":"9","author":[{"given":"Yuanyuan","family":"Zhou","sequence":"first","affiliation":[{"name":"School of Food Science and Engineering, South China University of Technology, Guangzhou 510000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhui","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Microbiology, University of Wisconsin-La Crosse, 1725 State Street, La Crosse, WI 54601, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"He","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Food Science and Engineering, South China University of Technology, Guangzhou 510000, China"},{"name":"Research Institute for Food Nutrition and Human Health, Guangzhou 510000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,24]]},"reference":[{"key":"ref_1","first-page":"57","article-title":"Transmission dynamics of methicillin-resistant Staphylococcus aureus in pigs","volume":"4","author":"Vanderhaeghen","year":"2013","journal-title":"Front Microbiol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"14","DOI":"10.3343\/alm.2013.33.1.14","article-title":"Rapid clinical bacteriology and its future impact","volume":"33","author":"Durand","year":"2013","journal-title":"Ann.
