The purpose of this study was to examine the prevalence and characterisation of multiresistant bacteria in pig samples. Methods: 224 samples of pig livestock were taken at the slaughterhouse on the island of Tenerife. A nasal and a rectal sample were collected from each pig. The presence of methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant Staphylococcus coagulase-negative (MRCoNS), vancomycin-resistant Enterococcus (VRE), extended-spectrum \u00df-lactamase-producing Enterobacteriaceae (BLEE), carbapenemase-producing Enterobacteriaceae (CPE), and colistin-resistant Enterobacteriaceae was investigated. The resistance genes of the isolated bacteria were characterised by specific PCRs depending on the microorganism to be studied, and in vitro antimicrobial resistance was determined using the broth microdilution method (Vitek\u00ae2 system bioM\u00e9rieux\u00ae, Nurtingen, Germany). Results: MRSA prevalence was 73.21% (164 isolates). MRCoNS prevalence was 9.8% (22 isolates), S. sciuri being the prevalent species. Six isolates presented a 2.7% prevalence of extended-spectrum \u00df-lactamase-producing Escherichia coli (BLEE) in the CTX-M-1 group. No vancomycin-resistant Enterococcus (VRE), carbapenemase-producing Enterobacteriaceae (CRE), or colistin-resistant Enterobacteriaceae were isolated. Conclusion: we found a high presence of multiresistant bacteria, suggesting the need for increased control and surveillance of this type of strains in pig livestock and a better understanding of the possible transmission routes of these microorganisms through livestock products.<\/jats:p>","DOI":"10.3390\/vetsci9060269","type":"journal-article","created":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T08:01:18Z","timestamp":1654243278000},"page":"269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence and Characterisation of Multiresistant Bacterial Strains Isolated in Pigs from the Island of Tenerife"],"prefix":"10.3390","volume":"9","author":[{"given":"Rossana","family":"Abreu","sequence":"first","affiliation":[{"name":"Department of Preventive Medicine and Public Health, University of La Laguna, Campus de Ofra, s\/n, 38071 Santa Cruz de Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3553-3213","authenticated-orcid":false,"given":"Cristobalina","family":"Rodr\u00edguez-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Public Health, University of La Laguna, Campus de Ofra, s\/n, 38071 Santa Cruz de Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz","family":"Castro-Hernandez","sequence":"additional","affiliation":[{"name":"Microbiology and Infection Control Service, University Hospital of the Canary Islands, Canary Islands, Tenerife, 38320 San Crist\u00f3bal de La Laguna, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Lecuona-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Microbiology and Infection Control Service, University Hospital of the Canary Islands, Canary Islands, Tenerife, 38320 San Crist\u00f3bal de La Laguna, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Carlos","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Canary Islands Health Service, Canary Islands, 38004 Santa Cruz de Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yurena","family":"Rodr\u00edguez-Novo","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Nursing Section, University of La Laguna, Tenerife, 38200 La Laguna, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3015-4452","authenticated-orcid":false,"given":"Maria de los Angeles","family":"Arias Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Public Health, University of La Laguna, Campus de Ofra, s\/n, 38071 Santa Cruz de Tenerife, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1645","DOI":"10.1111\/risa.13495","article-title":"Risk of Antibiotic-Resistant Staphylococcus aureus Dispersion from Hog Farms: A Critical Review","volume":"8","author":"George","year":"2020","journal-title":"Risk Anal."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"771510","DOI":"10.3389\/fcimb.2021.771510","article-title":"Antibiotic Resistance: One Health One World Outlook","volume":"11","author":"Aslam","year":"2021","journal-title":"Front.
