A total of 190 isolates were analyzed and 42.3, 43.9 and 23.6% of them were positive for <jats:italic>blaZ<\/jats:italic> gene in buffalo, goat and sheep, respectively. Regarding the animal groups, in goats, amoxicillin was the antimicrobial with highest resistance index (72.7%), followed by penicillin G in buffaloes (51.9%) and ampicillin in sheep (43.1%). With regard to multiple antimicrobial resistance, 30.8% of NAS isolates from buffalo milk samples, 25.8% from goats and 25.0% from sheep presented multidrug-resistance. In the minimum inhibitory concentration (MIC) technique, amoxicillin MIC<jats:sub>50<\/jats:sub> and MIC<jats:sub>90<\/jats:sub> were 64 and 128 \u03bcg\/ml, respectively, among isolates of the three animal species. In conclusion, high rates of resistance to beta-lactams are presented among NAS isolated from mastitis cases in buffaloes, goats and sheep in Northeast region of Brazil. These results provide an alert to animal and human health researchers, suggesting that the frequency of NAS needs to be reduced because they carry resistance genes which might increase the existing levels of antimicrobial resistance.<\/jats:p>","DOI":"10.1017\/s0022029920000771","type":"journal-article","created":{"date-parts":[[2020,9,7]],"date-time":"2020-09-07T09:24:13Z","timestamp":1599470653000},"page":"290-294","source":"Crossref","is-referenced-by-count":14,"title":["Antimicrobial resistance profile of non-aureus <i>Staphylococci<\/i> isolates from buffalo, goat and sheep mastitis in the Northeast region of Brazil"],"prefix":"10.1017","volume":"87","author":[{"given":"Andr\u00e9 de Souza","family":"Santos","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D\u00e9bora Costa Viegas de","family":"Lima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atzel Candido Acosta","family":"Abad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pollyanne Raysa Fernandes de","family":"Oliveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Givanildo da","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guilherme Santana de","family":"Moura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda Tha\u00eds Ferreira","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vin\u00edcius da Silva","family":"Amorim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateus Matiuzzi da","family":"Costa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rinaldo Aparecido","family":"Mota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2020,9,7]]},"reference":[{"key":"S0022029920000771_ref10","doi-asserted-by":"publisher","DOI":"10.1590\/S0100-736X2012000900008"},{"key":"S0022029920000771_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetmic.2008.09.011"},{"key":"S0022029920000771_ref8","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.46.1.165-170.1983"},{"key":"S0022029920000771_ref3","first-page":"9","article-title":"Clinical characteristics, resistance and virulence factors in Staphylococcus aureus","volume":"3","author":"Dias","year":"2015","journal-title":"Acta Scientiarum \u2013 Technology"},{"key":"S0022029920000771_ref5","doi-asserted-by":"publisher","DOI":"10.1097\/MRM.0b013e3283587727"},{"key":"S0022029920000771_ref1","doi-asserted-by":"publisher","DOI":"10.1590\/S0100-736X2016000700001"},{"key":"S0022029920000771_ref2","volume-title":"Performance Standards for Antimicrobial Susceptibility Testing","year":"2015"},{"key":"S0022029920000771_ref4","doi-asserted-by":"publisher","DOI":"10.17305\/bjbms.2014.3.109"},{"key":"S0022029920000771_ref11","volume-title":"Laboratory Handbook on Bovine Mastitis","year":"2017"},{"key":"S0022029920000771_ref14","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.05594-11"},{"key":"S0022029920000771_ref12","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2011-4938"},{"key":"S0022029920000771_ref6","doi-asserted-by":"publisher","DOI":"10.1590\/S0100-736X2012000800012"}],"container-title":["Journal of Dairy Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022029920000771","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,9,28]],"date-time":"2020-09-28T05:26:19Z","timestamp":1601270779000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022029920000771\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8]]},"references-count":12,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2020,8]]}},"alternative-id":["S0022029920000771"],"URL":"https:\/\/doi.org\/10.1017\/s0022029920000771","relation":{},"ISSN":["0022-0299","1469-7629"],"issn-type":[{"value":"0022-0299","type":"print"},{"value":"1469-7629","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8]]}}}
