Yet, studies on this species are scarce. Twenty-seven S. coagulans and one S. schleiferi, corresponding to all pyoderma-related isolations from these two species at two veterinary laboratories in Lisbon, Portugal, between 1999 and 2018 (Lab 1) or 2018 (Lab 2), were analyzed. Isolates were identified by the analysis of the nuc gene and urease production. Antibiotic susceptibility towards 27 antibiotics was evaluated by disk diffusion. Fourteen antibiotic resistance genes were screened by PCR. Isolates were typed by SmaI-PFGE. Two S. coagulans isolates (2\/27, 7.4%) were methicillin-resistant (MRSC, mecA+) and four (4\/27, 14.8%) displayed a multidrug-resistant (MDR) phenotype. We observed resistance to penicillin (17\/27, 63.0%), fluoroquinolones (11\/27, 40.7%), erythromycin and clindamycin (3\/27, 11.1%), fusidic acid (3\/27, 11.1%) and tetracycline (1\/27, 3.7%). The blaZ and erm(B) genes were carried by 16 and 1 isolates resistant to penicillin and erythromycin\/clindamycin, respectively. Only three S. coagulans carried plasmids. The single S. schleiferi isolate presented an MDR phenotype. SmaI-PFGE revealed a limited genetic diversity of S. coagulans, with a predominant lineage present from 2001 to 2018. This study describes the first MRSC causing canine infection in Portugal and reveals a high burden of antimicrobial resistance, with the emergence of MDR phenotypes within the main lineages.<\/jats:p>","DOI":"10.3390\/antibiotics10050518","type":"journal-article","created":{"date-parts":[[2021,5,2]],"date-time":"2021-05-02T08:05:21Z","timestamp":1619942721000},"page":"518","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Phenotypic and Molecular Traits of Staphylococcus coagulans Associated with Canine Skin Infections in Portugal"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4096-2410","authenticated-orcid":false,"given":"Sofia Santos","family":"Costa","sequence":"first","affiliation":[{"name":"Global Health and Tropical Medicine (GHTM), Instituto de Higiene e Medicina Tropical (IHMT), Universidade Nova de Lisboa (UNL), Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Val\u00e9ria","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Global Health and Tropical Medicine (GHTM), Instituto de Higiene e Medicina Tropical (IHMT), Universidade Nova de Lisboa (UNL), Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Serrano","sequence":"additional","affiliation":[{"name":"Global Health and Tropical Medicine (GHTM), Instituto de Higiene e Medicina Tropical (IHMT), Universidade Nova de Lisboa (UNL), Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Constan\u00e7a","family":"Pomba","sequence":"additional","affiliation":[{"name":"Centre of Interdisciplinary Research in Animal Health (CIISA), Faculty of Veterinary Medicine, University of Lisbon, Avenida da Universidade T\u00e9cnica, 1300-477 Lisboa, Portugal"},{"name":"GeneVet, Laborat\u00f3rio de Diagn\u00f3stico Molecular Veterin\u00e1rio, Rua Quinta da Nora Loja 3B, 2790-140 Carnaxide, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3536-2733","authenticated-orcid":false,"given":"Isabel","family":"Couto","sequence":"additional","affiliation":[{"name":"Global Health and Tropical Medicine (GHTM), Instituto de Higiene e Medicina Tropical (IHMT), Universidade Nova de Lisboa (UNL), Rua da Junqueira 100, 1349-008 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"163-e43","DOI":"10.1111\/vde.12118","article-title":"Guidelines for the diagnosis and antimicrobial therapy of canine superficial bacterial folliculitis (Antimicrobial Guidelines Working Group of the International Society for Companion Animal Infectious Diseases)","volume":"25","author":"Hillier","year":"2014","journal-title":"Vet.
