Usually, indigenous communities live in extreme poverty and are at risk of acquiring infections. In Brazil, healthcare inequality is observed in this population. To date, there are no reports of CA-MRSA infections, and no active search for asymptomatic S. aureus carriage has been conducted among Brazilian Indians. The aim of this study was to investigate the prevalence of colonization with S. aureus and CA-MRSA among Brazilian Indians. We screened 400 Indians (from near urban areas and remote hamlets) for S. aureus and CA-MRSA colonization. The isolates were submitted to clonal profiling by pulsed-field gel electrophoresis (PFGE), and selected isolates were submitted to multilocus sequence typing (MLST). Among 931 specimens (nasal and oral) from different indigenous individuals in remote hamlets, S. aureus was cultured in 190 (47.6%). Furthermore, CA-MRSA was found in three isolates (0.7%), all SCCmec type IV. PFGE analysis identified 21 clusters among the S. aureus isolates, and MLST analysis showed a predominance of sequence type 5 among these isolates. Our study revealed a higher prevalence of S. aureus carriage among Shanenawa ethnicity individuals (41.1%). Therefore, ethnicity appears to be associated with the prevalence of S. aureus in these populations.<\/jats:p>","DOI":"10.3390\/antibiotics12050862","type":"journal-article","created":{"date-parts":[[2023,5,8]],"date-time":"2023-05-08T04:04:48Z","timestamp":1683518688000},"page":"862","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Staphylococcus aureus and CA-MRSA Carriage among Brazilian Indians Living in Peri-Urban Areas and Remote Communities"],"prefix":"10.3390","volume":"12","author":[{"given":"L\u00edgia Maria","family":"Abra\u00e3o","sequence":"first","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"},{"name":"Nursing Research and Care Practices, Hospital Samaritano Higienopolis, S\u00e3o Paulo 01232-010, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos Magno Castelo Branco","family":"Fortaleza","sequence":"additional","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6834-0085","authenticated-orcid":false,"given":"Carlos Henrique","family":"Camargo","sequence":"additional","affiliation":[{"name":"Center of Bacteriology, Adolfo Lutz Institute\u2014IAL, S\u00e3o Paulo 01246-000, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tha\u00eds Alves","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliane Patr\u00edcia Lino","family":"Pereira-Franchi","sequence":"additional","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danilo Fl\u00e1vio Moraes","family":"Riboli","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biological Sciences, Biosciences Institute, UNESP\u2014Universidade Estadual Paulista, Botucatu 18618-691, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7377-7652","authenticated-orcid":false,"given":"Luiza","family":"Hubinger","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biological Sciences, Biosciences Institute, UNESP\u2014Universidade Estadual Paulista, Botucatu 18618-691, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana F\u00e1vero","family":"Bonesso","sequence":"additional","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7775-6901","authenticated-orcid":false,"given":"Rodrigo","family":"Medeiros de Souza","sequence":"additional","affiliation":[{"name":"Department of Nursing, Federal University of Acre\u2014UFAC, Cruzeiro do Sul 69920-900, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9079-2723","authenticated-orcid":false,"given":"Maria de Lourdes","family":"Ribeiro de Souza da Cunha","sequence":"additional","affiliation":[{"name":"Department of Infectology, Dermatology, Diagnostic Imaging and Radiotherapy, Medical School (FMB) of Sao Paulo State University (UNESP), Botucatu 18618-970, Brazil"},{"name":"Department of Chemical and Biological Sciences, Biosciences Institute, UNESP\u2014Universidade Estadual Paulista, Botucatu 18618-691, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"616","DOI":"10.1128\/CMR.00081-09","article-title":"Community-associated methicillin-resistant Staphylococcus aureus: Epidemiology and clinical consequences of an emerging epidemic","volume":"23","author":"David","year":"2010","journal-title":"Clin.
