The sera were examined for anti-<jats:italic>T<\/jats:italic>. <jats:italic>gondii<\/jats:italic> antibodies using the indirect hemagglutination test. The brains and hearts of seven seropositive cats were ground, and peptide digestion was performed for bioassay in mice. <jats:italic>Toxoplasma gondii<\/jats:italic> was isolated in 5\/7 (71.42%) of seropositive cats. In these isolates, the parasite was genotyped using the Polymerase chain reaction, associated with the DNA fragment polymorphism obtained by restriction enzyme PCR-RFLP technique with 11 markers (SAG1, 5\u2019-SAG2, 3\u2019-SAG2, alt. SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, Apico, and CS3) and 15 microsatellite markers (TUB-2, W35, TgM-A, B18, B17, M33, IV.1, XI.1, M48, M102, N60, N82, AA, N61, N83). The analysis of the isolates by PCR-RFLP revealed five distinct genotypes. Three of these genotypes have never been reported before; one corresponded to the TgDgCo13 genotype, and one incomplete genotype. In genotyping analysis using microsatellite markers, it was observed that the isolates showed atypical alleles in the typing and fingerprint markers. This revealed five atypical genotypes. The typing marker B17 showed the highest degree of atypia. This study is the first to report the genotyping of <jats:italic>T<\/jats:italic>. <jats:italic>gondii<\/jats:italic> obtained from naturally infected cats in Bahia, Northeast Brazil. The genotypes found in this study were different from those found in other studies conducted in Bahia, which included different species of animals. None of the clonal lineages I, II, or III were found. This study demonstrates the diversity of <jats:italic>T<\/jats:italic>. <jats:italic>gondii<\/jats:italic> in the study region, with the presence of unusual genotypes, reaffirming the genetic variability of the parasite in Brazil.<\/jats:p>","DOI":"10.1371\/journal.pone.0253630","type":"journal-article","created":{"date-parts":[[2021,10,5]],"date-time":"2021-10-05T19:46:14Z","timestamp":1633463174000},"page":"e0253630","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":8,"title":["Presence of atypical genotypes of Toxoplasma gondii isolated from cats in the state of Bahia, Northeast of Brazil"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1181-2277","authenticated-orcid":true,"given":"Ana Graziela de Jesus","family":"Deir\u00f3","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danielle Paschoal","family":"do Prado","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iuri Prates","family":"Sousa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele de Santana","family":"Rocha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Alves","family":"Bezerra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernanda Amato","family":"Gaiotto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George Rego","family":"Albuquerque","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandre Dias","family":"Munhoz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,10,5]]},"reference":[{"key":"pone.0253630.ref001","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1016\/j.vetpar.2004.09.005","article-title":"Toxoplasmosis-a waterborne zoonosis","volume":"126","author":"JP Dubey","year":"2004","journal-title":"Vet Parasitol"},{"key":"pone.0253630.ref002","doi-asserted-by":"crossref","first-page":"1375","DOI":"10.1017\/S0031182012000765","article-title":"Toxoplasmosis in humans and animals in Brazil: high prevalence, high burden of disease and epidemiology","volume":"139","author":"JP Dubey","year":"2012","journal-title":"Parasitology"},{"key":"pone.0253630.ref003","doi-asserted-by":"crossref","first-page":"467","DOI":"10.1111\/j.1550-7408.2008.00345.x","article-title":"The history of Toxoplasma gondii\u2014the first 100 years","volume":"556","author":"P.
