Identificação bioquímica de bactérias potencialmente patogênicas e zoonóticas em tartarugas pretas (Chelonia mydas) do Pacífico mexicano
Palavras-chave:
Bacteriologia, microbiota, patógenosResumo
As tartarugas marítimas naturalmente têm microbiota gastrointestinal, no entanto, o comportamento oportunista e a patogenicidade de algumas bactérias nessas espécies também foram relatadas. Portanto, é importante gerar informações sobre os possíveis riscos para tartarugas e saúde humana. Cinco monitores mensais foram realizados com capturas de Chelonia Mydas no complexo lagunar de Ojo de Liebre. Eles eram praticados exames físicos e suas morfometrias foram registradas e sua taxa de condição corporal foi calculada. Zaragatoa orais e cloacais foram realizadas que foram semeadas em McConkey e Mídia TCBS. Agentes bacterianos foram isolados e identificados pelo sistema API®20E. As porcentagens de abundância e prevalência de cada microrganismo foram calculadas. Finalmente, a relação entre o tamanho das tartarugas e a presença dos microrganismos foi determinada. 178 Chelonia Mydas foram capturadas, 523 isolados de enterobactérias gramnegativas de sete espécies diferentes foram obtidas. A presença de proteobactérias no Chelonia Mydas não estava relacionada à sua classe etária. Dentro dos microrganismos encontrados, Vibrio Fluvialis e Burkholderia Cepacia são zoonóticos. Esses estudos permitem entender o papel dos microorganismos em doenças de populações selvagens e riscos de saúde pública associados ao seu consumo ilegal.
