Resumo

Em diversas condições fisiológicas e patológicas, o bacterioma uterino em mamíferos gera debates a respeito da presença de um microbioma permanente. Nesse sentido, os estudos vêm sendo conduzidos sobre o microbioma do trato reprodutivo em algumas espécies, utilizando técnicas modernas de biologia molecular. Entretanto, essas informações ainda não foram descritas em gatas. Desta forma, este estudo objetivou investigar a presença de um bacterioma uterino em gatas saudáveis e não gestantes, através da investigação do gene 16S rRNA. Fragmentos uterinos foram coletados de cinco gatas saudáveis após histerectomia total com salpingo-ooforectomia. Após a extração do DNA, as amostras foram submetidas à PCR convencional para amplificação das regiões V3 e V4 do gene 16S rRNA. Nossas análises revelaram ausência de amplificação detectável das regiões V3 e V4 do gene 16S rRNA em todas as amostras. Esses achados reforçam a hipótese de que o endométrio felino pode ser estéril ou abrigar uma biomassa microbiana em níveis ultrabaixos. Estudos futuros com tamanhos amostrais maiores e mais representativos são essenciais para confirmar esses resultados e compreender melhor o microbioma uterino em diferentes condições fisiológicas.
