Rev Inst Adolfo Lutz [Internet]. 20º de dezembro de 2020 [citado 28º de março de 2024];79(1):1-9. Disponível em: https://periodicos.saude.sp.gov.br/RIAL/article/view/36027

Resumo

Os protozoários ciliados constituem um grupo onipresente de eucariotos pouco relatados em vegetais
folhosos. O presente estudo teve como objetivo verificar a ocorrência e a diversidade de protozoários
ciliados nas folhas e raízes de três dos vegetais folhosos mais consumidos no Brasil - alface, rúcula
e coentro. As amostras de vegetais foram lavadas por agitação manual (3 minutos) em dois meios
diferentes (água mineral e Solução Salina para Ameba). Após a lavagem, o conteúdo foi incubado
em placas de Petri e alíquotas foram retiradas para identificação microscópica e observação in vivo
dos organismos. Um total de 21 espécies de protozoários ciliados foi encontrado, a maioria das quais
era bacterívora. Tais hortaliças têm sido comumente associadas a surtos transmitidos por alimentos
e os protozoários ciliados que, embora não sejam um problema de saúde pública, podem atuar como
“Cavalos de Tróia” ao abrigar bactérias, vírus além de cistos e oocistos de protozoários o que pode
sugerir uma nova rota para a avaliação da qualidade microbiológica relacionada à cadeia alimentar.
Este é o primeiro relato de protozoários ciliados em folhas verdes consumidas no Brasil.
