ABSTRACT
Abstract Cryptosporidium is a zoonotic parasite that causes diarrhea in a broad range of animals, including deer. Little is known about the prevalence and genotype of Cryptosporidium spp. in Père David's deer. In this study, 137 fecal samples from Père David's deer were collected between July 2017 and August 2018 in the Dafeng Reserve and analyzed for Cryptosporidium spp. by nested-PCR based on the small subunit ribosomal RNA (SSU rRNA) gene, followed by sequence analyses to determine the species. The 60 kDa glycoprotein (gp60) gene was used to characterize Cryptosporidium spp. Among 137 samples, 2 (1.46%) were positive for Cryptosporidium spp. according to SSU rRNA gene sequencing results. Both samples belonged to the Cryptosporidium deer genotype, with two nucleotide deletions and one nucleotide substitution. The prevalence data and molecular characterization of this study provide basic knowledge for controlling and preventing Cryptosporidium infections in Père David's deer in this area.
RESUMO
Resumo Cryptosporidium é um parasita zoonótico que causa diarreia em uma ampla gama de animais, incluindo veados. Pouco se sabe sobre a prevalência e o genótipo de Cryptosporidium spp. no cervo de Père David. Neste estudo, 137 amostras fecais do cervo de Père David foram coletadas entre julho de 2017 e agosto de 2018, na Reserva Dafeng, e analisadas para Cryptosporidium spp. por nested-PCR baseado no gene do RNA ribossômico da subunidade pequena (SSU rRNA), seguido de análises de sequências para determinar as espécies. O gene da glicoproteína de 60 kDa (gp60) foi utilizado para caracterizar Cryptosporidium spp. Dentre as 137 amostras, 2 (1,46%) foram positivas para Cryptosporidium spp. de acordo com os resultados do sequenciamento gênico de SSU rRNA. Ambas as amostras pertenciam ao genótipo do cervo Cryptosporidium, com duas deleções nucleotídicas e uma substituição nucleotídica. Os dados de prevalência e a caracterização molecular deste estudo fornecem conhecimentos básicos para controlar e prevenir infecções por Cryptosporidium nos cervos de Père David nessa.
