Abstract

Infections by Cryptosporidium spp. in aquatic mammals is a major concern due to the possibility of the waterborne transmission of oocysts. The aim of the present study was to report the occurrence of Cryptosporidium spp. in Antillean manatees (Trichechus manatus) and Amazonian manatees (Trichechus inunguis) from Brazil. Fecal samples were collected and processed using Kinyoun's method. Positive samples were also submitted to the direct immunofluorescence test. The results revealed the presence of Cryptosporidium spp. oocysts in 12.5% (17/136) of the material obtained from the Antillean manatees and in 4.3% (05/115) of the samples from the Amazonian manatees. Cryptosporidium spp. infection was more prevalent in captive animals than in free-ranging specimens.

摘要

由于卵囊存在经水传播的可能性，水生哺乳动物感染隐孢子虫属成为一个主要问题。本研究的目的是报告巴西的安的列斯海牛（Trichechus manatus）和亚马逊海牛（Trichechus inunguis）中隐孢子虫属的感染情况。收集粪便样本并采用金胺酚染色法进行处理。阳性样本还进行了直接免疫荧光试验。结果显示，从安的列斯海牛获取的材料中有12.5%（17/136）存在隐孢子虫属卵囊，从亚马逊海牛的样本中有4.3%（05/115）存在该卵囊。隐孢子虫属感染在圈养动物中比在自由放养的个体中更为普遍。
