Cryptosporidiosis is a worldwide zoonosis caused by Cryptosporidium spp., sometimes leading to severe diarrhea in humans and animals. In the present study, 311 parrots, belonging to four species, namely, Budgerigars (Melopsittacus undulatus), Lovebirds (Agapornis sp.), Alexandrine parakeets (Psittacula eupatria), and Cockatiel (Nymphicus hollandicus), from Beijing and Weifang cities, were examined for Cryptosporidium spp. infection. Blood samples of each bird were examined using enzyme linked immunosorbent assay (ELISA) and fecal samples were examined by Sheather's sugar flotation technique. Prevalence of Cryptosporidium infection were 3.22% (10/311) and 0.64% (2/311) by ELISA and Sheather's sugar flotation technique, respectively. Seroprevalence of Cryptosporidium infection in different breeds varied from 0 to 15.39%. Sequencing analysis showed that both positive samples from fecal samples belonged to Cryptosporidium avian genotype V. This is the first report of Cryptosporidium avian genotype V in Budgerigars. The results of the present study provided foundation-data for prevention and control of cryptosporidiosis in pet birds in China.
隐孢子虫病是一种由隐孢子虫属引起的全球性人畜共患病,有时会导致人和动物严重腹泻。在本研究中,对来自北京和潍坊的311只鹦鹉进行了隐孢子虫属感染检测,这些鹦鹉分属于四个品种,即虎皮鹦鹉(Melopsittacus undulatus)、牡丹鹦鹉(Agapornis sp.)、亚历山大鹦鹉(Psittacula eupatria)和鸡尾鹦鹉(Nymphicus hollandicus)。对每只鸟的血液样本采用酶联免疫吸附测定(ELISA)进行检测,粪便样本采用谢泽尔氏糖浮选法进行检测。ELISA法和谢泽尔氏糖浮选法检测隐孢子虫感染的阳性率分别为3.22%(10/311)和0.64%(2/311)。不同品种鹦鹉隐孢子虫感染的血清阳性率在0至15.39%之间。测序分析表明,粪便样本中的两个阳性样本均属于隐孢子虫鸟类基因型V。这是虎皮鹦鹉中首次报道隐孢子虫鸟类基因型V。本研究结果为我国宠物鸟隐孢子虫病的防控提供了基础数据。
