The aim of this study was to analyze the pleomorfism of Cryptosporidium spp. oocysts isolated from calves feces throughout the comparison of two diagnostic techniques. One hundred of cattle feces were collected and the samples were submitted to both flotation sucrose centrifugation and to Ziehl-Neelsen modified tests. The results obtained showed a statistically significant reduction on the size of the Cryptosporidium oocysts observed through Ziehl-Neelsen technique when compared to the flotation sucrose centrifugation technique, and that the difference on the diameter of the oocysts suggests the there were different species of Cryptosporidium circulating in the animals analyzed.
本研究的目的是通过比较两种诊断技术，分析从犊牛粪便中分离出的隐孢子虫属卵囊的多态性。收集了100份牛粪样本，并将其分别进行蔗糖漂浮离心和改良齐-尼氏染色试验。结果表明，与蔗糖漂浮离心技术相比，通过齐-尼氏技术观察到的隐孢子虫卵囊大小在统计学上有显著减小，并且卵囊直径的差异表明在所分析的动物中存在不同种类的隐孢子虫在传播。
