Abstract

Cryptosporidium protozoa genus are parasites that cause acute enteric disease in young and immunocompromised animals, resulting in anorexia, loss and decrease in weight gain, and, in severe cases, death. Therefore, this study aimed: i) to determine the occurrence of Cryptosporidium spp. in calves with clinical diarrhea in different regions of Santa Catarina, Brazil; ii) to evaluate the risk factors involved with the frequency of infection. iii) to determine the species most involved with the disease in the region. For this, 425 samples were collected in 141 dairy farms, from animals with ages ranging from 0 to 150 days. For this purpose, the samples were submitted to the modified Ziehl-Neelsen technique, with molecular analysis of the positive samples being performed. It was observed 62.1% occurrence of Cryptosporidium spp. in this sampling, especially between 8 to 15 days. Regarding the risk factors evaluated, such as age, management, facilities, water source and Koppen climate (CFA and CFB), none showed statistical significance. Samples positive by the Ziehl-Neelsen technique (32 samples) were randomly selected for molecular diagnosis. Of these, 10 were sequenced, allowing the identification of Crypstosporidium parvum in 6 samples. However, this study proves the existence and high occurrence of the protozoan in different regions of the state of Santa Catarina, Brazil.

腹泻犊牛隐孢子虫感染:巴西圣卡塔琳娜州的发生和危险因素
隐孢子虫原生动物属是一种寄生虫,可在幼龄和免疫功能低下的动物中引起急性肠道疾病,导致厌食、体重减轻和体重增加减少,严重时可导致死亡。因此,本研究旨在:i)确定巴西圣卡塔琳娜州不同地区临床腹泻犊牛隐孢子虫的发生率;Ii)评估与感染频率有关的危险因素。Iii)确定该地区与该疾病关系最密切的物种。为此,从141个奶牛场收集了425个样本,来自0到150天的动物。为此,将样品提交到改进的Ziehl-Neelsen技术,并对阳性样品进行分子分析。该样本隐孢子虫感染率为62.1%,8 ~ 15 d间感染率最高。年龄、管理、设施、水源和Koppen气候(CFA和CFB)等风险因素评价均无统计学意义。随机选取Ziehl-Neelsen技术阳性样本32份进行分子诊断。对其中10个样本进行了测序,在6个样本中鉴定出细小隐孢子虫。然而,本研究证明了该原虫在巴西圣卡塔琳娜州不同地区的存在和高发生率。
