The aim of this study is to detect the prevalence and diagnosis of molecular characteristics of Cryptosporidium infection in handlers of domestic pigeons in Baghdad City. Traditional and molecular diagnostic methods were employed to detect and identify Cryptosporidium species.
Sixty stool samples were collected from the handlers of domestic pigeons, and various techniques, including direct smear, flotation concentration, staining methods, and DNA extraction coupled with nested polymerase chain reaction (PCR), were utilized.
The results obtained from traditional methods indicated an overall infection rate of 55% in handlers of domestic pigeons, while significant variations were noted between male and female handlers. Age group 21-40 years were found to have higher infection rates were found to have higher infection rates. The prevalence of Cryptosporidium also displayed temporal variability throughout the study period. Molecular analysis using nested PCR revealed higher infection rates of 86% in handlers of domestic pigeon samples. Genotyping and phylogenetic analysis identified the presence of Cryptosporidium parvam species in handlers of domestic pigeons, indicating zoonotic transmission potential.
These findings underscore the high prevalence of Cryptosporidium infection among handlers of domestic pigeons in Baghdad City.
本研究旨在检测巴格达市家鸽饲养者中隐孢子虫感染的患病率及分子特征诊断情况。采用传统和分子诊断方法来检测和鉴定隐孢子虫种类。
从家鸽饲养者处收集了60份粪便样本,并运用了多种技术,包括直接涂片、浮选浓缩、染色方法以及结合巢式聚合酶链反应(PCR)的DNA提取技术。
传统方法获得的结果表明,家鸽饲养者的总体感染率为55%,而男性和女性饲养者之间存在显著差异。发现21 - 40岁年龄组的感染率较高。在整个研究期间,隐孢子虫的患病率也呈现出时间上的变化。使用巢式PCR进行的分子分析显示,家鸽样本饲养者的感染率更高,为86%。基因分型和系统发育分析确定在家鸽饲养者中存在微小隐孢子虫物种,表明存在人畜共患病传播潜力。
这些发现强调了巴格达市家鸽饲养者中隐孢子虫感染的高患病率。
