Abstract：
Cryptosporidium and Giardia are recognized as significant etiological agents of diarrheal outbreaks in humans as these parasites may be transmitted through the ingestion of water and food contaminated with feces of human or animal origin. However, surveillance studies on the role of animal reservoirs in the transmission of Cryptosporidium and Giardia are deemed insufficient and the complete dimension of the problem contributing to contamination in an agricultural setting is unknown. This study aimed to assess the presence of Cryptosporidium and Giardia in domesticated animals from selected farms in the agricultural provinces of Laguna and Quezon in Southern Luzon, Philippines. Using immunofluorescence assay, an overall 85.7% incidence of protozoan infection was recorded among the animals (N = 161). Of these, 77.0 and 73.9% were positive for Cryptosporidium and Giardia, respectively. Highest incidence (95.83%) of Cryptosporidium was documented in swine and the highest incidence (89.47%) of Giardia was observed in ruminants. Analyses revealed significant differences in the incidence of the protozoan parasites among animals with different containment status, water source, age group, and sex. On the other hand, farm workers\' knowledge on parasite transmission was negatively correlated (p = 0.001) to parasite incidence. With the scarcity of data about Cryptosporidium and Giardia in farm-raised animals in the Philippines, the information obtained from this study will be vital for protozoan source tracking and further control interventions against Cryptosporidium and Giardia infections.
摘要：
隐孢子虫和贾第鞭毛虫被认为是人类腹泻暴发的重要病原体，因为这些寄生虫可能通过摄入被人类或动物粪便污染的水和食物而传播。然而,关于动物水库在隐孢子虫和贾第鞭毛虫传播中的作用的监测研究被认为是不够的，在农业环境中导致污染的问题的完整层面是未知的。这项研究旨在评估南吕宋岛拉古纳和奎松农业省部分农场家养动物中隐孢子虫和贾第鞭毛虫的存在。菲律宾。用免疫荧光法,动物中原生动物感染的总体发生率为85.7%(N=161).其中,隐孢子虫和贾第鞭毛虫阳性为77.0%和73.9%，分别。在猪中记录了隐孢子虫的最高发病率（95.83％），在反刍动物中观察到贾第鞭毛虫的最高发病率（89.47％）。分析显示，在不同收容状态的动物中，原生动物寄生虫的发生率存在显着差异。水源,年龄组,和性爱。另一方面,农场工人对寄生虫传播的了解与寄生虫发病率呈负相关(p=0.001)。由于菲律宾农场饲养的动物中有关隐孢子虫和贾第鞭毛虫的数据很少，从这项研究中获得的信息对于追踪原生动物来源以及对隐孢子虫和贾第鞭毛虫感染的进一步控制干预至关重要.
