is an obligate intracellular parasite that infects a wide range of animal species, including humans and livestock. Contamination can have significant health, economic and epidemiological consequences. Birds in general, and poultry in particular, appear to play an important role in the epidemiology and circulation of the parasite. The aim of this study was to determine, for the first time, the seroprevalence of in chicken in the Marrakech-Safi region.
Sera were collected between January 2019 and March 2020 from 486 chickens from three types of farming: 122 traditional (domestic) chickens, 109 free-range chickens, and 255 commercial (battery) chickens intended for consumption in the Marrakech-Safi region. Immunoglobulin Y (IgY) testing was performed by ELISA using a total antigen.
The mean seroprevalence of in chicken in the study region was 30.65%. This study also showed a significant association (p<0.0001) between seroprevalence and type of farming: domestic chickens had a higher seroprevalence than free-range and commercial chickens.The high seropositivity in chicken could be explained by the widespread presence of oocysts and/or cysts in their environment and diet.
Consumption of undercooked or uncooked poultry products may be a source of potential contamination for humans and carnivores, including cats.
是一种专性细胞内寄生虫，可感染包括人类和家畜在内的多种动物物种。污染会产生重大的健康、经济和流行病学后果。一般来说鸟类，特别是家禽，似乎在该寄生虫的流行病学和传播中起着重要作用。本研究的目的是首次确定马拉喀什-萨菲地区鸡群中的血清阳性率。
在2019年1月至2020年3月期间，从马拉喀什-萨菲地区三种养殖类型的486只鸡中采集血清：122只传统（家养）鸡、109只自由放养的鸡和255只用于消费的商业（笼养）鸡。使用总抗原通过酶联免疫吸附测定（ELISA）进行免疫球蛋白Y（IgY）检测。
研究区域内鸡群中的平均血清阳性率为30.65%。本研究还表明血清阳性率与养殖类型之间存在显著关联（p<0.0001）：家养鸡的血清阳性率高于自由放养的鸡和商业鸡。鸡的高血清阳性率可以通过其环境和饮食中广泛存在的卵囊和/或包囊来解释。
食用未煮熟或生的家禽产品可能是人类和食肉动物（包括猫）潜在污染的来源。
