The parasites infesting pigs and pig farmers on family farms in Rio de Janeiro city, Brazil, were analyzed, and extension activities were carried out to impart information about parasites. Between 2020 and 2021, fecal samples were collected from 180 pigs as well as ear scrapings from 142 pigs. In addition, 34 stool specimens from farmers and their families were analyzed. The collected material was processed by parasitological techniques. Parasites were detected in 86.1% of the pigs, forms of phylum Ciliophora (70.5%), strongylids (56.7%), (44.4%), coccidia (38.3%) and (32.2%). var. were identified in 3.5% of the pigs. An analysis of infections by age group revealed that the general frequency of phylum Ciliophora and strongylid parasites was statistically significant. Other factors also associated with the frequency of the parasites included the type of food fed to the pigs, cleaning of the facilities, care of piglets and type of facility. The frequency of intestinal parasites of farmers themselves was low; however, the high rate of parasite infections detected in pigs highlighted the precarious conditions of hygiene of the farms. Lastly, the farmers' participation in extension activities was a step forward in actions to improve their farm management.
对巴西里约热内卢市家庭农场中感染猪和养猪户的寄生虫进行了分析，并开展了推广活动以传播有关寄生虫的信息。在2020年至2021年期间，从180头猪身上采集了粪便样本，以及从142头猪身上采集了耳垢样本。此外，还分析了34份来自农民及其家人的粪便标本。所收集的材料采用寄生虫学技术进行处理。在86.1%的猪身上检测到寄生虫，纤毛虫门（70.5%）、圆线虫（56.7%）、（44.4%）、球虫（38.3%）和（32.2%）。在3.5%的猪身上鉴定出变种。按年龄组进行的感染分析显示，纤毛虫门和圆线虫寄生虫的总体感染频率具有统计学意义。与寄生虫感染频率相关的其他因素包括喂给猪的食物类型、设施清洁情况、仔猪护理以及设施类型。农民自身肠道寄生虫的感染频率较低；然而，在猪身上检测到的高寄生虫感染率凸显了农场卫生条件的不稳定。最后，农民参与推广活动是改善农场管理行动中的一个进步。
