Intestinal parasites, helminths, and protozoa challenge health and welfare of pigs and deteriorate the sustainability of swine farms leading to monetary losses. A multicentric survey was conducted for approximately one year. Overall, 1150 fecal samples were collected from eight intensive farms in Greece at regular intervals and examined by flotation and Ziehl-Neelsen techniques. Age, season, and time of last recorded antiparasitic treatment were assessed as possible risk factors using binary regression models. The overall prevalence of intestinal parasitism in pigs was 44.7%. The most frequently detected parasites in the studied population were the protozoa (37.8%), followed by spp. (8.3%), (6.0%), and the nematodes (3.7%), (2.5%), and spp. (1.4%). Distribution of intestinal parasites in different age groups was as expected. In autumn, the prevalence of infection enhanced whereas the prevalence of spp. and infections increased in spring. Time of last recorded antiparasitic treatment influenced and infection levels. Our results demonstrated that swine intestinal parasitism in intensive farms of Greece seems to be relatively common and highlighted the importance of proper laboratory examinations, as well as the need for tailored made control programs.
肠道寄生虫、蠕虫和原生动物对猪的健康和福利构成挑战，并降低了养猪场的可持续性，导致经济损失。进行了一项为期约一年的多中心调查。总体而言，定期从希腊的八个集约化农场收集了1150份粪便样本，并通过浮选和齐尔-尼尔森技术进行检查。使用二元回归模型评估年龄、季节和最后一次记录的抗寄生虫治疗时间作为可能的风险因素。猪肠道寄生虫感染的总体患病率为44.7%。在研究人群中最常检测到的寄生虫是原生动物（37.8%），其次是 spp.（8.3%）、 （6.0%），以及线虫 （3.7%）、 （2.5%）和 spp.（1.4%）。不同年龄组肠道寄生虫的分布符合预期。在秋季， 感染的患病率增加，而在春季， spp.和 感染的患病率增加。最后一次记录的抗寄生虫治疗时间影响了 和 感染水平。我们的结果表明，希腊集约化农场的猪肠道寄生虫感染似乎相对普遍，并强调了适当实验室检查的重要性，以及制定量身定制的控制计划的必要性。
