Summary. The article focuses on the seasonal dynamics of histomoniasis and trichomoniasis in turkeys on farms in Odesa Region. Studies have shown that pathological changes in turkeys have a pronounced seasonal dependence. In the spring and summer, an increase in the intensity of histomoniasis and trichomoniasis lesions was observed, which is associated with optimal conditions for the development of pathogens. The study found that when turkeys are infected, pathological changes are primarily observed in the cecum, and necrotic processes are noted in the liver. In the acute form of histomoniasis, macroscopic changes in the liver are observed. The autopsy revealed significant lesions in the small intestine and liver, accompanied by characteristic changes including hemorrhagic typhlitis, fibrinous ulcerative inflammation, and fibrinous masses. A histological examination confirmed the presence of hyperemia, diffuse infiltrates, fibrinous changes, and necrosis in the intestinal mucosa and liver. A pathological examination of the turkey corpses revealed a pattern similar to that of histomoniasis and trichomoniasis, with hemorrhagic or fibrinous inflammatory changes in the intestines and liver changes. The data suggest that the combination of these infections complicated the disease

Keywords: Histomonas meleagridis, pathological changes, acute form
