Sažetak
The progression of coccidiosis provoked by E. adenoeides was followed in turkey poults given ochratoxin A (OTA) in feed. More heavy and rapid progress of coccidiosis occurred in OTA-treated turkey poults than in those fed an OTA-free diet, as can be seen from the higher levels of oocyst and lesion indices and more rapid mortality in such birds. The concentration of total protein in serum was significantly increased in turkey poults infected with E. adenoeides and simultaneously given OTA. The serum concentration of uric acid was significantly increased in all experimental groups, especially in those exposed to OTA, and most notably in the group additionally infected with E. adenoeides. OTA induced degenerative changes in kidneys, liver and heart as well as depletion of lymphoid tissue in the lymphoid organs and a decrease in body mass. Coccidiosis also induced a growth depression in addition to caecal haemorrhages. Impairment of kidney function, histopathological changes and general growth depression were stronger when turkey poults infected with E. adenoeides were also given OTA.
