Abstract:
... Enumeration of Eimeria oocysts is a common practice in monitoring coccidiosis in turkeys; however, the conventional method of manual microscopic examination of Eimeria oocysts is time-consuming. Previously, we used flow cytometry (FCM) to enumerate and speciate coccidia affecting chickens and here, we extended those findings to turkey coccidia species, E. adenoides and E. meleagrimitis. Using FCM, ...

Abstract:
... Anticoccidial drug resistance in coccidia has been known since the 1960s, and experimental selection for resistance in the laboratory has been done for most available products. However, routine testing for sensitivity in field isolates has only begun in recent years. Poultry producers are faced with greater challenges because of consumer preferences for ‘antibiotic-free’ products and a lack of new ...

Abstract:
... Oral antibody to interleukin-10 (anti-IL-10) enhances the intestinal immune defense against Eimeria. The sulfur amino acids methionine and cysteine (M+C) play essential roles in inducing and maintaining protective immune responses during intestinal infections. Hence, increased dietary M+C may support the anti-IL-10-induced intestinal immunity to Eimeria. Broilers (n = 640) were arranged in a 2 × 2 ...
