[Evaluation of different diagnostic techniques for oocysts of Cryptosporidium baileyi in broiler chickens (Gallus gallus domesticus) fecal samples].
The objective of this work is to evaluate different diagnostic techniques for Cryptosporidium baileyi oocysts in broiler chickens fecal samples infected naturally. So 90 samples were collected and conditioned in bottles with 10% formaline and submitted to Sheater s technique in bright field. Besides it, duplicate smears of the same samples were stained by safranin-methylene blue and modified Ziehl-Neelsen. Among the staining techniques, modified Ziehl-Neelsen got better result in the detention of C. baileyi oocysts in comparison to safranin-methylene blue. In spite of no significant differences among these techniques in the diagnosis of C. baileyi oocysts of fecal samples, bright field presented better results.
