Objective:To identify the genotypes of prevalent Cryptosporidia in broiler chickens in Lorestan province,Iran.Methods:A total of 1 000 fecal and 1 000 trachea samples were collected from chickens.Smears from both fecal and tracheal samples were stained with modified ZiehlNeelsen method and nested PCR-RFTP according to amplification of 18S rRNA gene using Ssp1 and Vsp 1 restriction enzymes and DNA sequencing.Results:From the examined chickens0.7%was positive for Cryptosporidium,Infection was present in 0.3%fecal samples and also in0.5%trachea.Only 0.3%of simultaneous infections in fecal and tracheal samples were observed.Nested PCR of our isolates demonstrated Cryptosporidium baileyi.Conclusions:In our work,low rate of Cryptosporidium baileyi infection was detected,but in critical situations and our poor management circumstances,cryptosporidiosis occurs in serious feature especially in immune suppressed individuals.
Objective: To identify the genotypes of prevalent Cryptosporidia in broiler chickens in Lorestan province, Iran. Methods: A total of 1 000 fecal and 1 000 trachea samples were collected from chickens. Meths from both fecal and tracheal samples were stained with modified ZiehlNeelsen method and nested PCR-RFTP according to amplification of 18S rRNA gene using Ssp1 and Vsp 1 restriction enzymes and DNA sequencing. Results: From the examined chickens 0.7% was positive for Cryptosporidium, Infection was present in 0.3% fecal samples and also in 0.5% In the work of the authors, low rate of Cryptosporidium baileyi infection was detected, but in critical situations and our poor management circumstances, cryptosporidiosis occurs in serious feature especially in immune suppressed individuals.
