Abstract | ||||
Cryptosporidium is a widespread pathogen that affects a wideranging of vertebrate hosts including humans, in which it is one of the main causes of diarrhea . Marine and fresh water fishes also harbor Cryptosporidium species. Relatively little is known about the epidemiology and taxonomy of Cryptosporidium in fish. In the current study three hundreds and ten fishes were collected from Mediteranean sea as a group one representing wild marine fish (n=130) and River Nile as a group two representing wild fresh water fish (n=180). Intestinal smears were stained by modified Ziehl–Neelsen stain then microscopically examined using objective lenses 10x, 40x and 100x. the infection rate was 25.48% , Cryptosporidium recorded higher prevalence in wild fresh water fish (30.5%) than wild marine water fish (18.46%), with significant difference (P=0.0159). In wild marine fish Cryptosporidium infection was higher in Sea bass (Dicentrarchus labrax) (22.8%) than Sea bream ((Sparus aurata) (13.33%),which doesnot show any significance (P=0.1629) . On the other side for fresh water fish the infection was higher in Tilapia nilotica (38.8%) than Mugil cephalus (22.2%), with significant difference (P=0.0152) . The present study provide the first assessed data on the prevalence of Cryptosporidium spp in wild marine and fresh water fish in Egypt. with future prospective to detect genetic characterization and zoonotic relationship of different Cryptosporidium genotypes in different type of fish. | ||||
