Abstract

The present work aimed to investigate the prevalence of zoonotic parasites in wild and cultured fresh water fish in El-Menia Governorate, Egypt. A total of 200 fish samples (100 wild and 100 cultured) included50 for each; Tilapia nilotica (Oreochromis niloticus), catfish (Clarias gariepinus), bajad (Bagrus bajad) and carp fish (Cyprinus carpio) were randomly collected from markets and some fish farms from El-menia city. Out of 200 examined fish 187 samples were infested by one or more zoonotic parasites with prevalence of 93.5%, highest infestation rate was detected in wild Nile fish 100 % in compared to 87 % in farmed one. The total prevalence of EMC among examined fish was 89.5%, it was 88% and 85% in wild fish and farmed fish, respectively. Microscopic EMC was detected in 83% and 73% of wild fish and farmed fish, respectively, while macroscopic EMC was detected in 5% and 12%of farmed fish and wild fish, respectively. Microscopic E.M.C. was identified as: Cynodiplostomum E.M.C and Prohemistomum E.M.C while, macroscopic E.M.C identified as Clinostomum phalacrocoracis. On the other hand, the total prevalence of Ichanthochephala among examined fish was 8 %, it was 13 % and 3 % in wild fish and farmed respectively, while the total prevalence of Cryptospordium spp and Capillaria spp. among examined fish was 39%, and 14.5 %, respectively.

The current study revealed variable prevalence of different zoonotic parasites in different species of examined fish, which represents a potential risk to public health if consumed raw or improperly cooked..
