Its transmission to herbivores animals led to a substantial economic loss in the meat productivity and reduced its quality. The increase of acquisition of dogs at homes nowadays led to an increase in the risk of infection with many parasitic diseases such as hydatid cyst disease. The present study was conducted to provide a modern view on the current status of hydatid cyst disease among slaughtered animals in Jeddah through periodic visiting to a slaughter house in North Jeddah. The mice prepared have been infected in the peritoneal membrane with 0.2 ml of hydatid cyst fluid containing ±2000 protoscoleces from fertile cysts obtained from an infected goat’s liver which resulted in a 75% infection rate. Mice infected with hydatid fluid from fertile cysts obtained from an infected camel’s lungs showed a result of 11.1% infection rate. The cysts appeared in the peritoneal and abdominal cavity.展开更多

Collected parasites were identified as, Isopoda (praniza larva of Gnathia sp.), Copepoda (Hatschekia sp.) Monogenea (Diplectanum sp.) and Digenea (Lecithoclaster and Bucephalus spp). Out of 30 specimens of fish caught from Jeddah coast 13 (43.4%) were infested by 90 parasites comprising of two parasite species, praniza larva and Hatschekia sp., with prevalence of infestation 40% and 3.33%, and mean intensity 7 and 6 parasites per fish respectively. 19 (63.3%) of Scarus fish caught from Rabigh coast were infested by 205 parasites representing 4 parasite spp. Diplectanum sp. represents the most commonly encountered parasite with prevalence (53.3%) and mean intensity (10.94%), followed by (Lecithoclaster sp. then praniza larva, prevalances (16.66% and 13.3%) and mean inentisities (3.4. and 1.75) respectively. Bucephalus sp. showed the minor, prevalence (3.33%) and mean intensity (6). Generally Scarus fish species from Rabigh had higher prevalence and mean intensity (63.3% and 7.59%) than Scarus fish species from Jeddah (43.4% and 6.92%). Female fish from Jeddah showed no parasitic infestation, while males were infested (prevalence 65% and mean intensity 6.92). Female fish from Rabigh had higher prevalence (84.21) and lower intensity (6.43) than males which showed prevalence (27.27%) and intensity (19). Relationship between parasitic infestation and fish species and sex were also studied in the two different localities and discussed.展开更多
