Predominance of Cryptosporidium parvum genotype among diarrheic children from Egypt as an indicator for zoonotic transmission.

Cryptosporidium is a genus of zoonotic pathogens transmissible from a variety of animals to humans and is a considerable public health concern. It is a significant cause of diarrheal disease in developing and industrialized nations. Cryptosporidium parvum and Cryptosporidium hominis are the main agents of cryptosporidiosis in humans.

Metacercariae recovered from fresh-water fishes in the vicinity of Qualkyobia Governorate, Egypt.

A total of 410 Tilapia zillii, 70 Clarias gariepinus, 30 Bagrus bajad and 15 Chlrysichthys auratus fishes were collected from different water bodies in Qualyobia Governorate. Microscopic examination of samples showed infection in muscles and head region (gills & branchial cavity) with encysted metacercariae in 91.7% of T.

Effect of different temperatures on viability of seven encysted metacercariae recovered from freshwater fishes in Qualyobia, Egypt.

Encysted metacercariae (EMC) from seven trematod-zoonotic parasites were exposed to different temperature mechanisms. Boiling of the infected fishes was sufficient to kill the EMC, frying of fishes for five minutes was quite sufficient to inhibit the viability of EMC, but frying for 10 minutes killed all EMC. Grilling of infected Tilapia zillii was sufficient to kill EMC after 10 minutes; however five minutes were sufficient only to kill EMC in Clarias gariepinus.

Zoonotic cutaneous leishmaniasis: reservoir host and insect vector in north Sinai, Egypt.

Cutaneous leishmaniasis (ZCL) is a protozoan disease well documented not only in Egypt, but in nearly all the East Mediterranean Countries. Sinai Peninsula was a sparsely populated area where sporadic cases of ZCL were reported with the reconstruction of Sinai and people coming in and out, it was indicated to study the status of ZCL in North Sinai Governorate, the reservoir host(s) and insect vector(s) in Sinai. In the present study, the six species of rodents were trapped from areas or nearby areas where human ZCL cases were detected.

Re-evaluation of zoonotic cutaneous leishmaniasis status in North Sinai Governorate, Egypt.

Generally speaking, there are at least few endemic zoonotic cutaneous leishmaniasis (ZCL) in the Sinai and the Suez Canal Governorates. A spotlight survey for new cases of human ZCL among out-patients with skin complaints revealed sixteen out of 100 (16%) individuals examined. But, none ZCL infection was found among 50 normal individuals.
