It is the 1 st time to study sarcocysts of camels in Qena Governorate, 156 specimens of camels (Camelus dromedarius) were collected from different slaughtered-houses in Qena Governorate, the rate of infection with Sarcocystis was (42.3 %). Out of 126 males, 54 (42.85 %) were infected while the infected number of females were 12 (40 %) from 30 specimens. Morphological and ultrastructures of muscle stage (sarcocyst) have been reported and illustrated in this study by both light and electron microscope, TEM showed that there are two types of Sarcocystis in camels in Qena Governorate. Dogs that infected with camel's oesophagus muscles contain mature Sarcocystis excreated two different types of oocysts in their feaces after 13-15 days of infection. Detailed description of oocysts has been reported.

Cattle are intermediate hosts for several species with different definitive hosts. The present study, to our knowledge, is the first to determine the prevalence of infection and morphologically and molecularly identify species in cattle in Qena Governorate, Upper Egypt. The samples were collected from the heart and oesophagus muscles of 84 slaughtered cattle (76 males and 8 females) aged between 11 months and 3 years from slaughterhouses in different localities in Qena Governorate, Upper Egypt. The samples were macroscopically and histologically examined, and the molecular identification of the species was performed using 18S ribosomal subunit DNA through PCR and DNA sequencing. Infection was detected in 72 out of 84 animals (85.7%) and was more prevalent in males (76.2%) than in females (9.5). Using light microscopy, the microscopic sarcocysts were observed to be thin-walled. Sequencing and genotyping revealed one isolate that had 99 and 100% identity, respectively, to, while another isolate had 95 and 99% identity to . The present study is the first to identify infection in cattle in Qena Governorate, Upper Egypt both morphologically and molecularly. and species were isolated from cattle, which is of veterinary importance and indicates that morphologically similar species are genetically distinct. Additionally, the results show that species are not host-specific.

Freshwater fishes were sampled from the River Nile at different localities in Qena Governorate (Qus, Qift, Dandara, El-Trammsa, El-Maana, Dishna and Nag-Hammady). The investigated fishes are Oreochromis niloticus (180) and Tilapia zilli (66). Out of 246 fishes examined, 61 (24.8%) were found to be infected with myxosporean parasites. The infection rate was 25% of O. niloticus and 24.2% of T. zilli. Eight species of Myxobolus spp. were described from gills and one species was found in blood. The collected parasites are M. agolus, M. heterosporus (type 2), M. clarri, M. heterosporus (type 3) and a myxosporean species had been found infecting gill filaments of O. niloticus. Meanwhile, blood of one O. niloticus fish was found harboring Myxobolus sp.I. M. tilapiae, M. niloticus, M. zilli and M. fahmii were found parasitizing gill filaments of T. zilli. M. heterosporus (type 2) had been studied using scanning electron microscope. Comparisons with closely related species are provided.

It is so for the first time to do general survey of protozoan parasites that infect freshwater fishes in Qena Province. The total number of fishes examined were 581 belonging to 10 families represented by 14 Species during the period from January 2006 to May 2008. Three species of Henneguya were recorded from two species of fishes. The first species is suggested to be a new one called Henneguya mandouri sp.nov. The second species is Henneguya assuiti,

Journal of Medical Entomology and Parasitology is one of the series issued quarterly by the Egyptian Academic Journal of Biological Sciences. It is an important specialist journal covering the latest advances in that subject. It publishes original research and review papers on all aspects of basic and applied medical entomology, parasitology and host-parasite relationships, including the latest discoveries in parasite biochemistry, molecular biology, genetics, ecology and epidemiology in the content of the biological, medical entomology and veterinary sciences. In addition to that, the journal promotes research on the impact of living organisms on their environment with emphasis on subjects such a resource, depletion, pollution, biodiversity, ecosystem…..etc. www.eajbs.eg.net Provided for non-commercial research and education use.
