Coccidiosis, caused by species of the apicomplexan parasite Eimeria, is a major disease of pigeons and to quails. Therefore, the present study was conducted to detect the prevalence and identify the species of Eimeria causing coccidiosis in both pigeons and quails in Qena province, Southern Egypt. In the current study, three hundred and sixty fecal samples of each species were collected and screened for Eimeria infection by floatation technique from November 2017 to October 2018.The results of the current study revealed an overall prevalence of 56%, with a higher infection rate in pigeon (58.3%) in comparison to quails (53.9%). Additionally, squabs had the highest prevalence (72.8%) as compared to adults (37.3), whereas the higher prevalence of Eimeria was observed in male birds in both species. Peak prevalence was observed in Autumn and Winter for pigeon and quails respectively. The results also, showed that more than one Eimeria species existed in most fecal samples, and the infection rate of identified Eimeria spp. in these samples was Eimeria labbeana (37.2%), E. columbae (30.8%), E. columbarum (27.9%) and E. gourai (4%) respectively.On the other hand, common Eimeria spp. found in quails were E. tsunoda (51.3%), E. uzura (28%)and E. bateri (20.5%).This indicates that Eimeriatsunoda are the predominant species in Qena Province. Histopathology also revealed a developmental stage of the parasite in the intestinal tract and desquamation of the epithelial lining with areas of necrosis. In conclusion, this study provides basic information on the first detection of coccidiosis of pigeons and quails in Qena Province, Egypt, which has an implication on the sustainable birds’ production for human protein requirement.

Parasites of fish are of concern since they often produce a weakening of the host`s immune system thereby increasing their susceptibility to the secondary infections, resulting in the nutritive devaluation of fish ,compete for food, depriving fish of essential nutrients, inhibiting growth leading to morbidity and mortality and subsequent economic losses. Few data has been reported to identify major parasite of fish in Qena Governorate, Egypt. Accordingly,the study aimed to estimate the prevalence of gastrointestinal parasite infecting fish. Afield study was conducted during the period from the beginning of January 2015 to the end of December 2016.A total of 144 Clarias gariepinus (Carmoot) fish samples were collected either alive from fishermen or fresh as possible from fish markets at Qena Governorate for parasitological studies. Parasite collected and prepared then identified under the microscope. Out of 144 examined fish 84 (58.3%) samples were infected with different gastrointestinal parasites. The obtained results found that the most frequent parasitic infection among examined fish was cstodes with an infection rate of (35.4%) ,followed by trematodes infection (27%), while the lowest infection rate, were recorded in nematodes infection(16.7%),Regarding to the seasonal prevalence of the recovered parasites, we concluded that the highest rate of parasite infection was observed during Spring season (83.3%), followed by Winter (66.7%), Summer recorded (50%) and Autumn season which represented the lowest rate of infection (33.3%). The most common species of cestodes were Monobothrium sp which recorded the highest infection rate (27.8%) and Polyonchobothrium clarias (5.6%), followed by trematode species Orientocreadium batrachoides (24.3%) and nematode species Paracamallanus cyathopharynx (10.4%) and Procamallanus laevionchus (5.6%).

The present study was carried out to make a spot light on nematode parasites infecting Freshwater fish at Qena Governorate; including prevalence, seasonal dynamics of infection; intensity and morphology of the recovered parasite species. It was found that the infection rate of different nematode among fresh-water fish in Qena Governorate was (13%). Lates niloticus has highest infection rate (27.8%) followed by Carias gariepinus (8.3%) the Oreochromis niloticus (2.3%). Concerning the seasonal prevalence Winter has highest infection rate followed by Autumn then Summer and Spring. Four nematodes were recovered and identified as Paracamallanus cyathopharynx (2.8%) in Clarias lazera; Procamallanus laevionchus (2.8%) in Clarias lazera; Contracaecum sp. (2.8%) in Oreochromis niloticus and Clarias lazera and (26.4%) in Lates niloticus and Dichelyne niloticus (4.2%) in Lates niloticus. The mean intensity of infection of Contracaecum sp. among Oreochromis niloticus., Clarias gariepinus and Lates niloticus was 2%, 22% and 20% respectively.

The present study describes the occurrence of various gastrointestinal helminths and liver flukes in goats from post mortem examinations performed between 2010 and 2011. Forty five adult goats were euthanized necropsy examination and for identification of adult gastrointestinal helminths and liver flukes. Eleven animals (24.44 %) were found to be infected with one or more species of gastrointestinal helminth. Haemonchus contortus emerged as the most prevalent species (15.5 %), with Moniezia expansa and Fasciola gigantica also being common (11.11 % and 4.4 %, respectively). Additionally, Haemonchus longistipes, Cysticercus tenuicollis, and Paramphistomum microbothrium were present at low infection rates (2.2 %). Mixed infections were similarly most prevalent. Haemonchus longistipes; the most pathogenic Strongyle nematode of camels was reported for the first time infecting goats in Egypt. The present study indicates that abattoir surveys would reveal the prevalence of various species of problematic helminths, and thus appropriate measures can be adopted to control the respective worms.

Three species of fish (Oreochromis niloticus, Clarias lazera and Lates niloticus) were collected from Qena, Upper Egypt during the period from April, 2012 to the end of March, 2013. Upon their inspection, of 6 of ectoparasites species were recovered 3 monogeneans (Cichlidogyrus arthracanthus, Euryhaliotrema lovejoyi and Dactylogyrus spp.), two crustaceans (Lamproglena monody and Ergasilus sarsi) and one protozoan (Henneguya assuiti). The overall prevalence of infection was 12.03% and the highest peak was observed in O. niloticus with 19.4% (14/72) and the lowest percent was recorded in L. niloticus with 5.6% (4/72). Also, seasonal dynamics among the examined fish were recorded.The study revealed the occurrence of one monogenean trematode; Euryhaliotrema lovejoyi for the first time in Upper Egypt.

This study was performed for the purpose of investigating the prevalence and the species composition of Sarcocystis spp. in buffaloes in Assiut province, Egypt. Macroscopically we reported the infection of buffaloes with Sarcocystis fusiformis, while microscopically three Sarcocystis species (Sarcocystis cruzi, Sarcocystis levinei and Sarcocystis hominis) cysts were recognized, and were differentiated by their morphological features using both histopathological sections and electron microscope scanning. Regarding the prevalence of Sarcocystis species among buffaloes in Assiut province, we reported that, using gross examination of 90 buffaloes’ esophagus, only 23 samples out of 90 (25.5 %) were found to be infected; on the other hand, by using microscopical examination, the prevalence was 27.7 % (25 samples out of 90 samples were found to be infected). Using ELISA, 85 samples out of 90 (94.4 %) were found positive, an overall prevalence of 94.4 %. In this work we concluded that customary meat inspection methods in abattoirs in Egypt are insufficient for detecting Sarcocystis infection. Due to the presence of hidden or microscopic cysts, we strongly recommend the use of combined microscopical examination and ELISA for Sarcocystis diagnosis, to avoid human infection of such zoonotic parasite and to control the consequent disease. In addition, this study introduced the first report of S. cruzi in buffaloes in Egypt, and proved the hypothesis that S. cruzi is able to use animals such as water buffalo as intermediate hosts.
