Out of ninety eight of camels (Camelus dormadarius) examined, only forty eight (48.9 %) were found to be infected with blood protozoan parasites (Trypanosoma evansi, Theileria sp. and Babesia sp.). The higher incidence of infection were found in males (36.7%) whereas, (12.24%) in females. Microscopical examination revealed that longitudinal binary fission, the stumpy, slender forms of Trypanosoma evansi, trophozoites of both Theileria sp. And Babesia sp. Experimental infection revealed that both of Babesia and Theileria have a zoonotic importance for their transmissible to the experimental animals.

Out of 195 Camelus dromedarius examined only 19 were infected (9.7 %) with this parasite. The life cycle of T. sp. involves many morphologically distinct stages-more than described for any other genus in the Trypanosomatidae. This parasite was appeared for the first time in Camelus dromedarius at Assiut, Egypt. Most of stages of T. dromedarius (n.sp.) which were appeared in the blood of Camelus dromedarius are amastigotes stages. At the same time spheromastigots, epimastigote stages and trypomastigote stages with two shapes slender and broad. In experimental infection, the trypanosome was found to be transmissible to laboratory white mice, also metacyclic and amstigote formes were seen.

Babesia and Theileria are intraerythrocytic parasites which are capable of infecting a wide range of vertebrates causing huge economic losses. Histopathological and hematological changes during Babesia and Theileria inoculation in rat they were reported. Objective of the study is to determine the presence of Babesia & Theileria infected Camelus dromedarius at Assiut locality, Upper Egypt and their effects on hematological and tissues (liver, lung and kidney) of rat by injection in the blood. Blood samples were collected from Camelus dromedarius from different localities of Slaughter houses at Assiut city, Egypt (Dairout, Beni ady and Elethamna). Thick and thin blood smears were made for morphological examination of some protozoan blood parasites with electron microscopic studies. Out of (195) one hundred and ninety five Camelus dromedarius were examined and only twelve (6.1 %) were infected with Th. assiutis (n. sp.) and fifty one were found to be infected (26.1 %) with B. Cameli (n. sp.). For the first time the parasites were infected camels at Assiut. These parasites were injected in the blood of rat and the changes occurred on the organs were seen. Also Hemoglobin concentration, WBCs, RBCs, hematocrite, MCV, MCH and MCHC were measured for detection the hematological effects of these parasites. This study has reported for the first time the presence of Th. assiutis (n. sp.) & B. Cameli (n. sp.). in Camelus dromedarius and the results can lead to the prevention of babesiosis and theileriosis in the region to increase the livestock output.

Abstract: The floristic diversity and vegetation–environment relations in the southern part of the Eastern Desert, between 26°45′N and 24°1′N and between 32°45′E and 35°00′E and covering a total area of about 54,500 km2, were investigated. For this purpose, 142 georeferenced stands distributed in four transects were selected: 22 from Qena-Safaga road (T1), 28 from Idfu-Marsa Alam road (T2), 46 from Aswan-Kharit-Gimal (T3), and 46 from Red Sea Coastal Plain (T4). Altogether, 94 species belonging to 33 families were recorded, and the species richness (SR) varied from one transect to another: 46, 35, 52, and 46 in T1, T2, T3, and T4, respectively. Soil samples were collected from each stand, and the soil texture, soil moisture content, organic matter (OM), electric conductivity (EC), total soluble salts (TSS), pH, and major ions (Na+, K+, Ca+2, Mg+2, Cl–, SO4 –2, and HCO3 –) were determined. The soil–vegetation relationships were assessed by both detrended correspondence analysis and canonical correspondence analysis. Both species diversity measurements (SR and H’) exhibited significant differences among the separated vegetation groups within each transect. Classification of the vegetation resulted in 6, 7, 4, and 6 vegetation groups for T1, T2, T3, and T4, respectively. Canonical correspondence analysis showed well the relative positions of species and sites along the most important ecological gradients. The segregation of these groups along the first two axes of the biplot demonstrated that soil texture, moisture content, salinity, sulfates, and organic matter contents were highly correlated with the distribution of species.
