On the presence of Sarcocystis miescheri sp. nov. in camels of Qena Governorate
It is the 1st 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.

Mosquitoes (Diptera: Culicidae) in El Gharbia Governorate, Egypt: their spatial distribution, abundance and factors affecting their breeding related to the situation of lymphatic filariasis
Mosquitoes were surveyed (March - May, and November 2007) in all centers of the El GharbiaGovernorate. Seven mosquito species (6 culicine and 1 anopheline) were collected. These are Culex pipiens, Cx. perexiguus, Cx. antennatus, Cx. theileri, Ochlerotatus detritus, Culiseta longiareolata and Anopheles tenebrosus. Cx. pipiens, the main filariasis vectorwas the most common or predominating species (ca. 45%, 15 adult/room and 86%, 63 larva/SU, P<0.01). Cx. antennatus (ca. 38%, 13 adult/room) was also common species (P<0.01). For the three common species, Cx, pipiens, Cx. perexiguus and Cx. antennatus the relation of their larval and adult indoor densities with the environmental factors (water temperature and pH; indoor- and outdoor- temperature and RH) were examined. No infection with Wuchereria bancrofti were found in 1493 blood sample examined. Only one Elephantiasis case was reported from El Santa center (1/ 196 examined sample).

The association among mosquito species in the northern part of Egypt
Data on the co-occurrence of the reported mosquito species in northern part of Egypt represented by three Nile Delta Governorates (El-Menoufia, El-Gharbia and El-Sharqiya) and El-Ismailia Governorate were analyzed to examine the interspecific association among them. Such association was measured on the basis of the presence-absence data and on relative numbers of mosquito larvae. In general, compiled data of all Governorates indicated that: (1) High degrees of associations among the common species, Cx. pipiens, Cx. perexiguus and Cx. antennatus (CAB= 0.76 - 0.87, I= 0.79 - 0.92), (2) Cs. longiareolata showed positive association with the three common species based on presence-absence data while on abundance data showed negative association which suggests interspecific competition and (3) the two uncommon species An. tenebrosus and An. multicolor showed complete association (CAB and I=1.00). This study concluded that the significant levels or degrees of association among mosquito larvae vary depending on their areas of distribution and abundance and that such significantly positive associations between each the three common species with other indicate that their breeding requirements are similar.

Mosquito breeding sources in Qalyubiya Governorate, Egypt
Water collections which may provide breeding habitats for mosquitoes in Qalyubiya Governorate were surveyed throughout the period from April 2009 to March 2011. Mosquito larvae were collected on monthly basis from 14 different breeding places in eight villages. A total of 1800 from 2821 sites (63.8%) were found positive for mosquitoes, including 312 canals, 271 pools, 191 unused wells, 166 rice fields, 142 irrigation channels, 130 ponds, 128 drainages, 115 catch basins, 85 irrigation basins, 82 ditches, 70 swamps, 66 temporary pools, 22 unused tires and 20 irrigation drainage tubes. Mosquito larvae were found in a variety of water collections including temporary, permanent, natural or man-made habitats. Permanent and semipermanent water collections were the main sites for mosquito breeding. Nine mosquito species were identified in the study area namely, Culex pipiens 64.7%, Culiseta longiareolata 13.5%, Cx. antennatus 8.8%, Aedes caspius 6.3%, Cx. vagans 2.5%, Cx. decens 1.9%, Cx. perexiguus 0.9%, Cx. univittatus 0.8% and Anopheles multicolor 0.6%. Simple and Multiple regression models showed that temperature, Ammonia and Nitrate were the best predictors for mosquito larval density (P = 0.0397), (P = 0.0241) and (P = 0.0040), respectively. The year-round presence of immature mosquitoes indicates that climatic conditions of the area are not limiting to the development of most prevailing mosquito species. Catch basins, unused wells and drainages are playing the major role in mosquito problem in Qalyubiya Governorate.
