Infestation status of Aega psora [Linnaeus, 1758] [Isopoda, Cymo-thoidae] skin parasite of the marine fish, Sardine [Sardinella gibbosa] of Port Said Mediterranean Coastal Zone, Egypt

An isopod parasite of family Aegidea was collected from marine fish, Sardinella gibbosa [new hosts] over 2-years period from 2007 to 2008. The fish hosts were captured in the coastal waters of Port Said, Egypt. The Cymothoa sp. and Aega sp. were only collected from skin of the new host, Sardinella gibbosa, and described on the basis of female specimens. The morphological characteristics of were discussed in details. Comparing the present specimens with the previously reported Aega sp. showed that the present material belongs to the type species of the genus: Aega psora [Linnaeus, 1758]. Monthly and seasonal patterns in infestation rates [N==593, W +/- SD [range] =50.09 +/- 3.8 g]. Parasitic specificity and prevalence are given Mean prevalence, P = 24 +/- 5.5 and mean intensity, MI +/- SD =28.44 +/- 16.19 and total number of infestation were estimated 59[10.35]

Levels of helminthic infections in the quails coturnix coturnix from kingdom of Saudi Arabia

The present study aims to clarify the difference of the intensity of parasitic infection between the domestic quails Coturnis coturnis and the migrant ones. A total of 60 domesticated and 60 migratory quails were investigated during the migration season September-November 2009 for intestinal parasites. Investigations revealed that both domestic and migrant quails were susceptible to infection with three helminth parasites; a nematode [Heterakis gallinaruni], and two cestodes [Choanotae-nia infundibulum and Hymenolepis sp.]. The prevalence of infection in the migratory males was higher than the female ones, the opposite results was obtained for the domestic birds. The differences in the prevalence were found to be statistically significant in case of the domestic birds. Single infection showed the highest prevalence followed by the double infection and finally the triple infection. The mean intensity of infection in the female domestic and migrant C. coturnix was higher than male

Parasitological studies of the lizard, ludakia stellio in arish, north Sinai governorate, Egypt

In the lizard, Laudakia stellio, the gastrointestinal tract harboured four helminthic-parasites: two nematodes Spauligodon auziensis [Seurate, 1917] Paraparyngodon hulbosus [Linstow, 1 897], two larval stages of nematode, and one cestode, Oochoristica sp. [Kennedy et al., 1982]. The total infection rate of L. stellio was 93%. Out of 45 L. stellio examined, 42 were infected with number of parasites ranged from 0-72 and mean intensity 11.57. Parasites burden on their host populations was highly aggregated with k value was 0.01. No significant correlation was found between host weight and intensity of infection. The histopathological impact of infection was examined indicating the tissue reaction against the parasite at the site of attachment
