Prevalence OF Anisakid Nematode larvae infecting some marine fishes from the libyan coast

This study examined eight hundred ninety six marine fishes belonging to nine different fish species; Synodus saurus; Merluccius merluccius; Trachurus mediterraneus; Serranus cabrilla; Mullus surmuletus; Diplodus annularis; Spicara maena; Siganus rirulatus and Liza ramada. The fishes were bought from fish markets at five different sites on Libyan coast, from January to December 2013, for study the anisakids larvae among them. The results showed that 344/896 fishes [38.4%] were infected with Anisakids larvae. S. saurus was the highly infected [80.9%], followed by T. mediterraneus [77.5%] but, S. cabrilla, S. maena, M. merluccius, M. surmuletus, and D. annularis were least anisakid infected showed rates of 58.2%, 53.8%, 43.7%, 36.7% and 3.6%, respectively. No parasites were in S. rirulatus and L, ramada. Ten species of Anisakids larvae was detected during the present study. Two Pseudoterranova sp. Larvae, two types of Anisakis larvae, Anisakis simplex larva and Anisakis sp. Larva, two types of Contracaecum sp. Larvae and four Hysterothylacium larvae. Females showed higher prevalence than males. The number of anisakid larvae varied according to body length and weight of infected fish, without significant difference between prevalence and seasons, but, a significant difference was between prevalence and regions

Ultrastructural study of host-parasite relationship and pathogenicity of Eimeria sp. infecting Libyan Jird [Meriones libycus] [lichtenstein, 1828]

The relationship of Eimeria sp. and its host fat LibyanJird [Meriones libycus] was studied on an ultrastructural level. The host cellular organelles [nucleus, mitochondria, endoplasmic reticulum and golgi apparatus] and the changes of its infected intestinal epithelial cells during the development of parasitic stages [schizogony and gamogony] were studied and compared with those non-infected cells. The ultrastructures of intravacuolar tubules and folds in the parasitophorous vacuole [P.V.] were described. These fine structures may involve in the transport-tation of materials from the host cell to across the parasitovorous vacuole [P.V.]

Prevalence of hydatid cysts in slaughtered animals in Sirte, Libya

The prevalence of cystic echinococcosis was studied among the livestock slaughtered in abattoir of Sirte, Libya during the period July 2004 to May 2005. The overall infection rate of 4.9% in sheep, 2.4% in goats, 2.7% in camels and 15% in cattle were observed. The increase in prevalence with age of the animals was statistically significant in the four species. In female goats, examined infection was higher in the male. Liver had higher hydatid cysts than lungs in sheep, goat while infected lungs had higher in camel

Prevalence of intestinal parasites among primary schollchildren in Derna district, Libya

The prevalence of intestinal parasites and some hygienic factors was evaluated in primary schoolchildren in Derna District. A total of 1039 stool specimens were examined by direct smear and formaline-ether concentration methods. The results showed that 31% of the children were infected with at least one or two parasites. These parasites were Giardia lamblia [12.7%], Blastocystis hominis [6.7%], Entamoeba histolytica/ Entamoeba dispar [6.6%], Entamoeba coli [3.2%], E. hartmanni [1.0%], Enterobius vermicularis [0.6%], Ascaris lumbricoides [0.1%] and Hymenolepis nana [0.1%]. A significant difference was between infection rate and parent's education [P= 0.000], socio-economic status of the family [P= 0.000], family size and number of rooms in houses [P=0.000]. Also, there was a significant differences between infection rate and source of water for human consumption [P=0.05]

Trichomoniasis among women with vaginal discharge in Benghazi City, Libya

From April 2000 to July 2001, clinical and wet-mount exami-nation were performed on 2450 women attending gynecologic department, EL-Keish Polyclinic, Benghazi City. The mean age was 34 +/- 7[inyears]. 328[13.4%] women were clinically diag-nosed as having viginatis. Sterile vaginal swab of the posterior fornix was stained by Giemsa and examined as wet smear for trichomoniasis infection. 29/2450, [1.2%] had T. vaginalis The infected women suffered vaginalis discharge [93.10%], burning [81.48%5], vulvar pruritis [79.39%], dyspareuria [40.47%], dysu-ria [21.43%] and strawberry appearance [75.86%]

biochemical study of cystic stage fluids of echinococcus granulosus of animal orign in Libya

The biochemical analyses of hydatid cyst fluids of sheep, goats and camels slaughtered in abattoir of Sirt, Libya showed the same constituents of elements and organic compounds. But, sheep hydatid cyst fluids contained significantly more triglycerides [p<0.05], phosphorus [p<0.05] and protein [p<0.001] than those in camels and goats. Urea was significantly more [p<0.05] in sheep and goats compared to camels

Hydatidosis in camels [cameus dromedarius] slaughtered at sirt abattoir, Libya

Fifty out of 1380 [3.62%] local bred camels [Camelus dromedarius] harboured hydatid cysts of Echinococcus granulosus. Prevalence in males was 3.07%, in females was 4.42% and overall prevalence rate was 3.62%. Infection was higher in age group 1 <3 years than others. The most commonly infected organs were lungs 46% followed by liver 24%, both liver and lungs constituted 30% of infection. Hydatid cysts of lungs had a higher fertility rate [85.77%] than those of liver [14.23%]. The mean number of cysts in infected liver was 1 to 15 and in infected lung were 1 to 17 cysts. Intensity of infection increased with increasing age. Cysts size varied from 1-8 cm in diameter

Hydatidosis echinococcosis in libya [review article]

Cystic echinococcosis due to Echinococcus granulosus is a serious public health and livestock economy problem in Libya. The present paper reviewed and summarized all data available on hydatidosis since 1970. In Libya, the disease was described as hyper-endemic [Matossian et al., 1977]. However, many reports used the term endemic [Dar and Taguri, 1979; Gebreel et al., 1983; Shaafie et al., 1999]. The term is more realistic as the incidence of the disease within the Libyan population was >1 per 100,000 [Shambesh, 1997] and rate of hydatidosis in sheep was about 12.7% [Gusbi et al., 1987]. The values did not fulfill WHO criteria to describe hyper-endemic [i.e. surgically >10 per 100,000 and 50% rate in sheep [Craig et al., 1991]
