Larval cestodes infecting commercial fish of Alexandria coast along the Mediterranean Sea: morphology and phylogeny.

Members of the order Trypanorhyncha are cestode parasites that are frequently found infecting the muscles of several marine fish species, affecting fish health and resulting in consumers' rejection. Seventy-five specimens of marine fish were freshly caught from boat landing sites at the Alexandria coast along the Mediterranean Sea in Egypt, including two Carangids, the greater amberjack Seriola dumerili and the gulley jack Pseudocarans dentex; two Serranids, the Haifa grouper Epinephelus haifensis and the mottled grouper Mycteroperca rubra. Forty-five fish were infected; the infection was recorded as blastocysts embedded in fish flesh.

Molecular evidence and morphological aspects of and re-description of (Digenea) from the Red Sea.

During a recent survey on digenean parasites infecting marine fish captured from water located along the Red Sea off Gizan Coasts, Saudi Arabia, thirty-two (29.09%) out of 110 fish were naturally infected with three different species of digenean parasites. The taxonomical status of the recovered worms was confirmed by light microscopy and molecular analysis.

The oil of garlic, Allium sativum L. (Amaryllidaceae), as a potential protectant against Anisakis spp. Type II (L3) (Nematoda) infection in Wistar rats.

The consumption of inadequately thermally treated fish is a public health risk due to the possible propagation of Anisakis larvae. The present study demonstrated the physiological and histopathological changes that accompanied an oral inoculation of crude extracts from fresh and thermally treated Anisakis Type II (L3) in rats. Worms were isolated from a marine fish and examined and identified using light and scanning electron microscopy.

Morphology and molecular taxonomy of the tongue worm, genus Raillietiella (Pentastomida) from the lungs of berber skinks Eumeces schneideri (Scincidae): First report.

In the present study, pentastomids belonging to the order Cephalobaenida were isolated from the lungs of Berber skinks Eumeces schneideri (Famiy: Scincidae), which were morphologically described by light and scanning electron microscopy and taxonomically justified by 18s rDNA molecular analyses of the parasites. Seventeen host specimens were collected from well-vegetated wadis at high altitudes, Jizan, Saudi Arabia as new type locality; twelve specimens (70.59%) were infected.

TH1/TH2 chemokines/cytokines profile in rats treated with tetanus toxoid and .

Natural products, including their purified materials, play a remarkable role in drug development. The Euphorbiaceae family, mainly , is used in some traditional medicine, and has evidence that its latex comprises immunomodulatory properties and cytokine production. This study aimed to measure the production of chemokines (IL-1α, IL-1β, IL-12, and RANTES), T1 cytokines (IFN-γ, TNF-α, GM-CSF, and IL-2) and T2 cytokines (IL-4, IL-6, IL-10, and IL-13) in rats after treatments with ethanol latex extract of .

Murray (1931) (Monogenea: Polyopisthocotylea), a Microcotylid Infecting the Gills of the Gilt-head Sea Bream (Sparidae) from the Red Sea: Morphology and Phylogeny.

Introduction: Monogenea is a class of ectoparasitic flatworms on the skin, gills, or fins of fish. Microcotylidae is a family of polyopisthocotylean monogeneans parasitising only marine fishes. This work describes and taxonomically determines a microcotylid polyopisthocotylean monogenean in an important fish in Saudi aquaculture.

Taxonomic Justification of the Pathogenic Strongylid Infecting the Arabian Camel as by Morphological and Molecular Phylogeny.

Introduction: There is still lack of morphological and phylogenetic information on the pathogenic nematode of the camel . In the present study, this parasite was isolated in Saudi Arabia and described.

Material And Methods: The abomasa of two Arabian camels were collected from a slaughterhouse in Abha province and examined for nematode infection.

DNA vaccination using recombinant Schistosoma mansoni fatty acid binding protein (smFABP) gene.

Schistosomiasis is a fatal disease that has a negative impact on health and economics. Praziquantel (PZQ) is the drug of choice for schistosomiasis treatment, but it has no prophylactic effect; therefore, vaccination is an essential requirement in schistosomiasis control. This work was carried out to investigate the possible effect of DNA vaccination against Schistosoma mansoni infection using recombinant S.

Light microscopy and surface topography of Urotrema scabridum and Renschetrema indicum (Digenea) from Rhinopoma hardwickii (Chiroptera): first report in Egypt.

This report introduced the description of two different species of digenean parasites isolated from the intestine of Rhinopoma hardwickii with new host and locality records in Egypt. The recovered helminthes were studied morphologically and morphometrically by light microscopy and the surface topography of the two species was elucidated by scanning electron microscopy (SEM). Urotrema scabridum had an elongated body, testes were tandem, ovaries were pretesticular, and vitelline follicles were observed in 2 lateral fields.

Comparative sequence analysis of domain I of Plasmodium falciparum apical membrane antigen 1 from Saudi Arabia and worldwide isolates.

The apical membrane antigen 1 of Plasmodium falciparum (PfAMA1) plays a crucial role in erythrocyte invasion and is a target of protective antibodies. Although domain I of PfAMA1 has been considered a promising vaccine component, extensive sequence diversity in this domain could compromise an effective vaccine design. To explore the extent of sequence diversity in domain I of PfAMA1, P.

Seroprevalence and risk factors of Toxoplasma gondii infection among pregnant women in south western, Saudi Arabia.

This study aimed to determine the seroprevalence of Toxoplasma gondii in pregnant women in the south western region of Saudi Arabia and to find out the possible risk factors that may lead to infection. This cross sectional hospital based study was carried out at three hospitals in the south western region of Saudi Arabia from January 2008 to August 2010. Blood samples from 487 pregnant women were collected and used to detect anti-T.

Effects of Schistosoma mansoni experimental infection on some inorganic elements in the snail host Biomphalaria alexandrina.

The alteration in the concentrations of metallic ion Pb, Zn, K, Na, Co, Fe, and Cu in the soft parts of the Biomphalaria alexandrina snails shedding Schistosoma mansoni cercariae was detected by flame atomic absorption spectrometry. Six elements Pb, Zn, K, Na, Co, and Cu were found to be present at significantly higher concentrations in cercariae-shedding snails compared with uninfected snails. The concentration of Fe ion showed non-significant decrease in the tissues of cercariae-shedding snails.
