Molecular assay and in vitro culture for Blastocystis prevalence in Dakahlia governorate, Egypt.

Blastocystis is a polymorphic enteric parasite with a worldwide distribution. It is one of the most common human intestinal protozoans in developing countries. The primary objective of this study was to determine the diagnostic value of microscopy, stool culture, and a polymerase chain reaction (PCR) technique for assessment of Blastocystis prevalence and risk factors.

Conjugated silver nanoparticles as a diagnostic tool for circulating hydatid antigens.

Cystic hydatid disease is one of the most significant worldwide zoonotic diseases. The causative agent is the larval stage of Echinococcus granulosus. The diagnosis of cystic echinococcosis by clinical symptoms and scanning alone is often difficult and confusing.

External and intestinal parasites of pet dogs with reference to zoonotic toxocariasis.

Examination of 3000 pet dogs over two years at the Veterinary Teaching Hospital, Faculty of Veterinary Medicine revealed external and internal parasites. The external parasites were Rhipicephalus sanguineus, Ctenocephalus felis, Sarcoptes canis, and Sarcoptes scabiei. The internal parasites were Echinococcus granulosus, Dipylidium caninum, rare Heterophyes heterophyes, and Toxocara canis.

Biochemical parameters in chronic fascioliasis.

Serum lipids, liver enzymes and total bile acids were measured in chronic Fasciola (cholestatic and non-cholestatic) patients. Variations in the biochemical parameters between infected and control groups were detected and typified by considerably higher serum triglycerides (TG, P < 0.001), alkaline phosphatase (ALP, P< 0.

New concept of schistosomiasis lesions of urinary bladder versus development of bladder cancer.

Schistosomiasis haematobium precancerous lesions of urinary bladder included group 1: preneo-plastic non papillary (flat) lesions [reactive atypia, flat hyperplasia, keratinizing squamous metaplasia, glandular metaplasia, dysplasia, carcinoma in-situ (CIS)] and group 2 preneoplastic papillary lesions (typical papillary hyperplasia, atypical papillary hyperplasia, papilloma). The present work studied the content of the schistosomiasis precancerous lesions of the urinary bladder using image analyzer, thereby shedding more light on the significance on the early diagnosis of the high risky group. A total of 140 previously diagnosed schistosomiasis urinary bladder lesions (124 precancerous and 16 cancers as controls) were stained by H & E, and Feulgen stain.

Kinetics of eosinophilia and IgE production in experimental murine toxocariasis.

Eosinophilia and immunoglobulin E (IgE) antibody are considered the first and important elements in host responses to helminth infection. Toxocara canis, which elicits prominent eosinophilia and IgE production in normal mice, may be useful in understanding the kinetics of circulating peripheral blood eosinophils and IgE antibody during infection. The onset, magnitude and duration of peripheral blood eosinophilia and total IgE production after primary T.

Mirazid alone or combined with Paromomycin in treating cryptosporidiosis parvum in immunocompetent hospitalized patients.

Sixty cryptosporidiosis patients from Mansoura University Hospitals, 36 males and 24 females, with age from few months to ten years (mean age 6.1) were divided into three cross-matched groups of 20 patients each. All patients received the glutamine-based oral rehydration solution with 111 mmol/l glutamine, 20 mg zinc acetate once a day and vitamin A supplementation (200,000 IU) once a day for 2 weeks.

Phylogenetic evidence for recombination in SAG5 locus in Toxoplasma gondii.

The present study evaluated the hypothesis that genetic diversity in SAG5 genes was generated by recombination events. Three lines of evidence suggested that recombination occurred in SAG5 genes in T. gondii.

Natural infection of fresh and brackish water fish with heterophyid encysted metacercariae in Dakahlia Governorate, Egypt.

The encysted metacercariae (EMC) of heterophyids in the fish species; Mugil caphalus, M. capito, M. auratus, Oreochromis n.

Q fever (Coxiella burnetii) among man and farm animals in North Sinai, Egypt.

Antibodies against Coxiella burnetii were estimated among sheep, goats and camels (190), their owners (150 patients with pyrexia of unknown origin) and 30 normal individuals in North Sinai over the 2006 by indirect immounofluorescence assay. Nested polymerase chain reaction was used to detect Com-1 gene (genetic target of C. burnetii) encoding a 27-kDa outer membrane protein in the samples.
