Risk factors associated with intestinal parasitic infections among children.

Intestinal parasites are endemic worldwide and have been described as constituting the greatest single worldwide cause of illness and disease. The effective prevention and control of intestinal parasitic infections requires identification of local risk factors, particularly among high-risk groups. This study retrospectively analyzed demographic factors that may affect the prevalence of intestinal parasites among school children.

Cockroaches and flies in mechanical transmission of medical important parasites in Khaldyia Village, El-Fayoum, Governorate, Egypt.

The role of non-blood sucking insects in dissemination of human parasites was investigated in Khaldyia Village, Al-Fayoum Governorate over during the summer of 2011. A total of 278 American cockroach (Periplaneta americana), and 508 house flies Musca domestica var. vicina were collected.

The role of insects in mechanical transmission of zoonotic human parasites.

Arthropods can be found on human or animals as ecto-parasites as well as endo-parasites. The ecto-parasites or vectors can contaminate stored foods and transmit illness, or introduced diseases in new area. Pet species facilitating infestations, and different risk factors related to infestation were identified.

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.

Efficacy of two plant extracts against vaginal trichomoniasis.

Trichomoniasis vaginalis is now an important worldwide health problem. Metronidazole has so far been used in treatment, but the metronidazole-resistant strains and unpleasant adverse effects have been developed. Treatment of patients with metronidazole refractory vaginal trichomoniasis constitutes a major therapeutic challenge and treatment options are extremely limited.

Parasitiosis in handicapped children in an Egyptian blind asylum.

Examination of visually handicapped children and their serving staff revealed in a descending order Enterobius vermicularis, Giardia lamblia, Entamoeba histolytica, Hymenolepis nana, Ascaris lumbricoides, Cryptospodium parvum, Tricocephalus trichura and Strongyloides stercoralis. Head lice were encountered. But, neither blood parasites nor protozoan infective agent in water for human consumption.

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.

Molluscicidal Activity of Some Solanum Species Extracts against the Snail Biomphalaria alexandrina.

Background. Snails' species are associated with transmission parasitic disease as intermediate host. Biological control stands to be a better alternative to the chemical controls aimed against snails.

Efficacy of ocular instillation of Fasciola hepatica crude adult antigen to diagnosis animal fascioliasis.

Locality prepared crude F. hepatica adult antigen for ocular instillation was evaluated in live sheep and buffaloes compared to stool examination and macroscopic examination of these animal after being slaughtered. Ocular instillation proved to be cheap, simple, time consuming, but could not replace stool examination, due to false positive cross reactions.

Zoonotic cryptosporidiosis in man and animal in farms, Giza Governorate, Egypt.

To demonstrated the zoonotic cryptosporidiosis. A total of 189 farmers and their farm animals (200= 71 buffaloes, 59 cows, 43 sheep and 27 goats were examined. Stool samples Each stool sample was subjected to the direct wet smear method and Sheather's sugar flotation and acid-ether sedimentation techniques and stained with four stains (Modified Ziehl Neelsen, Safranin, methylene blue, Aniline carbol methyl violet and Giemsa).

Hydatidosis granulosus in Egyptian slaughtered animals in the years 2000-2005.

Hydatidosis was investigated among camels, sheep, goats, and pigs in Egyptian official abattoirs, from August 2000 to August 2005, and among cows and buffaloes were in Mansoura official abattoirs, in the year 2005. One hundred randomly chosen animals of each species were subjected to serologic and histopathologic examinations for infections. The overall five years hydatidosis prevalence was 2.
