Cryptosporidiosis is one of the main protozoan infections in birds. It manifests as either a respiratory or a digestive illness, and it affects a very large number of avian species across several continents. The aim of this review is to report on the main results of studies on cryptosporidiosis among birds and the importance of these results to veterinary medicine and public health.

Two cases of chronic giardiasis of the stomach diagnosed from gastric mucosal biopsy specimens are reported. The first case was associated with an acute-on-chronic gastritis and Helicobacter-like organisms, and the second with an adenocarcinoma of the stomach. In both cases the trophozoites had been missed in earlier biopsy specimens. As far as is known this is the first report of giardiasis of...

BACKGROUND In persons with acquired immunodeficiency syndrome (AIDS), Cryptosporidium parvum causes a prolonged, severe diarrheal illness to which there is no effective treatment, and the risk of developing cryptosporidiosis from drinking tap water in non-outbreak settings remains uncertain. To test the hypothesis that drinking tap water was associated with developing cryptosporidiosis, we cond...

To determine the prevalence of giardiasis in Gambian children with chronic diarrhoea and to assess their response to treatment, 31 children with chronic diarrhoea and malnutrition were investigated for giardiasis using a combination of serology (specific antigiardia IgM antibody) and microscopy of faeces and jejunal biopsy specimens. Fourteen of 31 children with chronic diarrhoea had giardiasis...

Giardia duodenalis is an intestinal parasite that causes giardiasis, a widespread human gastrointestinal disease. Treatment of giardiasis relies on a small arsenal of compounds that can suffer from limitations including side-effects, variable treatment efficacy and parasite drug resistance. Thus new anti-Giardia drug leads are required. The search for new compounds with anti-Giardia activity cu...

to investigate the prevalence of cryptosporidium infection in horses, a total of 200 fecal specimens were collected randomly from five farms in tehran. samples were taken during a year, 50 specimens each season. of these specimens, 57 were obtained from caspian pony. the presence of oocysts in the samples was confirmed by modified ziehl-neelsen staining of direct smears of the fecal material fr...

giardia is a flagellate protozoan with worldwide distribution that causes significant gastrointestinal diseases. the life cycle of the organism alternates between the active, proliferating trophozoite and the dormant cyst. 5-nitroimida-zoles have been used extensively in the treatment of amoebiasis, giardiasis, and trichomoniasis. we have previously synthesized some new analogues of metronidazo...
