to investigate the prevalence of cryptosporidium infection in horses, a total of 221 faecal specimenswere collected from 18 villages of urmia, northwestern iran. the samples were studied microscopically bymodified ziehl-neelsen staining. the cryptosporidial infection was found in the collected samples from 11 of18 villages. although the prevalence of the infection was 15.8%, none of the infecte...

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...

Cryptosporidium spp. is a protozoal parasite that can cause significant gastrointestinal diseases in humans and animals. Those parasites infection, especially young immunosuppressed animals many mammals, poultry, reptiles, humans, Localised the digestive system, epithelial cells threaten human animal health with their zoonotic properties. The study's material consisted of 200 dogs different bre...

Background: Tuberculosis remains a major public health problem worldwide. Direct Ziehl Nelseen (ZN) is the conventional Laboratory method for diagnosis of TB. However, there are higher chances missing TB positive cases due to insufficient sensitivity. This would eventually lead transmission and hence mortality. Objective: To determine sensitivity specificity ZN diagnostic technique on concentra...

1,001 faecal samples were obtained from 89 sheep (lambs and adult), 184 goats, 190 horses, 178 rabbits, 110 camels, 200 broiler chicken and 50 turkeys housed in farms from different localities in Tunisia. All samples were analysed for Cryptosporidium oocysts by microscopic examination of smears stained by modified Ziehl Neelsen technique. The parasite was detected in ten lambs and adult sheep (...

We report a case of Crohn's disease in a 32-year old Saudi male. The disease presented with severe, life-threatening ileal bleeding necessitating an urgent laparotomy and 100 cm of ileum and ascending colon was resected. The bleeding source was several ulcers in an inflamed ileum and histopathologic examination revealed typical findings of Crohn's disease with a chronic, transmural inflammation...

This report describes an elderly patient with urinary symptoms who showed surface colonisation of the transitional mucosa of the bladder by an unusual haematoxophilic microorganism superficially resembling the "blue fuzz" seen in colonic biopsies showing intestinal spirochaetosis. Special stains showed that the organisms were Gram and Giemsa positive, weakly argyrophilic, and Ziehl-Nielsen nega...
