coccidian protozoa of cyclospora cayetanensis are obligate intracellular apicomplexan parasites that infect the mucosal epithelium of the small intestine of immunocompetent and immunocompromised persons. a 25- years old woman from around, tehran with complaint of faintness and fatigue with hiv positive/aids confirmed eight months ago was admitted in imam khomeini hospital, tehran, iran in 2014....

A NEW SPECIES OF COCCIDIAN (PROTOZOA Apicomplexa: Eimeriidae) obtained from rheas, Rhea americana, is reported in Brazil. Oocysts of Isospora rheae sp. nov. are spherical to subspheroidal, measuring 22.6 × 21.0 µm, and have a double and smooth wall that is approximately 1.7 µm thick. The micropyle, oocyst residuum and polar granule are absent. Sporocysts are slightly ovoid, measuring 13.9 × 9.6...

Cyclospora and Cryptosporidium are obligate, intracellular, coccidian protozoa that cause selflimited diarrhoea in immunocompetent and prolonged diarrhoea in immunocompromised patients. This is the first case of coccidia infection acquired after swimming in a swimming pool in Nepal. This study describes the chronological evidence of these coccidia infections in a Nepalese swimmer with the possi...

BACKGROUND Majority of parasitic infections in rodents have zoonotic importance. This study aimed to determine the frequency and intensity of intestinal protozoa infections of rodents including Meriones persicus, Mus musculus and, Cricetulus migratorius. METHODS This survey was conducted in Meshkin Shahr district in northwestern Iran from Mar. to Dec. of 2014. Intestinal samples of 204 rodent...

Parasitic infection caused by helminths and protozoa are the major cause of human disease in most countries of tropical region. It is estimated that about 3.5 billion people are infected with intestinal parasites of whom 450 million are ill. The prevalence of intestinal parasitic infection varies not only geographically but also in different region in the same country. The present study is unde...

In the current study, a new coccidian species (Protozoa: Apicomplexa: Eimeriidae), collected from the rufous-browed peppershrike Cyclarhis gujanensis Gmelin, 1789, is reported from Brazil. Isospora pitiguari n. sp. has oocysts, which are spherical to sub-spherical, 26.8 × 25.7 μm, with smooth, bilayered wall ~1.5 μm thick. Micropyle, oocyst residuum, and polar granule are absent. Sporocysts are...
