BACKGROUND Cystoisosporiasis is an opportunistic infection seen more commonly in patients with acquired immunodeficiency syndrome. Although uncommon, Cystoisospora infection can occur in immunocompetent individuals but tend to be benign and self-limiting. Chronic infection however, has been described but diagnosis can often be challenging and requires a high clinical index of suspicion. CASE ...

Isospora (Cystoisospora) belli diarrhea can sometimes be fulminant in immunocompromised patients. It is endemic in tropical and subtropical areas, and sporadic episodes have been reported in nonendemic areas in nursing homes, day-care centers, and psychiatric institutions. We describe isosporiasis in an HIV-negative Sudanese-American female who presented with a debilitating diarrheal illness an...

N sweetclover (Melilotus alba Desr.) the allelic pair designated B/b was I originally thought to be concerned with coumarin biosynthesis. Extracts of BB plants were reported to contain substantial amounts of both free and bound coumarin, while extracts of bb plants contained only bound coumarin (GOPLEN. GREENSHIELDS and BAENZIGER 1957; HASKINS and GORZ 1957), more recently identified as coumari...

BACKGROUND Cryptosporidium and Isospora are known as one of the main cause of diarrhea in both immunocompetent and immunocompromised subjects, all over the world. Incidence of enteropathogens such as Cryptosporidium spp. and Isospora belli considerably has increased, since immunodeficiency virus (HIV) rapidly disseminated. In addition, cancer patients are highly susceptible to opportunistic inf...

To investigate the extent of genetic heterogeneity in the genus Isospora infecting patients in Thailand, a total of 38 fecal samples containing Isospora oocysts from human immunodeficiency virus/acquired immunodeficiency syndrome patients (n = 30), corticosteroid-treated patients (n = 3) and immunocompetent individuals (n = 5) were recruited for analysis. Remarkable variation in the maximum wid...

Coccidial parasites of the genus Isospora cause intestinal disease in several mammalian host species. These protozoal parasites have asexual and sexual stages within intestinal cells of their hosts and produce an environmentally resistant cyst stage, the oocyst. Infections are acquired by the ingestion of infective (sporulated) oocysts in contaminated food or water. Some species of mammalian Is...

BACKGROUND Cryptosporidium spp and I. belli are intestinal opportunistic infections associated with HIV/AIDS. A decline in the incidence of these opportunistic infections due to HAART was reported. We aim to investigate these parasites among HAART naïve and experienced HIV patients in south Ethiopia. METHODS A cross sectional study was carried out among 268 HIV- positive patients between Janu...

The horned dinosaur from the late Campanian Dinosaur Park Chasmosaurus Formation of Alberta, is known from numerous skulls and skeletons, but over a century after its description, the taxonomy of the genus is controversial. Two species, and , are currently recognized, with a Chasmosaurus belli C. russelli third species, , recently placed in a new genus, . C. irvinensis Vagaceratops Here, the Ya...

BACKGROUND Exogenous pretreatment of oxidative stress on callus cultures of Bellis perennis L. (common daisy) induced catalase (CAT), superoxide dismutase (SOD), total phenolic, total flavonoid, total protein and selected commercial phenolic compounds production and accumulation. MATERIALS AND METHODS The callus culture obtained from B. perennis pedicel explants was incubated on Murashige and...
