Abstract Background Enterocytozoon bieneusi , a microsporidian species, is zoonotic pathogen found in both humans and animals. Here, we determined the prevalence, explored different genotypes of E. wild rhesus macaques ( Macaca mulatta ) (Hainan Island China), assessed their potential. Methods We collected 173 fecal specimens from living Nanwan Monkey Island, Hainan, China. Subsequently, identi...

AIMS To detect intestinal microsporidiosis in paraffin wax embedded biopsy specimens using a fluorescence technique incorporating optical brighteners. METHODS Eight HIV infected patients with confirmed intestinal microsporidiosis (six with Enterocytozoon bieneusi, one with Encephalitozoon intestinalis and one with Encephalitozoon cuniculi infection) and 10 without infection were studied. Tiss...

Among the micro-organisms that may affect the respiratory apparatus are the protozoa. The diseases they may give rise to constitute a relatively uncommon group of respiratory ailments with, in the majority of cases, an underlying clinical situation corresponding to states of suppressed immunity (AIDS, transplants, malign haemopathies, corticotherapy, etc.). Other factors, such as visits to ende...

Human microsporidian infections have emerged following the onset of the AIDS pandemic. Microsporidia are unicellular eukaryotic parasites that form spores. They are an exceptionally diverse group of parasites that infect a wide range of eukaryotic cells in numerous invertebrate and vertebrate hosts. Of the 14 species newly described as pathogens in human, Enterocytozoon bieneusi, which causes g...

We have developed a new micromethod to study the effect of drugs on microsporidia, using MRC5 fibroblasts infected by 10(5) spores of Encephalitozoon cuniculi. After 3 days of incubation with various concentrations of drugs, parasitic foci were counted in stained cultures. The inhibition of microsporidial growth exceeding 90% with albendazole (0.005 microgram/ml), fumagillin (0.001 microgram/ml...
