background: microsporidia species are obligatory intracellular agents that can in­fect all major animal groups including mammals, birds, fishes and insects. whereas world­wide human infection reports are increasing, the cognition of sources of infec­tion particularly zoonotic transmission could be helpful. we aimed to detect zoono­tic microsporidia spore in fecal samples from some animals with ...

Human-associated microsporidia were frequently observed in fecal samples of 331 feral pigeons in Amsterdam, The Netherlands, obtained during high- and low-breeding periods. Thirty-six of 331 samples (11%) contained the human pathogens Enterocytozoon bieneusi (n = 18), Encephalitozoon hellem (n = 11), Encephalitozoon cuniculi (n = 6), and Encephalitozoon intestinalis (n = 1); 5 samples contained...

Encephalitozoon species are strict intracellular microsporidia. Cocultures with eukaryotic cell lines can become accidently contaminated by mycoplasmas. We propose a decontamination protocol based on differential cell targeting after intraperitoneal inoculation in mice. Mycoplasma-free microsporidia were isolated from the brains and spleens of inoculated mice 24 h postinoculation by using the c...

G A A b st ra ct s disease with hepatocellular carcinoma (HCC). Microsporidial infection was positive on wet preparation in 8(2.7%), in 11(3.7%) on Trichrome staining and in 13(4.3%) on PCR. Microsporidia was diagnosed with PCR in 8(61%) (p= 0.002) with IBS-D, 4(31%) with HCC and 1(8%) with functional dyspepsia. Conclusion: Microsporidial infection may be associated with IBS-D. PCR for microspo...

Therapy for microsporidia, which cause diarrhea and a wasting syndrome in persons with AIDS, has had limited success. Fumagillin, a naturally secreted water-insoluble antibiotic, has in vitro activity against microsporidia and has been used successfully in the treatment of superficial keratitis in patients with AIDS, but systemic therapy has been limited by toxicity of the currently available f...

A new species of Microsporidia classified to a new genus was observed in the trunk muscle of commercial hake (Merluccius capensis/paradoxus complex) from Namibian fisheries. Macroscopic examination revealed thin and dark filaments inserted among muscle fibers. Inside the filaments were many sporophorous vesicles with about 30-50 spores per vesicle. The shape of the spore was pyriform and the ex...

Microsporidia are eukaryotic organisms that cause zoonosis and are major opportunistic pathogens in HIV-positive patients. However, there is increasing evidence that these organisms can also cause gastrointestinal and ocular infections in immunocompetent individuals. In Korea, there have been no reports on human infections with microsporidia to date. In the present study, we used real-time PCR ...

PURPOSE The purpose of this study is to report a case of microsporidial endophthalmitis after penetrating keratoplasty in a healthy patient and discuss the management. METHODS This is a case report. RESULTS A 69-year-old healthy male underwent penetrating keratoplasty for corneal scar secondary to herpes stromal keratitis. He presented with features of acute graft rejection 3 years later. A...
