Isospora belli, like Cryptosporidium sp., a sporozoan parasite of the small intestine, has been isolated from both immunodeficient and immunologically normal persons. In immunocompetent persons the infection may be asymptomatic; it frequently causes mild and self-limited diarrhea. The spectrum of the disease in persons with acquired immune deficiency syndrome is not well established. I. belli d...

Sir,?I read with interest the communication of Capt. Mukherji on ' The incidence of coccidiosis in the Arakans ' in 3'our December 1947 issue. I came across several (about a dozen) instances of isospora infection during routine stool examinations in army laboratories (1943-46). Most of these were ' routines' from the hospital patients (unselected), two detected during ' Food handler's carrier's...

Faecal samples from a couple of bare-throated bellbirds Procnias nudicollis imported from Brazil to Barcelona Zoo contained oocysts of Isospora araponga n. sp. Sporulated oocysts were subspherical to broadly ellipsoidal, 19.5 (17-22) x 15.5 (14-16.5) microm, shape index (length:width ratio) 1.26 (1.13-1.38) with smooth and colourless bilayered wall, about 1 microm thick, and with varying number...

Protozoa are among the most important pathogens that can cause infection in immunocompromised patients. They infect particularly individuals with impaired cell immunity, such as those with hematologic neoplasias, those submitted to transplant of solid organs, those under high-dose corticosteroid therapy, and carriers of the human immunodeficiency virus. Among the protozoa that most commonly cau...

Isospora carliae sp. n. is described from the blue-throated rainbow skink Carlia rhomboidalis (Peters), from Daintree Forest, North Queensland, Australia. Oocysts are ellipsoidal, 16.8-21.0 x 12.6-15.4 microm in size, with their two sporocysts, 9.0-14.0 x 7.0-9.24 microm in size, positioned along the wide axis. Sporozoites contain a distinct refractile body and are accompanied by a residuum. Al...

This report describes a case of granulomatous endometritis caused by coccidiosis in an immunologically uncompromised 63 year old patient. The glandular epithelium of the endometrium contained numerous intracytoplasmic cysts, corresponding to periodic acid Schiff positive and methenamine silver negative sporoblasts. The endometrial glands revealed reactive phenomena, such as eosinophilic and squ...

In the period October 2002–September 2004 we examined 2 996 samples of faeces of piglets at the age of 2–47 days. Samples were collected as so called “composite” ones from the pen floor. Samplings were done in 8 herds in Ceske Budejovice district. One herd was kept on the slatted floor, the other herds were housed on litter. Coprological examinations were carried out within 24 hours after sampl...

Sir, In resource limited countries such as India, parasitic enteric infections remain common in the general population and in the HIV infected, with geographic differences in the reported prevalence of individual pathogens reflecting differences in pathogen prevalence, standards of hygiene and diagnostic methods used.1,2 In this study, we report the prevalence of enteric parasites in HIV positi...
