BACKGROUND: Intestinal parasitic infections and HIV/AIDS have been the major public health problems and remain a vital cause of morbidity and mortality in developing countries. Both problems are linked in a vicious cycle. The magnitude of intestinal parasites was prevalent among people living with HIV/AIDS even in the HAART era. However, the pertinent risk factors associated with intestinal parasites among HIV/AIDS patients were not well investigated in Ethiopia particularly at Butajira town...

The domestic pigeon, Columba livia domestica, is reared for meat production, as a pet, or for racing. Few reports have characterized the parasitic protists from the genus Isospora isolated from Columbiformes. We detected Isospora-like oocysts from C. livia reared for racing. The oocyst contained two sporocysts, and each sporocyst included four sporozoites. The sporulated oocysts (n=4) were spherical; their mean diameters were 25.6 (24.0-27.2)×24.7 (23.4-26.0) μm. Micropyles, polar granules, and oocyst residuum were absent...

BACKGROUND: Diarrhoea is an important cause of both morbidity and mortality among children in India. Coccidian parasitic infections are an important cause of diarrhea in immunocompromised patients, but their investigations are rarely sought by the treating physicians in seemingly immunocompetent children. This study was aimed to find the incidence rate of coccidian parasites in all children presented with diarrhoea, irrespective of their immune status. MATERIALS AND METHODS: Between December 2015 and May 2016, all fecal samples from children aged between 0 and 15 years presenting with diarrhoea, irrespective of their immune status, were examined using conventional wet mount and modified acid-fast staining...

BACKGROUND Strongyloides stercoralis infection is endemic in subtropical and tropical regions but is reported rather sporadically in temperate countries. In the USA, the highest rates of infection are from the southeastern states, predominantly among immigrants. There is paucity of case reports on S. stercoralis infection among HIV-infected patients who were born and raised in the USA. CASE REPORT A 61-year-old male with known HIV infection (CD4 count: 235 cells/uL, undetectable HIV RNA, on antiretroviral therapy) presented with a 3-month history of diarrhea...

Between 1996 and 2013, 71 blue-crowned laughingthrush (Dryonastes courtoisi) chicks, a small passerine bird endemic to China, were born at Mulhouse Zoo in northeast France. None of them survived past 1 yr, and 82% died between 0 and 6 days old of an unidentified cause and despite an attempt to establish an artificial breeding protocol. Atoxoplasma spp., causing a disease known as systemic isosporosis, is a coccidian parasite that can infect several species of birds. Mulhouse's adult birds were suspected to be infected with Atoxoplasma spp...

The genus term Isospora is now applied specifically to parasites of birds, with the term Cystoisospora preferred for parasites which infect mammals. Isospora is a common parasitic coccidian in birds worldwide, especially in passerine birds, in which it can cause systemic coccidiosis. The complete mitochondrial genome sequences from two recently identified Isospora species; Isospora serinuse in a domestic canary and Isospora manorinae in a yellow-throated miner, were sequenced and compared with those of other closely related coccidian species...

Eimeria pileata Soriano-Vargas, Medina, Salgado-Miranda, García-Conejo, Galindo-Sánchez, Janczur, Berto and Lopes, 2015 is a junior homonym of Eimeria pileata Straneva and Kelley, 1979 and needs to be replaced. This coccidium was described from a rufous-capped brush finch Atlapetes pileatus Wagler in the Nevado de Toluca Natural Protected Area, Mexico. Thus, to maintain the original intent of the specific epithet derived from the scientific name of the type-host, the name Eimeria atlapetesi nom. nov. is proposed as a replacement name...

BACKGROUND: The genome of the apicomplexan parasite Cystoisospora suis (syn. Isospora suis) has recently been sequenced and annotated, opening the possibility for the identification of novel therapeutic targets against cystoisosporosis. It was previously proposed that a 42 kDa uncharacterized merozoite protein, encoded by gene CSUI_005805, might be a relevant vaccine candidate due to its high immunogenic score, high expression level and species-specificity as determined in silico. METHODS: The 1170 bp coding sequence of the CSUI_005805 gene was PCR amplified and cloned into the bacterial expression vector pQE-31...
