Poverty, parasitosis and HIV/AIDS are closely interlinked and co-circulate in many populations. HIV/AIDS, parasitic infections like malaria and other opportunistic infections, and in a few are by far the commonest causes of ill-health and death in the poorest countries of the world, that happen to be in the tropics and temperate countries in Africa, Asia, and South America. Parasitic infections...

This study was conducted to isolate Cryptosporidium from water sources in Al-Diwaniyah Governorate Where samples were collected during the period extending September 2021 February 2022, with a total of 500 distributed among three sources, namely, The percentage contamination (rivers, purification plants and liquefaction water) parasite 16%. results using interlaced polymerase chain reaction tec...

The outcome of drug induced pleurodesis has been evaluated in a non-randomised retrospective study of 67 patients with recurrent malignant pleural effusions treated during 1976-83. Fourteen died within 30 days of treatment. Of the remaining 53 patients, 26 studied during 1976-80 were treated with intrapleural mustine hydrochloride, while 27 studied during 1978-83 were treated with intrapleural ...

The parasite, Cryptosporidium parvum, induces human gastroenteritis through infection of host epithelial cells in the small intestine. During the initial stage of infection, C. parvum is reported to engage host mechanisms at the host cell-parasite interface to form a parasitophorous vacuole. We determined that upon infection, the larger molecular weight proteins in human small intestinal epithe...

BACKGROUND Although Chlamydia trachomatis is the most commonly reported pathogen that causes urogenital infection such as urethritis or cervicitis, Ureaplasma parvum and Ureaplasma urealyticum, which are commensals in the genital tract, have also now been recognized as contributors to urogenital infection. However, whether the presence of either U. parvum or U. urealyticum is related to that of...

BACKGROUND Cryptosporidium spp. are infections the most frequent parasitic cause of diarrhea in humans and cattle. However, asymptomatic cases are less often documented than symptomatic cases or cases with experimentally infected animals. Cryptosporidium (C.) hominis infection accounts for the majority of pediatric cases in several countries, while C. parvum is a major cause of diarrhea in neon...

Parasites of the genus Cryptosporidium infect the intestinal and gastric epithelium of different vertebrate species. Some of the many Cryptosporidium species described to date differ with respect to host range; whereas some species' host range appears to be narrow, others have been isolated from taxonomically unrelated vertebrates. To begin to investigate the genetic basis of Cryptosporidium ho...

Faecal specimens from 305 horses and mules used as packstock at one of 17 commercial or governmental (National Park Service, US Forest Service) operations were examined for Giardia duodenalis and Cryptosporidium parvum using immunofluorescent microscopy. Fourteen packstock (4.6%) were shedding G. duodenalis cysts, with herd-level prevalences ranging 0-22%. Number of packstock in the corral, siz...

Mice could be significantly protected against infection with herpes simplex virus (HSV) by i.p. or i.v. injection of killed Corynebacterium parvum 7 days before infection. This protection was seen in inbred strains of mice with a different degree of sensitivity to HSV and after both i.p. and i.v. infection. Resistant mice immunosuppressed by X-irradiation and showing an increased susceptibility...

Oocysts of a Cryptosporidium isolate from guinea pigs were not infectious for adult mice, but were infectious for two of three newborn calves and for suckling mice. However, oocysts isolated from calves or mice infected with guinea pig Cryptosporidium were not infectious for guinea pigs. Four isolates of C. parvum from calves were incapable of infecting weanling guinea pigs. Microscopic examina...
