| isospora | A genus of protozoan parasites found in the intestines of birds, amphibians, reptiles, and mammals, including man. The oocysts produce two sporocysts, each with four sporozoites. Many species are parasitic in wild and domestic animals. (12 Dec 1998) |
|---|---|
| Isospora belli | A relatively rare species occurring in the small intestine of man, most common in the tropics but probably of worldwide distribution; most infections are subclinical, but sometimes they may cause mucous diarrhoea. (05 Mar 2000) |
| Isospora bigemina | A species that occurs in the small intestine of the dog, cat, fox, mink, and possibly other carnivores; the most pathogenic coccidium in dogs and cats, causing enteritis and diarrhoea; the oocysts are usually sporulated when passed in the faeces, but are indistinguishable from those of Toxoplasma gondii, so considerable question remains as to the status of these parasites. (05 Mar 2000) |
| Isospora canis | A species of worldwide distribution that is mildly pathogenic in dogs and is not infective in cats. (05 Mar 2000) |
| Isospora felis | A species found in the small intestine and sometimes the caecum and colon of cats, lions, and other felids; it is only slightly, if at all, pathogenic in cats and is not infective in dogs. (05 Mar 2000) |
| Isospora rivolta | A species that occurs in the small intestine of dogs, cats, dingos, and probably other wild carnivores; pathogenic capabilities are similar to those of Isospora bigemina. (05 Mar 2000) |
| Isospora suis | A species that affects the small intestine of the pig, producing mild diarrhoea. (05 Mar 2000) |
| blastocystis hominis | A species of parasitic protozoa found in the intestines of humans and other primates. It was classified as a yeast in 1912. Over the years, questions arose about this designation. In 1967, many physiological and morphological b. Hominis characteristics were reported that fit a protozoan classification. Since that time, other papers have corroborated this work and the organism is now recognised as a protozoan parasite of humans causing intestinal disease with potentially disabling symptoms.

| Gastrodiscoides hominis | A species of trematode sometimes found in the intestinal canal of man in India, Southeast Asia, and China; its normal host is the pig. Synonym: Gastrodiscus hominis. Origin: Gastro-+ G. Diskos, disk; L. Homo, gen. Hominis, man (05 Mar 2000) |
| Gastrodiscus hominis | A species of trematode sometimes found in the intestinal canal of man in India, Southeast Asia, and China; its normal host is the pig. Synonym: Gastrodiscus hominis. Origin: Gastro-+ G. Diskos, disk; L. Homo, gen. Hominis, man (05 Mar 2000) |
| gastrospirillum hominis | A species of gram-negative, spiral-shaped bacteria found in the gastric mucosa that is associated with chronic antral gastritis. This bacterium was first discovered in samples removed at endoscopy from patients investigated for helicobacter pylori colonization. (12 Dec 1998) |
| poliovirus hominis | The picornavirus (genus Enterovirus) causing poliomyelitis in humans; the route of infection is the alimentary tract, but the virus may enter the bloodstream and nervous system, sometimes causing paralysis of the limbs and, rarely, encephalitis; many infections are inapparent; serologic types 1, 2, and 3 are recognised, type 1 being responsible for most paralytic poliomyelitis and most epidemics. Synonym: poliovirus hominis, poliovirus. (05 Mar 2000) |
| mycoplasma hominis | A common inhabitant of the vagina and cervix and a potential human pathogen, causing infections of the male and female reproductive tracts. It has also been associated with respiratory disease and pharyngitis. (12 Dec 1998) |
| polyomavirus hominis 1 | <virology> A species of polyomavirus apparently infecting over 90% of children but not clearly associated with any clinical illness in childhood. The virus remains latent in the body throughout life and can be reactivated under certain circumstances. (12 Dec 1998) |
| polyomavirus hominis 2 | <virology> A species of polyomavirus, originally isolated from the brain of a patient with progressive multifocal leukoencephalopathy. The patient's initials j.c. Gave the virus its name. Infection is not accompanied by any apparent illness but serious demyelinating disease can appear later, probably following reactivation of latent virus. (12 Dec 1998) |
