Trichomonas vaginalis is an anaerobicflagellated protozoan parasite and the causative agent of trichomoniasis. It is the most common pathogenic protozoan infection of humans in industrialized countries. Transmission usually occurs via direct, skin-to-skin contact with an infected individual, most often through vaginal intercourse.

In the temperate climate zones, many familiar viral and bacterial diseases are spread directly from person to person, by airborne routes of transmission or by sexual contact. In the tropics, respiratory diseases such as measles, respiratory syncytial virus, tuberculosis and sexually transmitted diseases are also of great importance. In addition, many diseases are spread by contaminated water and food sources, since clean water and sanitary conditions are often a luxury in developing countries. The insect or other invertebrate vector picks up the pathogen from an infected person or animal and transmits it to others in the process of feeding.
Although symptoms of the disease vary, most women and men who have the parasite cannot tell they are infected. Trichomoniasis is considered the most common, curable STD. An estimated 3.
Parasites are organisms that live off other organisms, or hosts, to survive. Others grow, reproduce, or invade organ systems that make their hosts sick, resulting in a parasitic infection. Parasitic infections are a big problem in tropical and subtropical regions of the world.
These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune systemleading to inflammatory complications of protozoan infections. Antibiotic treatment can clear the parasite but does not prevent some of these complications. Half of T.
Numerous protozoa inhabit the gastro-intestinal tract of humans see Box. This list includes representatives from many diverse protozoan groups. The majority of these protozoa are non-pathogenic commensals, or only result in mild disease.
