Balantidiasis is a zoonotic disease and is acquired by humans via the fecal-oral route from the normal host, the pig, where it is asymptomatic. Fecally contaminated food and water are the common sources of infection in humans.
Balantidium is the only ciliated protozoan known to infect humans. Balantidiasis is a zoonotic disease and is acquired by humans via the feco-oral route from the normal host, the domestic pig, where it is asymptomatic.
Balantidiasis is the only ciliate known to be capable of infecting humans, and swine are the primary reservoir host. [27] Balantidiasis is opportunistic and rare in Western countries. [28] Apicomplexans are parasites of animals and contain an arrangement of organelles called the apical complex. One example of an apicomplexan is Malaria.
Balantidium coli is one of the species that has been reclassified. It has also been proposed that it is a junior synonym of genus Balantioides–which has B. coli as the type species. [6] The closest known relative of this genus is Buxtonella sulcata, a parasite of cattle.
The Balantidium coli species has a worldwide distribution, but is more frequent in subtropical and temperate climates. The medical condition balantidiasis is particularly prevalent where poor hygiene and undernourishment weaken a population coincide with living in close contact with pigs, the main reservoir for the species.
Scabies (also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple -like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually ...
Depending on the species of coccidia, infection can cause fever, vomiting, diarrhea, muscle pain, and nervous system effects and changes to behavior, and may lead to death. Healthy adults may recover without medication—but those who are immunocompromised or young almost certainly require medication to prevent death.
Preventive healthcare strategies are described as taking place at the primal, [2] primary, [13] secondary, and tertiary prevention levels. Although advocated as preventive medicine in the early twentieth century by Sara Josephine Baker, [14] in the 1940s, Hugh R. Leavell and E. Gurney Clark coined the term primary prevention.
