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.
It is not readily transmissible from one species of host to another because it requires a period of time to adjust to the symbiotic flora of the new host. Once it has adapted to a host species, the protozoan can become a serious pathogen, especially in humans. Trophozoites multiply and encyst due to the dehydration of feces. [6]
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.
Blind loop syndrome, also known as stagnant loop syndrome, [1] is a state that occurs when the normal bacterial flora of the small intestine proliferates to numbers that cause significant derangement to the normal physiological processes of digestion and absorption.
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 ...
While VAD can make measles worse, Vitamin A supplements do not prevent measles, high doses may be dangerous, and vaccines remain the most effective was to prevent the disease. [ 17 ] The reason for the increased infection rate in vitamin A deficient individuals is that killer T-cells require the retinol metabolite retinoic acid to proliferate ...
Since odor detection may be an indicator that exposure to certain chemicals is occurring, olfactory fatigue can also reduce one's awareness about chemical hazard exposure. Olfactory fatigue is an example of neural adaptation. The body becomes desensitized to stimuli to prevent the overloading of the nervous system, thus allowing it to respond ...
