Wuchereria bancrofti is a filarial (arthropod-borne) nematode (roundworm) that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with Brugia malayi and B. timori, that infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species. W. bancrofti is the most prevalent of the three and affects over 120 million people, primarily in Central Africa and the Nile delta, South and Central America, the tropical regions of Asia including southern China, and the Pacific islands. If left untreated, the infection can develop into a chronic disease called lymphatic filariasis. In rare conditions, it also causes tropical eosinophilia, an asthmatic disease. No vaccine is commercially available, but high rates of cure have been achieved with various antifilarial regimens and lymphatic filariasis is the target of the WHO Global Program to Eliminate Lymphatic Filariasis with the aim to eradicate the disease as a public-health problem by 2020.
Scrub typhus or bush typhus is a form of typhus caused by the intracellular parasite Orientia tsutsugamushi, a Gram-negative α-proteobacterium of family Rickettsiaceae first isolated and identified in 1930 in Japan.
Hymenolepiasis is infestation by one of two species of tapeworm: Hymenolepis nana or H. diminuta. Alternative names are dwarf tapeworm infection and rat tapeworm infection. The disease is a type of helminthiasis which is classified as a neglected tropical disease.
Fasciolopsiasis results from an infection by the trematode Fasciolopsis buski, the largest intestinal fluke of humans.
Hookworm infection is an infection by a type of intestinal parasite known as a hookworm. Initially, itching and a rash may occur at the site of infection. Those only affected by a few worms may show no symptoms. Those infected by many worms may experience abdominal pain, diarrhea, weight loss, and tiredness. The mental and physical development of children may be affected. Anemia may result.
Eosinophiluria is the abnormal presence of eosinophils in the urine. It can be measured by detecting levels of eosinophil cationic protein.
Plasmodium chabaudi is a parasite of the genus Plasmodium subgenus Vinckeia. As in all Plasmodium species, P. chabaudi has both vertebrate and insect hosts. The vertebrate hosts for this parasite are rodents.
Angiostrongyliasis is an infection by a roundworm of the Angiostrongylus type. Symptoms may vary from none, to mild, to meningitis.
Carbarsone is an organoarsenic compound used as an antiprotozoal drug for treatment of amebiasis and other infections. It was available for amebiasis in the United States as late as 1991. Thereafter, it remained available as a turkey feed additive for increasing weight gain and controlling histomoniasis.
Dhori virus (DHOV) is a species of the genus Thogotovirus and a member of the family Orthomyxoviridae. Its hosts are ticks, mosquitoes, and mammals. DHOV is lethal to mice, causing systemic pathologic changes similar to those reported in humans with virulent influenza A (H5N1) virus infection.
The Kato technique is a laboratory method for preparing human stool samples prior to searching for parasite eggs.
Plasmodium youngi is a protozoan parasite which can cause malaria in certain primates. It is known to infect and cause severe disease in Malayan gibbons.
Oesophagostomum is a genus of parasitic nematodes (roundworms) of the family Strongylidae. These worms occur in Africa, Brazil, China, Indonesia and the Philippines. The majority of human infection with Oesophagostomum is localized to northern Togo and Ghana. Because the eggs may be indistinguishable from those of the hookworms, the species causing human helminthomas are rarely identified with accuracy. Oesophagostomum, especially O. bifurcum, are common parasites of livestock and animals like goats, pigs and non-human primates, although it seems that humans are increasingly becoming favorable hosts as well. The disease they cause, oesophagostomiasis, is known for the nodule formation it causes in the intestines of its infected hosts, which can lead to more serious problems such as dysentery. Although the routes of human infection have yet to be elucidated sufficiently, it is believed that transmission occurs through oral-fecal means, with infected humans unknowingly ingesting soil containing the infectious filariform larvae.
Brugia timori is a filarial (arthropod-borne) nematode (roundworm) which causes the disease "Timor filariasis", or "Timorian filariasis". While this disease was first described in 1965, the identity of Brugia timori as the causative agent was not known until 1977. In that same year, Anopheles barbirostris was shown to be its primary vector. There is no known animal reservoir host.
Fyodor Alexandrovich Lesh, alternatively spelled as Lösch (1840–1903), was a Russian Empire medical doctor.
The Mazzotti reaction, first described in 1948, is a symptom complex seen in patients after undergoing treatment of nematode infestation, particularly with the medication diethylcarbamazine (DEC). Mazzotti reactions can be life-threatening, and are characterized by fever, urticaria, swollen and tender lymph nodes, tachycardia, hypotension, arthralgias, oedema, and abdominal pain that occur within seven days of treatment of microfilariasis. The Mazzotti reaction correlates with intensity of infection; however, there are probably multiple infection intensity-dependent mechanisms responsible for mediating this complex reaction.
Tete orthobunyavirus is a bunyavirus found originally in Tete Province, Mozambique. It is a disease of animals and humans. Two forms, Bahig and Matruh viruses, were isolated from bird ticks including Hyalomma marginatum, but elsewhere mosquitoes and biting midges have been implicated as vectors.
Cryptosporidium muris is a species of coccidium, first isolated from the gastric glands of the common mouse. Cryptosporidium does originate in common mice, specifically laboratory mice. However, it also has infected cows, dogs, cats, rats, rabbits, lambs, and humans and other primates.
Tensaw orthobunyavirus is a virus in the genus Orthobunyavirus of the Bunyamwera arbovirus group, order Bunyavirales. It is named for the river bordering the area in south Alabama where the prototype strain was discovered. It is abbreviated TEN, TENV, and TSV in the scientific literature.
Haemaphysalis spinigera, is a hard-bodied tick of the genus Haemaphysalis. It is found in India, Sri Lanka, Vietnam. It is an obligate ectoparasite of mammals of various rodents, insectivores and monkeys. It is a potential vector of Kyasanur Forest disease virus, and Kaisodi virus.
