• Parasites
  • Parasites of Bithynia siamensis include trematode Multicotyle purvisi. (wikipedia.org)
  • These parasites are long-lived and cause heavy chronic infections that may lead to accumulation of fluid in the legs (edema) and in the peritoneal cavity (ascites), enlarged non-functional gall-bladder and also cholangitis, which can lead to periductal fibrosis, cholecystitis and cholelithiasis, obstructive jaundice, hepatomegaly and/or fibrosis of the periportal system. (wikipedia.org)
  • Bacterial
  • Secondary bacterial infection causing cholangitis has also been a concern and can be treated with antibiotics, and toxaemia may be treated with prednisolone. (wikipedia.org)
  • species
  • Lesser known FBT have been reported in the USA including species of Alaria , echinostomids, heterophyids, troglotrematids, and a self-induced infection of Plagiorchis . (springer.com)
  • The species name P. westermani was named after Pieter Westerman (1859-1925) a zookeeper who noted the trematode in a Bengal tiger in an Amsterdam Zoo[Artis]. (wikipedia.org)
  • hookworm
  • This is most severe in heavy hookworm infections, as Necator americanus and Ancylostoma duodenale feed directly on the blood of their hosts. (wikipedia.org)
  • eggs
  • Infection with worms transmitted through ingestion of or direct exposure to soil that is contaminated by human feces in which STH eggs are present. (kff.org)
  • Fecal examination is generally not helpful because the worm eggs can seldom be detected in the chronic phase of the infection. (wikipedia.org)
  • Eggs appear in the feces first between 9-11 weeks post-infection. (wikipedia.org)
  • Radiological methods can detect lesions in both acute and chronic infection, while laparotomy will detect lesions and also occasionally eggs and live worms. (wikipedia.org)
  • Infection is considered heavy when there are 10,000-30,000 eggs in one gram of feces. (wikipedia.org)
  • NTDs
  • Neglected tropical diseases ( NTDs ) are a diverse group of tropical infections which are especially common in low-income populations in developing regions of Africa , Asia , and the Americas . (wikipedia.org)
  • Women and children are most at risk of infection, since they are more exposed to NTDs and more often face barriers to accessing treatment, particularly those living in remote areas. (kff.org)
  • intensity of infection
  • In 1912, Harujiro Kobayashi corrected the classification that the differences in sizes were due to the nature of the host and intensity of infection, and had nothing to do with the biology. (wikipedia.org)
  • Human
  • We report the first confirmed human pulmonary paragonimiasis case caused by P. pseudoheterotremus infection. (ajtmh.org)
  • Soil-transmitted helminthiases are responsible for parasitic infections in as much as a quarter of the human population worldwide. (wikipedia.org)
  • It is the most prevalent human trematode in Asia, and is still transmitted in Korea, China, Vietnam and also Russia, with 200 million people at constant risk. (wikipedia.org)
  • Human infection is rare, even if the infection rate is high among animals. (wikipedia.org)
  • Especially high rates of human infection have been found in Bolivia, Peru and Egypt, and this may be due to consumption of certain foods. (wikipedia.org)
  • Veterinary vaccines are in development, and their use is being considered by a number of countries on account of the risk to human health and economic losses resulting from livestock infection. (wikipedia.org)
  • Human infections are most common in eastern Asia and in South America. (wikipedia.org)
  • severity
  • Although progress has been made for the limitation of the disease severity by chemotherapy, continuous re-infection and risks of drug resistance point to the necessary development of alternative strategies. (clinicaltrials.gov)
  • adult
  • This correlation between anti-fecundity effects and inhibition-mediated antibodies demonstrated in several animal models was re-enforced by epidemiological studies showing that such acquired antibodies produced during infection could be detected in adult individuals naturally resistant to the re-infection. (clinicaltrials.gov)
  • A recent epidemiological study found an association between S. mansoni and HIV infection in adult women residing near Lake Victoria in Tanzania. (clinicaltrials.gov)
  • The body of the adult disease-causing agent of metagonimiasis is often described as leaf-shaped, similar to most trematodes. (wikipedia.org)
  • acute
  • In acute metagonimiasis, clinical manifestations are developed only 5-7 days after infection. (wikipedia.org)
  • An interesting case in Japan found Diabetes Mellitus (DM) to be a sign of chronic infection with intracerebral hemorrhages as the acute sign of aggravation. (wikipedia.org)
  • endemic
  • However only limited proportion of subjects with infection develop this pathology and there is limited knowledge on risk factors for the differential morbidity patterns observed in endemic communities. (clinicaltrials.gov)
  • heavy
  • Although the daily consumption of an individual worm (0.02-0.07 ml and 0.14-0.26 ml respectively) is small, the collective consumption under heavy infection can be clinically significantly. (wikipedia.org)
