  • malaria
  • 2. Any of various single-celled organisms (called protozoans) that exist as parasites in vertebrate animals, one of which causes malaria. (thefreedictionary.com)
  • RBCs carrying PfEMP1 on their surface stick to endothelial cells, which facilitates further binding with uninfected RBCs (through the processes of sequestration and rosetting), ultimately helping the parasite to both spread to other RBCs as well as bringing about the fatal symptoms of P. falciparum malaria. (wikipedia.org)
  • Before invading the RBCs and causing the symptoms of malaria, the parasites first multiply in the liver. (wikipedia.org)
  • blood
  • By the early 1980s, it was established that when the parasite (both the trophozoite and schizont forms) enters the blood stream and infects RBCs, the infected cells form knobs on their surface. (wikipedia.org)
  • infection
  • Foods can be the source for some zoonotic infection when animals such as cows and pigs are infected with parasites such as Cryptosporidium or Trichinella . (cdc.gov)
  • Parasites, such as Trypanosoma cruzi , might be found in the blood early in an infection (the acute phase) and then at much lower levels later (the chronic phase of infection). (cdc.gov)
  • There may be cases of transfusion-transmitted parasites that go undetected and unreported, but the risk for infection is very low compared with the number of blood transfusions. (cdc.gov)
  • Any three or more of these symptoms are associated with the Morgellons skin parasite plus a co infection of protozoan and or Lyme disease. (selfgrowth.com)
  • A significant focus is also given on the workings of immunology and how the immune systems of living beings respond to parasite infection, along with the methods that bodily functions are used to counteract and potentially kill invading microorganisms. (wikipedia.org)
  • The final chapters focus on an overall effect parasites have had on the evolution of life and the theory that it is due to parasitic infection that sexual reproduction evolved to become dominant, in contrast to previous asexual reproduction methods, due to the increased genetic variety and thus potential parasitic resistance that this would confer. (wikipedia.org)
  • Changes in a host's behaviour following infection with obligate parasites are extremely common. (wikipedia.org)
  • Feces
  • For example, people can be infected by the raccoon parasite Baylisascaris if they accidentally swallow soil that is contaminated with infected raccoon feces. (cdc.gov)
  • behavior
  • Toxoplasma gondii , the single-celled parasite that lives in roughly half of all people on Earth and has the ability to alter the behavior of its host. (scienceblogs.com)
  • They proposed that the shift in behavior was an adaptation of the parasite for getting into its final host-cats. (scienceblogs.com)
  • Parasite load has also been shown to affect the behavior of the infected individual. (wikipedia.org)
  • Numerous studies have been done looking at the effects of number of parasites present in a host and how this correlates with behaviors such as foraging, migration, and competitive behavior. (wikipedia.org)
  • wasp
  • Parasites are raising an army of zombie wasp queens to do t... ...o their bidding, and it's a good thing that these parasites aren't more ambitious, because they'd probably. (neatorama.com)
  • found
  • Many factors affect whether parasites that can be found in the bloodstream might be spread by blood transfusion. (cdc.gov)
  • This parasite is found in streams and lakes. (brighthub.com)
  • Other internal parasites are found living inside fish gills, include encysted adult didymozoid trematodes, a few trichosomoidid nematodes of the genus Huffmanela, including Huffmanela ossicola which lives within the gill bone, and the encysted parasitic turbellarian Paravortex. (wikipedia.org)
  • The book discusses the history of parasites on Earth and how the field and study of parasitology formed, along with a look at the most dangerous parasites ever found in nature. (wikipedia.org)
  • According to Canadian biologist Dorothy Kieser, the myxozoan parasite Henneguya salminicola is commonly found in the flesh of salmonids. (wikipedia.org)
  • One study found that parasite load predicts mate choice in guppies. (wikipedia.org)
  • In a study performed at the University of Georgia, it was found that beetles with higher parasite loads won more fights than those with lower parasitic loads. (wikipedia.org)
  • Practice
  • This is a common practice in veterinary medicine and is used to calculate parasite load in domestic animals, such as cats and dogs. (wikipedia.org)
  • 20th
  • Until the middle of the 20th century there was military interest in parasite fighters - fighter aircraft intended to be carried into a combat zone by a larger aircraft, such as a bomber. (wikipedia.org)
  • spread
  • While the parasite can be spread in different ways, water (drinking water and recreational water) is the most common mode of transmission. (cdc.gov)
  • the parasite might be spread to other people through exposure to an infected person's blood (for example, by blood transfusion or by sharing needles or syringes contaminated with blood). (cdc.gov)
  • carry
  • Pets can carry parasites and pass parasites to people. (cdc.gov)
  • Two parasites mate and their offspring-egg-like cells called oocysts-carry a mix of their genes. (scienceblogs.com)
  • The tests were a success, and the purpose built airships USS Akron and USS Macon were designed to carry parasite aircraft inside a hangar bay within the hull. (wikipedia.org)
  • The first bombers to carry parasite fighters did so as part of the Zveno experiments carried out in the Soviet Union by Vladimir Vakhmistrov from 1931. (wikipedia.org)
  • In vertebrates, males frequently carry higher parasite loads than females. (wikipedia.org)
  • common
  • Such investigations are considerably more common in third-world countries where endemic parasitoses are more readily documented.1 In an attempt to address this problem we reported the results of routine examination of fecal specimens for parasites from 644 patients in the United States during the summer of 1996. (wikipedia.org)
  • males
  • Often males have larger habitat ranges and thus are likely to encounter more parasite-dense areas than female conspecifics. (wikipedia.org)
  • Therefore, females will select males with few or no parasites by basing their choice on whether or not the male has fully expressed secondary sexual, otherwise known as 'healthy' characteristics. (wikipedia.org)
  • When controlling for other variables, females were shown to prefer males with relatively few parasites with this preference being associated with higher display rates that occur in less parasitized males. (wikipedia.org)
  • differences
  • Differences in movement patterns, habitat choice, diet, body size, and ornamentation are all thought to contribute to this sex bias observed in parasite loads. (wikipedia.org)
  • example
  • Unusual behaviour observed in infected individuals is noted, and if its complexity suggests that this behaviour will benefit the transmission of the parasite, then this is said to be an example of adaptive manipulation. (wikipedia.org)
  • usually
  • Clinically, the life-long presence of the parasite in tissues of a majority of infected individuals is usually considered asymptomatic. (wikipedia.org)
  • family
  • Make sure your pet is under a veterinarian's care to help protect your pet and your family from possible parasite infections. (cdc.gov)
  • Before either had realized that they were dealing with skin parasites, four other family members were infected because of physical contact (sitting in chairs. (selfgrowth.com)
