• Entamoeba Histolytica
  • Protozoans have little in common with each other (for example, Entamoeba histolytica, an unikont eukaryotic organism, is less closely related to Naegleria fowleri, a bikont eukaryotic organism, than it is to Homo sapiens, which belongs to the unikont phylogenetic group) and so agents effective against one pathogen may not be effective against another. (wikipedia.org)
  • Invasive colitis and extraintestinal disease including liver abscesses, pleuropulmonary infections, and brain abscesses can result from infection with Entamoeba histolytica. (wikipedia.org)
  • fecal-oral
  • Those protozoans that have inhabited the human intestine can be transmitted from one human to another via the fecal-oral route, such as through sharing food the infected person has touched and through direct person to person contact. (blogspot.com)
  • Infection is transmitted through the fecal-oral route, and begins when a person ingests oocysts in fecally contaminated food or water. (wikipedia.org)
  • enteric

  • This research is significant since it provides the most recent epidemiological update on the common enteric protozoa affecting Australians. (jphres.org)
  • It reveals that enteric protozoa cause considerable disease burden in high risk city dwellers, and provides the evidence base for development of targeted interventions for their prevention and control in high risk populations. (jphres.org)
  • The prevalence of enteric protozoa in this metropolitan setting underscores that microorganisms do not respect borders and that a collaborative approach is needed to contain the global spread of infectious diseases. (jphres.org)
  • Few epidemiological studies have shown that enteric infections are associated with exacerbations of ulcerative colitis (UC). (ecco-ibd.eu)
  • prevalence
  • Compared with those without G. lamblia , children with G. lamblia infections had lower weight-for-age and weight-for-height z -scores and were more than five times as likely to meet the z -score definition for wasting (prevalence ratio = 5.42, 95% CI = 2.97-9.89). (ajtmh.org)
  • The age distribution showed that the prevalence of protozoa decreased with age up to 24 years but increasing with age from 25 years onwards. (jphres.org)
  • motile

  • acute
  • Moreover, bacterial infection is an important concomitant of both the treatment and outcome of acute graft versus host disease (GVHD). (springer.com)
  • Infection causes acute, non-bloody diarrhea with crampy abdominal pain, which can last for weeks and result in malabsorption and weight loss. (wikipedia.org)
  • Where the site of infection is easily accessed, antibiotics may be given topically in the form of eye drops onto the conjunctiva for conjunctivitis or ear drops for ear infections and acute cases of swimmer's ear. (wikipedia.org)
  • AIDS
  • Infection often occurs in immuno-compromised individuals, notably AIDS patients, and outbreaks have been reported in institutionalized groups in the United States. (wikipedia.org)
  • Some of the complications of T. vaginalis in women include: preterm delivery, low birth weight, and increased mortality as well as predisposing to HIV infection, AIDS, and cervical cancer. (wikipedia.org)
  • occurs
  • Fungal infection occurs less commonly than bacterial infection, but with a higher case fatality rate. (springer.com)
  • The symptoms of M. perstans may be confounded with those of other filarial infections, such as onchocerciasis, lymphatic filariasis and loiasis, because coinfection often occurs. (wikipedia.org)
  • Infection occurs by ingestion of sporocyst-containing oocysts: the sporocysts excyst in the small intestine and release their sporozoites, which invade the epithelial cells and initiate schizogony. (wikipedia.org)
  • trypanosomiasis
  • This disease also called trypanosomiasis is caused by a protozoa, which are carried by the tsetse fly and are transmitted to human tsetse fly bite. (blogspot.com)

  • Fungal
  • AmBisome (LAMB) is a liposomal formulation of amphotericin B for injection and consists of a mixture of phosphatidylcholine, cholesterol and distearoyl phosphatidylglycerol that in aqueous media spontaneously arrange into unilamellar vesicles that contain amphotericin B. Guidelines recommend the use of LAMB for CNS fungal infections due to better pharmacokinetics and CNS penetration but do note that this is based only on animal models. (wikipedia.org)
  • In the past it had been used for fungal infections of the surface of the GI tract such as thrush, but has been replaced by other antifungals such as nystatin and fluconazole. (wikipedia.org)
  • clinical
  • We selected 580 cases which had residence post code data available, enabling us to examine the geographic distribution of patients, and reviewed the clinical data of 252 patients to examine possible links between protozoa, demographic and clinical features. (jphres.org)
  • cause
  • Although bacterial infection as a primary cause of death is rare, such infection may add substantially to the morbidity and cost of transplantation. (springer.com)
  • Food and water contaminated by feces is the common route of transmission, however, oral contact with fecal matter can also cause infection. (blogspot.com)

  • M. perstans as the cause of African trypanosomyasis was later ruled out by the Royal Society Sleeping Sickness Commission, who showed the geographical distribution of sleeping sickness did not coincide with that of M. perstans infection. (wikipedia.org)
  • This is because amphotericin B resistance requires sacrifices on the part of the pathogen that make it susceptible to the host environment, and too weak to cause infection. (wikipedia.org)
  • recur
  • Swelling may occur at different times after the initial infection, persist, and recur for various times independently of antiparasitic treatment. (wikipedia.org)
