  • cysts
  • 3 Giardia cysts are infectious immediately upon being excreted in feces and remain viable for at least 3 months in water at 4°C. 4 Freezing does not eliminate infectivity completely, whereas heating, drying, or submersing in seawater are likely to do so. (nih.gov)
  • Infection with Giardia can occur directly by the fecal-oral route or indirectly via ingestion of contaminated water or food, but water contaminated with cysts appears to be the major reservoir and vehicle for spread of the parasite. (nih.gov)
  • giardiasis
  • 6 There is a paucity of information on giardiasis in HIV-infected children, although Giardia has been associated with diarrhea in children with AIDS. (nih.gov)
  • Cyst
  • After ingestion, each Giardia cyst produces two trophozoites in the proximal portion of the small intestine. (nih.gov)
  • cyst
  • Giardia cyst or trophozoite were identified in samples using direct wet mount and formalin-ether sedimentation technique by microscopic observation (Zeiss, Germany, 40X magnification). (alliedacademies.org)
  • Vibrio
  • The Vibrio species vaccine is available but only protects 50% of immunized persons for 3-6 months. (medscape.com)
  • History of raw seafood ingestion or foreign travel should prompt additional screening for Vibrio and Plesiomonas species. (medscape.com)
  • Salmonella
  • At times, a protein-losing enteropathy can be found in patients with extensive inflammation in the course of enteroinvasive intestinal infections (eg, Salmonella species, enteroinvasive E coli ). (medscape.com)
  • Helminths
  • We molecularly characterized samples with Giardia , Cryptosporidium , and soil-transmitted helminths from a facility-based surveillance system for diarrhea in Santa Rosa, Guatemala. (ajtmh.org)
  • Identification
  • Serology reagents intended to detect antigens that permit the identification of strains of species of Giardia, a genus of flagellated protozoa characterized by the presence of a large sucking disk in the ventral surface, that parasitize human intestines. (ophthalmologymanagement.com)
  • bacteria
  • This website provides extreme detail about the composition, length, structure, and function of flagellum, and has numerous links to the evolution and the various diverse containing species in the three groups: Bacteria, Archaea, and Eukaryotes. (sciforums.com)
  • different
  • The taxonomy of Giardia has been controversial for well over 100 years, resulting in a confusing nomenclature with different names often being used for the same species. (edu.au)
  • Relationships between host age, sex, and breed, season of presentation and the different species of Giardia detected were assessed. (biomedcentral.com)
