Cryptosporidium parvum: Is it Invincible?
Midsouth Entomologist, 2016Cryptosporidium is a coccidian protozoan parasite that can affect mammals, reptiles, and birds. A coccidian is a single-celled protozoan that affects the epithelial lining of the intestinal walls of hosts it parasitizes. This parasite has a unique life cycle and can withstand common measures of sterilization. The infective oocyte stage is resistant and

Cryptosporidium Parvum Gene Discovery
1999Cryptosporidium parvum is a well-recognized cause of diarrhea in humans and animals throughout the world, and is associated with a substantial degree of morbidity and mortality in patients with acquired immunodeficiency syndrome (AIDS). At the present time, there is no effective therapy for treating or preventing infection with C. parvum.

Cryptosporidium parvum studies with dairy products
International Journal of Food Microbiology, 1999Cryptosporidium parvum is a protozoan parasite capable of causing massive waterborne outbreaks. This study was conducted to model the transfer of C. parvum oocysts from contaminated water via food contact surfaces into yogurt and ice-cream, as well as to examine oocyst survival. Propidium iodide staining, combined with a direct immunofluorescence assay,

Gaseous disinfection of Cryptosporidium parvum oocysts
Applied and Environmental Microbiology, 1996Purified oocysts of Cryptosporidium parvum suspended in approximately 400 microliters of phosphate-buffered saline or deionized water in microcentrifuge tubes were exposed at 21 to 23 degrees C for 24 h to a saturated atmosphere of ammonia, carbon monoxide, ethylene oxide, formaldehyde, or methyl bromide gas. Controls were exposed to air.

Cryptosporidium Parvum in Children with Diarrhea in Mexico
The American Journal of Tropical Medicine and Hygiene, 1994Using an anti-oocyst wall monoclonal antibody-based immunofluorescence assay, the presence of Cryptosporidium parvum was evaluated in children with diarrhea from rural areas (selected from a door-to-door community survey) and from urban areas (patients attending hospitals) in the State of Puebla, Mexico.

Natural History and Biology of Cryptosporidium parvum
Advances in Parasitology, 1998The taxonomy of the genus Cryptosporidium remains ambiguous, because the current criteria for speciation are insufficient to validate the 6-8 named species. Cross-transmission experiments have shown varying and conflicting results, and the limited genetic data available do not necessarily support currently proposed species designations. The reasons for

The response of Cryptosporidium parvum to UV light
Trends in Parasitology, 2005Ultraviolet (UV) light is being considered as a disinfectant by the water industry because it appears to be very effective for controlling potential waterborne pathogens, including Cryptosporidium parvum. However, many organisms have mechanisms such as nucleotide excision repair and photolyase enzymes for repairing UV-induced DNA damage and regaining ...

Structural Analysis ofCryptosporidium parvum
Microscopy and Microanalysis, 2004Cryptosporidium parvum(Apicomplexa, formerly Sporozoa) is the causative agent of cryptosporidiosis, an enteric disease of substantial medical and veterinary importance.C. parvumshows a number of unique features that differ from the rest of the class of coccidea in which it is currently grouped taxonomically.
