Simplified methods for obtaining purified oocysts from mice and for growing Cryptosporidium parvum in vitro

, 1996
Seven- to 8-day-old Arc/Swiss mice were infected with 100,000-120,000 Cryptosporidium parvum oocysts. At 8 days postinfection (PI) the jejunum, ileum, cecum, colon, and rectum were removed.

Transient transfection of Cryptosporidium parvum using green fluorescent protein (GFP) as a marker

, 2009
Cryptosporidium parvum is a protozoan parasite that infects a variety of mammals. The parasite has been shown to harbor a dsRNA virus (CPV) and in the present study, we have developed a CPV transient transfection system for this parasite by using green ...

Common occurrence of Cryptosporidium hominis in asymptomatic and symptomatic calves in France.

PLoS Neglected Tropical Diseases, 2018
BackgroundCryptosporidium spp. infections are the most frequent parasitic cause of diarrhea in humans and cattle. However, asymptomatic cases are less often documented than symptomatic cases or cases with experimentally infected animals. Cryptosporidium (

Impact of predicted microbiota tryptophanase activity on Cryptosporidium parvum proliferation.

PLoS ONE
Protozoa in the genus Cryptosporidium infect intestinal epithelial cells. The profile of the fecal microbiota has been shown to impact the proliferation of Cryptosporidium parvum in a mouse model of cryptosporidiosis and a reverse effect of the parasite ...

Sequence differences in the diagnostic target region of the oocyst wall protein gene of Cryptosporidium parasites

, 2000
Nucleotide sequences of the Cryptosporidium oocyst wall protein (COWP) gene were obtained from Various Cryptosporidium spp. (C. wrairi, C. felis, C. meleagridis, C. baileyi, C. andersoni, C. muris, and C. serpentis) and C. parvum genotypes (human, bovine,

Cryptosporidium parvum in Oysters from Commercial Harvesting Sites in the Chesapeake Bay

Emerging Infectious Diseases, 1999
Oocysts of Cryptosporidium parvum, a zoonotic waterborne pathogen, can be removed by bivalve molluscs from contaminated water and retained on gills and in hemolymph. We identified oocysts of C.

Apical exosomes released from C. parvum-infected biliary epithelium display anti-C. parvum activity.

, 2013
(A) Effects of incubation with isolated exosomes from the biliary epithelium on C. parvum viability. Exosomes were isolated from the basolateral or apical supernatants of H69 monolayers of non-infected control, cells of C.
