Studies on Cryopreservation of Cryptosporidium parvum

The Journal of Parasitology, 1991
Neonatal BALB/c mice received oocysts or sporozoites of Cryptosporidium parvum pretreated by a variety of cryopreservation protocols. Histologic sections of infected and control mice were examined to determine if pretreated organisms established infection in the intestine. Sporozoites were inoculated rectally, oocysts orally.

Interaction of Lectins with Cryptosporidium parvum

Journal of Infectious Diseases, 1993
Cell surface carbohydrates from four clinical isolates of Cryptosporidium parvum were analyzed by agglutination assays using a battery of 20 highly purified lectins with affinity for receptor molecules containing N-acetyl-D-glucosamine (GlcNAc), N-acetyl-D-galactosamine, galactose, mannose, glucose, fucose, and N-acetyl-neuraminic acid.

Effects of curcumin on Cryptosporidium parvum in vitro

Parasitology Research, 2009
Cryptosporidium parvum is a zoonotic protozoan parasite having peculiarities among the apicomplexa that could be responsible for its resistance to some drugs and disinfectants against coccidia. The awareness of Cryptosporidium as a health problem in man and animal is increasing and potent drugs are urgently needed.

Cellular biology of Cryptosporidium parvum

Parasitology Today, 1993
With the emergence of Cryptosporidium parvum as a major pathogen encountered in human and veterinary clinical practice, a need for increased knowledge of the cellular- and immuno-biology of this Apicomplexan parasite has developed. Initial work has used paradigms taken from other Apicomplexans, especially Plasmodium, Toxoplasma and Eimeria, as a ...

Population genetics of Cryptosporidium parvum

Trends in Parasitology, 2004
Among the apicomplexan parasites of medical interest, Cryptosporidium is the least studied. Consistent with other members of this phylum, the generally accepted life cycle of Cryptosporidium comprises a sexual phase during which gamete differentiation and fertilization occurs. This process can affect the population structure of this parasite because of

Identification of invasion proteins of Cryptosporidium parvum

World Journal of Microbiology and Biotechnology, 2015
Host cell interactions and invasion by Cryptosporidium is a complex process mediated by zoites ligand-host cell receptors. Knowledge of proteins involved in this process will enable entry level inhibitors to be tried as therapeutic agents. In the present study, invasion proteins of Cryptosporidium parvum were studied in vitro.

Ultrastructural analysis of the sporozoite of Cryptosporidium parvum

Microbiology, 1998
Summary: Cryopreparation of live sporozoites and oocysts of the apicomplexan parasite Cryptosporidium parvum, followed by transmission electron microscopy, was undertaken to show the 3D arrangement of organelles, their number and distribution. Profiles of parasites obtained from energy-filtering transmission electron microscopy of serial sections ...

Experimental Cryptosporidium parvum Infections in Chickens

The Journal of Parasitology, 1987
Levine (1984, Journal of Protozoology 31: 9498) reviewed taxonomy and cross-transmission studies of members of the genus Cryptosporidium (Apicomplexa: Cryptosporidiidae). Based on the class of vertebrate that they infected, he considered that there were 4 valid species: Cryptosporidium muris Tyzzer, 1907, in mammals, C.

Adenosine kinase from Cryptosporidium parvum

Molecular and Biochemical Parasitology, 2006
Analysis of the Cryptosporidium parvum genome demonstrates that the parasite cannot synthesize purines de novo and reveals that the sole route for purine salvage by the parasite is via adenosine kinase (CpAK). In order to initiate a biochemical characterization of CpAK and ultimately validate this apparently essential enzyme as a therapeutic target ...

The unusual mitochondrial compartment of Cryptosporidium parvum

Trends in Parasitology, 2005
Recent studies, including the Cryptosporidium parvum Genome Project, have provided evidence for a mitochondrial-derived compartment in this parasite. This organelle appears to lack a genome, and thus must be entirely dependent on nuclear-encoded proteins. Here, we review the evidence for such an organelle in C. parvum and its probable function.
