The life cycle of Cryptosporidium begins with the ingestions of the sporulated, environmentally resistant oocysts by the susceptible host. Cryptosporidium infection results in several cellular damages such as the alteration of the cytoskeleton with the disruption of tight cell junctions, a loss of ...
Cryptosporidiumis a member of the eukaryotic phylum Apicomplexa and has a life cycle that alternates between asexual and sexual reproduction. However, in contrast to most other apicomplexans, the entire cycle occurs in a single host. Sex results in the production of oocysts, which are environmentall...
The family Cryptosporidiidae has a hidden sporocyst and undergoes monoxenous completion of its cycle in one host, where it can cause predominantly intestinal, cloacal, and gastric infections. Epidemiology The life cycle begins with ingestion of Cryptosporidium oocysts (2 to 5 µm) by the ...

Cryptosporidiumlife cycle Based on the developmental phases, the life cycle ofCryptosporidiumcan be sub-divided into six groups. The first stage is the excystation phase that releases infectious sporozoites, leading to the second stage of asexual proliferation within the host cell, called merogony. ...

The final product of the life cycle is the oocyst, which measures 4 to 6 μm in diameter and contains four infectious sporozoites. As in the case of Giardia and Entamoeba, there are numerous subgroups of Cryptosporidium. Cryptosporidium parvum and Cryptosporidium hominis are responsible for more ...
To investigate the function of NFDQ1 in the parasite life cycle, we utilized the luciferase-based growth assay to compare the growth of WT parasites with ΔNFDQ1 transgenic parasites. HCT-8 cells were infected with 104 oocysts per well for each strain. After specified times, cells were lysed...
A suite of phenotypic assays roughly based on theCryptosporidiumlife cycle was developed in order to generate phenotypic profiles of compounds. These assays were used to define a mode of action for different compounds, and then to determine if the mode of action can be used to distinguish compoun...
Cryptosporidium oocysts range in size from 2 to 8m, depending on the species and the stage of the life cycle. Oocysts are commonly found in many of the lakes and rivers that supply public drinking water as a result of runoff from sewage and animal wastes applied to nearby fields and ...
