The Cryptosporidium parvum transcriptome during in vitro development.

ABSTRACT: Cryptosporidiosis is caused by an obligate intracellular parasite that has eluded global transcriptional or proteomic analysis of the intracellular developmental stages. The transcript abundance for 3,302 genes (87%) of the Cryptosporidium parvum protein coding genome was elucidated over a 72 hr infection within HCT8 cells using Real Time-PCR. The parasite had detectable transcription of all genes in vitro within at least one time point tested, and adjacent genes were not co-regulated. Five genes were not detected within the first 24 hr of infection, one containing two AP2 domains. The fewest genes detected were at 2 hr post infection, while 30% (985) of the genes have their highest expression at 48 and/or 72 hr. Nine expression clusters were formed over the entire 72 hr time course and in
