How do Cryptosporidium oocysts survive outside hosts?
Oocyst transcriptomes reveal metabolic features that help Cryptosporidium parvum endure environmental stresses without nutrient supply.
Source
Transcriptome analysis reveals unique metabolic features in the Cryptosporidium parvum Oocysts associated with environmental survival and stresses
What they did
Profiled C. parvum oocyst transcriptomes to infer metabolic capacity related to environmental persistence.
What they found
Unique metabolic features linked to surviving without nutrients and resisting environmental stresses; oocyst wall protects four sporozoites.
The limits
What it doesn't show
Does not itself invent a new clinical drug regimen.
