Silver Nanoparticles Decrease the Viability of Cryptosporidium parvum Oocysts.

Abstract

Oocysts of the waterborne protozoan parasite Cryptosporidium parvum are highly resistant to chlorine disinfection. We show here that both silver nanoparticles (AgNPs) and silver ions significantly decrease oocyst viability, in a dose-dependent manner, between concentrations of 0.005 and 500 μg/ml, as assessed by an excystation assay and the shell/sporozoite… (More)
