Effect of sodium hypochlorite exposure on infectivity of Cryptosporidium parvum oocysts for neonatal BALB/c mice

Abstract

Oocysts of Cryptosporidium parvum suspended in 5.25, 2.63, or 1.31% aqueous sodium hypochlorite (Clorox laundry bleach) for 10, 30, 60, or 120 rain at 21°C were administered by gastric intubation to neonatal BALB/c mice. Microscopic examination of intestinal tissue sections revealed developmental stages of C. parvum in all of the mice.
