Full Description
The goal of this project was to determine the occurrence of the N. fowleri in well water. Thepresence of Naegleria fowleri was confirmed in 8.3% of the wells sampled. Re-testing of asubset of wells suggests that some wells are colonized by the organism. Laboratory experimentswith N. fowleri cysts and trophozoites indicate that the Ct (concentration of disinfectant X time)for free chlorine is 6 for the trophozoite form and 31 for the cysts at 23 C. These Ct values forN. fowleri cysts were comparable to published values for Giardia cysts but much greater thanthose for Cryptosporidium oocysts. Includes 26 references.Cart
