Abstract

We compared serological responses to Cryptosporidium parvum antigens using surplus sera from females undergoing routine screening for pregnancy from three counties in Hungary where bank-filtered surface water, conventionally filtered and disinfected surface water, and groundwater from either a karst or confined aquifer are commonly used for drinking water. The primary purpose was to determine whether the prevalence and intensity of serological responses, indicators of prior Cryptosporidium infection were similar for these populations. Women using groundwater from a confined aquifer had significantly lower mean serological responses for both the 15/17-kDa and 27-kDa (p <0.0001) antigen groups than women using conventionally filtered and disinfected surface water or karst well water. This is suggestive of less frequent infections. Women using bank-filtered water also had lower mean responses for both antigen groups. Among women using bank-filtered water, the mean intensity of response for both antigen groups was almost one-third of the mean response observed for women using conventionally filtered and disinfected surface water. These findings suggest that riverbank filtration may be an effective alternative to conventional treatment for reducing Cryptosporidium exposures and infection from surface drinking water sources.
