Abstract:
:An improved approach for simultaneous detection of Cryptosporidium parvum and Giardia lamblia (oo)cysts in soil is described. Recoveries>70% were obtained for concentrations>55 and 21 (oo)cysts g(-1) for C. parvum and G. lamblia, respectively. The limits of detection were determined to be<5 (oo)cysts g(-1) soil.
