One and two Cryptosporidium-positive isolates were obtained in horses by microscopy and by PCR, respectively. The two C. andersoni isolates. SIR, – We read with interest the findings of Moriarty and others (VR, February 5, , vol , pp ) concerning the prevalence of Cryptosporidium. The difference in the duration of diarrhea of C. andersoni and C. hominis indicated that different Cryptosporidium species might cause different.
