Abstract

ABSTRACT Cryptosporidium isolates from diarrheic foals in New Zealand ( n = 9) were identified as C. parvum , subtyped at two polymorphic loci, and compared with human ( n = 45) and bovine ( n = 8) isolates. Foal C. parvum isolates were genetically diverse, markedly similar to human and bovine isolates, and carried GP60 IIaA18G3R1 alleles, indicating a zoonotic potential.
