    This study was performed to determine the prevalence and molecular characterization of Cryptosporidium in ostriches on a farm in Khanh Hoa province, central Vietnam. A total of 464 ostrich fecal samples were examined Cryptosporidium oocysts using the modified Ziehl-Neelsen staining method, and 110 (overall prevalence 23.7%) were identified as positive by microscopy. Prevalence of Cryptosporidium in animals of <45. days, 45-60. days, 61-90. days, 91. days-12. months and >12. months was 23.5% (16/68), 33.3% (22/66), 35.2% (68/193), 0 and 5.8% (4/69), respectively (p<. 0.05). The majority of positive samples scored as the 3+ level of intensity of infection were from 61 to 90. days ostriches. Molecular analysis in the 18S ribosomal RNA, 70. kDa heat shock protein and actin genes demonstrated the presence of only Cryptosporidium avian genotype II in ostriches in central Vietnam.
