Ahmed ZK, Abbas AK., Prevalence of cryptosporidium in domestic and stray cats in Baghdad, Iraq, Onl J Vet Res., 22 (8):715-720, 2018. Authors report prevalence of Cryptosporidium in feces of 60 domestic and stray cats from Baghdad, Iraq by microscopy (n=120) and PCR (N=100). By microscopy we found 9.6% and by PCR 20% infected by Cryptosporidium parvum with 9.6% of domestic female and 9.3% male strays. Domestic male cats were not infected. We found no difference between domestic and stray kittens or adults but possibly higher prevalence in warmer months. One PCR primer was used in this study for detection of Cryptosporidium using complete sequence 18 ribosomal gene (Hadfield et al., 2011). The higher values by PCR may be due to detection of remnant DNA from past infections.
