- Cryptosporidium is a world widely distributed parasite which comparatively has a high prevalence in developing countries. The zoonotic potential of some Cryptosporidium species has made the cryptosporidiosis a significant concern to physicians and veterinarians. The occurrence and zoonotic potential of Cryptosporidium species in probable reservoir hosts for man infections was determined by examining faeces of symptomatic and asymptomatic animals. The aim of this study is to screen the presence of Cryptosporidium in fecal sample of free ranging animals in Tehran using Ziehl–Neelsen staining method. The findings indicate that Cryptosporidium are present in 9/50 (18 %) stray cat (Felis catus), 12/50 (24 %) hooded crows (Corvus cornix), 23/180 (12.7 %) rat (Rattus norvegicus and R. rattus) and 1/40 (2.5 %) pigeons (Columba livia). This investigation confirms the potential role of rats, cats, crows and pigeons for zoonotic transmission of human cryptosporidiosis and they must be considered as reservoir hosts which can endanger public health.
