A total of 455 domestic animals (cow, horse and camel) and poultry from south of Iran were surveyed for fecal carriage of Campylobacter spp. Out of all collected fecal samples, the highest isolation rate of Campylobacter was recorded among poultry (35%), followed by horse (27%) and cow (21%) while, lowest isolation rate was recorded among camel. Of the 85 Campylobacter strains isolated, 76 were classified as catalase positive Campylobacter. Out of them, high frequency of occurrence was belonged to Campy. jejuni. Furthermore, catalase positive Campylobacter spp. were isolated from all the sources of investigation, other than camel. The results obtained from biotyping of the isolates indicated Camp. lari biotype I followed by Camp. jejuni and Camp. coli biotypes I existed in high frequency; while Camp. jejuni biotype II and untypable Campylobacter existed in low frequency. Overall, domestic animals and poultry other than camels are vehicle of Campylobacter in the area of investigation therefore, the people who living in this area may be infected via feces of domestic animals and poultry.
