During the period January 2004 to December 2005 four different ostrich farms were investigated to evaluate the presence of thermotolerant Campylobacter. A total of 150 ostriches were examined and all were found to be clinically healthy. Campylobacter spp. were isolated from 60/150 cloacal swabs. Among the isolates, 48 were identified as Campylobacter jejuni whereas the remainder were identified as Campylobacter coli. Campylobacter lari was not isolated. The ostriches, although apparently in a healthy body condition, can be considered, theoretically, as potential Campylobacter carriers.
