Identification of Campylobacter jejuni in Macaca fascicularis imported from Indonesia

Campylobacter jejuni was selectively cultured in 33 (66%) of 50 Macaca fascicularis that had been imported from Indonesia. As there was no published information on the incidence of Campylobacter infection in nonhuman primates from Indonesia, a survey was conducted to determine the presence and incidence of Campylobacter jejuni in 50 macaques before they were exported from Indonesia. The organism was positively identified in 18 (36%) of the specimens examined. Repeat cultures after importation and during the quarantine period produced 37 of 48 (77%) positive results. Stool cultures from 57 other Macaca fascicularis and Macaca nemestrina in more preliminary stages of captivity in Indonesia produced only two positive identifications. These findings suggest that Campylobacter jejuni is not a natural pathogen of macaques in Indonesia, but it infects them after capture.
