Isolation of Arcobacter spp. and identification of isolates by multiplex PCR from various domestic poultry and wild avian species

The purpose of the present study was to determine the extent and seasonal prevalence of Arcobacter spp. in domestic poultry and wild birds in the Kars region of Turkey using multiplex polymerase chain reaction (m-PCR). In this study, 1570 samples were collected from domestic poultry and wild avian species. The numbers of collected samples were as follows: 182 fecal samples from chickens, geese, and turkeys from family farms in the Kars region in Turkey; 1089 cloacal swab samples from chickens, geese, ducks, turkeys, and quails from family farms in this region; and 299 fecal samples from wild pigeons, crows, and owls in the same region. Arcobacter spp. were isolated from 17.43%, 35.77%, 3.63%, 6.87%, and 3.33% of the cloacal swab samples obtained from geese, ducks, chickens, turkeys, and quails, respectively. In the stool samples, Arcobacter spp. were isolated from 9.62%, 13.33%, and 4% of chicken, goose, and turkey samples, respectively. In wild birds, the isolation rates of Arcobacter spp. were 6.6%, 12.15%, and 0% in pigeons, crows, and owls, respectively. Using m-PCR, among 171 Arcobacter spp. isolates obtained from poultry and wild birds, 67, 78, 24, and 2 were identified as Arcobacter cryaerophilus, Arcobacter butzleri, Arcobacter skirrowii, and Arcobacter cibarius, respectively. Both poultry and wild avian species exhibited variable rates of Arcobacter species positivity. The presence of Arcobacter spp. in the digestive tracts of healthy poultry and wild birds may serve as a potential reservoir for the dissemination of these microbes in the environment and their transmission to other animals and humans.
