Abstract
The presence of Arcobacter spp. in 2 breeding hen flocks was determined by examination of the intestinal tract, oviduct magnum mucosa, and ovarian follicles of slaughtered chicken. The bacteria were detected by PCR and cultural isolation in 34 out of 40 intestinal tracts from one flock (A) and 6 out of 30 from the other (B). The strains were Arcobacter butzleri, Arcobacter cryaerophilus, and Arcobacter skirrowii. From flock A, arcobacters were recovered from 6 out of 40 oviduct magnum mucosa samples. The majority of isolated strains were A. butzleri. Arcobacter spp. could not be detected, by either PCR or isolation, from 20 eggs collected on the farm of flock A and from 20 eggs still remaining in the vagina of hens in flock B. Furthermore, none of the ovarian follicles from each flock were positive. The results indicate that breeding hens can be infected with Arcobacter spp. in the intestinal tract and oviduct. No evidence was obtained for transmission of Arcobacter spp. from hens to eggs.
