Incidence of campylobacters in the intestine of avian species in Alabama

Avian Dis. 1995 Jan-Mar;39(1):147-51.

Abstract

Avian species necropsied at the C. S. Roberts Veterinary Diagnostic Laboratory, Auburn, Alabama, from December 1993 until May 1994 were examined for the incidence of intestinal campylobacters. Ninety-one intestinal swabs, representing 66 separate cases and 17 different avian species, were collected and placed into Cary-Blair transport medium. Selective enrichment and culture media were used for initial isolation of Campylobacter spp. Presumptive colonies were identified as Campylobacter spp. by phase-contrast microscopy and Gram stain, and they were confirmed by serological latex agglutination. Campylobacter spp. were isolated in 18 (19.7%) of the 66 cases. From the remainder of the cases, 13 (15%) yielded presumptive colonies on Campy-Cefex agar; however, they were not confirmed serologically as Campylobacter spp. Use of Cary-Blair transport medium held in refrigeration for up to 24 days did not hinder the determination of campylobacters in intestinal samples. A variety of avian species, including chicken, emu, hawk, ostrich, and parrot, harbored commensal campylobacters and therefore should be considered potential reservoirs.
