AB  - The ability of nine reference strains of <I>Ornithobacterium rhinotracheale</I> (serovars A-I) to raise detectable, hemagglutination-inhibition antibodies in immunized specific-pathogen-free chickens was investigated. Six of the nine <I>O. rhinotracheale</I> serovar (A-H) reference strains raised detectable hemagglutination-inhibition antibodies 14 and 21 days after vaccination. Detectable serum hemagglutination-inhibition antibody titers ranged from 512-16348. Furthermore, transmission electron microscopic examination of a hemagglutinating reference strain (B 3263/91, serovar A) demonstrated a close interaction between the bacterial and chicken erythrocyte surfaces. The results indicate that most of the hemagglutinating <I>O. rhinotracheale</I> reference strains included in this study are able to raised detectable hemagglutination-inhibition antibodies in immunized specific-pathogen-free chickens. The findings have the potential to become an alternative laboratory approach for detecting serum antibodies from chickens immunized with <I>O. rhinotracheale</I>.
