During the export quarantine, 3 of 80 goats, from 16 farms in Nagano Prefecture, died of pneumonia due to infection with Pasteurella haemolytica serotype 2 in March 1985. A serological survey on P. haemolytica (serotype 2) infection was carried out using indirect hemagglutination (IHA) test. The antigen of the IHA was prepared from glutaraldehyde-fixed sheep red blood cell, sensitized with heat extracted antigen of the bacilli.
Sixty-five (81%) of 80 sera from the goats on the second day of quarantine showed 1: 4 or more IHA-antibody titer and the geometric-mean was 10.3. The positive sera were distributed in 15 of 16 farms. When IHA was performed with 9 pair-sera (interval of 14-16 days) in 27 goats which manifested respiratory symptoms, significant increase of the antibody was observed in 3 pair-sera.
