N2 - Ninety-five isolates of Haemophilus paragallinarum were classified serologically by a hemagglutinin serotyping scheme, and the results were compared with results from agglutinin serotyping of the same isolates. Of the isolates, 65 were from Australia, 5 were from Japan, 6 were from the Federal Republic of Germany, 7 were from the United States, and 12 were from South Africa. Seven hemagglutinin serovars, HA-1 to HA-7, corresponding to agglutinin serovars A (HA-1, HA-2, and HA-3), C (HA-4, HA-5, and HA-6), and B (HA-7) have been described. Only one of the seven hemagglutinin serovars was found among the Australian isolates. This was serovar HA-5, comprising 49 isolates. Fifteen Australian isolates, all from Southeast Queensland and northern New South Wales, were found to belong to a new hemagglutinin serovar. This was designated HA-8 and represented a fourth subgroup of agglutinin serovar A. Of the 95 isolates examined, only 1 did not produce a hemagglutinating antigen and was nonserotypeable by the hemagglutinin system. This compared favorably with the agglutinin scheme, which serotyped only 60 of the 95 isolates, with 29 nonserotypeable and 6 autoagglutinating.
