title: Development of a new serological test for serotyping Haemophilus parasuis isolates and determination of their prevalence in North America.
abstract: Haemophilus parasuis causes polyserositis in swine. Fifteen serovars have been characterized by immunodiffusion test, but many field strains are not typeable. Isolates (n = 300) of H. parasuis from animals in North America were serotyped by a new indirect hemagglutination test. The test was rapid and effective for serotyping of H. parasuis, and serovars 4, 5, 13, and 7 were the most prevalent serotypes.
