Identification and serotyping of Haemophilus pleuropneumoniae by coagglutination test.
A coagglutination test for the identification and serotyping of Haemophilus pleuropneumoniae is described. A total of 360 H. pleuropneumoniae strains were isolated from pulmonary tissues of feeder pigs which died of acute pleuropneumonia. All of the isolates were serotyped by coagglutination, and the results were confirmed by the ring precipitation test. The most common serotype isolated in Que...
متن کاملDetection of type-specific antigens in the lungs of Haemophilus pleuropneumoniae-infected pigs by coagglutination test.
Specific diagnosis of Haemophilus pleuropneumoniae infection by the conventional culture and identification method usually requires 3 to 4 days. Since H. pleuropneumoniae may be disseminated from infected individuals during this period, this amount of time required for diagnosis may be too slow to aid in epidemic control. To obtain an earlier diagnosis, a coagglutination test was successfully u...
متن کاملSerotyping of Streptococcus pneumoniae strains by coagglutination.
The coagglutination test, which uses staphylococcal protein A, for serotyping strains of Streptococcus pneumoniae, was extended to include serotyping within serogroups. Serotyping was performed with "factor sera" prepared in the laboratory. Fifty one strains of S pneumoniae, which belonged to one of the seven serogroups included in the 14 valent vaccine formulation, were tested, and no inconsis...

متن کاملValue of indirect hemagglutination and coagglutination tests for serotyping Haemophilus parasuis.
An indirect hemagglutination test (IHA) and a coagglutination test (CA) were evaluated using saline, boiled, and autoclaved extracts for serotyping Haemophilus parasuis. CA showed several cross-reactions, whereas IHA gave rise to specific reactions, with minor exceptions. IHA was further compared with the immunodiffusion test (the "gold standard") for the serotyping of 67 field isolates. As a c...
