| Abstract: | Gross postmortem pathologic-anatomical and bacteriological examination, and serotyping for Haemophilus parasuis were performed in 401 weaned pigs with the clinical symptoms of Gl?sser's disease, originating from indoor (204 piglets out of 12 units) and outdoor (197 piglets out of 9 units) units in the country triangle Hungary/Romania/Serbia. The majority of the isolates in indoor units included Haemophilus parasuis serotypes 2, 5 and non typable, while in outdoor units, a high diversity (serotypes 1, 2, 4, 5, 11, 12, 14, 15, and non typable) of Haemophilus parasuis serotypes was found. |
