Haemophilus parasuis is the etiological agent of Glässer's disease, often involved in pneumonia, and also an early colonizer of the upper respiratory tract of healthy domestic pigs. Little information is available on H. parasuis in wild boars. The aim of the present study was to evaluate H. parasuis infection in wild boars in Germany. Tissue samples from the lungs and tonsils of 531 wild boars from 52 hunts during the hunting seasons 2004/2005 to 2006/2007 were examined independently for H. parasuis by PCR because H. parasuis is a fastidious organism, which hampers its isolation from clinical samples. The overall prevalence of H. parasuis in wild boars in Germany was 74.2%. H. parasuis was detected in 69.1% of tonsils and 40.4% of lungs. In conclusion, the present study demonstrates a wide distribution of H. parasuis in German wild boar populations and further research is required to understand the virulence of H. parasuis strains in wild boars, as well as the distribution and potential exchange of different strains between wild boars and domestic pigs.
