Mycoplasma hyopneumoniae causes lung infections characterised by a low mortality, but high morbidity. This results in a higher FCR, lower daily growth, higher risk for secondary infections and increased treatment costs. Although M. hyo has been the topic of much research, its pathogenesis is still not completely clear, immune responses after infection and vaccination need to be further investigated. In this podcast host Vincent ter Beek of Pig Progress discusses the PhD study of Dr Evelien Biebaut, attached to Ghent University in Belgium, who spared no effort to learn more about how the bacteria behaves and how it can be controlled. Dr. Biebaut will tell you all about it.
