Abstract: Improving Mycoplasma hyopneumoniae diagnostic capabilities by harnessing the infection dynamics

Mycoplasma hyopneumoniae remains one of the most problematic bacterial pathogens for pig production. Despite an abundance of observational and laboratory testing capabilities for this organism, diagnostic interpretation of test results can be challenging and ambiguous. This is partly explained by the chronic nature of M. hyopneumoniae infection and its tropism for lower respiratory tract epithelium, which affects diagnostic sensitivities associated with sampling location and stage of infection. A thorough knowledge of the available tools for routine M. hyopneumoniae diagnostic testing, together with a detailed understanding of infection dynamics, are essential for optimizing sampling strategies and providing confidence in the diagnostic process. This study reviewed known information on sampling and diagnostic tools for M. hyopneumoniae and summarized literature reports of the dynamics of key infection outcomes, including clinical signs, lung lesions, pathogen detection, and humoral immune responses. The information gathethered in this manuscript can facilitate better understanding of the performance of different diagnostic approaches at various stages of infection with Mycoplasma hyopneumoniae.

Video: Biosecurity Compliance - Dr. Jean-Pierre Vaillancourt

In this episode of The Swine it Podcast Show Canada, Dr. Jean-Pierre Vaillancourt, professor of veterinary medicine at the University of Montreal, discusses the human side of biosecurity compliance. He explains why protocols often fail when people are tired, unconvinced, undertrained, or working with impractical systems, and how leadership, employee input, technology, feedback, and small incentives can make biosecurity more consistent on swine farms. Listen now on all major platforms!

"Biosecurity only works when people repeatedly do the right thing, and that means the system has to support compliance every day."

Meet the guest: Dr. Jean-Pierre Vaillancourt is a veterinarian and professor of veterinary medicine at the University of Montreal. His work focuses on biosecurity, infectious disease control, and practical risk reduction in animal production systems, with experience across swine and poultry health.
