We are studying M. hyopneumoniae, M. hyorhinis and M. hyosynoviae. We perform genomic research and develop novel genotyping methods (Földi et al., 2020). We determine the antibiotic susceptibility profiles (MIC) of isolates (Klein et al., 2022), identify the genetic markers of resistance (Felde et al., 2018) and develop rapid and cost-effective assays for their detection (Felde et al., 2020). We also work on vaccine development projects.
