Mycoplasma hyosynoviae causes arthritis in pigs older than 12 weeks. The role of colostrum in protection of piglets against M. hyosynoviae infection is not clear. Our objective was therefore to investigate whether transfer of maternal immunity to pig

False-positive serological reactions (FPSR) due to infections with Yersinia enterocolitica serotype O[ratio ]9 (YeO[ratio ]9) are a problem in tests for brucellosis. In the present study, FPSR in classical and novel tests for brucellosis following ex
