Seasonal variation in prevalence of different respiratory pathogens during post-weaning and fattening period in Belgian and Dutch pig herds using a tracheo-bronchial swab technique

摘要

Besides Mycoplasma hyopneumoniae (M. hyo), many other viruses and bacteria can be present, provoking the disease complex known as PRDC. Recently, a new sampling technique has been developed and validated for the detection of M. hyo in pigs using PCR,namely the tracheobronchial swab (TBS) technique. The aim of the present study was to obtain data on the variation in distribution of different pathogens involved in PRDC in closed pig herds in Belgium and the Netherlands using the TBS technique during the different seasons of the year.
