PG - 1-6 LID - S1090-0233(15)00439-6 [pii] LID - 10.1016/j.tvjl.2015.10.030 [doi] AB - Porcine respiratory disease is a multifactorial and complex disease caused by a combination of infectious pathogens, environmental stressors, differences in production systems, and various management practices; hence the name porcine respiratory disease complex (PRDC) is used. Porcine circovirus type 2 (PCV2), porcine reproductive and respiratory syndrome virus (PRRSV), and Mycoplasma hyopneumoniae are considered to be the most important pathogens that cause PRDC. Although interactions among the three major respiratory pathogens are well documented, it is also necessary to understand the interaction between vaccines and the three major respiratory pathogens. PRRSV and M. hyopneumoniae are well known to potentiate PCV2-associated lesions; however, PRRSV and mycoplasmal vaccines can both enhance PCV2 viraemia regardless of the effects of the actual PRRSV or M. hyopneumoniae infection. On the other hand, M. hyopneumoniae potentiates the severity of pneumonia induced by PRRSV, and vaccination against M. hyopneumoniae alone is also able to decrease PRRSV viraemia and PRRSV-induced lung lesions in dually infected pigs. This review focuses on (1) interactions between PCV2, PRRSV, and M. hyopneumoniae; and (2) interactions between vaccines and the three major respiratory pathogens.
