No conflicts of interest reported. Bordetella bronchiseptica (Bb) is one of the primary causative agents of canine infectious respiratory disease (CIRD). This contagious disease, commonly seen in young dogs, is often self-limiting, although a wide range of respiratory signs can be found, from mild illness to severe pneumonia leading to death. Although Mycoplasma cynos (M. cynos) was recently identified as an emerging and possibly lethal pathogen in CIRD 1 , the role of M. canis and M. cynos as primary respiratory pathogens still remains unclear. Detection of these bacteria is now improved by quantitative polymerase chain reaction (qPCR). In dogs with CIRD due to Bb, the frequency of co-infection with Mycoplasma spp, in par-ticularM. cynos, and their possible role in the severity of the clinical signs are unknown.
