Comparison of bacterial culture results obtained from three different sampling locations in dogs and cats with chronic nasal disease.

This study indicates that bacterial culture results in feline and canine nasal disease are site-specific and there was no evidence from this study for consistency between sites within a patient for many bacterial species. Consequently, if bacterial culture results from nasal swabs are used to guide therapeutic antimicrobial choice, different treatments may be selected depending on the site of culture. As a consequence, there is no evidence from this study that nasal bacterial cultures should be recommended as a routine diagnostic measure.
