title: Microbiology of the canine nasal cavities.
abstract: The microbiota of both nasal cavities were investigated in 37 dogs by both aerobic and anaerobic techniques. The predominant microorganisms were composed of enterococci and staphylococci. A surprisingly high incidence (46%) of Gram-negative rods was noted from the inferior portion of the nose. Microorganisms from the superior region of the nose, as obtained with a surgical approach, differed both qualitatively and quantitatively from the respective transnasal cultures. Thus, it appears that different bacterial populations are present within various anatomic regions of the nose and a routine transnasal culture cannot accurately reflect the microbiology of the entire nasal cavity.
