title: Microbiology of the canine nasal cavities.
abstract: The anterior and superior regions of canine nares yielded two distinct microbial populations consisting of 25 microbial species. Streptococci predominated in the anterior nose; clostridia and staphylococci were also quite prevalent. At least two distinct microorgranisms were cultured from most anterior sites. In contrast, sterile conditions prevailed in the superior nasal regions of at least 50% of the ninety-two animals. Various Bacillus sp. were recovered from the remainder.
