An Infected Dog Bite With Neisseria canis: A Case Report and Review of the Literature.

Neisseria is a common bacteria that colonizes in humans. Of the 11 species, only two, N. meningitidis and N. gonorrhea, are pathogenic. Although sparse, there are case reports of other Neisseria species causing infections in humans. Neisseria canis, which is a part of normal flora in the mouths of dogs and cats, has been shown to have potential to be pathogenic in humans. The standard treatment for dog and cat bites is oral amoxicillin/clavulanic acid (Augmentin) or IV ampicillin/sulbactam (Unasyn). However, in cases where the patient has multiple antibiotic allergies, careful antibiotic selection must be made to ensure resolution of infection.
