Plain-English summary
A group of 13 dogs with gum disease (periodontal disease) had their mouth bacteria tested to see how well they responded to common antibiotics. The study found that many bacteria were resistant to antibiotics, but some, like Bacteroides fragilis, were resistant to all the antibiotics tested. However, the bacteria that caused gum disease were generally susceptible to treatments like amoxicillin combined with clavulanic acid, doxycycline, and erythromycin. This means that these antibiotics could be effective options for treating infections related to periodontal disease in dogs.

Abstract
The aim of the present investigation was to evaluate the subgingival aerobic and anaerobic flora of 13 dogs with periodontal disease and the susceptibility of these bacteria to antibiotics currently approved in Italy for treatment of canine infections. Of the anaerobic bacteria, Bacteroides fragilis was most frequently isolated, followed by Peptostreptococcus + Porphyromonas gingivalis and Prevotella intermedia. Of the aerobic bacteria, alpha-hemolytic Streptococcus was most frequently isolated, often associated with Escherichia coli or Pasteurella multocida. Resistance of anaerobic and aerobic bacteria to various antibiotics was generally high. Anaerobic bacteria appeared to be susceptible to amoxicillin + clavulanic acid, doxycycline, and erythromycin; aerobic bacteria appeared to be susceptible to amoxicillin + clavulanic acid, erythromycin, gentamycin, and sulfa-trimethoprim. Bacteroides fragilis was resistant to all of the antibiotics tested. The emerging worldwide problem of bacterial resistance to antibiotics resulting from overuse and misuse of antibiotics is discussed.
