Reduced antimicrobial prescribing during autogenous staphylococcal bacterin therapy: a retrospective study in dogs with pyoderma.

Autogenous staphylococcal bacterins are commonly mentioned as treatment for canine recurrent pyoderma but little is known about their efficacy. This retrospective study describes use and assesses efficacy of an autogenous Staphylococcus (pseud)intermedius bacterin in dogs with pyoderma. Frequency and duration of systemic antimicrobial therapy were compared 12 months before and after starting bacterin (Wilcoxon signed-rank test) with data extracted from general practice medical histories.
