Healthcare-associated infections (HAIs) are often overlooked in veterinary medicine. Serratia marcescens isolates were recovered over a ten-year period from companion animals in a French veterinary hospital. The pets were sampled either for diagnostic purposes or to monitor colonization. A retrospective study showed that 32 S. marcescens isolates were identified as HAI cases and a further 22 cases were associated with colonization of the surgical site. Two S. marcescens lineages were responsible for two different outbreaks during the study period. Chlorhexidine solution (1%) used to impregnate gauze was found to be the source of the second S. marcescens outbreak and all isolates had high MIC values for chlorhexidine (MIC = 128 mg/L). This study reports, for the first time to our knowledge, the nosocomial spread of chlorhexidine-resistant S. marcescens in a veterinary setting and highlights consequences of the improper use of disinfectants.
