Abstract

Abstract
MRSP is a multidrug-resistant, zoonotic canine pathogen. This study investigated MRSP carriage and clearance through topical antimicrobial therapy and household cleaning in dogs recovered from MRSP infection.
Dogs were swabbed for MRSP carriage; household contamination was assessed using contact plates. Carrier dogs were allocated randomly to receive topical fusidic acid and chlorhexidine/miconazole treatment combined with owners implementing a household hygiene protocol (H&T) or implementation of hygiene alone (H) over three weeks. Carriage-negative dogs were monitored monthly. Relatedness of isolates over time was investigated by PFGE.
At inclusion, MRSP carriage was confirmed in 31/46 (67.4%) index dogs, 16/24 (66.7%) contact dogs and contamination was found in 18/40 (45%) environments. In dogs completing all cycles, interventions cleared carriage in 5/9 (55.6%) dogs in group H&T and 2/6 (33.3%) in group H. Carriage frequency reduced with topical antimicrobial treatment and hygiene (P
