Methicillin-resistant <i>Staphylococcus aureus</i> outbreak in a Dutch equine referral clinic.

ABSTRACT: In 2020 and 2022, nine cases of surgical site infections with a methicillin-resistant Staphylococcus aureus (MRSA) were diagnosed in horses in an equine referral clinic. Sixteen isolates (horses, n=9; environment, n=3; and staff members, n=4) were analysed retrospectively using Nanopore whole-genome sequencing to investigate the relatedness of two suspected MRSA outbreaks (2020 and 2022). The MRSA isolates belonged to ST398 and ST612. ST398 genomes from 2020 and 2022 formed three phylogenetic clusters. The first ST398 cluster from 2020 consisted of isolates from five horses and one staff member, and we suspected within clinic transmission. The second cluster of ST398 isolates from 2022 originated from two horses and two staff members but showed higher single nuc
