Methicillin-resistant outbreak in a Dutch equine referral clinic.

In 2020 and 2022, nine cases of surgical site infections with a methicillin-resistant (MRSA) were diagnosed in horses in an equine referral clinic. Sixteen isolates (horses, =9; environment, =3; and staff members, =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.

SARS-CoV-2 infection in dogs and cats is associated with contact to COVID-19-positive household members.

Several domestic and wild animal species are susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Reported (sero)prevalence in dogs and cats vary largely depending on the target population, test characteristics, geographical location and time period. This research assessed the prevalence of SARS-CoV-2-positive cats and dogs (PCR- and/or antibody positive) in two different populations.
