Article Synopsis
- MRSA (methicillin-resistant Staphylococcus aureus) is a significant cause of hospital infections, and this study investigates how hospital environments contribute to its spread through surface contamination and patient load.
- Over a year, high-contact surfaces in two wards were tested, revealing that 23.7% were contaminated with MRSA; handrails and medicine rooms were the most affected.
- The study found various MRSA strains, but higher clinical cases did not correlate with increased environmental contamination, highlighting the need for regular cleaning of surfaces to reduce MRSA risk.
Background: Little is known about the occurrence and epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) in public transportation in the United States. This research sought to determine the background prevalence and phenotypic and genotypic characteristics of MRSA strains circulating on buses from a large, metropolitan transportation agency.
Methods: Electrostatic wipes were used to collect 237 surface samples from 40 buses randomly selected from July-October 2010.
The role that environmental contamination might play as a reservoir and a possible source of Methicillin-resistant Staphylococcus aureus (MRSA) for patients and personnel at equine veterinary hospitals remains undefined, as the environment has only been monitored during outbreaks or for short periods. Therefore, the objectives of this study were to determine the monthly presence, distribution, and characteristics of environmental MRSA at an equine hospital, and to establish patterns of contamination over time using molecular epidemiological analyses. For this purpose, a yearlong active MRSA surveillance was performed targeting the environment and incoming patients.

- MRSA has become a significant concern in both veterinary and human health, yet there is limited information on how it affects animals, particularly dogs.
- A study at The Ohio State University involved screening 435 dogs for MRSA upon arrival at a veterinary hospital, discovering that 5.7% were MRSA positive, with a notable concentration of infections in the nares and skin lesions.
- Interestingly, the study found that dogs owned by veterinary students had a much higher likelihood of being MRSA positive compared to those owned by clients from other professions, highlighting a potential risk factor related to the veterinary community.
Methicillin-resistant Staphylococcus aureus (MRSA) is known to be present in small animal veterinary clinical environments. However, a better understanding of the ecology and dynamics of MRSA in these environments is necessary for the development of effective infectious disease prevention and control programs. To achieve this goal, a yearlong active MRSA surveillance program was established at The Ohio State University (OSU) Veterinary Medical Center to describe the spatial and molecular epidemiology of this bacterium in the small animal hospital.

The present report is a cross-sectional study to determine the prevalence of MRSA on specific human and animal contact surfaces at a large veterinary hospital during a nonoutbreak period. A total of 156 samples were collected using Swiffers(®) or premoistened swabs from the small animal, equine, and food animal sections.
