Abstract:
Although the role of pets in household transmission of meticillin-resistant Staphylococcus aureus (MRSA) has been examined previously, only minor attention has been given to the role of the abiotic household environment independent of, or in combination with, colonisation of pets and human beings to maintain transmission cycles of MRSA within the household. This report reviews published work about household transmission of S aureus and other staphylococci and describes contamination of household environmental surfaces and colonisation of pets and people. Household microbial communities might have a role in transfer of antimicrobial resistance genes and could be reservoirs for recolonisation of people, although additional research is needed regarding strategies for decontamination of household environments. Household-based interventions should be developed to control recurrent S aureus infections in the community, and coordination between medical and veterinary providers could be beneficial.
Insights
The abiotic household environment, alongside pets and people, plays a role in meticillin-resistant Staphylococcus aureus (MRSA) transmission. Further research is needed on environmental decontamination strategies to control MRSA in communities.
Area of Science:
- Microbiology and Public Health
- Environmental Science and Epidemiology
Background:
- Meticillin-resistant Staphylococcus aureus (MRSA) household transmission is a growing concern.
- Previous studies have focused on pets and humans, with limited attention to the abiotic environment.
Purpose of the Study:
- To review the role of the abiotic household environment in MRSA transmission.
- To explore the combined impact of environmental surfaces, pets, and humans on MRSA persistence.
- To identify knowledge gaps in environmental decontamination strategies.
Main Methods:
- Systematic review of published literature on household transmission of Staphylococcus aureus and other staphylococci.
- Analysis of studies detailing environmental surface contamination and pet/human colonization.
- Synthesis of findings regarding microbial communities and antimicrobial resistance gene transfer.
Main Results:
- The abiotic household environment can be contaminated with MRSA, acting as a reservoir.
- Household microbial communities may facilitate antimicrobial resistance gene transfer.
- Pets and humans can be colonized, contributing to MRSA transmission cycles.
Conclusions:
- The abiotic household environment is a significant factor in MRSA transmission dynamics.
- Further research is crucial for developing effective household environmental decontamination strategies.
- Integrated community-based interventions and inter-professional collaboration (medical/veterinary) are recommended.
