Farm-originated Antimicrobial Resistance Modeling: Exploring Humans-to-Animal Dissemination (FARMHAND)

Farm-originated Antimicrobial Resistance Modeling: Exploring Humans-to-Animal Dissemination - FARMHAND

Antimicrobial resistance is a major public health issue. Methicillin resistance in Staphylococcus aureus (MRSA) is one of the indicators that is monitored particularly closely. In animals, pig farms, among others, have been identified as reservoirs of MRSA, with a risk of transmission to humans, particularly to individuals in direct contact with livestock. In France, the prevalence of MRSA in pig farms has increased markedly in recent years.

While cross-species transmission between pigs and humans in professional settings is well-documented, the temporal dynamics, the actual incidence of acquisition, and the associated determinants remain insufficiently characterized in France.

Adopting a "One Health" approach, this project aims to gain a better understanding of the mechanisms by which MRSA spreads between animal and human subpopulations and to incorporate these insights into a mathematical modeling framework.

Detaljert beskrivelse

The participants in this project will be farmers representing 20 different pig farms, the majority of which will be located in Brittany-a region recognized as the leading pork-producing area in France.

Participants will be asked to provide two types of samples, only one of which will contain personally identifiable data.

  • Nasal swabs: Participants in the study will be asked to perform a self-administered nasal swab once a month, at approximately the same time each month. This method was selected because it has demonstrated an acceptable level of participant compliance, as well as satisfactory validity for detecting S. aureus carriage in humans.
  • Dust samples: Participants will be asked to collect dust samples from the production floor-specifically in the room within the finishing facility that houses the oldest animals-by wiping surfaces with a small cloth. This method was chosen because dust in livestock-rearing environments has been identified as a reliable indicator of MRSA carriage status in pigs.

These successive samplings will be carried out over time in order to analyze carriage dynamics and estimate epidemiological parameters of interest. A modeling component will be incorporated to make use of the data collected.
