Description
Ibrahim M. Alzuheir leads a five-author team reporting a 2026 cross-sectional study of MRSA carriage among people who work with dairy cattle in Jordan. Nasal swabs came from 100 cattle-exposed individuals and 100 non-exposed controls. The team identified Staphylococcus aureus by a gene test for nuc and confirmed methicillin resistance via the mecA gene. Multiplex tests screened the isolates for drug resistance, toxin, biofilm, and immune evasion genes.
S. aureus grew from 41.0 percent of all swabs, and 76.8 percent of those isolates were MRSA, split almost evenly between the two groups. The resistance gene blaZ appeared in every exposed-group isolate, and biofilm genes icaA and icaD were universal. Several virulence genes differed significantly: selr, hlg, and etd were commoner in exposed isolates, and etd appeared only there, in 50 percent of cases. The authors call for ongoing molecular surveillance at the livestock-human boundary.
