Additionally, Mr. Shahbazian said that 100 percent of MRSA isolates the investigators obtained from rural homes were multidrug resistant, "suggesting living in a rural household may be a risk factor for multidrug resistance."
"We also found the presence of domestic pets was associated with multidrug resistant MRSA in the home environment, while the presence of unwanted pests, such as mice or cockroaches, was associated with non-multidrug resistant MRSA strains," said Mr. Shahbazian.
