Of the 2,546 paired swabs, 47% had cultivable biomaterial and 42% had PCR-amplifiable DNA. The ratios of TOs detected to surfaces assayed were 85 per 1,273 for the culture-based method and 106 per 1,273 for the PCR-based method. Sinks, toilet rails, and bedside tables most frequently harbored biomaterial. Although cleaned surfaces were less likely to have cultivable TOs than precleaned surfaces, they were not less likely to harbor bacterial DNA. The rate of MDR-TOs to surfaces swabbed was 0.1% (3\/2546). Although environmental MDR-TOs and MDR-TOs from HAIs were genetically related by PFGE, WGS revealed that they were unrelated. Environmental levels of cultivable <jats:italic>Enterococcus<\/jats:italic> spp. and <jats:italic>E. coli<\/jats:italic> DNA were positively correlated with infection incidences (P&amp;lt;.04 and P&amp;lt;.005, respectively).<\/jats:p>\n            <\/jats:sec>\n            <jats:sec id=\"S0899823X15001518_abs4\" sec-type=\"conclusion\">\n               <jats:title>CONCLUSION<\/jats:title>\n               <jats:p>MDR-TOs were rarely detected during surveillance and were not implicated in HAIs.
