Dirt Floors and Domestic Animals Are Associated with Soilborne Exposure to Antimicrobial-Resistant <i>E. coli</i> in Rural Bangladeshi Households.

ABSTRACT: Soil can harbor enteropathogens and antimicrobial-resistant organisms from domestic animals. We enrolled 49 households with young children (28 soil floors and 21 concrete floors) in Bangladesh and recorded animal ownership/management. Staff swabbed the floor of children's sleeping area and collected floor dust and child hand rinses. We used IDEXX QuantiTray/2000 with and without cefotaxime supplementation to enumerate cefotaxime-resistant and generic E. coli. Soil floors had 40 times more dust than concrete (8.0 vs 0.2 g/m², p-value = 0.005). We detected E. coli on 100% of soil vs 86% of concrete floors and cefotaxime-resistant E. coli on 89% of soil vs 43% of concrete floors (p-values <0.05). Cefotaxime-resistant E. coli prevalence on f
