Drivers of Antibiotic Resistance Transmissionin Low- and Middle-Income Countriesfrom a "One Health" Perspective-A Review.

Antibiotic resistance is an ecosystem problem threatening the interrelated human-animalenvironmenthealth under the "One Health" framework. Resistant bacteria arising in onegeographical area can spread via cross-reservoir transmission to other areas worldwide either bydirect exposure or through the food chain and the environment. Drivers of antibiotic resistance arecomplex and multi-sectoral particularly in Lower- and Middle-income countries. These includeinappropriate socio-ecological behaviors; poverty; overcrowding; lack of surveillance systems; foodsupply chain safety issues; highly contaminated waste effluents; and loose rules and regulations. Inorder to examine the drivers of antibiotic resistance from a "one health" perspective, a literaturereview was conducted on three databases including PubMed, Medline and Google Scholar. A totalof 485 studies of potential relevance were selected, out of which 182 were included in this review.Results have shown that the aforementioned market failures are the leading cause for the negativeexternality of antibiotic resistance that extends in scope from the individual to the global ecosystem.Incremental and sustainable global actions can make the change, however, the problem willcontinue to prevail if governments do not prioritize the "One health" approach and if individual'saccountability is still denied in a world struggling with profound socio-economic problems.
