High levels of antibiotic resistance genes and opportunistic pathogenic bacteria indicators in urban wild bird feces

High levels of antibiotic resistance genes and opportunistic pathogenic bacteria indicators in urban wild bird feces

The global threat of antimicrobial resistance can be contained only through the ‘One health’ approach. This approach basically states that the human, animal and environmental health is interconnected and the efforts to tackle ABR should be taken at all the three levels. Hence, in-depth understanding of the several routes of spread of the antibiotic resistance among human, animal and environment will certainly assist to effectively limit spread of antibiotic resistance. A study led by Dr. Pingfeng Yu, a post-doctoral researcher at Rice University, Texas, USA is an excellent contribution in the similar line. The study revealed that urban bird droppings are key players in the spread of the antibiotic resistance via dissemination of the antibiotic resistance genes (ARGs) and virulence genes in the environment. The study showed abundance of resistance genes-tetracyclines (tetW), β-lactams (bla TEM ), and sulfonamides (sul1), mobile genetic elements (intI1), antibiotic resistant bacteria (i.e., Enterococcus spp. and Pseudomonas aeruginosa) in the urban bird feces. In brief, study highlights contribution of the bird feces in the spread of antimicrobial resistance, raises awareness to avoid direct contact with the feces and suggests that regular cleanliness will help in reducing associated risk.
