studies in four locations along Kerala coast, have found acrylflavine, fluoroquinolone, beta-lactamase and methilicin resistant genes in microbial populations in mangrove ecological systems. The genes having resistance to antibiotics have been found both in pristine environmental sites and regions affected by human activities.
Dr. Ranjit Kumavath, senior assistant professor, Department of Genomic Science at Kerala Central University, and a key member of the research team, told that “there could be serious consequences if antibiotic resistant genes move from the harmless microbes to pathogens. Further study is currently being designed to evaluate such disseminations. The widespread existence of antibiotic-resistant genes is a warning bell as it is indicating a new source of antimicrobial resistance”.The study included metagenomic profiles of mangrove sediment samples. In order to identify the microbes, next-generation sequencing techniques were used by which one can identify millions of micro-organisms easily and rapidly without the need to grow any microbes in the laboratory.
