Prolonged Use of Herbicides Increased the Resistance of Soil Aerobic Heterotrophic Bacteria and Fungi to Antibiotics

Increase in the use of herbicides agricultural soil can cause multiple antibiotic resistance potential pathogens that undermine therapy. The study shows antimicrobial susceptibility aerobic heterotrophic bacteria and fungi isolated from soils polluted with different herbicides. A total sixteen (16) bacterial twenty-three (23) fungal isolates were subjected to sensitivity test (AST) using Kirby-Bauer disc diffusion method. Both Gram positive Gram-negative antibacterial agents used for bacteria, a four antifungal fungi. result showed higher especially where two (paraquat glyphosate) combined compared control without history usage.This work demonstrates prolonged usage increased rate at which acquire resistance.
