Highly resistant E.Coli produced through gene transfer were subjected to LF 11.

Species: Human

Highly resistant E.Coli produced through gene transfer were subjected to LF 11 and few other antibiotics to assess the antimicrobial activity over the resistant strains.The percentage inhibition over time was determined by disc diffusion and broth dilution methods.
