FAQ: What Type Of Bacteria Does Neomycin Antibiotic Target?


What bacteria does neomycin cover?

Neomycin has activity against many aerobic gram negative and gram positive bacteria, including the major E. coli species resident in the colon as well as the enteropathogenic forms of E. coli known to cause traveler’s diarrhea. Like other aminoglycosides, neomycin is poorly absorbed orally.

Is E coli resistant to neomycin?

Irrespective of the year, less than 15% E. coli isolates were resistant to apramycin, cephalosporins, colistin, enrofloxacin, florfenicol, gentamicin and neomycin.

What is the specific molecular target of neomycin?

Neomycin irreversibly binds to the 16S rRNA and S12 protein of the bacterial 30S ribosomal subunit. As a result, this agent interferes with the assembly of initiation complex between mRNA and the bacterial ribosome, thereby inhibiting the initiation of protein synthesis.
