WebNeomycin has activity against most gram-negative aerobes, and inhibits protein synthesis via binding to the 30S ribosomal unit. Although the mechanism of action for HE is assumed to be its antibiotic action, there is also evidence of villous atrophy, resulting in inhibition of intestinal glutaminase. derrick hardy facebookThe oxygen sensitivity of obligate anaerobes has been attributed to a combination of factors including oxidative stress and enzyme production. Oxygen can also damage obligate anaerobes in ways not involving oxidative stress.
