Document Summary
Some antibiotics penetrate the cell wall more than others. Typical uses are for infections caused by strains of multiple drug-resistant pseudomonas aeruginosa or carbapenemase-producing. Enterobacteriaceae: their most common use is in topical creams and ointments. If you go to the drugstore and look at the antiseptic creams in the over-the-counter ailse, you"ll see that many of them contain polymixin. More and more often, we are advising people not to use antibiotic creams and ointments unless they absolutely need them. Often you can tell they simply looking at the infection. In some cases, specific bacterial infections have a unique odor and a good diagnostician can determine what the bacteria is simply by smelling: other bacteria are considerably less unique. Certain infections need to be confirmed before you can treat them. You may suspect it"s a certain kind of bacteria, but until you have a culture, it"s not clear. The laboratory uses the kirby-bauer disc diffusion test to determine which antibiotic work.
