a patient has blood infection caused by gram negative bacterial species. why might it be dangerous to treat this infection with fadt acting cidal antibiotic
Homework Answers
Gram negative bacteria are more potent than gram positive bacteria because of their thin peptidoglycon and an airlock layers.This membrane protects it from any external sources trying to destroy it . This layer produces a resistance to the lysozyme and especially penicillin drugs.This can develop resistance and cause serious infection so it dill be dangerous to use fast acting cidal antibiotics .

1. To determine the likelihood that a patient with a bacterial infection who is in the intensive care unit (ICU) of a hospital could be successfully treated with antibiotic therapies, researchers investigated the frequency of antibiotic resistance in bacteria isolated from patients in ICUs in the United States from 1994 to 2000. The data from the study are shown in the table, along with the overall change in the frequency of bacterial resistance in patient samples from 1994 to 2000....
