antibiotic discovery

When it comes to antibiotic research, what does the word "innovation" mean? It's a bit different for antibiotics. Dr. David Shlaes argues that a difference in clinical utility is a better measure, even when a new drug or combination of drugs may be structurally similar to older drugs. This, from his blog "Antibiotics, the Perfect Storm."
Antibiotic resistance is spotty. If you are hospitalized in New York and you acquire a Gram-negative infection in the hospital, there is a reasonable chance it will be caused by a highly resistant pathogen. If you go to a hospital in New Hampshire or Vermont, there is almost no chance for that to happen. ACSH advisor Dr. David Shlaes explains.
