Study shows antibiotic-resistant bacteria responsible for increase in muscle infections

...ave been treated by inexpensive antibiotics in the penicillin and cephalosporin family. Some years ago, strains resistant to these drugs, called methicillin-resistant Staphylococcus aureus (MRSA) appeared in hospitalized patients.

Cloning techniques produce FDA-approved antibiotic

...ions that have become resistant to the antibiotics penicillin and vancomycin. Fosfomycin is a member of a class of compounds called phosphonic acids because they contain a carbon-phosphorous bond. Fosfomycin functions by inactivating an essential enzyme involved in the formation of the bacterial cell wall. ...

BGSU biologist trying to crack microscopic code

...ane is stabilized by a grid of sugar polymers, and penicillin wrecks the grid, making the cells susceptible to a body's natural defenses. Disrupting energy flow--knocking out the TonB and Tol systems--would provide another powerful weapon against disease-causing bacteria, he says, but researchers must first u...

Study indicates dramatic rise in antibiotic-resistant community-acquired staph infections

...(MSSA), which can be treated by antibiotics in the penicillin or related groups (i.e, beta-lactam antibiotics). Previously, MRSA infections were usually restricted to hospital or healthcare-associated infections. This is clearly no longer the case. Henry M. Blumberg, MD, is the senior author of the study, ...

Evolution follows few of the possible paths to antibiotic resistance

...form can serve to inactivate antibiotics including penicillin and cefotaxime.
