A potent antibiotic for a drug-resistant superbug

This article from the LA Times caught my attention.

. . . carbapenem-resistant Acinetobacter baumannii, or CRAB, is a nightmare for hospitals worldwide, as it kills roughly half of all patients who acquire it.

Identified as a top-priority pathogen by both the World Health Organization and the U.S. Centers for Disease Control and Prevention, CRAB is the most common form of a group of bacteria that are resistant to nearly all available antibiotics. Victims are typically hospitalized patients who are already sick with blood infections or pneumonia. In the U.S. alone, the bug sickens thousands and kills hundreds every year.

Now

researchers have identified a new antibiotic that appears to effectively kill A. baumannii.

The compound, zosurabalpin, attacks bacteria from a novel angle, disrupting the route that a key toxin takes on its journey from inside the bacterial cell to the outer membrane that shields the bug from the immune system’s defensive onslaughts.

The problem, of course, is that once this is in widespread use, the only bacteria left will be resistant.

It is a tough arms race to win.
