When researchers infected mice with Yersinia that lacked PLA, though, they found an infection ebbing in the lungs but spreading to the spleen. The mice still died, but it took them many days to do so longer. They figured the intense pneumonia and rapid death of pneumonic plague appears to depend on the activity of PLA. ‘Pharmaceutical businesses have huge libraries of protease inhibitors, so hopefully someone begins the search soon for an inhibitor of PLA that is specific and nontoxic enough to be used as an adjunct treatment,’ Goldman says. ‘That may give us enough time to use antibiotics to save patients afflicted with pneumonic plague.’ Goldman hopes to conduct follow-up research to learn more about how plague exploits PLA..
