Abstract

In hypoxic and inflamed tissues, oxygen (O-2)-dependent antimicrobial defenses are impaired due to a shortage of O-2. To gain insight into the mechanisms that control bacterial infection under hypoxic conditions, we infected macrophages with the obligate intracellular pathogen Coxiella burnetii, the causative agent of Q fever. Our experiments revealed that hypoxia impeded C. burnetii replication ...
