Researchers have discovered new species of antibiotic-resistant bacteria in the blood of two patients in China, according to a recent study.
The study showed that the patients were carrying unidentified species of Enterobacter huaxiensis and Enterobacter chuandaensis that did not respond to penicillin or the cephalosporin group of antibiotics.
Enterobacteriaceae exist in the gut and are usually harmless. However, they can cause meningitis if they enter the blood or pneumonia if they get into the lungs, reported Daily Mail.
