Researchers have identified a new bacterium in a severely ill patient. Other members of this microbial family, Acetobacteraceae, are used in the vinegar-making industry and aren't known to cause disease, says study coauthor David E. Greenberg, a physician at the National Institute of Allergy and Infectious Diseases in Bethesda, Md.
The patient, a 39-year-old man, had chronic granulomatous disease (CGD), a rare, inherited immune disorder that permits opportunistic pathogens to cause infections. This patient, who had a fever and infected lymph nodes in his lungs, had failed to respond to 3 months of antibiotic and other treatments. Analysis of lymph tissue removed from the patient revealed an Acetobacteraceae bacterium that differed from known microbes.
