Fifty-six blood donor sera were examined by indirect immunofluorescence for IgG antibodies to a selection of anaerobic bacterial strains, often isolated from wound cultures. Another 25 sera were examined by IgG antibodies to six NCTC Bacteroides strains. A wide range of IgG antibody titres were found against Fusobacterium, Clostridium, and anaerobic streptococcal species. Very low titres were f...
A strain of Bacteroides fragilis with high-level chromosomal resistance to rifampicin was isolated by blood culture from a patient with bacteraemia after gastrointestinal surgery. He had been receiving antituberculous therapy with rifampicin for nine months. This resistance led to some difficulty in the recognition and identification of the isolate by methods that depended upon antibiotic sensi...
Antibodies targeting CTLA-4 have been successfully used as cancer immunotherapy. We find that the antitumor effects of CTLA-4 blockade depend on distinct Bacteroides species. In mice and patients, T cell responses specific for B. thetaiotaomicron or B. fragilis were associated with the efficacy of CTLA-4 blockade. Tumors in antibiotic-treated or germ-free mice did not respond to CTLA blockade. ...
