RT Journal Article SR Electronic T1 Antibiotic susceptibility and biochemical properties of Streptococcus faecalis strains reacting with both D and G antisera. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1289 OP 1292 DO 10.1136/jcp.37.11.1289 VO 37 IS 11 A1 B R Birch A1 M G Keaney A1 L A Ganguli YR 1984 UL http://jcp.bmj.com/content/37/11/1289.abstract AB Thirty one of 60 consecutive isolates of Streptococcus faecalis produced a reaction in both D and G streptococcal grouping sera. A close correlation was found between this grouping reaction and haemolysin production, resistance to erythromycin, tetracycline, and trimethoprim, and delayed fermentation of sorbitol.
