RT Journal Article SR Electronic T1 Micrococcaceae from the urinary tract in pregnancy JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 631 OP 632 DO 10.1136/jcp.20.4.631 VO 20 IS 4 A1 Roberts, A. P. YR 1967 UL http://jcp.bmj.com/content/20/4/631.abstract AB Gram-positive, catalase-positive cocci (Micrococcaceae) have been obtained from the bladder by suprapubic aspiration of urine in antenatal and postnatal patients. These bacteria have been compared with similar organisms isolated from midstream specimens of urine when the suprapubic specimen was sterile. Fourteen (70%) of 20 organisms isolated from the bladder were micrococci and six (30%) were staphylococci. In contrast 17 (85%) of 20 similar organisms contaminating midstream urine specimens were staphylococci and only three (15%) were micrococci.
