Abstract
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.
