Randomized Controlled Trial Clinical TrialLaboratory aspects of asymptomatic bacteriuria in pregnancy.
A total of 1,661 pregnant women aged between 13 and 45 years were screened for bacteriuria by urine culture. Of the 1,661 culture results, 615 (37%) yielded no growth; 728 (43.8%) yielded no significant growth (presence of <10(5) organisms/ml urine of one or more types of bacteria); 286 (17.2%) yielded mixed growth (presence of >10(5) organisms/ml urine of more than one type of bacteria) and only 32 (1.9%) showed significant growth (presence of >10(5) organisms/ml urine of a single bacterium). Urine microscopy was also conducted. ⋯ For Gram-positive organisms, of which Group B Streptococcus is important, ampicillin is still effective in vitro. Nitrofurantion and cotrimoxazole have excellent activity in vitro and should be considered for therapy. 17.2% of the urine culture yielded mixed growth: likely to indicate that contamination of urine specimens still happens despite the strict instructions given to patients about the collection of a midstream urine specimen. Proper collection, appropriate transport, and the early processing of urine specimens remain essential.

Randomized Controlled Trial Clinical TrialSymptomatic urinary tract infection in women in primary health care. Bacteriological, clinical and diagnostic aspects in relation to host response to infection.
To evaluate rapid diagnostic tests for bacteriuria in women with symptoms of urinary tract infection (UTI), and to analyse bacteriological and clinical findings in relation to host response to infection. ⋯ In women with a high probability of bacteriuria, i.e. those with symptoms of lower UTI, examination for pyuria and urinary nitrite offers high diagnostic efficacy. If either or both tests are positive urine cultures can be omitted.
