[Urinary tract infection in gynecology-obstetrics: resistance to beta-lactam antibiotics and previous antibiotic therapy].

From June 1988 to October 1989, 190 women from the department of Obstetrics-Gynecology with bacteriuria due to Gram-negative rods were studied. One hundred and three were investigated as ambulatory patients. Fifty three had received treatment with a bêta-lactam antibiotic during the past three months and 11 between three and six-months before sampling.
