[Materno-fetal infections caused by unusual germs. Apropos of 9 cases].
A retrospective study carried out from January 1981 through August 1988 identified nine cases of materno-fetal infections (Staphylococcus aureus, 1 case; Klebsiella pneumoniae, 3 cases; enterococcus, 3 cases; Hemophilus influenzae, 1 case; and Pneumococcus, 1 case) in six girls and three boys; four premature infants developed respiratory distress requiring mechanical ventilation. In four cases, maternal history found risk factors for infection. All patients developed circulatory failure and one had purulent meningitis. Diagnosis was confirmed upon recovery of the microorganism from a central sample in six cases; in three cases, only the peripheral cultures were positive but diagnosis was supported by the positive maternal history and by clinical findings. Bacterial species were not associated with specific clinical or biological features, but infections due to Hemophilus influenzae, Klebsiella pneumoniae and pneumococcus were particularly severe (two deaths and two infants with neurologic sequelae). In some studies, unusual microorganisms account for 46% of septicemias and 36% of purulent meningitis. Group D streptococci are the most common bacteria in this category and may account for 10% to 15% of early neonatal septicemias. Organism-specific features are analyzed on the basis of data from the literature. Concerning therapy, this epidemiologic aspect of materno-fetal infections complicates the choice of the initial antimicrobial agents; because third-generation cephalosporins are not effective on listeria and group D streptococci, we advocate more widespread use of the ureidopenicillins instead of ampicillin.
