title: [Isolation of beta lactamase enzyme in strains of Staphylococcus aureus with the method of starch paper].
abstract: The authors worked with 2,273 strains of Staphylococcus aureus isolated from clinical samples processed at the Microbiology laboratory of Centro Habana Pediatric Teaching Hospital in the period ranging from June 1985 to December 1986. All strains underwent the bacterial sensitivity test against antibiotics by Bauer-Kirby technique. Fourty-eight strains were sensitive to penicillin - which accounts for 2.11% - by the beta-lactamase detection test by the starch paper method. In all cases, negative results were obtained, which is in agreement with the results of the sensitivity tests.
