Sensitivity of coagulase-positive staphylococci. Study in various forms of pyoderma.

Introduction Numerous papers have been published about antibiotic-resistant staphylococci, particularly those resistant to penicillin. Most of these publications deal either with hospitalized patients or with healthy staphylococcal carriers. As knowledge about the sensitivity to antibiotics of coagulase-positive staphylococci in patients suffering from pyoderma is scanty 1-5 this work was undertaken. The aim was to study the difference in sensitivity to antibiotics of coagulase-positive staphylococci cultured from pyodermatic lesions in the outpatient department with regard to the following factors: Clinical type of pyoderma, e.g., impetigo, furuncle, infected trauma Contact with hospital before visiting the outpatient department Patient hospitalized during previous 12 months Other member of family hospitalized during previous 12 months No member of family so hospitalized In addition the sensitivity of the coagulase-positive staphylococci cultured in 2 parallel periods in 1958 and 1959 was compared. Since many patients did not know which medicines they had previously received, the connection between sensitivity of
