Chromogenic cephalosporin test
Webmethods. Serotyping was done by a coagglutination test and by molecular PCR capsular genotyping. Beta-lactamase production was determined by the chromogenic cephalosporin test with nitrocephin as substrate. Most of the isolated H. influenzae strains were from children under 5 years of age (57.7%). Overall, 61 strains WebThe chromogenic cephalosporin test, also known as nitrocefin (cefinase test) (BD BBL-Becton Dickinson and Company, Sparks, USA) has been applied [17,18]. The cefinase discs contain nitrocephin (chromogenic cephalosporin), and each disc is used to evaluate the production of b-lactamase in a clinic isolated.
