DIAS, Cícero A.G. et al. Agar diffusion tests with cefuroxime disks for predicting ceftriaxone susceptibility among isolates of Streptococcus pneumoniae. Rev. Microbiol. [online]. 1998, vol.29, n.4, pp.314-316. ISSN 0001-3714.

The performance of agar diffusion tests using disks of cefuroxime (30µg) for predicting ceftriaxone susceptibility in 33 isolates of Streptococcus pneumoniae was studied. All 7 resistant isolates to ceftriaxone (MIC ³1.0 µg/ml) exhibited zones of inhibition <28mm. The procedure can be easily adapted to clinical laboratories.

Keywords : Screening test; resistance; pneumococcus.
