How CORE-ABR grades it

Beta-lactams remain first line. Clindamycin and macrolide resistance through erm genes is common and is applied when detected.

What the report shows for Streptococcus agalactiae

  • Detected or not detected, with Ct, limit of detection and cycles above LOD — see PCR reporting.
  • A short pathogen summary, including colonizer likelihood where it applies.
  • A graded column on the antibiogram, and therapy options by scenario on the P.A.C.T. report.
  • When not detected, it is still listed among targets tested.

Resistance genes CORE-ABR applies

When detected, each of these genes is applied to Streptococcus agalactiae only for the agents its mechanism defeats.

Decision support only. The treating clinician decides. Molecular genotype does not replace phenotypic susceptibility testing, culture, or public-health reporting. Absence of a detected resistance gene does not establish susceptibility. Organism targets vary by panel; CORE-ABR is configured to the assay each laboratory runs.
