Pathogen

Haemophilus influenzae

A small gram-negative coccobacillus, more familiar from the respiratory tract but detected on some wound and urinary panels.

How CORE-ABR grades it

Ampicillin resistance in H. influenzae is most often due to TEM-type beta-lactamase or altered penicillin-binding proteins, neither of which is a target on most panels — so absence of a detected gene does not establish ampicillin susceptibility.

What the report shows for Haemophilus influenzae

  • 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.

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.
