Bacterial Antigen Testing

Slide 8

September 2010

In bacterial antigen testing, reagent antibodies react with antigens contained in bacteria that are common causes of bacterial meningitis (such as, Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis, E coli, group B streptococcus). In infected individuals, the antigens may be present in the CSF (for patients with meningitis), in the blood (in the case of sepsis), or in the urine (which can occur in patients with either meningitis or sepsis).
