The invention provides a method and a kit for measuring the levels of serum fetuin-A in children to reflect the severity of invasive pneumococcal diseases caused by, including necrotizing pneumonia and hemolytic uremic syndrome. The mean fetuin-A levels in the HUS patients are significantly lower (207&#xb1;80 mg/L, p&#x3c;0.001) when compared to patients with lobar pneumonia (610&#xb1;190 mg/L) and the healthy controls (630&#xb1;250 mg/L). A serum fetuin-A level is a useful biomarker to classify the severity of pneumococcal infection in children. The level of biomarker fetuin-A can be monitored and evaluated by enzyme linked immunosorbent assay and Western blot hybridization.

A method of providing protection against pneumococcal infection in a subject is disclosed. The method includes steps of administering to the subject a composition that includes combination of three recombinant pneumococcal neuraminidases: NanA, NanB, and NanC ofstrains CGSP14, wherein administration of the recombinant pneumococcal neuraminidases elicits an immune response to, and treats the subject. In one embodiment, the method further includes a step of adding adjuvants to enhance the immune response. The method also includes a step of using passive antibodies, wherein said passive antibodies are anti-neuraminidase antibodies generated from neuraminidases-immunized humanized animals: NanA, NanB, and NanC. Meanwhile, this invention also provides a method for the molecular diagnosis of pneumococcal infection.
