Urinary Excretion of Pneumococcal Cell Wall Polysaccharide in Children

Pediatr Infect Dis J. 2002 Aug;21(8):791-3. doi: 10.1097/00006454-200208000-00020.

Abstract

The urinary excretion of the cell wall polysaccharide of Streptococcus pneumoniae was studied in 92 children with the NOW test. Cell wall polysaccharide was detected in 65% of pneumococcal carriers and in 10% of noncarriers. Excretion rates were similar in healthy children and in children with acute otitis media. The high rate of antigen excretion among nonill carriers suggests that colonization is a major source of urinary antigen in children.
