Postinfection intraconjunctival administration of MAb to PNAG reduces bacterial burdens and conjunctival pathology due to S. pneumoniae (strains D-39 and ATCC8) and S. aureus (strain LAC) after 48 hours of conjunctival infection in A/J mice. A total of 10 μg of control IgG MAb (□) or MAb to PNAG (▵) were injected into the conjunctiva 4, 24, and 32 hours postinfection. Mice (n = 8 per group) were euthanized at 48 hours postinfection and pathology scores (upper row) and CFU/conjunctiva (lower row) were determined. Symbols represent individual animals, black lines the median, and gray lines the 95% CI, and one-sided P values were determined by nonparametric t-tests.
