Patent ID: 7642068

Claim:
An array for detecting Streptococcus pneumoniae following opsonophagocytosis, wherein the array comprises: a plurality of containers comprising wells present on at least seven multi-well plates, wherein the wells on each plate contain a different growth inhibitory substance associated with a target serotype-specific antibiotic-resistant Streptococcus pneumoniae for that plate and wherein the target Streptococcus pneumoniae associated with each plate are resistant to and grow in the growth inhibitory substance associated with that plate, but are not resistant to and do not grow in the presence of other growth inhibitory substances associated with the other plates and wherein the different growth inhibitory substances comprise 4 μg/ml chloramphenicol, 154 μg/ml spectinomycin, 400 μg/ml streptomycin, 1.5 μg/ml rifampicin, 19 μg/ml trimethoprim, 1.2 μg/ml optochin, and 0.5 μg/ml penicillin, a growth medium that supports growth of the target serotype-specific antibiotic-resistant Streptococcus pneumoniae associated with that plate, and a metabolic colorimetric indicator comprising a fluorescent signal indicating bacterial viability.
