Wadhwa G, Setiya K, Imran Hazra, Mohan T Madhan., In silico Identification of Streptococcus. pneumoniae by Microarray, Onl J Bioinform., 24 (3):145-155, 2023. Streptococcus pneumoniae is a gram-positive, anaerobic bacterium inducing pneumonia. We developed microarray expression data to identify co-expressed genes with virulent ones as drug targets. We predicted virulent, paralogous and co-expressed genes of corresponding protein drug targets by microarray data. Essential genes dissimilar to host genome were selected from 4508 expressed genes with time gap of ~8-10 minutes with 21 virulent ones, 18 similar to human and 19 to gut flora to yield 13 gene drug targets.

Keywords: clusters, k-mean clustering, drug targets.
