Streptococcus pneumoniae inflicts a huge disease burden as the leading cause of
community-acquired pneumonia and meningitis. Soon after mainstream antibiotic usage …

We have identified an unusual group of viridans group streptococci that resemble
Streptococcus pneumoniae. DNA-DNA homology studies suggested that a subset of these …

Antimicrobial drug resistance is a global health problem that continues to expand as micro-
organisms adapt to the antibiotics we use to treat them and as new classes of antimicrobial …

The nucleotide sequences of the lytA gene from 29 pneumococcal isolates of various
serotypes and 22 additional streptococci of the mitis group (including two Streptococcus …

The limitation of polymerase chain reaction (PCR) in diagnosis of lower respiratory tract
infections (LRTIs) caused by Streptococcus pneumoniae, Haemophilus influenzae, and …

We determined the usefulness of 4 conventional polymerase chain reaction (PCR) assays,
lytA, psaA, and two primer sets from the ply gene, for accuracy in the discrimination of …

The viridans group streptococci (VGS) are an extremely diverse range of organisms within
the genus Streptococcus, which are characterized by a greening of the blood in blood agar …

Populations of Streptococcus pneumoniae (SP) are typically structured into groups of closely
related organisms or lineages, but it is not clear whether they are maintained by selection or …

Eight optochin-susceptible (Opts) alpha-hemolytic (viridans) streptococcus isolates were
characterized at the molecular level. These isolates showed phenotypic characteristics …

Aim: The objective of this study is to compare various Streptococcus pneumoniae
identification methods. Materials & methods: In total, 1371 putative S. pneumoniae isolates …
