Quinupristin-Dalfopristin Nonsusceptibility in Pneumococci from Sickle Cell Disease Patients
TLDR
Nonsusceptibilty to quinupristin-dalfopristin (Q-D) was absent from 105 non-SCD- associated pneumococcal isolates but was present in 33/148 SCD-associated isolates, and one-third of the isolates harbored a known resistance mechanism.Abstract:
Sickle cell disease (SCD) is a risk factor for fatal pneumococcal infection. Nonsusceptibilty to quinupristin-dalfopristin (Q-D) was absent from 105 non-SCD-associated pneumococcal isolates but was present in 33/148 (22%) SCD-associated isolates. One-third of the isolates harbored a known resistance mechanism. Q-D is not optimal for use for the treatment of pneumococcal infection in SCD patients.read more

TL;DR: A motif identified within the signal peptide of proteins is potentially involved in targeting these proteins to the cell surface of low–guanine/cytosine Gram-positive species.

TL;DR: In the analysis of the genome, a large number of new uncharacterized genes predicted to encode proteins that either reside on the surface of the cell or are secreted are identified and there may be new targets for vaccine and antibiotic development.

TL;DR: RDs are unequally distributed between invasive and noninvasive isolates, RD8a and RD10 are correlated with the propensity of an isolate to cause IPD, and PsrP is required for full virulence in mice.
