Lysogeny of Streptococcus pneumoniae with MM1 phage: improved adherence and other phenotypic changes.
Pneumococcal prophages are extremely frequent, but no role in pathogenesis has so far been attributed to them. We isolated a variant of phage MM1, named MM1-1998, from a serotype 24 strain of Streptococcus pneumoniae. We created three isogenic strain pairs (serotypes 3, 4, and 24) that differed only by the lysogenic presence of the MM1-1998 phage and did a phenotypic comparison. Lysogeny led to...
متن کاملCloning of Minor Autolysin of Streptococcus Pneumoniae
Abstract Background and Objective: Increased antibiotic resistant strains and inadequacy of current vaccines against pneumococcal infections necessitate the study of novel protein antigens. It seems that minor autolysin of Streptococcus pneumoniae may have antigenicity. Thus, we aimed at cloning its gene for the first time. Material and Methods: After DNA extraction of Streptococcus pneumoniae ...
متن کاملMacrolide Resistance in Streptococcus pneumoniae
Streptococcus pneumoniae is a common commensal and an opportunistic pathogen. Suspected pneumococcal upper respiratory infections and pneumonia are often treated with macrolide antibiotics. Macrolides are bacteriostatic antibiotics and inhibit protein synthesis by binding to the 50S ribosomal subunit. The widespread use of macrolides is associated with increased macrolide resistance in S. pneum...
متن کاملStreptococcus pneumoniae infections in neonates
To the Editor: The insurance industry has used the thirdgeneration ELISA protocol as a screening test for human immunodeficiency virus (HIV) infection over the last number of years. In order to utilise new technology and keep up with developments in the clinical field, the fourth-generation Combi protocol has been developed in consultation with experts and discussion with the National Pathology...
متن کاملBiofilm formation in Streptococcus pneumoniae
Biofilm-grown bacteria are refractory to antimicrobial agents and show an increased capacity to evade the host immune system. In recent years, studies have begun on biofilm formation by Streptococcus pneumoniae, an important human pathogen, using a variety of in vitro model systems. The bacterial cells in these biofilms are held together by an extracellular matrix composed of DNA, proteins and,...
