PavA of Streptococcus pneumoniae modulates adherence, invasion, and meningeal inflammation.
Pneumococcal adherence and virulence factor A (PavA) is displayed to the cell outer surface of Streptococcus pneumoniae and mediates pneumococcal binding to immobilized fibronectin. PavA, which lacks a typical gram-positive signal sequence and cell surface anchorage motif, is essential for pneumococcal virulence in a mouse infection model of septicemia. In this report the impact of PavA on pneu...
متن کاملAerobic exercise attenuates pulmonary inflammation induced by Streptococcus pneumoniae.
Aerobic exercise has been recognized as a stimulator of the immune system, but its effect on bacterial infection has not been extensively evaluated. We studied whether moderate aerobic exercise training prior to Streptococcus pneumoniae infection influences pulmonary inflammatory responses. BALB/c mice were divided into four groups: Sedentary Untreated (sedentary without infection); Sedentary I...
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 کاملAdhesion and invasion of Streptococcus pneumoniae to primary and secondary respiratory epithelial cells
The interaction between Streptococcus pneumoniae (S. pneumoniae) and the mucosal epithelial cells of its host is a prerequisite for pneumococcal disease development, yet the specificity of this interaction between different respiratory cells is not fully understood. In the present study, three areas were examined: i) The capability of the encapsulated S. pneumoniae serotype 3 strain (WU2) to ad...
متن کاملDrug-resistant Streptococcus pneumoniae.
Streptococcus pneumoniae remains a major cause of infection in both children and adults, annually resulting in significant morbidity and mortality. The past two decades have seen an alarming worldwide increase in the incidence of drug-resistant S. pneumoniae (DRSP). DRSP is now common throughout the United States, and physicians are questioning how best to approach this epidemic. With the intro...
