Streptococcus Pseudopneumoniae as an Emerging Respiratory Tract Pathogen at Assiut University Hospitals

Streptococcus pseudopneumoniae as suggested by DNA-DNA homology studies is recorded as a species of the Streptococcus mitis/oralis members of viridans group Streptococci; they have some similar features to the Streptococcus mitis/oralis members of viridans Streptococcus pneumoniae

Study Overview

Status

Unknown

Intervention / Treatment

Detailed Description

principle characteristics of Streptococcus. pseudopneumoniae are the lacking of pneumococcal capsule, bile insolubility, the indeterminate sensitivity Or resistance to optochin after incubation in Carbon dioxide (5%), while sensitivity to it after incubation in ambient air Streptococcus . pseudopneumoniae was firstly described in sputum samples of patients with lower respiratory tract infection, particularly those with Chronic Obstructive PulmonaryDiseases pseudopneumoniae is usually misidentified in our laboratories as we usually rely on optochin sensitivity testing with 5% Carbon dioxide detection of Streptococcus. pneumoniae and miss the incubation in ambient air which is the key point for identification of Streptococcus. pseudopneumoniae. Biochemical reactions are usually used to differentiate typical pneumoniae from Streptococc Streptococcus . pseudopneumoniae and other related Streptococci; several molecular techniques have also been used There are several polymerase chain reaction based assays that target specific pneumococcal virulence factors for the typical Streptococc Streptococcus . pneumoniae, such as autolysin A which is the major pneumococcal autolysin and the capsular polysaccharide biosynthesis gene A which is a conservedpneumococcal capsular polysaccharide gene , also aliB-like ORF2 (a gene that usually found in the capsular region of non-capsulated pneumococci; these genetic markers have been used to differentiate S. pneumoniae from other related species.
