A plasmid in Streptococcus pneumoniae [PDF]
Journal of Bacteriology, 1979 Plasmid deoxyribonucleic acid has been detected in three related laboratory strains of Streptococcus pneumoniae. Strains D39S, R36, and R36NC each contain a minimum of two copies per cell of a 2.0-megadalton plasmid (pDP1). A plasmid twice as large as this smaller one is also present in much lower quantity in these strains, but neither plasmid is ...

Pneumonia and Streptococcus pneumoniae vaccine [PDF]
Archives of Pharmacal Research, 2017 Pneumonia is an inflammatory disease of the lung, responsible for high morbidity and mortality worldwide. It is caused by bacteria, viruses, fungi, or other microorganisms. Streptococcus pneumoniae, a gram-positive bacterium with over 90 serotypes, is the most common causative agent.

Macrolide Resistance in Streptococcus pneumoniae [PDF]
Frontiers in Cellular and Infection Microbiology, 2016 Streptococcus pneumoniae is a common commensal and an opportunistic pathogen. Suspected pneumococcal upper respiratory infections and pneumonia are often treated with macrolide antibiotics.

Fluoroquinolone-resistant Streptococcus pneumoniae
Emerging Infectious Diseases, 2006 To the Editor: In pneumococci, resistance to fluoroquinolones is associated with chromosomal mutations in the quinolone-resistance–determining regions (QRDR) of type II topoisomerase enzymes, predominantly gyrA and parC. Several mutations have been described in these enzymes, but only a few have been shown by in vitro studies to confer resistance: S81F

Telithromycin-resistant Streptococcus pneumoniae
Emerging Infectious Diseases, 2005 To the Editor: In recent years, antimicrobial drug resistance in Streptococcus pneumoniae has increased worldwide and is a major health concern. Resistance to β-lactams and macrolides, considered to be first-line therapeutic agents, is particularly high in France and many Asian countries (1–3).

Co-infections and antimicrobial resistance profile of Mycobacterium tuberculosis and Streptococcus pneumoniae among patients with pulmonary infections attending tertiary health facilities in Makurdi, Nigeria [PDF]
Microbes and Infectious Diseases, 2023 Background: Pulmonary infections (Pls) cause mortality in elderly patients that have co-morbidities. These infections are life-threatening in the younger population, especially in infants and children.

Journal of Microbiology, Immunology and Infection, 2015 Research on Streptococcus pneumoniae has revealed key aspects in the study of infectious diseases and pathogen evolution, but pneumococci remain a major cause of morbidity and mortality. New insights into the pathogenic mechanisms of this species confirmed the key role of the capsular polysaccharide but have also identified the important functions ...

Comparison of Molecular Method and Culture in Detection of Community Acquired Pneumonia in Under Five Year Children in Assam, India [PDF]
Journal of Clinical and Diagnostic Research, 2021 Introduction: Pneumonia is the single largest infectious cause of death in children worldwide. Aetiology of pneumonia can be identified using multiple diagnostic tools including culture, serology and Polymerase Chain Reaction (PCR); common pathogens ...

Lysogeny in Streptococcus pneumoniae [PDF]
Microorganisms, 2020 Bacterial viruses, or bacteriophages, are major contributors to the evolution, pathogenesis and overall biology of their host bacteria. During their life cycle, temperate bacteriophages form stable associations with their host by integrating into the chromosome, a process called lysogeny.
