  1. S. pneumoniae is the most common identifiable cause of otitis and the one associated with the greatest morbidity. Penicillin-susceptible and intermediately resistant pneumococci are likely to respond better to this treatment than to any other. No other oral therapy is likely to be more effective for resistant pneumococci
  2. Streptococcus Pneumoniae Streptococcus pneumoniae is a rare bacteria that can cause pneumonia, meningitis or a blood stream infection. The disease is spread from person-to-person by direct contact with respiratory secretions, like saliva or mucus. Symptoms generally include an onset of fever and shaking or chills
  3. Pneumococcal infections are caused by Streptococcus pneumoniae, a gram-positive, catalase-negative organism commonly referred to as pneumococcus

Streptococcus pneumoniae is a significant human pathogenic bacterium. S.pneumoniae was recognized as a major cause of pneumonia in the late 19th century and is the subject of many humoral immunity studies. Despite the name, the organism causes many types of pneumococcal infection other than pneumonia,. Streptococcus pneumoniae is currently the leading cause of invasive bacterial disease in children and the elderly.

Pneumonia is a disease of the lung that is caused by a variety of. Streptococcus pneumoniae is a gram positive, anaerobic bacterial species which belongs to the Streptococcus genus of gram positive bacteria. As you may have guessed by the name of this bacterial species, this one's the chief culprit responsible for the maximum cases of bacterial pneumonia Streptococcus pneumoniae (the pneumococcus) is the classic example of a highly invasive, Gram-positive, extracellular bacterial pathogen. It is a major cause of morbidity and mortality globally causing more deaths than any other infectious disease

Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis, which are typically transmitted via respiratory droplets, are leading causes of invasive diseases, including bacteraemic pneumonia and meningitis, and of secondary infections subsequent to post-viral respiratory disease.The aim of this study was to investigate the incidence of invasive disease due to these pathogens. Streptococcus pneumoniae is among the most common pathogens associated with chronic otitis media with effusion, which has been hypothesized to be a biofilm disease. S. pneumoniae has been shown to form biofilms, however, little is known about the developmental process, the architecture, and the changes that occur upon biofilm development.

Streptococcus pneumoniae je grampozitivní, fakultativně anaerobní, α-hemolytický, viridující kok, který roste ve dvojicích a má lancetovitý tvar. Běžně kolonizuje sliznici horních cest dýchacích v neopouzdřené formě (kolonizováno je 70 % dětí). Je to podmíněný patogen - v opouzdřené formě (pouzdro obklopuje celou dvojici) může vyvolávat závažné infekce. The species Streptococcus pneumoniae was originally described by Chester 1901.This name appeared on the Approved Lists of Bacterial Names 1980.

Deibel and Seeley 1974 (Approved Lists 1980) Introduction. Streptococcus pneumoniae and Haemophilus influenzae are human restricted respiratory pathogens, often found colonising the nasopharynx, capable of causing deadly meningitis, pneumonia and sepsis. In order to survive in the host, both bacteria have evolved analogous survival mechanisms, such as production of polysaccharide capsules to evade host immune responses

Abstract. Survival in the human host requires bacteria to respond to unfavorable conditions. In the important Gram-positive pathogen Streptococcus pneumoniae, cell wall biosynthesis proteins MurM and MurN are tRNA-dependent amino acyl transferases which lead to the production of branched muropeptides.We demonstrate that wild-type cells experience optimal growth under mildly acidic stressed.
