INTRODUCTION. From the beginning of the antibiotic era to the mid-1970s, Streptococcus pneumoniae (pneumococcus) remained uniformly susceptible to all classes of antibiotics that had been active against this organism, with the possible exception of tetracycline. Thus, the medical profession had a rude awakening in 1977 and 1978 when outbreaks of infection due to antibiotic-resistant ...Streptococcus pneumoniae remains the most common etiologic agent of bacterial meningitis in children above one month and adults of all ages.

The organism produces several virulence factors that are involved in the disease process. The molecular basis of the action of some of these virulence factors is being elucidated.Background: Patients with sickle cell disease (SCD) are at risk of fatal sepsis with encapsulated bacteria, such as Streptococcus pneumoniae, because of the inherent autosplenectomy that occurs in SCD. This risk is thwarted with oral penicillin prophylaxis during the first 5 years of life, and with stringent vaccination against S. pneumoniae alongside routine childhood immunization.Streptococcus pneumoniae is the bacterium that has historically been the most common pathogen to cause CAP worldwide. In the era before antibiotics, S. …Precise methods for the detection of Streptococcus pneumoniae are needed for predicting the consequences of pneumococcal conjugate vaccines on nasopharyngeal carriage.

Streptococcus pneumoniae (pneumococcus) is an important human pathogen that causes pneumonia, meningitis, sepsis, and otitis media. This bacterium normally resides in the nasopharynx as a commensal, but sometimes disseminates to sterile sites of humans and causes local or systemic inflammation.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.
