Serotype 1 Streptococcus pneumoniae is a leading cause of invasive pneumococcal disease (IPD) worldwide, with the highest burden in developing countries. We report the whole-genome sequencing analysis of 448 serotype 1 isolates from 27 countries worldwide (including 11 in Africa). The global serotype 1 population shows a strong phylogeographic structure at the continental level, and within Afri...
Soluble antigens of Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitidis, and group B streptococcus were looked for in cerebrospinal fluid, serum, and urine by using the staphylococcal coagglutination test, latex agglutination test, and counterimmunoelectrophoresis. The staphylococcal coaggultination and latex agglutination tests were more sensitive than counterimmuno...
We report a case of septicaemia and death due to occult sinusitis in an otherwise healthy adult. Septicaemia was diagnosed on clinical grounds and blood culture grew Streptococcus pneumoniae. Maxillary sinusitis was discovered incidentally on a CT scan four days after the onset of symptoms. A sinus wash-out revealed pus which on culture was positive for Streptococcus pneumoniae. The patient det...
Objective Little attention has been given to acute hematogenous osteomyelitis (AHO) caused by group A -hemolytic Streptococcus (GABHS), although up to 10% of cases are caused by this microorganism. The objective of this study was to define the clinical and laboratory characteristics of AHO caused by GABHS. Methods. Between January 1983 and June 1999, 29 patients were treated at Children’s Natio...
As early as 1902, Neufeld observed that the capsulated pneumococcus showed a peculiar change when it was treated with its specific antiserum, but for a number of years the important practical value of this reaction had not been realized and until our knowledge that there are several serological types of pneumococcus was fully established this reaction had not been utilized in the typing of the ...
most interesting were those having all the characteristic appearances of Fraenkel's pneumococcus. The preparation was stained by Gram's method, and it will be noticed that a clear capsule exists round the diplococci, which are in single pairs and in chains. The organism which is generally known as Fraenkel's pneumococcus was discovered by Sternberg and Pasteur in 1880. It was found by Fraenkel ...
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...
Streptococcus pneumoniae is a major cause of pneumonia, meningitis, septicemia, acute otitis media, and other serious infections, severely affecting infants, young children, and the elderly. In the past, S. pneumoniae was uniformly susceptible to penicillin, which remained the drug of choice for serious infections. However, since the mid-1960s, resistance to penicillin, which was first reported...
To the Editor: In recent years, antimicrobial drug resistance in Streptococcus pneumoniae has increased worldwide and is a major health concern. Resistance to β-lac-tams and macrolides, considered to be first-line therapeutic agents, is particularly high in France and many Asian countries (1–3). Resistance to new fluoroquinolones is reported with increasing frequency, which emphasizes the need ...
