Age- and serogroup-related differences in observed durations of nasopharyngeal carriage of penicillin-resistant pneumococci.
Using data from an ongoing Swedish intervention project, the observed durations of nasopharyngeal carriage of penicillin-nonsusceptible Streptococcus pneumoniae (PNSP) (MIC of penicillin G of >or=0.5 microg/ml) stratified by both pneumococcal serogroup and age of the carrier were compared. The means and 95% confidence intervals (CIs) were estimated by fitting a gamma distribution to the observe...
متن کاملPneumococci in biofilms are non-invasive: implications on nasopharyngeal colonization
Streptococcus pneumoniae (the pneumococcus) is an opportunistic pathogen that colonizes the human nasopharynx asymptomatically. Invasive pneumococcal disease develops following bacterial aspiration into the lungs. Pneumococci within the nasopharynx exist as biofilms, a growth phenotype characterized by surface attachment, encasement within an extracellular matrix, and antimicrobial resistance. ...
متن کاملPneumococci in the Urine
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 ...
متن کاملQuinolone resistance mechanisms in pneumococci.
Quinolones are widely used in the treatment of respiratory infections, in large part because of their activity against Streptococcus pneumoniae and other commonly encountered respiratory tract pathogens. Pneumococcal isolates that are resistant to these "respiratory quinolones" have now begun to emerge. Resistance is attributable to mutations affecting the intracellular targets of these drugs, ...
متن کاملCarriage of penicillin resistant pneumococci.
A survey of 303 urban and 156 rural children showed nasopharyngeal carriage of relatively resistant Streptococcus pneumoniae organisms in 14.2% and 19.2% of children, respectively. These organisms have minimum inhibitory concentrations for penicillin in the range of 0.12-1 microgram/ml. An analysis of 40 relatively resistant S. pneumoniae strains showed resistance to co-trimoxazole in 47.5%, tr...
