چکیده

Streptococcus pneumoniae is the major cause of bacterial meningitis. We report a case of meningitis due to a mixed infection with two distinct strains of S. pneumoniae: one penicillin-resistant strain of serotype 9V and one penicillin-susceptible strain of serotype 7. The two strains exhibited different pulsed-field gel electrophoresis profiles.

Antibiotic therapy and acute outcome of meningitis due to Streptococcus pneumoniae considered intermediately susceptible to broad-spectrum cephalosporins.

Children with meningitis due to Streptococcus pneumoniae isolates that are relatively or fully resistant to penicillin and have decreased susceptibility to broad-spectrum cephalosporins (MIC, > or = 2.0 micrograms/ml) who have failed treatment with broad-spectrum cephalosporins have been reported. The National Committee for Clinical Laboratory Standards has newly revised guidelines indicating t...

Drug-resistance in Streptococcus pneumoniae isolates among Spanish middle aged and older adults with community-acquired pneumonia

BACKGROUND Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicillin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults. METHODS Antimicrobial susceptibility...

Experimental lobar pneumonia due to penicillin-susceptible and penicillin-resistant Streptococcus pneumoniae in immunocompetent and neutropenic rats: efficacy of penicillin and teicoplanin treatment.

Lobar pneumonia models were established in rats by intratracheal inoculation of either penicillin-susceptible (immunocompetent model) or penicillin-resistant (immunocompetent and neutropenic models) Streptococcus pneumoniae. Untreated animals maintained a relatively high bacterial load in the lungs but only occasionally developed bacteraemia or pleurisy. The infection was rarely fatal in immuno...

Phenotypes and genes of resistance of pneumococci to penicillin isolated from children.

UNLABELLED (Full text is available at http://www.manu.edu.mk/prilozi). In recent decades, the increase of Streptococcus pneumoniae strains resistant to beta-lactams, to other classes of antimicrobial drugs and especially to penicillin (penicillin-resistant pneumococcus - PRP) has further complicated the treatment of pneumococcal infection. Penicillin resistance in pneumococci is due to the deve...

In vivo efficacy of a new fluoroquinolone, sparfloxacin, against penicillin-susceptible and -resistant and multiresistant strains of Streptococcus pneumoniae in a mouse model of pneumonia.

The increasing emergence of penicillin-resistant and multiresistant strains of Streptococcus pneumoniae may pose a problem in coming years. We therefore compared sparfloxacin, a new fluoroquinolone with improved potency against streptococci, with amoxicillin, the "gold standard" in this setting, and another fluoroquinolone, ciprofloxacin, in a mouse pneumonia model. Their efficacies against pen...
