Low-level resistance to rifampin in Streptococcus pneumoniae.
Rifampin is recommended for combination therapy of meningitis due to beta-lactam-resistant Streptococcus pneumoniae. High-level rifampin resistance (MIC, > or =4 mg/liter) has been mapped to point mutations in clusters I and III of rpoB of the pneumococcus. The molecular basis of low-level resistance (MICs, > or =0.5 and <4 mg/liter) was analyzed. Spontaneous mutants of clinical pneumococcal is...
متن کاملMacrolide Resistance in Streptococcus pneumoniae
Streptococcus pneumoniae is a common commensal and an opportunistic pathogen. Suspected pneumococcal upper respiratory infections and pneumonia are often treated with macrolide antibiotics. Macrolides are bacteriostatic antibiotics and inhibit protein synthesis by binding to the 50S ribosomal subunit. The widespread use of macrolides is associated with increased macrolide resistance in S. pneum...
متن کاملA global gene pool for high-level cephalosporin resistance in commensal Streptococcus species and Streptococcus pneumoniae.
Highly penicillin- and cephalosporin-resistant Streptococcus mitis and Streptococcus oralis were isolated in Spain, Hungary, and Berlin. With chromosomal DNA of these strains, resistant transformants of Streptococcus pneumoniae were obtained that expressed low-affinity variants of penicillin-binding proteins (PBPs) 2x, 1a, 2a, and 2b in different combinations, depending on the selective conditi...
متن کاملEmergence of Streptococcus pneumoniae with high-level resistance to cefotaxime in Hong Kong.
We report on two cases of pneumococcal infection caused by strains demonstrating high-level cefotaxime resistance (minimal inhibitory concentration, 4 µg/mL). One patient had acute community-acquired meningitis with bacteraemia and the other had bacteraemia probably as a result of nosocomial pneumonia. Both patients died despite treatment with third generation cephalosporins. This is the first ...
متن کاملDifference in Resistance to Streptococcus pneumoniae Infection in Mice
Streptococcus pneumoniae is a major pathogen that causes various diseases, including pneumonia and sepsis, as millions of people suffer from S. pneumoniae infection worldwide. To better understand the immune and inflammatory responses to S. pneumoniae, we produced murine models. To investigate the differences between intranasal and intratracheal infection, BALB/c mice were infected with S. pneu...
