Antimicrob Agents Chemother 1994. Resistance of Streptococcus pneumoniae to beta-lactam antibiotics.
Streptococcus pneumoniae is a gram positive anaerobic bacterial species which belongs to the Streptococcus genus of gram positive bacteria.
First line treatment for strep pneumoniae. Amoxicillin is first-line therapy with a likely beneficial effect in 80 to 90 of cases. Amoxicillinclavulanic acid with a slightly higher likelihood of success because of efficacy against beta-lactamase producing Haemophilus influenzae is the backup in cases of failure. Antibiotic treatment for serious pneumococcal infections typically includes broad-spectrum antibiotics until results of antibiotic sensitivity testing are available.
Antibiotic sensitivity testing shows which antibiotics will be most successful at treating a bacterial infection. Streptococcus pneumoniae are the most significant pathogens that are responsible for bacterial pneumonia. Read all about streptococcus pneumoniae treatment in the following write up.
Streptococcus pneumoniae is a gram positive anaerobic bacterial species which belongs to the Streptococcus genus of gram positive bacteria. The CDC and others recommend outpatient oral empirical antibiotics with a macrolide doxycycline or an oral betalactam amoxicillin cefuroxime Ceftin or. Amoxicillin clarithromycin or doxycycline.
Alternative if at high risk of treatment failure repeated courses of antibacterials previous culture with resistant or atypical bacteria or high risk of complications. Oral second line if no improvement after at least 2. Resistance of Streptococcus pneumoniae to beta-lactam antibiotics.
Resistance of Streptococcus pneumoniae to the fluoroquinolones doxycycline and trimethoprim-sulfamethoxazole. Resistance of Streptococcus pneumoniae to the macrolides azalides lincosamides and ketolides. 31 rijen Penicillin 10 days of oral therapy or one injection of intramuscular benzathine.

Ricard JD Wolff M Lacherade JC et al. Levels of vancomycin in cerebrospinal fluid of adult patients receiving adjunctive corticosteroids to treat pneumococcal meningitis. Streptococcus anginosus Penicillin G is 1st line ceftriaxone is 2nd line.
Streptococcus pyogenes Group A strep or Streptococcus agalactiae Group B strep Penicillin G is 1st line cefazolin is 2nd line. Streptococcus pneumoniae not meningitis Ceftriaxone is 1st line Vancomycin is 2nd line in severe allergy. Infections caused by resistant pneumococci can still be treated using first-line antibacterials beta-lactams provided the dosage is optimised to cover less susceptible strains.
Macrolides can no longer be used as monotherapy but are combined with beta-lactams to cover intracellular bacteria. Thus based on current levels of resistance to penicillin and cephalosporin most patients with mildmoderate pneumococcal pneumonia may respond to oral amoxicillin and most with severe pneumonia may be successfully treated with intravenous ceftriaxone cefotaxime or. In the United Kingdom amoxicillin is used as first-line therapy in the vast majority of patients acquiring pneumonia in the community sometimes with added clarithromycin.
