Streptococcus pyogenes
[group A – Streptococci]and
Streptococcus agalactiae
[ group B – Streptococci]
The treatment of Streptococcus
1- Clindamycin
2- Erythromycin
3- Penicillin or Ampicillin
4- Cefepime or Cefotaxime or Ceftriaxone
5- Vancomycin
6- Chloramphenicol
7- Levofloxacin or Ofloxacin
8- Quinpristin – Dalfoprisin
Susceptibility testing of penicillin and other beta – lactams on isolates of Streptococcus pyogenes or Streptococcus agalactiae is not necessary for clinical purposes and need not to done routinely, because resistant strains have not been recognized.
Streptococcus species are intrinsically resistant to primary aminoglyloside; primary quinolones, colistin, Aztreonam , fuscidic acid and pefloxacin.
The result of Trimethoprime - Sulphamethoxazole is reported resistance because is not clinically effective for treatment.
The recommendation for Intrapartum prophylaxis for group – B – Streptococcus are Penicillin or Ampicillin, while Cefazolin is recommended for penicillin allergic women at low risk for anaphylaxis; while those at high risk for anaphylaxis may receive Clindamycin or Erythromycin.
When group – B- Streptococcus is isolated from a pregnant woman with severe penicillin allergy [high risk for anaphylaxis] Clindamycin and Erythromycin should be tested and reported.
