Staphylococcus species
The antibiotics used for treatment of staphylococcus organisms are:
1- Azithromycin or Clarithromycin or Erythromycin
2-Clindamycin
3-Oxacillin
4-Penicillin
5-Trimethoprim – Sulphamethoxazole
6- Linezolid
7-Telithromycin
8-Doxcycline or Tetracycline
9-Vancomycin
10-Chloramphenical
11- Ciprofloxacin or Levofloxacin or Ofloxacin
12-Moxifloxacin
13-Gentamicin
14- Quinpristin – Dalfoprisin
For urinary tract infection:
1-Lemefloxacin or Norfloxacin
2- Nitrofurantion
3- Sulfisoxazale
4-Trimethoprim
A-staphylococcus aureus
The percentage of resistant staphylococcus aureus isolated in medical city central teaching laboratory to antibiotics (from July 1st to December 28th 2009)
86% Penicillin
38% Doxcycline
86% Gentamicin
50% Oxacillin
41% Erythromycin
30% Ciprofloxacin
B- Non staphylococcus aureus
The percentage of resistant staphylococcus other than staphylococcus aureus isolated in medical city central teaching laboratory to antibiotics (from July 1st to December 28th 2009)
72% Oxacillin
96% Penicillin
1.6% Amikacin
67% Gentamicin
30% Ciprofloxacin
80% Erythromycin
Staphylococcus species may develop resistance during prolonged antimicrobial therapy with Fluoroquinolone. Testing of isolates recovered three or four days after initiation of therapy may be warranted to detect increasing resistance
Staphylococcus organism are intrinsically resistant to primary quinolones , colistin, Aztreonam.
The penicillin – susceptible staphylococcus are also susceptible to other penicillin; β-lactam – β - lactamase inhibitor combination, cephems and carbapenems.
Oxacillin – resistant staphylococcus (MRS) strains, also resistant to all penems, cephems; and other β-lactams such as amoxicillin – clavulanic acid; piperacillin tazobactam and carbapenems; may appear to be susceptible in vitro but not effective clinically.
