Htibacterial activity ceftizoxime and its comparison with that of chloramphenicol, penicillin G, cephalexin, cefzoline and cephalothin
This study compares the inhibitory effect of ceftizoxime with that of penicillin G, chloramphenicol, cephalothin, cephalexin and cefzoline on Klebsiella pneumoniae, Proteus mirabilis, pseudomonas ruginosa, staphylococcus aureus, staphylococcus epidermidis, staphylococcus saprophyticus and Escherichia coli. The in vitro inhibitory effect of ceftizoxime on P. mirabilis, P. Aeruginosa, S.prophytic...
متن کاملEffect of penicillin G every three weeks on oral microflora by penicillin resistant Viridans Streptococci.
BACKGROUND Benzathine penicillin G every 3 weeks is the standard protocol for secondary prophylaxis for recurrent rheumatic fever. OBJECTIVE Assess the effect of Benzathine penicillin G on Streptococcus sanguinis and Streptococcus oralis in patients with cardiac valvular disease due to rheumatic fever receiving secondary prophylaxis. METHODS Oral streptococci were evaluated before (baseline...
متن کاملIn vitro bactericidal synergy of gentamicin combined with penicillin G, vancomycin, or cefotaxime against group G streptococci.
The in vitro bactericidal interactions of penicillin G, cefotaxime, or vancomycin in combination with gentamicin were compared against 20 group G streptococci by the timed kill curve method. Synergy was noted at the following frequencies: penicillin plus gentamicin, 80%; cefotaxime plus gentamicin, 85%; vancomycin plus gentamicin, 90%. There was no bactericidal antagonism observed.
متن کاملPenicillin-resistant and penicillin-tolerant mutants of group A Streptococci.
Penicillin-resistant and penicillin-tolerant mutants have been isolated from group A streptococci mutagenized by ethyl methane sulfonate. The resistant mutants had an elevated minimal growth inhibitory concentration for benzylpenicillin (minimal inhibitory concentration, 0.2 microgram/ml, as compared with the minimal inhibitory concentration of 0.006 microgram/ml in the penicillin-susceptible p...
متن کاملSERUM PENICILLIN LEVEL A FTER INTRAMUSCULA R INJECTION OF 1,200,000 UNITS OF BENZATHINE PENICILLIN G IN CHILDREN WITH RHEUMATIC FEVER
The most accepted method of secondary prophylaxis in rheumatic fever (RF) has been an injection of 1,200,000 units of benzathine penicillin G (BPG) every 4 weeks, but recurrences have been reported in some patients despite such a prophylaxis program. The WHO recommended BPG injections every 3 weeks in high risk patients and situations due to some published data in favor of inadequacy of on...
