Abstract
Bacterial sensitivity to cephalotine (Kf), cefuroxime (Zinacef) (Z) and ceftazidime (Fortum) (Case) was determined for some strains of coagulase-positive staphylococci, enterococci, E.coli, Klebsiella, Proteus and Pseudomonas aeruginosa isolated from hospital medium. The antimicrobial susceptib ility testing was performed by the Ki rby-Bauer method. This study has demonstrated that: 1. The staphylococci are resistent to the cephalosporins of the third generation (41,5%) and only 6,1% to Zinacef; 2. The enterococciare resistant >85% to all
cephalosporins; 3. The Gram-negative bacilli are resistant to the first generation of cephalosporins (94%-100% ) and they are susceptible to ceftazime (>6 9%); 4. The most frequent clinical materials are: pus (72%). sputum. throat swab (17% ); 5. The clinics with the gratest circulation of pathogenic strains are: surgery (50% of the isolated strains), new-born (30%), oprtopaedy (13%); 6. The most frequent of the isolated species are: staphylococci (35% of the strains), Klebsiella (26% ). E.coli. (9%). 7.39,6% of the strains are resistant to one antibiotic. 29 .3% are res i st ant to 2 ant ibiotics, and 12,8% are resistant to all 3 antibiotics. 43 strains (18.3%) have no resistance to the caphalosporins used in this study.
