With the aid of sterile forceps, cephalothin
and nalidixic acid discs were placed on the surface of inoculated plate and incubated at 37[degrees]C for 3-6 days under microaerophilic conditions.
coli O157: H7 resistance in Cephalothin
coli, 13% of the isolated strains have shown resistance to the antibiotics amoxicillin with clavulanate, ampicillin, cephalothin
, cefepime, cefoxitin, ceftazidime, cefuroxime and meropenem.
The following antibiotics were used for bacteria isolated from urine cultures; amikacin (30ug), (20ug of amoxicillin + 10ug of clavulanate), cefotaxime (30ug), cephalothin
(30ug), gentamycin (10ug), nalidixic acid (30ug), nitrofurantion (300ug), norfloxacin (10ug), sulfamethoxazole (100ug) and vancomycin (30ug) (Bioanalyse, Turkey).
Extremely high resistance rates to ampicillin, cephalothin
, cefuroxime, amoxicillin-clavulante, and nitrofurantoin (91.1%-99.0%) were observed.
Antibiotics used in these studies were amikacin (Ak) amoxicillin (Am) ampicillin (A) carbenicillin (Ca) cefixime (Cfm) ceftizoxime (Cxm) ceftriaxone (Cz) cephalothin
(Cl) chloramphenicol (C) ciprofloxacin (Cip) co-trimoxazole (Co) enoxacin (E) erythromycin (Er) gentamicin (G) kanamycin (K) nalidixic acid (Na) penicillin (P) streptomycin (S) sulfamethoxazole-trimethoprim (SxT) and tetracycline (T).
The antibiotic tested included: ampicillin (10 [micro]g), augmentin (30 [micro]g), cloxacillin (30 [micro]g), cephalothin
(30 [micro]g), ciprofloxacin (5 [micro]g), chloramphenicol (30 [micro]g), trimethoprim (5 [micro]g), gentamicin (10 [micro]g), tetracycline (30 [micro]g), ofloxacin (5 [micro]g), and erythromycin (30 [micro]g) (Remel, USA).
It has been reported susceptible to amikacin, imipenem, cefoxitin, clarithromycin, ciprofloxacin, and cephalothin
. It has variable susceptibility to doxycycline.
Klebsiella spp., the second common germ producing UTI, showed the highest sensitivity to Ciprofloxacin (81.3%) and Amikacin (73.1%) and the highest resistance to Ampicillin (86.3%) and Cephalothin
The following antibiotic discs (Mast Diagnostics, UK) at the final concentrations that are indicated were used: ampicillin (AP) -10 [micro]g, cephalothin
(KF) 5 [micro]g, streptomycin (S) 10 [micro]g, erythromycin (E) 15 [micro]g, chloramphenicol (C) 30 [micro]g, neomycin (NE) 30 [micro]g, amoxycillin (A) 10 [micro]g, ciprofloxacin (CIP) 5 [micro]g, trimethoprim (TM) 25 [micro]g, kanamycin (K) 30 [micro]g, and oxytetracycline (OT) 30 pg.
The disks contained the following antibiotics: 10 [micro]g ampicillin, 30 [micro]g cephalothin
, 30 [micro]g cefotaxime, 30 ug ceftazidime, 30 [micro]g cefuroxime, 1 [micro]g dicloxacillin, 15 [micro]g erythromycin, 10 [micro]g gentamicin, 5 [micro]g pefloxacin, 10 IU penicillin, 30 [micro]g tetracycline, and 25 [micro]g trimethoprimsulfamethoxazole.
One gram of cephalothin
was injected 2 hours before surgery.
