The dependence of the antibacterial activity of the two oral cephalosporins cefixime and cefaclor on pharmacokinetic properties was investigated in an in vitro model using strains of enterobacteria and a streptococcal strain. In the cultures the course of serum concentrations of the respective antibiotic was simulated. The more rapidly attained (1 h) high peak levels (17.5 micrograms/ml) of cefaclor (500 mg dose) in no case showed an advantage over the more slowly reached (3 h) low peak levels (2.5 micrograms/ml) of cefixime (200 mg dose). Cefixime was comparable to cefaclor with respect to its initial killing velocity, whereas it was generally superior with respect to maximum values for reduction of bacterial counts. Due to its long elimination half-life (2.5 h) cefixime prevented regrowth for at least twice as long as cefaclor, which has a short half-life (0.7 h). As a result of its antibacterial activity and pharmacokinetic properties cefixime can be administered less frequently than cefaclor.

198 urine samples were culture-positive and 175 isolates were included in the final analysis. E coli was detected in 50% of cultures, followed by Staphylococcus epidermidis (9%), Enterococcus faecalis (9%) and Klebsiella pneumoniae (5%). The detection rate of ESBL-producing E coli was 53%. Resistance to levofloxacin was the most common among all the isolates. Nitrofurantoin and fosfomycin tromethamine had the greatest activity against E coli; overall, 92% and 91% of isolates were susceptible to these antimicrobials. E faecalis had the highest susceptibility rates to fosfomycin tromethamine (100%).

The spectrum of antibiotic susceptibility of Borrelia burgdorferi has been only partially defined. In the present study the effectiveness of 12 antimicrobials, belonging to six different antibiotic classes have been tested against Borrelia burgdorferi s.s. (N=3), Borrelia garinii (N=3), Borrelia afzelii (N=3), Borrelia valaisiana (N=1), and Borrelia bissettii (N=1) isolates. These isolates were analysed by a new standardised colorimetric minimal inhibitory concentration (MIC) method based upon colour changes that result from actively metabolizing spirochaetes after 72 h of incubation. Piperacillin (MIC90: 0.08 mg/l), ceftriaxone (MIC90: 0. 04 mg/l), cefotaxime (MIC90: 0.15 mg/l), azithromycin (MIC90: 0.015 mg/l), roxithromycin (MIC90: 0.05 mg/l) and quinupristin/dalfopristin (MIC90: 0.12 mg/l) gave the lowest MIC values. Minimal inhibibitory activity of amoxycillin (MIC90: 1.04 mg/l), cefixime (MIC90: 1.33 mg/l), cefoperazone (MIC90: 0.83 mg/l) tetracycline (MIC90: 0.29 mg/l) and minocycline (MIC90: 0.30 mg/l) was slightly lower, whereas borrelia were resistant to amikacin (MIC90: >128 mg/l). Mean minimal borreliacidal concentrations (MBCs) were representatively determined for piperacillin (MBC: 1.8 mg/l), ceftriaxone (MBC: 2.0 mg/l), azithromycin (MBC: 0.82 mg/ml), roxithromycin (MBC: 1.8 mg/l), quinupristin/dalfopristin (MBC: 5.0 mg/l), minocycline (MBC: 5.8 mg/l), and amikacin (MBC: >128 mg/l) by using conventional subculture for three weeks in combination with dark-field microscopy. B. garinii proved to be the most susceptible of the genospecies tested. Our study showed excellent in vitro antimicrobial activity of all classes of antibiotics tested, except the aminoglycosides and hence their suitability for therapy of Lyme disease.

In this cross-sectional study, 100 strains of E. coli were isolated from patients with Urinary tract infection. After diagnosis of bacteria, genomes were extracted. Then, presence of integron class 1 was evaluated by using PCR. Antibiotic susceptibility testing method, the micro dilution broth was performed according to the standard CLSI2010. Data were analyzed using SPSS16 software.
Initial antibiotic therapy in upper and lower respiratory tract infections is usually empirical. However, the decreasing susceptibility of respiratory pathogens to antibacterials have raised concerns about the decreasing efficacy of currently available antibiotics.

Neisseria gonorrhoeae (NG) infection is a serious public health problem. The third-generation extended-spectrum cephalosporins (ESCs) have been used as the first-line treatment for NG infection for almost three decades. However, in recent years, treatment failures with the oral third-generation ESCs have been reported worldwide. This study aimed to estimate worldwide susceptibility rates of NG to cefixime and cefpodoxime by analyzing data from all relevant published studies.

The activities of six agents commonly used in treating infections of the skin and soft tissues and the action of selected cephalosporins against 15 isolates of Pasteurella multocida were assessed by a macro-broth dilution method. Broad-spectrum cephalosporins, including ceftriaxone and cefixime, had excellent in vitro activities (MIC less than or equal to 0.098) against the isolates tested.
Gonorrhea is the most common reportable disease in the United States. In recent years, the epidemiology of this infection has changed as a result of increasing drug abuse, exchange of money and drugs for sex, and sexual promiscuity among teenagers, particularly blacks. Significant numbers of asymptomatic male carriers have been identified, which presents an additional challenge to disease control. Gonococcal infection has become increasingly resistant to traditional antibiotic therapy and now requires the use of newer, more expensive agents. Single-dose oral treatment with cefixime (Suprax) or a quinolone appears to be effective, safe, and practical for patients with uncomplicated gonorrhea. Serious infection and new syndromes caused by gonococci continue to be reported. Because disseminated infections can be fatal, hospitalization and treatment with intravenous antibiotics such as ceftriaxone sodium (Rocephin) or cefotaxime sodium (Claforan) are required.

Minimal inhibitory concentrations (MICs) of the oral cephalosporin BAY v 3522, and of cephprozyl, cefaclor, cefixime, cefuroxime, cefetamet, cefpodoxime and cefotaxime were determined against Gram-positive and Gram-negative clinical isolates with the NCCLS agar dilution procedures. BAY was the most active drug against Gram-positive organisms. MICs ranged from 0.01 mg/l against group A streptococci to 16 mg/l against S. faecium. Although mean MICs of BAY against methicillin-resistant S. aureus and S. epidermidis were between 0.9-1.8 mg/l, respectively, such strains showed typical heteroresistance in population studies. In addition, the biochemical correlate of methicillin-resistance, the PBP-2', showed similar low affinity to BAY as methicillin. beta-lactamase-producing H. influenzae and B. catarrhalis were inhibited by 2-8 and 0.25-2 mg/l, respectively, whereas non-producers were inhibited by 0.25-2 and 0.12-1 mg/l of the drug. The activity of BAY against enterobacteriaceae was rather low. Ampicillin-susceptible E. coli strains were inhibited by 2-8 and resistant strains by 8-32 mg/l. The mean MIC against cephalothin-susceptible K. pneumoniae strains was 2.8, and that against resistant strains 27.4 mg/l. MICs against beta-lactamase-producing enterobacteriaceae determined in broth dilution were 4-8 times higher than those determined in agar dilution. Bactericidal activity was measured in killing-curve experiments at 4 times the MIC. BAY killed equally well as standard control drugs.
