The increasing incidence and prevalence of multi-drug resistance (MDR) among contemporary Gram-negative bacteria represents a significant threat to human health. Since their discovery, β-lactam antibiotics have been a major component of the armamentarium against these serious pathogens. Unfortunately, a wide range of β-lactamase enzymes have emerged that are capable of inactivating these powerf...

CONTEXT The high prevalence of resistance to trimethoprim-sulfamethoxazole and other antimicrobials among Escherichia coli causing acute cystitis in women has led to increased use of alternative antibiotics. One such antibiotic, amoxicillin-clavulanate, has not been well studied. OBJECTIVE To compare the efficacy of a 3-day regimen of amoxicillin-clavulanate to that of a 3-day regimen of cipr...

OBJECTIVES To test the antimicrobial sensitivity of two periodontal pathogens to a panel of five orally administrable antibiotics in periodontal disease. STUDY DESIGN A total of 69 isolates of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis were processed using culture and biochemical tests. Selected colonies of A. actinomycetemcomitans and P. gingivalis were used to evalua...

A total of 97 anaerobic bacteria were tested for susceptibility to ampicillin, ampicillin-sulbactam, and amoxicillin-clavulanic acid by broth microdilution and disk elution methods, the results of which were compared with those of the reference agar dilution method. With the broth microdilution method, approximately 95% of MICs were within 1 dilution of those of the reference agar method, with ...

background: escherichia coli (ecoli) has been considered as the most common agent of urinary tract infection in all regions. recently, increased drug resistance has been lead to some problems in treatment related diseases. so, evaluation of resistance patterns of bacteria in each region could be a valuable guide for empirical treatment. methods: all referred urine sample to kermanshah central l...

Hydrogels have become advantageous materials used in biomedical applications as catheter, soft contact lenses or drug carrying vehicle due to their features like biocompatibility, insoluble property aqueous solutions, resistance environmental conditions pH, temperature. Periodontitis is an inflammatory disease which leads the loss of tissue attachment, gingival recession, tooth periodontal pock...

Objective: Urinary tract infections (UTIs) are one of the most common in children. The aim this study was to assess and compare etiology antibiotic susceptibility results urine cultures obtained between 2013-2015 2019-2021 evaluate local epidemiologic differences over years.
 Materials Methods: A total 1,000 samples with positive (500 each for periods) antibiogram were included study.&#x0D...

All 47 sequential blood culture isolates of viridans group streptococci obtained from febrile neutropenic patients receiving quinolone prophylaxis were susceptible to vancomycin, teicoplanin, and imipenem. Resistance to benzylpenicillin (MIC for 50% of isolates [MIC50], 0.125 microgram/ml) and ceftazidime (MIC50, 4 micrograms/ml) was common. Most isolates were susceptible to amoxicillin, co-amo...

The aim of the present investigation was to evaluate the subgingival aerobic and anaerobic flora of 13 dogs with periodontal disease and the susceptibility of these bacteria to antibiotics currently approved in Italy for treatment of canine infections. Of the anaerobic bacteria, Bacteroides fragilis was most frequently isolated, followed by Peptostreptococcus + Porphyromonas gingivalis and Prev...

BACKGROUND Resistance of Helicobacter pylori to the more frequently used antibiotics (metronidazole and clarithromycin) reduces eradication rates even with triple treatment. Determining the antibiogram profile of H pylori can take up to 14 days and delays appropriate treatment. AIMS To determine the role of screening agar plates for more rapid in vitro susceptibility of H pylori to metronidaz...
