OBJECTIVES The objective of this multicentre study was to define the accuracy and reproducibility of the NCCLS disc diffusion method for Haemophilus influenzae against ampicillin and co-amoxiclav in Finnish clinical microbiology laboratories. Special attention was paid to the ability of the laboratories to detect beta-lactamase-negative ampicillin-resistant (BLNAR) strains. METHODS Three BLNA...
Abstract Background and Objective: Resistance of Helicobacter Pylori (H. pylori) to antibiotics is the main cause of relapse into Helcobacterial infections. With the use of several antibiotics that have synergistic effect, we can inhibit this antibiotic resistance. Thus, we aimed at determining resistance patterns and assessing the synergy of combining multiple antibiotics on H. pylori. ...
Clinically, antimicrobial susceptibility testing results provide guidance in the choice of agents patient care. The accuracy from can be affected by multiple factors including media, discs or preparations, inoculum’s size, plate reading and incubation conditions. Misleading test leads to indiscriminate irrational use antibiotics have impacted grossly global challenge resistance. objectives this...
Abstract Background and Objectives: Concurrent with the development of new chemical drugs and antibiotics, their harmful effects are gradually emerged. Due to lack of harmful effects, herbal medicines have been used in the pharmaceutical industry. The aim of this study was the use of lavender essential oil as an herbal medicine for the replacement of antibiotics and chemicals. Material and ...
The role of antibiotics in the treatment of disc-space infection is controversial. This study assessed the tissue penetration of flucloxacillin and cephradine into the normal intervertebral disc after intravenous administration of a bolus dose of antibiotic. Twenty-five discs were removed from 12 adolescent patients having anterior spinal surgery to correct scoliosis; antibiotic had been admini...
Background: Septicemia is a life threatening status and needs rapid antibiotic treatment. Enterobacteriacea are one of the most important causes of septicemia. So this study is therefore aimed to evaluate antibiotic susceptibility of enterobacteriacea isolates in blood cultures in Shariati Hospital, Tehran, Iran. Methods: This retrospective study was performed on 138 patients with positive b...
A method for the determination of minimum inhibitory concentration (MICs) is described, in which commercially prepared antibiotic sensitivity testing discs are used as primary antibiotic standards from which the necessary dilutions are prepared in WHO Perspex haemagglutination plates. The materials required are readily available in most laboratories at a cost in time and reagents that compares ...
The purpose of this study was to determine the effect of the covalent incorporation of hyaluronic acid (HA) into conventional hydrogel and hydrogels containing silicone as models for contact lens materials on the uptake and release of the fluoroquinolone antibiotic ciprofloxacin and the anti-inflammatory steroid dexamethasone phosphate. A 3 mg/mL ciprofloxacin solution (0.3% w/v) and a 1 mg/mL ...
Background and Aim: To compare time, concentration and temperature dependent antimicrobial activity of sodium hypochlorite (NaOCl) against Enterococcus faecalis (E. faecalis). Materials and Methods: A total of 144 antibiotic discs were infected by E. faecalis; 6 antibiotic discs served as negative controls. Discs were further divided into 12 subgroups according to 2 contact times (1and 5min) an...
