Forty-seven Bordetella pertussis isolates recovered from January 1985 to June 1997 at Primary Children's Medical Center were tested for erythromycin resistance. Agar dilution MICs were determined on Regan-Lowe agar. Forty-six isolates were found to be erythromycin susceptible (all MICs were less than or equal to 0.12 microg/ml). One isolate was found to be erythromycin resistant (MIC, 32 microg...

Introduction & Objective: Urinary Tract Infection (UTI) is one of the most common infections during childhood and E-Coli is the more predominant pathogen recovered in UTI. Disk Diffusion agar test is a method of choice because it is cost effective, simple, and now routinely used for detection of antibiotic susceptibility. A rapid increase in antibiotic resistance in our region made the auth...

Using a freezing-thawing method for extracting colicine from solid media it has been shown that the choice of media for production and diffusion is important. Digest nutrient agar yielded the most colicine and peptone water agar the least. A factor in bacteriological peptone, but absent in a proteose peptone (Difco) and Neopeptone, was responsible for inhibiting production on peptone water agar...

Seven laboratories participated in a collaborative study to evaluate the Autobac 1 system. Results obtained with this assay system were compared to those obtained by the standardized Bauer-Kirby disk diffusion test, and each of these two methods was compared to the agar dilution technique. Comparison of the Autobac 1 and the disk diffusion results from the seven laboratories showed an overall a...

Ampicillin-sulbactam (A/S) and amoxicillin-clavulanic acid (AUG) are thought to be equally efficacious clinically against the Enterobacteriaceae family. In this study, the in vitro activities of the A/S and AUG were evaluated and compared against Escherichia coli and Klebsiella spp. Antimicrobial susceptibility tests were performed by standard agar dilution and disc diffusion techniques accordi...

Intra ocular implants of sodium alginate alone and in combination with hydroxypropylmethylcellulose with or without calcium chloride were formulated with indomethacin as a model drug. The drug release from the implants was evaluated using static method, continuous flow through apparatus (developed in house), USP dissolution and agar diffusion. Except in the static method, indomethacin particle ...

Background and Objective: Nowadays, incidence of antibiotic-resistance among pathogenic bacteria has increased due to indiscriminate use of antimicrobial drugs for treatment of diseases, especially urinary tract infections. Medicinal plants are also of great importance as antibacterial agents. Therefore, the aim of this study was to determine the antibacterial effect of ethanolic extract of n...

Based on the metachromatic property of Toluidine Blue O, three, convenient agar-diffusion methods have been developed that enable detection of the nuclease of Staphylococcus aureus at concentrations as low as 0.005 mug/ml in agar and broth cultures. The interactions of agar and deoxyribonucleic acid with Toluidine Blue O are discussed.

Twelve lots of commercially prepared Mueller-Hinton agar from four medium manufacturers were evaluated for performance with recommended quality control organisms, medium pH, agar depth and uniformity, and characteristics of the zones of inhibition. Only 2 of 12 lots were acceptable for disk diffusion susceptibility tests. Significant problems were observed with the preparation and pouring of th...

In vitro interaction of anidulafungin with voriconazole was tested by a microdilution broth checkerboard technique and an agar diffusion method against 30 Aspergillus clinical isolates belonging to five different species. By using a complete inhibition endpoint, indifferent interactions were observed for 97% of the isolates by the checkerboard technique (FIC index from 0.5 to 2) and for 100% of...
