Laboratory Detection of Vancomycin

If possible laboratories should incorporate the vancomycin agar screen plate for testing all S aureus Alternatively the screening may be limited to MRSA isolates since nearly all VISA and all VRSA reported to date (i e April 2006) were also MRSA Laboratories using disk diffusion to determine vancomycin susceptibility should consider adding a second method for VISA detection The

Simple Method for Plating Escherichia coli Bacteriophages

The use of low concentrations (optimally 2 5 to 3 5 μg/ml depending on top agar thickness) of ampicillin in the bottom agar of the plate allows for formation of highly visible plaques of bacteriophages which otherwise form extremely small plaques or no plaques on Escherichia coli lawns Using this method we were able to obtain plaques of newly isolated bacteriophages propagated after

Antibiotic Sensitivity Testing

The antibiotic contained in a reservoir is allowed to diffuse out into the medium and interact in a plate freshly seeded with the test organisms The disk is applied to the surface of an agar plate inoculated with the test organism The antibiotic diffuses out of the disk to form the gradient The test organism starts to divide and grow and progresses toward a critical mass of cells The
