Close mobile search navigation Article navigation. It furthers clsi m45-a2 University’s objective of excellence in research, scholarship, and education by publishing worldwide.

It also includes a series of procedures designed to standardize test performance. Jorgensen, PhD, chairholder of the CLSI working group clsi m45-a2 developed the document, it has long been accepted that for the most effective management of bacterial infections, laboratories must clsi m45-a2 able to determine susceptibility or resistance to therapeutic agents.

Not Logged In Member?: The performance, applications, clsi m45-a2 limitations of the current CLSI-recommended methods are described. Jorgensen theorizes that diagnostic device companies may even modify their products to gain regulatory eg, FDA clearance for marketing to clinical laboratories. Oxford University Press is a department of the University of Oxford. View all product details.

Susceptibility testing is especially necessary if the etiological agent is resistant, or possibly resistant, to a commonly used antimicrobial agent.

M45 addresses the modifications required to test these organisms and provides expert guidance on how to interpret results, including identifying the essential breakpoints.

Full Description If a bacterial pathogen’s susceptibility to antimicrobial agents cannot be predicted based on clsi m45-a2 identity of the organism alone, in vitro antimicrobial susceptibility testing of the isolated organism may be indicated.

Jorgensen and Hindler both agree that this revised guideline is very timely, in light of the increasingly common challenges faced by laboratories performing susceptibility clsi m45-a2 on these organisms, including increased pressure from clinicians to provide susceptibility data quickly, and the need for reliable methods to identify emerging resistance.

His e-mail address is glenmcdan aol. In such cases, in vitro antimicrobial susceptibility of the organism isolated is most likely indicated. However, in cases such as those involving fastidious and infrequently isolated organisms for which specific guidelines do not exist, laboratorians have resorted to various alternative methods and applied breakpoints from other groups of organisms.

However, there are instances in which the sensitivity of such a pathogen cannot be predicted simply based on the identity of the clsi m45-a2. These methods may also be used to evaluate commercial clsi m45-a2 for routine use. Before the publication of this guideline, a review of the literature revealed very few systematic studies on testing these organisms, Dr. These organisms include Helicobacter pyloriVibrio choleraeand potential agents of bioterrorism, adds Hindler.

Commercial susceptibility testing devices are not specifically addressed by M Jorgensen identifies these developments as the most obvious benefits of M While comprehensive, the guideline is not prescriptive, and allows some degree of customization of criteria and policies by each laboratory and its medical staff.

Clsi m45-a2 guideline is based somewhat on standardized procedures in other documents, but contains specific instructions on when clsi m45-a2 how to perform antimicrobial susceptibility testing of fastidious or infrequently isolated organisms that clsi m45-a2 be resistant to clsi m45-a2 commonly prescribed through antibiotics.

Susceptibility testing is particularly necessary in those situations in which the etiological agent belongs to a bacterial species for which resistance to commonly used antimicrobial agents has been documented, or could arise. M45 does not suggest that clsi m45-a2 test all infrequently encountered or fastidious isolates, especially if they are of dubious clsi m45-a2 significance, Dr.

The Experts James H. Therefore, laboratories need specific guidelines on how to perform valid susceptibility testing without using the US Food and Drug Administration FDA -cleared clsi m45-a2 and commercial test systems found in most laboratories. For some of the organisms, a disk diffusion method is described, and this method can be easily adopted by most clinical laboratories performing disk diffusion testing.
