This review highlights the challenges associated with
the detection and identification of pathogenic bacteria, by providing an introduction to the techniques currently used, as well as newer techniques that are in development. Focusing on the chemical basis for these techniques, the review also provides a comparison of their advantages and disadvantages.

This is done to increase cell number thereby overcoming problems associated with the sensitivity of classical detection strategies. However, culture—based methods have the disadvantages of taking longer, usually are more complex and require skilled personnel as well as not being able to detect viable but non cultivable microbial species. A number of molecular methods have been developed in the last 10 to 15 years to overcome these issues and to facilitate the rapid, accurate, sensitive and cost effective identification and enumeration of microorganisms which are designed to replace and/or support classical approaches to microbial detection. Amongst these new methods, ones based on the polymerase chain reaction and nucleic acid hybridization have been shown to be particularly suitable for this purpose. This review generally summarizes some of the current and emerging nucleic acid based molecular approaches for the detection, discrimination and quantification of microbes in environmental, food and clinical samples and includes reference to the recently developing areas of microfluidics and nanotechnology "Lab-on-achip".

Rights & Usage This item is part of a JSTOR Collection. What are the traditional basis of detection and identification of pathogenic microorganisms?Traditional approaches for microbial detection and identification include microbial cultivation, immunological (e.g., antibody-based) assays, and nucleic acid detection schemes—especially amplification methods such as PCR (Tang et al., 1997; Fredricks and Relman, 1999).
What is the benefit of using molecular biology techniques for identifying bacteria rather than the traditional way List 3 reasons?Molecular techniques have the advantage that, they are rapid, less laborious, and more sensitive, specific and efficient compared to the conventional method (Magistrado et al.
What are the advantages of molecular diagnosis over the traditional method for detecting infectious diseases?In addition to direct detection from clinical specimens, molecular methods can confirm a positive culture within a day compared to approximately four weeks using phenotypic methods. This has shortened the time for laboratory confirmation of suspected tuberculosis even for smear-negative but culture-positive cases.
What are the advantages of using molecular tests for microbial identification over classical tests?Molecular diagnostic methods have potential advantages in sensi- tivity, specificity, rapidity and cost effectiveness compared to other methods for microbial identification. High specificity allows accu- rate identification and discrimination of microbial strains (even those with similar phenotypic traits).
