Microbial Identification - a rapidmicrobiology Special Focus


What's in a name? Microbiology labs spend a lot of time and resources into putting a name to bacteria and fungi, in some instances this task is a regulatory requirement (such as CCS in Annex 1) but normally it's because it delivers insight data that will highlight potential risks, or suggest appropriate therapies, or to track and trace incidence. Whether it's just a general classification or a detailed molecular analysis, find the right solution for your lab on this rapidmicrobiology special focus page, and explore options for the identification of microorganisms in routine clinical, food, or pharmaceutical labs.

Traditionally, microbial identification was based on morphology combined with biochemical tests, these tests involved analysis of various metabolic activities of microorganisms, such as how they metabolised sugars etc. Thermo Fisher has prepared two SmartNotes one for clinical labs and one for industrial labs to explain why manual biochemical testing is still critical for all microbiology labs even if they have an automated system in place.

Incorporating biochemical reagents or chromogens into culture media so they produce particular colours in the presence of enzymes specific to a target group of organisms is an easily accessible, cost-effective approach. The CondaLab CondaChrome® range offers a wide choice of chromogenic media for both food safety and clinical applications. Plus there is the option of identifying different species of the same bacterial group in the same culture medium, revealing the presence of additional genera in the sample. Available for download are Bio-rad's popular reference guides to various methods including their chromogenic media and PCR kits both with applications for detecting a range of quality indicators and pathogens in food, water, and environmental samples.

Latex agglutination kits are a fast, and easy approach for confirmatory identification, Gold Standard Diagnostics has launched Microgen rapid latex agglutination tests, to instantly confirm the identification of Salmonella, Legionella, or Staphylococcus aureus colonies in food and environmental samples.

Increasingly found in many labs is Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) where particles are ionized, separated according to their mass-to-charge ratio, and measured by determining the time it takes for the ions to travel to a detector at the end of a time-of-flight tube. The results are compared to a database of spectra from known organisms. The VITEK MS PRIME is a benchtop high-throughput automated identification system designed to meet the pharmaceutical industry’s needs. Thanks to its robust database, this solution identifies a wide variety of microorganisms including bacteria, yeast, fungi, and mycobacteria.

Traditional microbiology methods enable detection only of a subset of microbes in a sample (only those organisms that can be cultured under laboratory conditions). Metagenomics overcomes this limitation by directly extracting and sequencing DNA or RNA from samples by NGS, thus providing a snapshot of the genetic content of the entire microbial community. Discover PCR Biosystems' VeriFi™ Library Amplification Mix can help ensure an accurate representation of microbial diversity.

Confused with all the different sequencing technologies? Charles River traces the history of DNA sequencing from its first foundation through Sanger, 16S RNA, Next-generation sequencing (NGS), WGS, Nanopore sequencing (ONT) to Strain Typing by Molecular Subtyping (SLST/MLST).
