Microbiology Test Method Guides

Please choose a test method guide either by organism or generic test type:


Chromogenic Media

Microbiological Analysis using Chromogenic and Fluorogenic MediaKey PointsInitially developed for clinical applications, chromogenic media are now available for food, water and environmental samples.They can allow enumeration, detection, presumptive identification sometimes even full identification from an isolation plate. What are chromogenic / fluorogenic media?Chromogenic and fluorogenic media are microbiological growth

Clean Rooms

Aspects of the Microbiology of Clean RoomsKey Pointsready to use specially packaged media are available for environmental monitoringtrending of monitoring data helps set action and alert levelspinpointing contamination sources is vital A clean room is an environment where the levels of airborne contaminants are controlled to conform to specifications detailing

Clostridium difficile Detection and Identification

Clostridium difficile is the commonest identifiable cause of antibiotic associated diarrhea (AAD), this review looks at rapid detection and identification methods for C. difficile.

Colony Counts

Counting Techniques in Microbiology: Getting From a Single Cell to Usable DataKey PointsCounting microorganisms allows an estimation of the microbial population in a variety of products.From this a prediction of the life of the product to be applied (product spoilage).Product safety issues are not directly addressed by total

Concentration Techniques for Bacterial Cells

Separation and Concentration of Microorganisms from Food MatricesKey PointsRapid pathogen tests are not sensitive enough to detect very low numbers of cells in food without an initial separation and concentration procedureTraditional enrichment culture methods are effective, but time consuming, often requiring several days to completeDevelopment of rapid separation and concentration

Cronobacter sakazakii Detection and Identification Methods

Review of test kits for detection and identification of Cronobacter sakazakii previously called Enterobacter sakazakii, a common microbiological problem in infant formula.

Cryptosporidium/Giardia Detection and Identification Methods

Review of how to detect Cryptosporidium and Giardia in water. Very large sample volumes and effective concentration procedures are needed to detect the very low numbers of protozoan cysts likely to be present.

Detection of Allergens in Foods and Processing Areas

IntroductionFood allergens are proteinaceous agents in foods that can trigger adverse immune reactions in certain people. Most of these reactions are mild and require no treatment. However, severe reactions can occur resulting in anaphylactic shock or even death. The symptoms vary depending on the type of food and the immune

Detection of Bacterial Toxins in Food

Kits for detection of bacterial toxins in foods - C. botulinum, Bacillus cereus and Staphylococcal toxin can be detected by ELISA, RPLA and lateral flow assays.

Dry Sample-ready Plates Are Ideal Alternative to RMMs

Introduction For the routine food and water microbiology lab Rapid Microbiological Methods (RMM) have been available for many years, normally RMM are considered to be non-culture based techniques such as immunoassays or molecular methods. If a lab is not yet using RMMs, most likely the available technologies do not meet
