Campylobacter Detection and Identification Methods

Review of detection and identification methods for Campylobacter in foods - chromogenic media, rapid methods, PCR kits.

Chromogenic Media

Microbiological Analysis using Chromogenic and Fluorogenic Media Key Points Initially 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

Clean Rooms

Aspects of the Microbiology of Clean Rooms Key Points ready to use specially packaged media are available for environmental monitoring trending of monitoring data helps set action and alert levels pinpointing contamination sources is vital  A clean room is an environment where the levels of airborne contaminants are controlled

Clostridioides difficile Detection and Identification

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

Colony Counts

Counting Techniques in Microbiology: Getting From a Single Cell to Usable Data Key Points Counting 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

Concentration Techniques for Bacterial Cells

Separation and Concentration of Microorganisms from Food Matrices Key Points Rapid pathogen tests are not sensitive enough to detect very low numbers of cells in food without an initial separation and concentration procedure Traditional enrichment culture methods are effective, but time consuming, often requiring several days to complete Development of

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 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
