Cronobacter spp. ChromoSelect Agar is recommended for the isolation and identification of Cronobacter spp. from milk and milk products.

Preparation Note

Suspend 30.75 g in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 15 Ibs pressure (121°C) for 15 minutes. Cool to 45-50°C and pour into sterile petri plates.

This study evaluates the potential of continuous wave Ultraviolet C light (UV-C) and broad-spectrum intense pulsed light (in this study referred to as High Intensity Light Pulses, HILP) for the inactivation of pathogens of public concern in powdered infant formula

Articles

Cronobacter spp. are frequently found on vegetables, meat, fermented bread, dairy and in baby food. Consumption of contaminated powdered infant formula milk can result in sepsis, infant meningitis and necrotizing enterocolitis.

Selective media enable faster results and visual confirmation for the detection, identification, and enumeration of microorganisms

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
