Escherichia coli O.157:H7 and Escherichia coli O.157 (non-VTEC) give a false negative result for Escherichia coli on the CCA and TBX because the colonies do not appear characteristic. Colonies of Escherichia coli appear on CCA (Chromogenic Coliform Agars) as dark-blue to violet colonies. However, Escherichia coli O.157:H7 doesn’t do this and gives red colonies. Colonies of …

Quality in Control

Microbiological laboratories should be able to receive reliable analysis without much overhead. A microbiological analyst must be able to focus on the primary activities, for example analysis of the sample material. Quality control should support the analyst in a logical and simple manner. By using modern information technology, process control and quality assurance are designed smarter and more effective.
