Aims: To explain the basis for false negative β-glucuronidase reactions seen with culture media containing lactose as a carbon and energy source. Methods and Results: Escherichia coli strains were assessed for their reactions in culture media contai

Testing for beta-D-glucuronidase activity has become the basis of many methods for the detection of Escherichia coli in both food and water. Used in combination with tests for the presence of beta-D-glucuronidase, these tests offer a simple method fo

The use of standard Colilert (IDEXX) for the detection of coliforms and E. coli in potable water has been studied. In a large survey, Colilbert recovered E. coli from similar numbers of samples to membrane filtration whilst recovery of coliforms was

Two viability substrates, ChemChrome B and 5-cyano-2,3,4-tolyl-tetrazolium chloride (CTC) were compared with the traditional pour plate method for the enumeration of bacteria in potable water samples. ChemChrome B stained cells were counted, on a mem

The polymerase chain reaction has been applied to the detection of Escherichia coli DNA in the upper gut contents of Lindow Man, an Iron Age bog body dated to ca 300 BC. With sets of primers from the uidA and lacZ genes, E. coli DNA could be detected

Aims: Methods for the detection of coliforms in water have changed significantly in recent years with procedures incorporating substrates for the detection of β-d-galactosidase becoming more widely used. This study was undertaken to determine the ra

The use of flow cytometry to detect Cryptosporidium oocysts in water was investigated using a Skatron Argos 100–5 instrument. Raw and treated drinking water samples seeded with oocysts and treated sewage samples known to contain oocysts were analys

The Colilert system presence/absence test and LMX broth were compared for their ability to recover E. coli and coliforms from water. Both methods gave similar recoveries for both groups of organisms. The LMX system, however, gave a significant number

A study of the use of a recently described single membrane medium for the simultaneous enumeration of Escherichia coli and coliforms has shown similar E. coli confirmation rates (92%) for both membrane lauryl sulphate broth (MLSB) and membrane lactos
