There has been increasing demand for rapid, sensitive and specific detection of Escherichia coli as an indicator of possible pathogen contamination in foods and water. Approximately 97% of E. coli strains produce ?- glucuronidase (GUS), which could p

From 1988 through 1992 Salmonellosis accounted for 27% of the total reported foodborne disease outbreaks and 57% of the outbreaks in which the pathogen was identified. The prevalence of Salmonellosis and the new requirements to monitor the organism a
