According to ASM EC broth and agar media with MUG is best suited for confirmatory testing of the presence of E. coli after a presumptive positive result for fecal coliform bacteria. Procedure for MUG Test (b-Glucuronidase test) Prepare a dense milky suspension of the organism to be tested in a small tube containing ml of saline. A single oral dose of chlorpyrifos (10 mg/kg) increased the level of beta-glucuronidase activity in rat blood fold within 2 h (Fujikawa et al., ). The beta-glucuronidase activity decreased to control levels by 24 h. Thus, increased levels of beta-glucuronidase in plasma may serve as . Genetic characterization of the -glucuronidase enzyme from a human intestinal bacterium, Ruminococcus gnavus. The complete nucleotide sequence of a bp DNA fragment containing the beta-glucuronidase locus from R. gnavus E1 was determined. Five ORFs were detected on this fragment: three complete ORFs (ORF2, gus and ORF3) and two partial ORFs.
