It is the main prey of the T4 phage, and it was grown in a medium containing ammonium chloride in the Meselson-Stahl experiment to show the semiconservative nature of DNA.
IDEXX Defined Substrate Technology is able to show its presence when beta-glucuronidase metabolizes 4-methylumbelliferyl-beta-D-glucuronide to produce fluorescence. Tani, et al. showed that its persistence in sediment of urban streams and Juncosa showed that native Guyanians developed resistant strains of it by exposure to a drug chemically similar to ciprofloxacin.

For 10 points, name this gram-negative bacteria, whose virulent forms such as 0157:H7 produce shigatoxins and are a danger to humans through fecal contamination of food and water.
