  • Patent number: 5994067
    Abstract: In one aspect of the invention there is described a method of detecting the presence of toxins, which may traverse bacterial membranes in some manner, in environmental samples using an indicator bacteria such as E. coli K-12 and a fluorescent signal. The method includes:(a) obtaining a positive control signal by placing an indicator bacteria strain such as E. coli K-12 and a bactericidal peptide such as a cecropin in a suitable buffer containing a fluorescent marker for bacterial DNA such as SYTOX;(b) obtaining a negative control signal by placing only the indicator bacteria strain in the buffer containing the fluorescent marker for bacterial DNA;(c) obtaining a test signal by combining an environmental test sample with the indicator bacteria strain and the fluorescent marker for bacterial DNA in the buffer; and(d) comparing the signal generated by the test sample to that obtained for the negative control.
