In only43.7 per cent, of 379 strains of Ps.pyocyanea were the results identical by the two methods.A higher correlation was noted in the case of Sh. sonnei and only 6 out of 89 strains of thisspecies gave different results by the two methods. We cannot recommend the use of cellulose acetate membranes in these bacteriocine typing techniques., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-2-2-161
