a
−, negative PCR result for primer pair noted at top of column; +, positive PCR result for primer pair noted at top of column. The PL60/PL61 primer pair specifically amplify a 417-bp PCR product in nonlysogenic strains and result in no PCR product in lysogenic strains. The PL14/PL61 primer pair specifically amplify a 743-bp PCR product in lysogenic strains and result in no PCR product in nonlysogenic strains.
