Inhibition of the PCR may be suspected if the expected amplicon is obtained from the positive control sample containing C. m. subsp. sepedonicus in water but negative results are obtained from positive controls with C. m. subsp. sepedonicus in potato extract.
PCR inhibeerimist võib kahtlustada siis, kui oodatav amplikon saadakse positiivse kontrolli proovist, mis sisaldab bakterit C. m. subsp. sepedonicus vees, kuid negatiivseid tulemusi saadakse positiivsetest kontrollidest, mis sisaldavad bakterit C. m. subsp. sepedonicus kartuliekstraktis.
