Abstract:
Polymerase chain reaction (PCR) for the identification of C.botulinum of type A was developed. As primers, oligonucleotides corresponding to sequences 913 -- 932 and 1852 -- 1871 of the gene of type A botulinic neurotoxin were used. The study revealed that under optimum conditions the positive result of the reaction was registered only when the DNA of C.botulinum strains of type A (11 strains) was used, but not that of C.botulinum strains of other types (11 strains of type B, 5 strains of type C, 2 strains of type D, 6 strains of type E and 1 strain of type G). High sensitivity, specificity and rapidity of PCR open good prospects for its practical use.
