GENETIC MARKER FOR DETERMINING PATHOGENICITY OF STREPTOCOCCUS INIAE AND KIT FOR EXAMINING DETERMINANT MARKERS OF PATHOGENICITY BY USING PEPTIDE NUCLEIC ACID

摘要

The present invention relates to a probe for determining a genotype of Steptococcus iniae, the probe being capable of hybridizing, under strict conditions, with a sequence fragment containing a single nucleotide polymorphism variation of T368C or T385G in the cpsD sequence, which is represented by SEQ ID NO: 1, of Streptococcus iniae and, more particularly, to a kit which allows each genotype influencing pathogenicity to have different melting temperature by using a peptide nucleic acid (PNA) having an excellent binding ability to DNA, thereby enabling a simple, rapid, and accurate determination of the pathogenicity of S. iniae.
