Molecular identification of bacteria of genus less thanigreater thanstreptococcusless than/igreater than and related genuses

摘要

The rpoB gene (I), and its fragments, of the genera Streptococcus, Enterococcus, Gemella, Abiotrophia and Granulicatella, comprising any of 28 sequences (II), reproduced (some degenerate), are new. Independent claims are also included for the following: (1) oligonucleotides (ON) containing at least 12 consecutive nucleotides (nt) from sequences (S6) or (S7), or the reverse sequences or their complements; (2) equimolar mixture of 16 or 4 ON: (a) containing at least 18, preferably 20, consecutive nt present in (S6); or (b) at least 21, preferably 23, consecutive nt present in (S7), where N = A,C,G,T in the mixture of 16 ON or inosine in the mixture of 4 ON; (3) detecting bacteria of the specified genera by molecular identification that uses (I) or its fragments, or at least one ON; and (4) kit for method (3) containing at least one ON, a mixture of ON or a fragment of (I). 5'-AARYTNGGMCCTGAAGAAAT (S6) 5'-TGNARTTTRTCATCAACCATGTG (S7) N = inosine or any of A, T, C or G; R = A or G; Y = C or T; M = A or C.
