Abstract
Nucleic acid probes capable of hybridizing to rRNA of eubacteria and not to rRNA of non-eubacteria are described along with methods utilizing such probes for the detection of eubacteria in clinical and other samples. Preferred embodiments include probes capable of distinguishing between gram-positive and gram-negative bacteria.
Claims3
A method of detecting the presence of eubacteria in a sample comprising:
- a) contacting said sample with at least one nucleic acid probe selected from the group of probes consisting of 1661, 1739, 1746, 1743, 1639, 1640, 1641, 1656, 1657, 1653, 1654, 1655, 1651, 1652, 1595, 1600, 1601, 1602, 1598, 1599, 1596, and 1597, under conditions that allow said probe to hybridize to rRNA or rDNA of said eubacteria, if present in said sample, to form hybrid nucleic acid complexes, which fragments do not form hybrids with rRNA or rDNA of mouse L cells, wheat germ, human blood, or Candida albicans;
- and
- b) detecting said hybrid nucleic acid complexes as an indication of the presence of said eubacteria in said sample.
