A method for preparing probes, as well as several probes for use in qualitative or quantitative hybridization assays are disclosed. The method comprises constructing an oligonucleotide that is sufficiently complementary to hybridize to a region of rRNA selected to be unique to a non-viral organism or group of non-viral organisms sought to be detected, said region of rRNA being selected by comparing one or more variable region rRNA sequences of said non-viral organism or group of non-viral organisms with one or more variable region rRNA sequences from one or more non-viral organisms sought to be distinguished. Hybridization assay probes for Mycobacterium avium, Mycobacterium intracellulare, the Mycobacterium tuberculosis-complex bacteria, Mycoplasma pneumoniae, Legionella, Salmonella, Chlamydia trachomatis, Campylobacter, Proteus mirabilis, Enterococcus, Enterobacter cloacae, E. coli, Pseudomonas group I, Neisseria gonorrhoeae, bacteria, and fungi also are disclosed.
The present application is a divisional of Hogan et al., U.S. application Ser. No. 08/200,866, filed Feb. 22, 1994, now U.S. Pat. No. 5,541,308 which is file wrapper continuation of Hogan et al., U.S. application Ser. No. 07/806,929, filed Dec. 11, 1991, now abandoned, which is a file wrapper continuation of Hogan et al., U.S. Ser. No. 07/295,208, filed Dec. 9, 1988, now abandoned, which was the National filing of PCT/US87/03009, filed Nov. 24, 1987, which is a continuation-in-part of Hogan et al., U.S. application Ser. No. 07/083,542, filed Aug. 7, 1987, now abandoned, which is a continuation-in-part of Hogan et al., U.S. Ser. No. 06/934,244, filed Nov. 24, 1986, now abandoned, the entirely of each of these prior applications including drawings are hereby incorporated by reference herein.
The invention provides methods to detect Legionella and further to detect L. pneumophila in biological samples using real-time PCR. Primers and probes for the detection of Legionella and L. pneumophila are provided by the invention. Articles of manufacture containing such primers and probes for detecting Legionella and L. pneumophila are further provided by the invention.
