Antibiotic susceptibility testing using probes for preribosomal RNA
First Claim
1. A device for detecting intact pre-rRNA in a bacterial sample, the device comprising a pair of oligonucleotide probes, at least one of which is immobilized on a solid support, wherein the pair of oligonucleotide probes comprises an oligonucleotide probe up to 50 nucleotides in length that includes SEQ ID NO:
- 5 and an oligonucleotide probe up to 50 nucleotides in length that includes SEQ ID NO;
6, and wherein the pair of oligonucleotide probes selectively hybridizes to a target sequence specific to intact pre-rRNA, wherein the target sequence comprises contiguous nucleotides of bacterial ribosomal RNA (rRNA) spanning a splice site between pre-ribosomal RNA (prRNA) tail and mature ribosomal RNA (mrRNA).

Abstract
Described are probes and methods for detecting antibiotic susceptibility of a specimen. The method comprises contacting the specimen with an oligonucleotide probe that specifically hybridizes with a target nucleic acid sequence region of ribosomal RNA. The target sequence is at the junction between a pre-ribosomal RNA tail and mature ribosomal RNA of 23S or 16S rRNA. Performing the method in the presence and absence of an antibiotic permits detection of antibiotic susceptibility.
