Abstract:
The present invention provides methods of detecting a biothreat agent in a sample, comprising detecting at least one biothreat-specific amplicon in the sample. The methods also encompass confirming the absence of the biothreat agent by detecting Near Neighbor specific amplicons to avoid false positive results.
Abstract:
Embodiments of the invention include methods of identifying microorganisms and/or diagnosing infections in subjects cause by microorganisms. Embodiments of the invention may also include further characterizing (e.g., determining the presence of one or more antibiotic resistance markers) the microorganisms and determining a strain identity of the microorganisms.
Abstract:
The present invention relates to method of detecting and characterizing one or more Borrelia species causing Lyme Disease or tick-borne relapsing fever within a sample from a subject, the method comprising: a) subjecting DNA and/or RNA from the sample to a PCR amplification reaction using primer pairs targeting at least one region of Borrelia 16S rRNA and at least one region of flaB , ospA, ospB , ospC , glpQ , 16S-23S intergenic spacer (IGS1), 5S-23S intergenic spacer (IGS2), bbk32 , dbpA , dbpB , and/or p66 ; and b) analyzing amplification products resulting from the PCR amplification reaction to detect the one or more Borrelia species.
Abstract:
The present invention provides multiplex assays, methods and kits that may be used to detect and confirm the presence of MRSA in a sample. The methods include real-time PCR assays, and the kits and compositions include oligonucleotides used as primers and probes. The present invention further comprises assays useful to identify and differentiate MRSA, MSSA, MRSE, MSSE, MRCNS and MSCNS in a sample.
Abstract:
Methods, kits, and oligonucleotides used in the detection of the coronavirus strain, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are disclosed. In some aspects, the oligonucleotides are primers or probes used in the described methods or kits. The oligonucleotide consists of 42 or less nucleotides and has a nucleotide sequence that consists essentially of, or is a variant of, the nucleotide sequence of: SEQ ID NO: 1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:6, or SEQ ID NO:7. In some embodiments, the oligonucleotide is modified with an internal spacer or a detectable label. For example, the 5' terminus is labeled with a fluorophore and the 3' terminus is complexed to a quencher of fluorescence of said fluorophore. In some embodiments, the nucleotide sequence of the oligonucleotide further comprises a universal tail sequence.

Abstract:
Some embodiments of the invention include a method of preparing a sample for sequencing that includes receiving a sample and amplifying at least one marker within the sample. In some embodiments, amplification of the first marker may include mixing the sample with a first oligonucleotide that comprises a first universal tail sequence and a second oligonucleotide that comprises a second universal tail sequence. In some aspects of the invention, the first universal tail sequence and the second universal tail sequence are different sequences.
