The present invention relates to the detection of a target nucleic acid sequence by a PTOCE (PTO Cleavage and Extension) assay. The present invention detects a target nucleic acid sequence in which the PTO (Probing and Tagging Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved to release a fragment and the fragment is hybridized with the CTO (Capturing and Templating Oligonucleotide) to form an extended duplex, followed by detecting the presence of the extended duplex. The extended duplex provides signals (generation, increase, extinguishment or decrease of signals) from labels indicating the presence of the extended duplex and has adjustable T.sub.m value, which are well adoptable for detection of the presence of the target nucleic acid sequence.

Methods for the rapid detection of the presence or absence of Epstein Barr Virus (EBV) in a biological or non-biological sample are described. The methods can include performing an amplifying step, a hybridizing step, and a detecting step. Furthermore, primers and probes targeting EBV, and kits are provided that are designed for the detection of target regions of EBV. Also described are kits, reaction mixtures, and oligonucleotides (e.g., primer and probe) for the amplification and detection of EBV. Also described are primers and probes that detect different regions of EBV, and can be employed in a dual target assay for simultaneously detecting two different and non-overlapping target regions of EBV.

The present invention relates to the detection of a target nucleic acid sequence by a PTOCE-E (PTO Cleavage and Extension-dependent Extension) assay. The PTOCE-E assay of the present invention can reduce the non-target signal and increase the target signal as compared with the conventional PTOCE and PCE-SH methods, thereby enabling more accurate detection of the target nucleic acid sequence.

The present invention relates to compositions and methods for the use of polymerase chain reaction (PCR) as a reporter assay for rapid and simultaneous bacterial identification and phenotype testing for antimicrobial susceptibility (AST). The current invention uses a strategy that has shown the ability for multiplexing and for handling polymicrobial samples for antimicrobial susceptibility testing.

Specific, accurate, and cost effective primers for performing digital PCR, compositions and kits containing the primer and methods for using and making the same are useful for detecting nucleic acid mutations. A primer useful as a first forward primer in performing digital PCR to detect a target nucleic acid in a sample, includes: a detection portion located upstream to a target sequence binding portion, and including a second forward primer binding portion having a sequence substantially complementary to a second forward primer, and a probe binding portion downstream to the second forward primer binding portion having a sequence substantially complementary to a probe; the target sequence binding portion includes a mismatch portion having a sequence not complementary to the target nucleic acid, and an amplification determinant portion downstream to the mismatch portion having a sequence complementary to a gene allele or a variant thereof encoded by the target nucleic acid.
