摘要:
The present invention provides methods for rapid forensic investigations by identification of bioagents associated with biowarfare and acts of terrorism or crime. The methods are also useful for epidemiological investigations by genotyping of bioagents.
摘要:
The present invention relates generally to the field of investigational bioinformatics and more particularly to secondary structure defining databases. The present invention further relates to methods for interrogating a database as a source of molecular masses of known bioagents for comparing against the molecular mass of an unknown or selected bioagent to determine either the identity of the selected bioagent, and/or to determine the origin of the selected bioagent. The identification of the bioagent is important for determining a proper course of treatment and/or irradication of the bioagent in such cases as biological warfare. Furthermore, the determination of the geographic origin of a selected bioagent will facilitate the identification of potential criminal identity.
摘要:
Method for detecting and identifying unknown bioagents, including bacteria, viruses and the like, by a combination of nucleic acid amplification and molecular weight determination using primers which hybridize to conserved sequence regions of nucleic acids derived from a bioagent and which bracket variable sequence regions that uniquely identify the bioagent. The result is a “base composition signature” (BCS) which is then matched against a database of base composition signatures, by which the bioagent is identified.

The present invention provides design and synthesis of oligomeric compounds and compositions that can be administered to reduce the activity of SARS virus in vivo or in vitro, to prevent or treat SARS virus-associated disease, to detect AARS virus, and to diagnose SARS virus-associated diseases.
摘要:
Polynucleotides comprising molecular interaction sites of 16S rRNA that have particular secondary structure are provided. Methods of using such polynucleotides to screen, virtually or actually, combinatorial libraries of compounds that bind thereto are also provided. Method of modulating the activity of 16S rRNA by contacting 16S rRNA or prokaryotic cells containing the same with a compound identified by such virtual or actual screening are also provided.

Oligonucleotide primers and compositions and kits containing the same for rapid identification of orthopoxviruses by amplification of a segment of viral nucleic acid followed by molecular mass analysis are provided.
摘要:
The present invention provides a method for rapid identification and quantitation of bacteria by amplification of a segment of bacterial nucleic acid followed by analysis by mass spectrometry. The compositions provide for characterization of the molecular masses and base compositions of bacterial nucleic acids which are used to rapidly identify bacteria.
摘要:
The method described herein relate generally the identification of bioagents on the basis of base composition signatures for bioagent-identifying amplicons. Specifically, methods of the present invention are directed to the application of pattern recognition models, particularly probability pattern classifiers, to the identification of both known and previously unrecognized bioagents. In certain embodiments, the pattern classifiers relate to probability cloud patterns, such as mutational probability patterns. In other embodiments the pattern classifiers relate to polytope pattern models.
摘要:
Methods of identifying molecular interaction sites in eukaryotic and prokaryotic nucleic acids, especially RNA, are described. Secondary structural elements are identified from highly conserved sequences. Methods of preparing databases relating to such molecular interaction sites are also provided herein as are databases themselves. Therapeutic, agricultural, industrial, and other applicability results from interaction of such molecular interaction sites with “small” and other molecules.
