Patent number: 9212399Abstract: Disclosed are compositions for isolating populations of nucleic acids from biological, forensic, and environmental samples. Also disclosed are methods for using these compositions as one-step formations for killing pathogens, inactivating nucleases, and releasing polynucleotides from other cellular components within the sample, and stabilizing the nucleic acids prior to further processing or assay. The disclosed compositions safely facilitate rapid sample collection, and provide extended storage and transport of the samples at ambient or elevated temperature without contamination of the sample or degradation of the nucleic acids contained therein. This process particularly facilitates the collection of specimens from remote locations, and under conditions previously considered hostile for presenting the integrity of nucleic acids released from lysed biological samples without the need of refrigeration or freezing prior to molecular analysis.Type: GrantFiled: January 7, 2014Date of Patent: December 15, 2015Assignee: Longhorn Vaccines and Diagnostics, LLCInventors: Gerald W Fischer, Luke T.

Publication number: 20150064198Abstract: The invention is directed to compositions and methods for generating or enhancing the immune system of a patient against infection by a pathogen, and in particular MTB. Compositions of the invention contain one or more non-naturally occurring antigens that generate an effective cellular or humoral immune response to MTB and/or antibodies that are specifically reactive to mycolic acid or to the surface of MTB. The greater activity of the immune system generated by a vaccine of the invention involve an conjugation of peptides to increase in the generation of memory T cells that provide for a greater and/or longer lived or extended response to an MTB infection. Preferably a response involves an increased generation of antibodies that enhance immunity against MTB infection and promote an enhanced phagocytic response.Type: ApplicationFiled: August 29, 2014Publication date: March 5, 2015Inventors: Gerald W. Fischer, Luke T. Daum, Clara Jebet Sei

Publication number: 20150056609Abstract: Disclosed is an enhanced method for rapid and cost-effective analysis of sequences of a microorganism by semi-conductor sequencing, preferably ion-torrent sequencing. This method provides for full length analysis and of multiple areas (e.g. genes) of multiple genomes. These methods identify genetic mutations of a particular gene that are responsible for conferring resistance or sensitivity to an antibiotic or other chemical compound. Multiple different species, strains and/or serotypes of a particular organism are rapidly and efficiently screened and mutations identified along with the complete genome of an organism. By selecting primers pairs of similar size and GC content that produce amplicons with sequences spanning the entire genome, a single PCR reaction analyzed by ion torrent methodology can determine the sequence of a complete genome. Methods are useful to sequences the genomes of viral agents, such as influenza virus, and bacterial agents, such as tuberculosis bacteria.Type: ApplicationFiled: October 29, 2014Publication date: February 26, 2015Applicant: Longhorn Vaccines and Diagnostics, LLCInventors: Luke T.

Patent number: 8372958Abstract: The present invention encompasses monoclonal and chimeric antibodies that bind to lipoteichoic acid of Gram positive bacteria. The antibodies also bind to whole bacteria and enhance phagocytosis and killing of the bacteria in vitro and enhance protection from lethal infection in vivo. The mouse monoclonal antibody has been humanized and the resulting chimeric antibody provides a previously unknown means to diagnose, prevent and/or treat infections caused by gram positive bacteria bearing lipoteichoic acid. This invention also encompasses a peptide mimic of the lipoteichoic acid epitope binding site defined by the monoclonal antibody. This epitope or epitope peptide mimic identifies other antibodies that may bind to the lipoteichoic acid epitope. Moreover, the epitope or epitope peptide mimic provides a valuable substrate for the generation of vaccines or other therapeutics.Type: GrantFiled: June 23, 2003Date of Patent: February 12, 2013Assignee: Biosynexus Incorporated;Inventors: Gerald W.
