Patent number: 7632508Abstract: Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an immune response to PIV or other pathogens. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different pathogen, including different PIV virus to form the human-bovine chimeric PIV genome or antigenome.Type: GrantFiled: January 4, 2006Date of Patent: December 15, 2009Assignee: The United States of AmericaInventors: Alexander C. Schmidt, Mario H. Skiadopoulos, Peter L. Collins, Brian R. Murphy, Jane E. Bailly, Anna P. Durbin

Patent number: 7622124Abstract: The invention provides an improved Mycoplasma hyopneumoniae bacterin vaccine composition, which advantageously provides immunity from infection after a single administration. The composition comprises an inactivated Mycoplasma hyopneumoniae bacterin and an adjuvant mixture, which, in combination, provide immunity from Mycoplasma hyopneumoniae infection after a single administration, and elicit an immune response specific to Mycoplasma hyopneumoniae bacterin and including cell-mediated immunity and local (secretory IgA) immunity. In a preferred embodiment, the adjuvant mixture comprises an acrylic acid polymer, most preferably CARBOPOL®, and a mixture of a metabolizable oil such as one or more unsaturated terpene hydrocarbons, preferably squalene or squalane, and a polyoxyethylene-polypropylene block copolymer such as PLURONIC®. The vaccine composition may optionally include a preservative, preferably thimerosol and/or EDTA.Type: GrantFiled: January 11, 2007Date of Patent: November 24, 2009Assignee: WyethInventors: Hsien-Jue Chu, Wumin Li, Zhichang Xu

Publication number: 20090280142Abstract: A method of detecting osteoporosis in a mammalian is disclosed herein which includes: a) obtaining a sample of a bone related tissue or cells; and b) measuring the concentration of at least a marker which is either bacteria, bacteria produced factors, or HSPs. The method may further include comparing the concentration with concentrations from the same individual over a period of time or against a standard concentration. The marker may be a bacteria, a chaperone molecule, or a bacteria produced. Also provided herein is a method of treating or preventing osteoporosis caused by a bone disease which includes administering to a mammalian subject a therapeutically effective amount of a formulation which is either an HSP antigenic formulation or a bacterial antigenic formulation. The osteoporosis can be caused by a bone disease induced by bone infectious agents such as viruses, bacteria, fungi, protozoa and parasites.Type: ApplicationFiled: May 18, 2009Publication date: November 12, 2009Applicant: DEPUY MITEK, INC.Inventors: Kai-Uwe Lewandrowski, Debra J.
