    Abstract: Monoclonal antibody reagents that recognize the SARS-coronavirus (SARS-HCoV) are needed urgently. In this report we describe the development and immunochemical characterisation of mAbs against the SARS-HCoV based upon their specificity, binding requirements, and biological activity. Initial screening by ELISA, using highly purified virus as the coating antigen, resulted in the selection of seventeen mAbs. Five mAbs exhibited Western immunoblot reactivity with the denatured spike protein, of which two demonstrated the ability to neutralize SARS-HCoV in vitro. Another four Western immunoblot-negative mAbs also neutralize the virus. These antibodies will be useful for the development of diagnostic tests, pathogenicity and vaccine studies.

  • Publication number: 20020098573
    Abstract: An infectious clone based on the genome of a wild-type RNA virus is produced by the process of providing a host cell not susceptible to infection by the wild-type RNA virus, providing a recombinant nucleic acid based on the genome of the wild-type RNA virus, transfecting the host cell with the recombinant nucleic acid and selecting for infectious clones. The recombinant nucleic acid comprises at least one full-length DNA copy or in vitro-transcribed RNA copy or a derivative of either. The infectious clones can be used in single or dual purpose vaccines and in viral vector vaccines.

  • Patent number: 6368603
    Abstract: Disclosed and claimed are compositions containing a Borrelia burgdorferi antigen, and methods for making and using them. The antigen can be OspA. The compositions can contain at least one additional antigen from a pathogen other than Borrelia burgdorferi. The compositions are useful for eliciting an immunological response in a host mammal susceptible to Lyme Disease and to the mammalian pathogen other than Borrelia burgdorferi. Suitable host mammals include dogs, pups, horses, and, the additional antigen can be of a canine, equine or feline pathogen, such as rabies, canine distemper, adenovirus, coronavirus, parainfluenza and parvovirus. No significant efficacy interference is observed.
