  • Rapid detection of mold by accelerated growth and detection
    Patent number: 9580760
    Abstract: The invention includes a method of detecting the presence or absence of mold in a sample. The method can include the step of applying a sample suspected of containing the mold to a growth medium, optionally fragmenting the sample, associating the sample with a labeling agent, and detecting the presence or absence of the mold by detection of the labeling agent. The invention can also include a medium for growing mold that includes a stimulation agent.
    Type: Grant
    Filed: March 28, 2007
    Date of Patent: February 28, 2017
    Assignee: Becton, Dickinson and Company
    Inventors: Angela M. Oppedahl, Steven J. Lasky, Dylan D. Baker, Daniel Buttry, Ann M. Steger
  • SIMULTANEOUS RAPID DETECTION OF MICROBES
    Publication number: 20080261229
    Abstract: The invention includes a method of simultaneously detecting the presence or absence of more than one microbe class (e.g., bacteria, yeast, and mold) in a sample. The method can include the step of applying a sample suspected of containing more than one microbe class to a growth medium, optionally fragmenting the sample, associating the sample with a labeling agent, and simultaneously detecting the presence or absence of each microbe class by detection of the labeling agent.

  • Isospora suis sporozoite antigen
    Patent number: 5861160
    Abstract: Isospora suis is propagated using a swine testicular cell line which facilitates production of sporozoites and merozoites, either or both of which can be used in a vaccine for swine. Antibodies against Isospora suis sporozoites, which inhibit the infectivity of the sporozoites for the swine testicular cells, were made. These neutralizing antibodies were used to identify an apparent sporozoite attachment protein and cloned cDNA encoding a portion of the protein. The cloned cDNA was sequenced and the corresponding amino acid sequence of the antigenic sporozoite protein revealed two areas having repeated amino acid sequences, which may likewise be used in a vaccine.
