  • Detection of campylobacter
    Patent number: 5663049
    Abstract: The invention relates to methods of using nucleic acid probes capable of specifically hybridizing to rRNA of Campylobacter jejuni, C. coli and C. laridis and not to rRNA or rRNA genes of Pseudomonas aeuroginosa, E. coli or Salmonella typhimunium for the detection of Campylobacter in clinical, food and other samples.
    Type: Grant
    Filed: May 30, 1995
    Date of Patent: September 2, 1997
    Assignee: Amoco Corporation
    Inventors: Susan M. Barns, Ray A. McMillian, David J. Lane, Mark L. Collins, James E. Awell, Ayoub Rashtchian
  • Nucleic acid probes and methods for detecting cryptococcus neoformans
    Patent number: 5464743
    Abstract: Nucleic acid probes are described for detecting yeasts capable of causing cryptococcosis, specifically Cryptococcus neoformans. The preferred probes are complementary to the ribosomal ribonucleic acid sequences unique to Cryptococcus neoformans, and as such can detect the rRNA, rDNA, or polymerase chain reaction amplification products of these genes. The detection of the etiological agent of human cryptococcosis, and tests for making a clinical diagnosis of this disease utilizing specific rRNA or rDNA probes are now possible.
    Type: Grant
    Filed: July 1, 1992
    Date of Patent: November 7, 1995
    Assignee: Amoco Corporation
    Inventors: William G. Weisburg, Susan M. Barns
  • Detection of campylobacter with nucleic acid probes
    Patent number: 5447848
    Abstract: Nucleic acid probes capable of specifically hybridizing to rRNA of Campylobacter jejuni, C. coli and C. laridis and not to rRNA or rRNA genes of Pseudomonas aeuroginosa, E. coli or Salmonella typhimunium are described along with methods utilizing such probes for the detection of Campylobacter in clinical, food and other samples.
    Type: Grant
    Filed: July 7, 1988
    Date of Patent: September 5, 1995
    Assignee: AMOCO Corporation
    Inventors: Susan M. Barns, Ray A. McMillian, David J. Lane, Mark L. Collins, James E. Awell, Ayoub Rashtchian
  • Nucleic acid probes for the detection of Neisseria gonorrhoeae
    Patent number: 5432271
    Abstract: Nucleic acid probes capable of hybridizing to rRNA sequences of Neisseria gonorrhoeae and not to rRNA sequences of non-Neisseria gonorrhoeae are described along with methods utilizing such probes for the detection of Neisseria gonorrhoeae in clinical and other samples.
    Type: Grant
    Filed: May 25, 1993
    Date of Patent: July 11, 1995
    Assignee: Amoco Corporation
    Inventors: Susan M. Barns, Donald N. Halbert, David J. Lane
  • Nucleic acid probes and methods for detecting pathogenic candida yeasts
    Patent number: 5403710
    Abstract: Nucleic acid probes are described for detecting yeasts capable of causing Candida infection, specifically yeasts of the genera Candida, Torulopsis, and Yarrowia. The preferred probes are complementary to ribonucleic acid sequences unique to specific Candida species, or groups of such species, and as such can detect the rRNA, rDNA, or polymerase chain reaction amplification products of these genes. Methods for detecting the etiological agent of human Candida fungemia utilizing these probes are also provided.
    Type: Grant
    Filed: June 11, 1993
    Date of Patent: April 4, 1995
    Assignee: Amoco Corporation
    Inventors: William G. Weisburg, Susan M. Barns, David J. Lane, Jeffrey F. Lemontt
  • Nucleic acid probes and methods for detecting fungi
    Patent number: 5324632
    Abstract: Nucleic acid probes are described for detecting fungi capable of causing fungal septicemia or capable of causing food spoilage. The preferred probes are complementary to ribonucleic acid sequences found in numerous fungi and absent in animal or plant genomes. As such, these probes can detect the rRNA, rDNA, or polymerase chain reaction amplification products from the majority of fungal species. The detection of etiological agents of human fungemia, the clinical diagnosis of this disease and the direct evaluation of food or beverage fungal content utilizing rRNA or rDNA probes is now possible.
    Type: Grant
    Filed: October 22, 1991
    Date of Patent: June 28, 1994
    Assignee: Amoco Corporation
    Inventors: William G. Weisburg, Susan M. Barns, Dale A. Pelletier, Mitchell L. Sogin
  • Method for the detection of Neisseria gonorrhoeae
    Patent number: 5217862
    Abstract: Nucleic acid probes capable of hybridizing to rRNA sequences of Neisseria gonorrhoeae and not to rRNA sequences of non-Neisseria gonorrhoeae are described along with methods utilizing such probes for the detection of Neisseria gonorrhoeae in clinical and other samples.
