  • Method for rapidly detecting quinolone-resistant Salmonella ssp. and the probes and primers utilized therein
    Publication number: 20070031889
    Abstract: The present invention relates to a method for rapidly detecting quinolone-resistant Salmonella spp. The invention also relates to the oligonucleotide primers and probes utilized in the method, which can differentiate mutant strains having one or two single point mutations in gyrA gene or single point mutation in parC gene from wild type strains, respectively. Said primers and probes can be effectively used for detection of nalidixic acid-resistant and/or ciprofloxacin-resistant Salmonella strains.

  • Probiotic Bifidobacterium strain
    Patent number: 5922375
    Abstract: Disclosed herein is a Bifidobacterium strain isolate that is incorporated into food, beverages, animal feeds, and/or dietary supplements. It can be used to provide a healthful bacteria to human adults and non-human mammals. The bacterium acts as a probiotic. For example, the bacterium assists newborns in producing protective acetic acid and lactic acid, as well as antimicrobials and vitamins. The bacterium can also be used to reseed bacteria levels caused by diarrhea, chemotherapy, advancing age, antibiotics, or other causes.
