  • Publication number: 20240181000
    Abstract: Avian pathogenic bacteria, such as avian pathogenic E. coli (APEC) and Salmonella, cause severe infections in poultry products such as chickens and turkeys leading to food contamination and disease in humans. Previously, antibiotics were used to control bacterial infections and growth, contributing to more multi-drug resistant bacterial strains. The increased restrictions on the use of antibiotics in food-producing animals necessitate the development of new antibiotic alternative therapies. Here, the efficacy of novel antibacterial probiotics and peptides were tested against APEC and Salmonella infections in chickens. The alternative treatment methods disclosed herein are needed to combat these foodborne pathogens in avian animals and to help decrease the use of conventional antibiotics in poultry.

  • Patent number: 8227186
    Abstract: Clavibacter michiganensis subsp. michiganensis (Cmm) is an important Gram-positive-bacterial pathogen that infects tomato plants causing wilting and cankers and leading to severe economic losses in commercial tomato production worldwide. In order to visualize the infection process of Cmm in germinating seeds, bioluminescent Cmm strains were constructed by transforming the lux reporter gene into the bacterium. A vector pXX2 was constructed by inserting a modified promoterless lux-operon to a Cmm transposon mutagenesis vector, pKGT452C?. After electroporation, pXX2 carrying the Cmxr::luxABCDE::Tn1409 cassette resulted in insertion of lux-operon into the Cmm chromosome. The virulent, stable, constitutively bioluminescent strain BL-Cmm17 was selected for further characterization of growth properties and inoculation on tomato seeds. Using this bioluminescent strain, Cmm colonization dynamics of germinating seeds were monitored in real-time using the in vivo imaging system (IVIS).

  • Patent number: 8075879
    Abstract: Certain attenuated mutants of Brucella, especially B. melitensis, B. abortus, B. suis and B. ovis, when administered to a human or animal trigger a protective immune response such that subsequent challenge with virulent Brucella of the same species does not result in disease or results in much less severe symptoms. Functional inactivation of galE, a virB gene or the operon (ORFs 1087-1090) comprising the gene encoding ?-hexosaminidase (BMEI1087) and a lytic murein transglycosylase gene (BMEI1088). A specific example of the attenuated galE mutant which produces a protective immune response is B. melitensis GR024. The specific example of an inactivated ORF1087-1090 operon is B. melitensis GR026; it has an insertion mutation in the promoter region upstream of ORF 1090. Vaccination with live cells of either or both of these mutants results in a T cell response which protects the human or animal against challenge with virulent B. melitensis.
