  • Abomasitis associated with multiple antibiotic resistant salmonella enterica serotype typhimurium phagetype dt104
    Veterinary Microbiology, 2002
    Co-Authors: Steve A Carlson, W C Stoffregen, S R Bolin

    Abstract:

    Salmonella enterica serotype Typhimurium phagetype DT104 is a multiple antibiotic resistant pathogen that has been purported to be more pathogenic than other Salmonella. In this study, we evaluated the possibility that DT104 is the causative agent of veal calf Abomasitis observed in four independent outbreaks of salmonellosis. This study was undertaken to determine if the outbreaks might be due to hypervirulent S. enterica serotype Typhimurium phagetype DT104 (DT104) since Salmonella does not usually cause Abomasitis. Tissues and fluids from these calves were subjected to bacteriologic culture. Pure Salmonella cultures were then used in bovine challenge experiments. DT104 was identified as the causative agent of Abomasitis in calves. Thus, Abomasitis is a potential indicator of infection with multiple antibiotic resistant DT104 and adds credence to the apparent hypervirulence of this pathogen.

  • Secretion of a putative cytotoxin in multiple antibiotic resistant Salmonella enterica serotype Typhimurium phagetype DT104.
    Microbial Pathogenesis, 2001
    Co-Authors: Steve A Carlson, David K. Meyerholz, Thomas J. Stabel, Bradley D. Jones

    Abstract:

    Abstract Salmonella enterica serotype Typhimurium phagetype DT104 (DT104) is a multiple antibiotic-resistant pathogen. DT104 infections have been reported in a multitude of hosts including humans, companion animals, livestock and wildlife. Recently, several isolates of DT104 were recovered from veal calves exhibiting Abomasitis, a finding that is inconsistent with classic salmonellosis. One of these isolates was used in murine ligated loop experiments where it was observed that multiresistant DT104 can elaborate a putative cytotoxin. Thus it appears that DT104 has the ability to evade pharmacologic interventions, via antibiotic resistance, and elaborate a toxin that can damage cells.
