    ..coli may contribute to the CR against salmonella. We further conclude that, even at fecal levels below those reached during therapy, CI may impact the human gut flora sufficiently to facilitate colonization by S. kedougou...

    ..Based on our results, the no observed effect level (NOEL) of both tetracycline and erythromycin was 15 mg/60 kg person/d. The NOEL for neomycin was 1.5 mg/60 kg person/d...

  1. Mucin-degrading microflora for prophylactic antibiotics
    ROBERT CARMAN; Fiscal Year: 2007
    ..Our goal is to determine if the mucin-degrading flora restores or preserves normal mucin metabolism, enhances resistance to colonization by C. difficile, and reduces the incidence of C. difficile- induced antibiotic-associated diarrhea. ..
  2. C. difficile Toxin Membrane Test with Magnetic Particles
    ROBERT CARMAN; Fiscal Year: 2004
    ..perfringens enterotoxin, another cause of AAD. The technology developed in this project will be widely applicable for the development of new highly sensitive stool antigen tests. ..
