Abstract

Following intranasal inoculation, Vibrio cholerae KFV101 (DeltactxAB DeltahapA DeltahlyA DeltartxA) colonizes and stimulates tumor necrosis factor alpha and interleukin 1beta (IL-1beta) in mice, similar to what occurs with isogenic strain P4 (DeltactxAB), but is less virulent and stimulates reduced levels of IL-6, demonstrating a role for accessory toxins in pathogenesis. Morbidity is enhanced in C3H/HeJ mice, indicating that Toll-like receptor 4 is important for infection containment.
