摘要

Following intranasal inoculation, Vibrio cholerae KFV101 (ΔctxAB ΔhapA ΔhlyA ΔrtxA) colonizes and stimulates tumor necrosis factor alpha and interleukin 1β (IL-1β) in mice, similar to what occurs with isogenic strain P4 (ΔctxAB), 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.
