title: Rapid in vivo assay method for type G botulinal toxin.
abstract: The survival time (ST) dose-response curve for Clostridium botulinum type G toxin was determined in mice and evaluated as a rapid assay method. As it occurs with other botulinal toxin types, the results showed a linear relationship between the logarithm of the injected dose and the logarithm of ST. The slope of the ST dose-response curve for type G toxin differed significantly from those for type A or subtype Af toxins. This parameter was altered when trypsin-activated type G toxin was used. The ST dose-response curve was rather stable. This in vivo assay method could be applied for the estimation of the potency of G toxin preparations in a short time using only some few mice.
