Botulinum neurotoxin, produced by the bacterium Clostridium botulinum, causes botulism, a severe, rapidly progressing, and potentially fatal condition. Swift detection of the toxin and timely administration of antitoxin antibodies are critical for effective treatment. The current standard for Botulinum toxin testing is the mouse lethality assay, but this method is time-consuming and requires live animals.

The article is devoted to a form of botulism that has been little studied in our country and is registered exclusively in infants.

Taking into account the peculiarities of pathogenesis, the clinical manifestations of infant botulism have some features, which are discussed by the authors.

Objective: To evaluate the toxic effects of the agent Relatox on mature outbred rats and mice in an acute experiment in comparison with the registered analogue Dysport.
Material And Methods: Based on the aim of experiment, the acute toxic effects of Relatox and Dysport were assessed on two animal species: rats and mice at intraperitoneal and intramuscular administration at dose levels that made it possible to calculate the toxicological parameter values (initially 10-150 U/kg with subsequent usage of additional doses 20 U/kg to 300 U/kg depending on the agent and route of administration). The LD values and other acute toxic parameters were calculated using probit analysis.
