Patient re -testing to monitor the antibody status during the course of treatment is recommended. All diagnostic test results should be considered within the context of clinical findings

Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium botulinum.C. botulinum elaborates eight antigenically distinguishable exotoxins (A, B, C 1, C 2, D, E, F and G).All serotypes interfere with neural transmission by blocking the release of acetylcholine, the principal neurotransmitter at the neuromuscular junction. The botulinum toxin does not cross the blood-brain barrier and affects only peripheral nerves. Human exposures are from types A, B, and E. Onset of symptoms depends on the amount of toxin ingested, absorbed in a wound, or inhaled. Pathogenesis following foodborne and inhalational toxin exposure is similar Worldwide, the most commonly used test is the mouse lethal dose 50 (LD50) assay. This assay involves injecting groups of mice with dilutions of the botulinum toxin to determine the dose that will kill half of the animals at a defined time-point. The test causes severe suffering as the toxin induces paralysis of the respiratory muscles Formation of . C. botulinum. toxin . When . C. botulinum. grows, it can produce a potent toxin, one of the most poisonous naturally occurring substances known Detecting botulinum toxin can be performed in a liquid such as serum obtained from blood. It can also be detected from the remains of food eaten that has caused a case or an outbreak of botulism. To perform the test using remains of food it is necessary to obtain an extract filtrate from it
