By: T.J. Smith The answer as to whether the botulinum neurotoxin (BoNT)-producing bacteria comprised six separate species required a complete revolution in microbial classification. Up to the turn of the last century, bacterial differentiations were based on morphological characteristic and biochemical activities, known collectively as phenotypic characteristics. However, the discovery of DNA as the ultimate […]
By: T.J. Smith Origins of Botulinum Toxin Types – relationships between toxins and the bacteria that produce them Soon after the discovery that botulism was caused by a toxin, multiple toxin types were identified. Initial characterizations were based mainly on serological differences, however other anomalies were noted, such as differences in toxicity, sensitivity or resistance […]
By: T.J. Smith Following a botulism outbreak due to contaminated ham that severely sickened 10 and resulted in the death of three people in Ellezelles, Belgium, a review and case study on botulism was published by a researcher named Emile Van Ermengem (Van Ermengem 1897). While Van Ermengem was not the first to study this […]
