In the past few decades there has been a growing number of therapeutic applications for Botox which include treatment for migraines, leaky bladders, excessive sweating, and cardiac condition.Considering the growing need Canadian and American scientists have discovered a New type of Botox from a new source which is a strain of animal gut bacteria known as Enterococcus faecium.
“This is the first time that an active botulinum toxin has been identified outside of Clostridium botulinum and its relatives, which are often found in soil and untreated water,” said Andrew Doxey, one of the study’s two corresponding authors and a bioinformatics professor at the University of Waterloo. “Its discovery has implications in several fields, from monitoring the emergence of new pathogens to the development of new protein therapeutics–it’s a game changer.”
Doxey’s findings were developed in collaboration with researchers from Harvard University and the Boston Children’s Hospital.
In the study, originally designed to investigate the origins of antibiotic resistance in E. faecium bacteria, the researchers were able to sequence the genome of the E. faecium bacteria drawn from cow feces. The genome was then run through computer programs in Doxey’s lab, which found the gene for botulinum toxin in the bacterial strain.
The researchers concluded that the botulinum toxin was likely transferred from C. botulinum bacteria in the environment into the E. faecium bacteria in the cow’s gut, showing that the toxin can be transferred between very different species.
“The botulinum toxin is a powerful and versatile protein therapeutic” says Michael Mansfield, a Biology doctoral candidate in the Doxey Lab and one of the study’s lead authors. “By finding more versions of the toxin in nature, we can potentially expand and optimize its therapeutic applications even further.”
