AI Article Synopsis
- Cattle may be sensitive to botulinum toxin levels that current diagnostic techniques can't detect.
- Four lactating Holstein cows were dosed with varying amounts of Clostridium botulinum type C toxin, revealing that cows receiving 0.50 ng/kg showed clinical signs of botulism, while others did not.
- The study found that the median toxic dose for cattle is significantly lower than that for mice, indicating that cattle are much more sensitive to type C botulinum toxin.
Article Abstract
Because of the difficulty in identifying botulinum toxin in cattle, it is hypothesized that cattle are sensitive to levels of toxin below the detection limits of current diagnostic techniques (the mouse protection bioassay and the immunostick enzyme-linked immunosorbent assay [ELISA] for type C botulinum toxin). Using an up-down method for toxicologic testing, the median toxic dose (MTD50) for cattle was determined. Four lactating Holstein cows were dosed at 0.125 or 0.25 ng/kg with Clostridium botulinum type C toxin and failed to develop clinical signs of botulism during the 7-day observation period. Three cows given 0.50 ng/kg of toxin developed clinical signs of botulism. From these results, the MTD50 was calculated at 0.388 ng/kg (3.88 mouse lethal doses/kg) using the trim-logit method. These results suggest that cattle are 12.88 times more sensitive to type C botulinum toxin than a mouse on a per kilogram weight basis. The mouse protection bioassay and the immunostick ELISA for type C botulinum toxin failed to identify the presence of the toxin in the serum, blood, and milk samples taken from all 7 animals.

The literature in botulinum toxin treatment for painful diabetic neuropathy (PDN), post traumatic neuralgia (PTN), postherpetic neuralgia (PHN) and occipital neuralgia (ON) was reviewed up to Oct 1st 2024. Using the efficacy criteria set forth by the Assessment and Guideline subcommittee of the American Academy of Neurology, the current levels of efficacy for these conditions could be designated as followings: PDN: B (probably effective, two class II study), PTN: A (effective, two class I studies); PHN: A (effective, two class I studies), ON: (undetermined due to lack of blinded investigations). Due to the small number of patients in these studies, proof of efficacy requires conduction of controlled and blinded studies in large cohorts of patients with longer follow ups.

Introduction: To date, no investigations have been published regarding the concentration, dose, and technique for a mucosal spray application of botulinum toxin A (BTA) to alleviate hypersecretory symptoms of rhinitis in humans. It is a promising option for reducing common symptoms of seasonal allergic rhinitis (AR) and idiopathic non-AR. It is safer and less painful than intranasal injections, with high reported satisfaction in reducing clinical symptoms.

Recently, the Therapeutic Goods Administration (TGA) updated its guidance on cosmetic injectables advertising. The updates confirm that all direct or indirect advertising of cosmetic injectable products, including botulinum toxins or dermal fillers, is prohibited in Australia. While some commentators have lamented these updates, they present no changes to the law.
