Paxilline is a toxic, tremorgenic diterpene indole polycyclic alkaloid molecule produced by Penicillium paxilli which was first characterized in 1975. [1] [2] Paxilline is one of a class of tremorigenic mycotoxins, is a potassium channel blocker, and is potentially genotoxic.

Upon consumption, the toxin inhibits ribosomal protein, DNA and RNA synthesis, [22] [21] [23] mitochondrial functions [24] [25] [26] cell division [27] [28] while simultaneously activating a cellular stress response named ribotoxic stress response. [29] The trichothecene mycotoxins can be absorbed though topical, oral, and inhalational routes. [21]
Nivalenol (NIV) is a mycotoxin of the trichothecene group. In nature it is mainly found in fungi of the Fusarium species. The Fusarium species belongs to the most prevalent mycotoxin producing fungi in the temperate regions of the northern hemisphere, therefore making them a considerable risk for the food crop production industry.
There were outbreaks of dog food containing aflatoxin in North America in late 2005 and early 2006, [38] and again in late 2011. [39] Mycotoxins in animal fodder, particularly silage, can decrease the performance of farm animals and potentially kill them. [40] [4] Several mycotoxins reduce milk yield when ingested by dairy cattle. [40]
Average annual premiums for pet insurance are approximately $676 for dogs and $383 for cats, while an exam and treatment at an emergency vet may cost several thousand dollars. How do claims affect ...
The number of pet dogs jumped as much as 16% between 2016 and 2020, while pet cats climbed as much as 6%, according to the American Veterinary Medical Association.
Biosynthesis pathway of fumitremorgin pathway involves several different enzymes. FtmA is a nonribosomal peptide synthase. Both FtmB and FtmH are prenyltransferase.Three different cytochrome P450 monooxygenases involved in the biosynthesis of furmitremorgin C are FtmC, FtmE, and FtmG.
