Janthitrem A is a mycotoxin that has been found inP. janthinellum.1It induces tremors in mice and decreases the time to fall from the rotarod when administered at a dose of 4 mg kg.2Janthitrem A (20 μg g) also reducesW. cervinatalarvae weight gain and food consumption. 1.Gallagher, R.T., Latch, G.C., and Keogh, R.G.The janthitrems: Fluorescent tremorgenic toxins produced by Penicillium janthinellum isolates from ryegrass pasturesAppl.
