The role of bracken fern illudanes in bracken fern-induced toxicities
Mutation Research/Reviews in Mutation Research, 2019Bracken fern is carcinogenic when fed to domestic and laboratory animals inducing bladder and ileal tumours and is currently classified as a possible human carcinogen by IARC. The carcinogenic illudane, ptaquiloside (PTQ) was isolated from bracken fern and is widely assumed to be the major bracken carcinogen. However, several other structurally similar

AbstractBracken is a weed of economic importance to hill farming, conservation, and forestry in many parts of the world. It is an aggressive competitor, capable of rapid spread by means of its persistent underground rhizomatous system, and it is highly toxic and carcinogenic to domestic stock.

WHILE preparing a blood smear for the differential leucocyte count, it is found that the blood of cattle in the terminal stages of bracken poisoning does not spread evenly in the manner of a normal sample, but presents a blotched or streaky appearance1 (Fig. 1).

Reviews on Environmental Health, 1979
The study of bracken carcinogenicity affords an interesting example of the close alliance, with mutual benefit, between the work of veterinarians in the field and experimental research. On the one hand was the condition found in many parts of the world of bovine enzootic haematuria with uncertain aetiology and, on the other, the investigations ...

Carcinogenic Activity of Bracken
Nature, 1965THE bracken plant (Pteridium aquilinum) is known to contain radiomimetic activity. Ingestion by cattle of the whole plant, or of extracts, produces a syndrome in which there is panmyeloid bone-marrow damage, pyrexia, and often gut-lining damage and ulceration1; also typical are the widespread petechial haemorrhages2.

Reproduction of acute bracken poisoning in a calf with ptaquiloside, a bracken constituent
Veterinary Record, 1984Acute bracken fern toxicity in a calf was reproduced with ptaquiloside, a norsesquiterpene glucoside, isolated from the boiling water extract of bracken fern. Ptaquiloside was dissolved in 500 ml of saline and administered by drench at increasing dosages for six days out of every seven for the following periods: 400 mg/day for 24 days, 800 mg/day for ...
