BACKGROUND Bracken fern (Pteridium aquilinum) has been consumed by humans and animals for centuries. However, its consumption is associated with a high incidence of cancer in the upper digestory tract of different species. Although the oral cavity is the first site of contact with ingested toxic

Details are given of the elimination of mitochondria which occurs during the first 1 to 2 hours of the life of the egg of the fern Pteridium aquilinum (L.) Kuhn. During this phase the only mitochondria present are swollen and appear degenerate, but subsequently the cytoplasm of the egg becomes

Early pathological changes of Bovine papilloma virus (BPV-2)-fern (Pteridium aquilinum and Onychium contiguum fern) interaction in hamsters were studied. In bracken-exposed cattle, BPV induces malignancy in gastrointestinal and urinary bladder mucosa. Cutaneous warts were transmitted successfully in

The consumption of bracken-fern (Pteridium aquilinum) as food is associated with a high incidence of cancer in humans and animals. Thus far, the carcinogenic effects of bracken-fern consumption could be related to chromosome aberrations verified in animal and in human peripheral lymphocytes. We

OBJECTIVE To assess the risk to human health of the plant bracken (Pteridium sp). METHODS An evaluation of studies of human and animal populations exposed to bracken, together with a review of expert reports and advice to the public. RESULTS Bracken induced disease has been demonstrated in animals

The ubiquitous bracken fern (genus Pteridium) is the only higher plant known to cause cancer naturally in animals. In addition to the well-recognized syndromes of thiamine deficiency, acute haemorrhage associated with myeloid aplasia and blindness due to retinal degeneration, it causes neoplasia of
