Summary: | Abstract. The study of spontaneous neoplasms in fish is supported, among other reasons, in the possibility of relating them to the water pollution; the fish in this case used as indicators of the presence of environmental carcinogens. The mechanisms of mutagenesis and carcinogenesis in fish are interconnected and influenced by environmental chemical or physical agents, or associated with infectious agents, especially retrovirus. In this regard, a summary of the findings of swim bladder leiomyosarcomas in association with retroviruses in Atlantic salmon from North America is presented.Resumo. O estudo das neoplasias espontâneas em peixes é apoiada, entre outras razões, na possibilidade de relacioná-las à poluição aquática; os peixes, neste caso, utilizados como bioindicadores da presença de carcinógenos ambientais. Os mecanismos de mutagênese e carcinogênese em peixes estão interligados e influenciados por agentes físicos ou químicos ambientais, ou, ainda, associados a agentes infecciosos, em especial os retrovírus. A este respeito, é apresentado um resumo dos achados sobre leiomiossarcomas de bexiga natatória em associação com retrovírus no salmão do Atlântico da América do Norte |
