Fotossensibilização hepatógena em bovinos

Abstract

Photosensitization occurs worldwide and in all animal species, mainly in cattle and sheep. It can be subdivided into primary (with no liver damage) or secondary (hepatogenic). Hepatoxic plants are considered to be the most common cause of hepatogenic photosensitization in cattle. Phylloerytin, a product of degradation of chlorophyll, is most often associated with this disease.
