Animais de importância médica de Mato Grosso do Sul

Abstract

Several species of animals (both invertebrates and vertebrates) produce chemical toxins that are used to kill or incapacitate prey or as a defense against potential predators. Some of these animals are capable of actively releasing their toxins into other animals through specialized teeth or by stinging them, and are therefore classified as venomous. They are distinguished from poisonous animals by the fact that the latter passively release their toxins into other animals through simple contact, or by inhalation, or even after being ingested. In Mato Grosso do Sul, we have records of several species of venomous animals that constitute a public health problem in the state and other regions of Brazil. Accidents caused by some of these species, especially those caused by arachnids, fish or snakes, can cause severe physical trauma and eventually lead to death. Considering that the identification of venomous species is an important procedure, as it allows the recognition of species of medical importance at a regional level and, at the same time, increases the population's awareness of the ecological importance of several of these species, this book was written by professors and students of the Institute of Biosciences of UFMS and aims to contribute to the training of students, professionals and future professionals in the areas of biological and health sciences, especially those interested in the study of hymenoptera, arachnids, fish, snakes and bats that occur in Mato Grosso do Sul.
