Ecotoxicological Studies as a Tool on Amphibians’ Disease Risk Assessment

Amphibian natural populations are strongly affected by pathogenic agents. The risk of disease is dependent on the pathogen environmental conditions, capacity of infection and the host’s susceptibility to disease. Changing the environment, in which amphibians thrive, modifies the distribution, increases the risk for diseases transmission and even affects the ecology of populations. Therefore, chemical contamination can act as stressor both for host and/or pathogens and can change the host-pathogen’s dynamics. Saprolegnia spp. has been responsible for large economic losses in aquaculture industry. Furthermore, it frequently causes infections and population losses in amphibians. Leer más.
