|
The red-eared slider, Trachemys scripta elegans, is an exotic species spread all over the world. Together with competition with autochthonous turtles, the threat of introduction of potential pathogen agents and disease by these exotic turtles also needs to be considered. Thus, it is important to develop programs for monitoring and controlling the health of natural populations in areas including exotic turtles. A study of exotic and autochthonous turtles was made in two lakes in Huelva province (El Acebuche and El Portil), where naturalized populations of T. s. elegans had been previously detected. Blood profiles, microbiologic, parasitological and histopathological analyses were made to assess the health risk of this invasion. A high frequency of diverse pathologies was detected (hepatic lipidosis, pneumonia, pulmonary fibrous and interstitial nephritis), as well as a wide number of causal agents (Aeromonas, Pseudomonas, Pasteurella, Salmonella, micoplasmas y herpesvirus), showing that most exotic turtles from both localities were seriously ill, and the populations could be considered to be unhealthy, acting as a dispersal focus for pathogenic agents. We have not detected any transmission of pathogens from exotic to autochthonous species. However, this risk must be taken into account as long as exotic turtles are massively imported for the pet trade, and frequently released by their owners. Methods and results of this study will be of useful practical application in other wild populations, enabling a general evaluation of the health of autochthonous species.
