In this study, our objectives were to understand the causes of diseases, including both infectious and noninfectious diseases, of the pet turtles in the middle of Taiwan. We collected 441 cases from 244 turtles representing eighteen species. A total of 441 clinical and necropsy cases of turtle recorded from October 2001 to April 2003, 18 species were studied in the experiment. Among theses cases, 244 cases with known pathogenic causes and 197 cases of none pathogenic causes. In the first category, the highest isolation is upper respiratory diseases. In the secondary category, the highest isolation is stress syndrown diseases. Most of 441 clinical cases were caused of nutritional imbalance, environmental changing, and stresses. The results showed the diseases of turtles caused with unsuitable of feeding by human. In 1999, the research workers at Endemic Species Research Institute captured 33 turtles, Ocadia sinensis and Trachemys scripta, from the Sun-Moon Lake. All turtles died with shell diseases. Another part of experiment, our objectives were to understand how many turtle with shell diseases in Taiwan and what kind of bacterium from shell lesions. We captured 136 turtles and examined 42 turtles. The incidence of shell lesions was highest in Trachemys scripta with 59 %. Ocadia sinensis had the next frequency of lesions with 41 %. The highest isolation bactera of lesions was Bacillus cereus. The secondary and third were Enterococcus spp. and Vibrio spp.. All of bacterium would make people to fall ill. It is an important problem to be care about the pathogens in the wild turtles.
