Abstract     
Hematological and plasma biochemistry analyses were conduced on 51 Central American river turtles (Dermatemys mawii) during the dry (April-May) and rainy (September-October) seasons of 2006. Turtles came from two sites: Pantanos de Centla Biosphere Reserve and a turtle breeding farm, both located in Tabasco State, Mexico. Physical examination and body measures of animals were performed. Incidence and prevalence of hemoparasites were explored.Captive organisms (n = 29) were in poor physical condition and presented signs of illness while wild turtles (n = 22) were healthy. There were differences in several hematological parameters related with the condition and the season. During the dry season captive turtles exhibited higher levels of uric acid and urea, as well as lower levels of glucose. Haemogregarina sp. was detected in 100% of the wild individuals, but not in captives. Its incidence was greater during the rainy season. To the best of our knowledge, this is the first baseline health monitoring study of this critically endangered species.
