RESUMO
Amphibian chytridiomycosis, caused by infection with the non-hyphal, zoosporic chytrid fungus Batrachochytrium dendrobatidis (Bd), is an emerging infectious disease recognised as a cause of recent amphibian population declines and extinctions worldwide. The Doñana National Park (DNP) is located in southwestern Spain, a country with widespread Bd infection. This protected area has a great diversity of aquatic habitats that constitute important breeding habitats for 11 native amphibian species. We sampled 625 amphibians in December 2007 and February to March 2008, months that correspond to the early and intermediate breeding seasons for amphibians, respectively. We found 7 of 9 sampled species to be infected with Bd and found differences in prevalence between sampling periods. Although some amphibians tested had higher intensities of infection than others, all animals sampled were apparently healthy and, so far, there has been no evidence of either unusually high rates of mortality or amphibian population declines in the DNP.

Reference intervals of hematologic and biochemical blood profiles were obtained from 56 male and 58 female Mediterranean pond turtles (Mauremys leprosa) captured from the wild in different periods of their annual cycle. Mean (or median in nonnormal distributions) values of leukocyte differential were 53.8% and 58.5% heterophils, 35.3% and 32.6% eosinophils, 6.3% and 5.8% lymphocytes, 4.3% and 2% monocytes, and 0% and 0% basophils in males and females, respectively. Biochemical values did not differ from other chelonians, but values were generally higher in females than in males.

Pancreatitis associated with the helminth Serpinema microcephalus was found in three of 19 free-ranging red-eared slider turtles (Trachemys scripta elegans) captured between March 2003 and September 2004 in southern Spain. Microscopic changes were associated with parasite migrations and were characterized by central areas of necrosis surrounded by leukocytes and resulted in destruction of exocrine tissue. The blood profile of one of the three female turtles revealed eosinophilia and hyperglycemia, common in helminth infections and pancreatic disorders respectively. These are the first reported cases of pancreatitis caused by the nematode S. microcephalus in the exotic and newly colonized host T. s. elegans.

Falcaustra donanaensis sp. nov. (Nematoda, Kathlaniidae) from the large intestine of Mauremys leprosa (Testudines, Bataguridae) is described. By the absence of pseudosucker, arrangement of the male caudal papillae and the size of the spicules Falcaustra donanaensis sp. nov. resembles only to Falcaustra washingtonensis [Bursey and Aker (2001) J Parasitol 87:1082-1084], a species from Ambistoma tigrinum melanostictum in the Nearctic Region. Papillae pattern in the male of F. washingtonensis is similar to F. donanaensis, but differs by the presence of a median papilla in the American species, length of pharynx, spicule, and gubernacle in males, size of eggs, and number of eggs in female. This is the first species of Falcaustra reported in freshwater turtles in the Iberian Peninsula.
