Abstract

In reptiles, several studies show the correlation between good or poor health and changes of physiologic parameters, but the comparison among data, methods and biochemical analysis in sea turtles are difficult. This study was carried out to investigate the biochemical patterns of total protein, albumin, creatinine, urea, alanine aminotransferase and aspartate aminotransferase (AST) in 100 loggerhead sea turtles (52 in good health, 16 with illness and 32 with serious illness). Blood samples were collected by venipuncture from the dorsal cervical sinus, the jugular vein or the ventral caudal sinus between March and October 2007 to 2009. Compared with subjects in good health, total protein and albumin concentrations were lower in subjects suffering from illness (p < 0.001) and in those with serious illness (p < 0.01). Compared with subjects with good health, creatinine concentrations (p < 0.001) and AST activity (p < 0.001) were lower in turtles with serious illness (p < 0.001), and urea concentrations were lower in subjects suffering from (p < 0.01). One-way repeated-measures analysis of variance showed significant effects of the health status of sea turtles on albumin (p < 0.05), urea (p < 0.001) and AST (p < 0.001) fluctuations. Data obtained showed a significant correlation between health status and haematochemical changes in sea turtles.
