Pathologic findings in hatchling and posthatchling leatherback sea turtles (Dermochelys coriacea) from Florida

In an attempt to identify critical health issues affecting the survival of endangered leatherback sea turtles (Dermochelys coriacea), a prospective study was conducted in several dead-in-nest hatchlings and captive posthatchlings to examine pathologic changes and presence of pathogenic microorganisms. Numerous histopathologic changes were identified. Although bacterial etiologies were suspected in deaths of captive individuals, a single causative organism was not identified but rather, a mixed population of bacterial flora was cultured. Muscle degeneration observed in most samples implicates a potential environmental factor in species survival and needs future investigation.
