Review of pathologic changes of the reptiles diagnosed at Department of veterinary pathology, Faculty of Veterinary medicine, University of Zagreb.

The objective of this retrospective study was to identify causes of mortality and common pathological changes in samples of reptiles analysed at the Department of Veterinary Pathology, Faculty of Veterinary Medicine, University of Zagreb in 2008-2018 period. Most of the necropsied reptiles (86%) were submitted from the Zagreb Zoo, while other sources accounted for 14% of the reptiles. 18% of biopsy samples was from Zagreb Zoo, and 82% from other sources. Off all of the necropsied carcasses, lizards were the most numerous group (40%), followed by snakes (31%) and tortoise (28%). A similar species distribution was in histopathological and cytological examinations, with stronger lizard domination and no snake cytological samples submitted. Research findings show that the most common causes of deaths were infections (septicemia, pneumonia, hepatitis, inclusion body disease), followed by metabolic disorders (uricosis, liver lipidosis, hypoproteinemia), combined lesions (egg peritonitis, cloacitis), and rarest traumas and tumors. In 15% of cases it was not possible to determine cause of mortality due to autolysis. The results of histopathological analysis coincide with the results of the necropsies. Among cytologic changes the most common were inflammatory and necrotic lesions. Overall results show that the causes of reptilian deaths do not differ significantly from the causes of deaths mentioned in the literature. Infectious and metabolic diseases prevail, while the proportions of traumas and parasitic invasions is lower compared to the references. The research has shown that some reptile infection have zoonotic potential. This highlights the need for performing pathological examinations in order to better control the diseases, improve quality of management and prevent the spread of zoonoses.
