Pathology affecting Crocodylus acutus (Cuvier, 1807) in the Sabanalamar hatchery, Cuba

Resumen

The management and poor feeding during breeding American crocodile Crocodylus acutus (Cuvier, 1807) are stressors that predispose to disease. In the breeding of C. acutus Sabanalamar, province of Pinar del Rio, Cuba, the weakening of the physical conditions and the onset of disease mortality occurred in juveniles of this species. That determine the need for first in Cuba a diagnosis of pathologies affecting this category low housing systems. Studied 10 juvenile C. acutus by bacteriological and histopathological examinations. Bacterial pathogens isolated in highest percent belong to the genera Aeromonas and Pseudomonas. Aeromonas was sensitive to antibiotics and gentamicin amikacin, whereas Pseudomonas present in all organ samples was resistant to 10 antibiotics tested. The pathological changes observed allowed diagnose malnutrition with vitaminosis process that led to a weakening of the animals and the emergence of bacterial septicemia cause mortality in juvenile American crocodile Sabanalamar Hatchery.
