- Abstract
Herein we describe septicemic outbreaks affecting pre-metamorphic bullfrog tadpoles (Rana [Lithobates] catesbeiana Shaw, 1802). The survey was performed in three commercial frog farms located in Goiás State. Clinical assessment and tadpole sampling for necropsy, histopathology, microbiology, parasitology, transmission electronic microscopy and molecular studies were performed. Septicemic outbreaks were characterized by edema, ascites and nervous signs. Main etiological agents identified were Gram-positive cocci. Lesions were more prevalent in liver and kidney, but they were also found in other internal organs. Typical lesions were degeneration and necroses associated to mononuclear lympohcytes and granuloma formation. The disease may be considered as a "secondary streptococcal septicemia". It was not possible to determine the primary cause preceding tissue colonization by streptococci, but the intensive husbandry practices might have an important role.
