Histopathological changes in Lithobates catesbeianus tadpoles used as biomarkers of pesticide poisoning
The use of biological indicators has increased in recent years with the aim of investigating environmental pollution in aquatic environments that are vulnerable to the constant use of pesticides. Some biomarkers can help assess the health status, indicating physical, metabolic, and behavioral change...
PREVALIANE – NCIA VACTERIANA IN DOCE WATER Necrosis (Macrobrachium rosembergii, Decapoda, PALAEMONIDAE)

Nodules WITH DEPÓSIT OF CALCIO IN tadpoles AND imagos DE Rí TOURO (Rana catesbeiana SHAW, 1802)
Subcutive-nodules are reported in tadpoles and bull frogs, Rana Catesbeiana, in the State of São Paulo, Brazil. Initially, high tadpole mortality was observed in the early stages of metamorphose and then in young imags and frogs. The tadpoles had subcutive-nodular formations at the tail and lower p...
Hepatic response í to food supplementation in bull feathers subject to stress
The hepatoprotective effect of the food supplementation with probiotic (Bacillus subtillis) and betaglucana in bull frogs subjected to the condition of tenderness has been assessed. The animals were distributed in the treatments: T1: 100 animals m-2 (control), T2: 236 animals m-2, T3: 236 m-2 anima...
