Scabies is an important skin disease in several species of domestic and wild animals; however, few reports in Brazil have emphasized its occurrence in buffaloes. This article describes the epidemiological, clinical and pathological aspects and diagnosis of psoroptic mange in buffaloes in a property in the municipality of Castanhal, PA, Amazon region. Of the 41 buffaloes examined, 38 males and females of the Murrah, Baio, Mediterranean and Carabao breeds and their crossbreeds, aged between 2 and 20 years, had a history of pruritus.

- - Meningitis is an inflammation of the membranes around the central nervous system, and its manifestation in water buffaloes has been inadequately documented; five cases of the condition were examined in adult Murrah and Mediterranean breed buffaloes from Castanhal, Brazil.
- - Clinical signs included neurological symptoms such as lethargy, difficulty moving, and convulsions; significant findings included loss of horn material, bloody discharge from the frontal sinus, and a notable increase in neutrophils in blood tests.
- - Necropsy revealed severe adherence of the dura mater, presence of purulent exudate on the brain and spinal cord, and cloudy cerebrospinal fluid, confirming a diagnosis of bacterial fibrinopurulent meningitis
This study aims to describe the clinical signs and ultrasonographic and necropsy findings of the first cases of proximal (Buffalo 1) and distal (Buffalo 2) vagal indigestion in two in the Brazilian Amazon biome. The clinical histories of the buffaloes were characterized by progressive weight loss, recurrent tympany, abdominal distention (apple and pear shapes), anorexia, and scant feces. Buffalo 1 was submitted to orogastric intubation, and due to the recurrent tympany, an exploratory laparotomy.
