Article Synopsis
- - 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
Melanomas are tumors arising from externally uncontrolled melanocytes that produce varying amounts of melanin. In this study, we report a case of melanoma with neurological impairment without evidence of cutaneous neoplastic lesions in an adult buffalo in the state of Pará, Brazil. Clinically, the buffalo exhibited apathy, decreased mandibular tone, and occasionally an open mouth with motor incoordination, and eventually succumbed to the condition.

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.

During autopsy, yellowing of the leptomeninges at the ventral pons to medulla oblongata was noted. In the cerebellar peduncles, there was a focally extensive black-to-yellow area at the level of the vestibular nuclei.

- * Out of 153 equine cases studied, 52 were affected with 19 fatalities, showing clinical signs mainly of colic and abdominal issues, typically developing within 12 hours to 4 days.
- * Despite normal serum levels of key enzymes, there were elevated urea nitrogen and creatinine, alongside severe digestive system lesions, including hemorrhages and ulcerations; the precise toxins responsible for this condition remain unidentified.
