Resumen
BENCE, A.R. et al. Hallazgos clínico-patológicos compatibles con intoxicación con ionóforos en búfalas: primer reporte en Argentina. Rev. vet. [online]. 2018, vol.29, n.2, pp.79-82. ISSN 1669-6840. http://dx.doi.org/10.30972/vet.2923268.
A presumptive ionophore intoxication in a water buffalo dairy herd from Buenos Aires Province, Argentina, is presented. Buffaloes were grazing pastures and were supplemented with a pelleted ration formulated for dairy cattle, that included monensin in its composition. Five out of 50 lactating buffaloes showed tachypnea, dyspnea, sialorrhea, sternal decubitus and death. During post mortem examination hydrothorax, ascites, hemorrhagic centrilobular hepatitis, edematous thickening of the gallbladder, duodenum and diaphragm muscle and light-colored areas in the myocardium, were observed. Microscopically, moderate multifocal non-suppurative necrotizing myocarditis and myositis, severe centrilobular necrohemorrhagic hepatitis and severe pulmonary edema, were found. CPK and AST enzyme activities were significantly elevated in randomly samples buffaloes. Information from anamnesis together with clinicopathological findings are in concordance with natural and experimental ionophore poisoning. This is the first report of toxicity in water buffaloes in Argentina, a highly susceptible animal species to ionophores poisoning.
