| Sumario: | Diplodiosis, which is caused by Stenocarpella maydis, has emerged as a significant issue in Argentina, affecting cattle primarily in provinces like Buenos Aires, La Pampa, Santa Fe, and Córdoba. This work aims to document three outbreaks of cattle diplodiosis from 2015 to 2023 in the northwestern region of the country, highlighting clinical signs such as ataxia, muscle tremors, and paralysis, with affected animals often succumbing to the disease. Histopathological findings only revealed diffuse degeneration of cerebellar white matter, with no other significant lesions in other tissues. The disease is associated with toxic metabolites in contaminated maize, including diplodiatoxins and diplonine, although the exact pathogenic role of these toxins remains unclear. Epidemiological data showed varying incidence and mortality rates, and high lethality, with the appearance of the clinical signs after 10 to 15 days of exposure to the contaminated maize. These results highlight the need for further research into the toxicological mechanisms of S. maydis and its metabolites in cattle. |
