Fusarium species are common fungal pathogens of maize. Fusarium graminearum and Fusarium verticillioides, among others, can cause maize ear rot, and they are also mycotoxin producers. The aims of this work were to determine the frequency and diversity of Fusarium species in Uruguayan maize kernels, evaluate the toxigenic potential of the isolates, determine toxin contamination levels on freshly harvested grain, and assess the sensitivity of main Fusarium species against fungicides. Fusarium verticillioides was the most frequent species isolated, followed by Fusarium graminearum sensu stricto . Of F. verticillioides isolates studied for fumonisin production, 72% produced fumonisin B1 and 32% fumonisin B2. Considering in vitro toxin production by F. graminearum sensu stricto isolates, deoxynivalenol was the main toxin produced, followed by zearalenone and nivalenol. Fumonisins were the most frequently found toxins on freshly harvested maize samples (98% in 2018 and 86% in 2019), and also, fumonisin B1 was the toxin with highest concentration in both years studied (4860 µg/kg in 2018 and 1453 µg/kg in 2019). Deoxynivalenol and zearalenone were also found as contaminants. Metconazole and epoxiconazole were the most effective fungicides tested on F. verticillioides isolates. Fusarium graminearum sensu stricto isolates also were more sensitive to metconazole compared to other fungicides; nevertheless, epoxiconazole was less efficient in controlling this species. This is the first study that reports Fusarium species and mycotoxin contamination levels associated with maize grain in Uruguay. Its detection is the main step to develop management strategies in order to minimize fungal infection in maize crops. © 2023, The Author(s) under exclusive licence to Society for Mycotoxin (Research Gesellschaft für Mykotoxinforschung e.V.) and Springer-Verlag GmbH Germany, part of Springer Nature.

Se describe un brote de intoxicación espontánea por larvas del himenóptero Perreyia flavipes en un rodeo de bovinos Hereford en Flores, Uruguay. De un total de 187 bovinos expuestos de diferentes categorías enfermaron 43 y murieron 42, determinado tasas de morbilidad, mortalidad y letalidad de 22,9%, 22,5% y 97,7%, respectivamente. El curso clínico fue agudo, los signos incluyeron depresión, agresividad y babeo. El principal hallazgo patológico observado fue necrosis hepatocelular y hemorragia centrolobulillar aguda severa difusa. Además, se encontraron numerosos grupos de larvas de Perreyia sp. en el campo donde ocurrió el brote. Perreyia sp. causa hepatotoxicidad aguda con desenlace fatal en bovinos. Este brote recuerda que la intoxicación debe ser considerada entre los diagnósticos diferenciales de muerte con curso agudo en bovinos del país. .-.-.-.-.-.-.-.-. We describe an outbreak of spontaneous poisoning by larvae of Perreyia flavipes in a herd of Hereford cattle in Flores, Uruguay. Of a total of 187 exposed cattle of different categories, 43 developed clinical disease and 42 died, accounting for morbidity, mortality, and lethality risks of 22.9%, 22.5% and 97.7%, respectively. The clinical course was acute, signs included depression, aggressiveness, and drooling. The main pathological finding was severe acute diffuse centrilobular hepatocellular necrosis and hemorrhage. In addition, numerous groups of Perreyia sp. larvae were found in the field where the outbreak occurred. Perreyia sp. causes acute hepatotoxicity with fatal outcome in cattle. This outbreak highlights that this intoxication should be considered in the differential diagnoses of death with acute course in cattle in the country.
