“…4B). 32,48,60 A substituted β-cyclopropylamino acid toxin named diplonine was identified in S. maydis and found to cause nervous signs in guinea pigs, similar to those observed in ruminants. Diplodiosis is the most important mycotoxicosis of sheep and cattle in southern Africa 32 and has also been reported in cattle in Brazil 60 and Argentina 48 in corn stubbles during the autumn and winter (April-September).…”

Abstract. In the current study, mycotoxicoses of ruminants and horses are reviewed, with an emphasis on the occurrence of these diseases in South America. The main mycotoxicoses observed in grazing cattle include intoxications by indole-diterpenoid mycotoxins (Paspalum spp. contaminated by Claviceps paspali, Lolium perenne infected by Neotyphodium lolii, Cynodon dactylon infected by Claviceps cynodontis, and Poa huecu), gangrenous ergotism and dysthermic syndrome (hyperthermia) caused by Festuca arundinacea (syn. Festuca elatior) infected by Neotyphodium coenophialum (syn. Acremonium coenophialum), and photosensitization in pastures contaminated by toxigenic Pithomyces chartarum. Other mycotoxicoses in grazing cattle include slaframine toxicity in clover pastures infected by Rhizoctonia leguminicola and diplodiosis in cattle grazing in corn stubbles. The mycotoxicoses caused by contaminated concentrated food or byproducts in cattle include poisoning by toxins of Aspergillus clavatus, which contaminate barley or sugar beetroot by-products, gangrenous ergotism or dysthermic syndrome caused by wheat bran or wheat screenings contaminated with Claviceps purpurea, and acute respiratory distress caused by damaged sweet potatoes (Ipomoea batatas). The main mycotoxicosis of horses is leukoencephalomalacia caused by the fumonisins B1 and B2 produced by Fusarium spp. Poisoning by C. purpurea and F. elatior infected by N. coenophialum has also been reported as a cause of agalactia and neonatal mortality in mares. Slaframine toxicosis caused by the ingestion of alfalfa hay contaminated by R. leguminicola has also been reported in horses.

“…A critical analysis of the individual reports indicates, however, obvious gaps in many of the individual case descriptions, as often essential data, such as the amount of feed consumed per day, the animal's body weight, the time of exposure, the presence of other contaminants in the diet, and the animal health status, are not reported. This also applies to the reported outbreaks of acute mycotoxicoses such as Aspergillus clavatus toxicosis (Sabater-Vilar et al 2004), pithomycotoxicosis, which is only incidentally observed in Europe (Pinto et al 2005), and Diploida maydis toxicosis (Odrizola et al 2005). …”

The complex diet of ruminants, consisting of forages, concentrates, and preserved feeds, can be a source of very diverse mycotoxins that contaminate individual feed components. A number of mycotoxins are successfully inactivated by the rumen flora, whereas others pass unchanged or are converted into metabolites that retain biological activity. Hence, the barrier function of the rumen largely determines the susceptibility of dairy cows and other ruminant species towards individual mycotoxins. An impairment of this barrier function due to diseases or the direct antimicrobial effect of certain mycotoxins may increase absorption rates. The rate of absorption determines not only the internal dose and risk for adverse health effects, but also the excretion of mycotoxins and the biologically active metabolites into milk.

“…The lower results were noticed for cultivar C1 in potential P4, recording plants with 0.16 g of dry matter on average. It is known that S. maydis fungus is responsible for fi eld losses caused by decay of the stem, death of seeds / seedlings and can produce toxins harmful to human and animal consumption (Odriozola et al, 2005). By the results obtained in this study, it was also evident that the association of this pathogen with corn seeds can impair the quality of seeds and also the early development of seedlings from seeds infected by the fungus, with increasing and proportional effects to the values of potential of initial inoculum in seeds (Barrocas et al, 2012;Casa et al, 2006).…”

-The association of the fungus Stenocarpella maydis with corn seed may cause a reduction of seed germination and vigor of the emerged seedlings. This work was carried out in order to evaluate the effects of S. maydis on corn seed quality as well as on its early development. To evaluate such effects, seeds of cultivars RB9308YG (C1) and RB9108 (C2) were inoculated by the osmotic conditioner technique with two S. maydis isolates for 24(P1), 48(P2), 72(P3) and 96 hours (P4). Plants were grown in a room chamber at 20 °C and 25 °C and daily assessed until 28 days after emergence. Seed germination, incidence of S maydis, electrical conductivity, speed of emergence index (SEI), initial and final seedling population and dry weight of emerged plants, were assessed. The longer the exposition times of the seeds to the fungal colony, the more severe negative effects of the pathogens on seed vigor were observed. S. maydis caused reduced seed vigor in the speed of seedling emergence in the final stand and early development of corn seedlings.
