RESUMEN.- La pitiosis es una enfermedad ampliamente distribuida a nivel mundial causada por Pythium insidiosum. Esta es transmitida y
propagada en ambientes semiacuáticos afectando principalmente a equinos, caninos, felinos, bovinos y el hombre. En el departamento de Paysandú, Uruguay, en el mes de mayo 2017 se registró un caso de pitiosis en un equino hembra raza Criolla de 24 años. Se realizó la extirpación quirúrgica de una extensa lesión circular ubicada en zona abdominal. Macroscópicamente se observó tejido de granulación, áreas multifocales de necrosis con contenido supurativo hemorrágico, concreciones del tipo pastoso a gredoso de color blanco amarillento. Al examen histopatológico por medio de la tinción de H&E se destacaba ulceración difusa de la epidermis; con severa proliferación de tejido de granulación, abundante tejido conjuntivo, neovascularización, áreas multifocales de necrosis eosinofílica rodeada por abundantes polimorfonucleares, principalmente eosinófilos, y macrófagos en dermis superficial y profunda. Dentro de las áreas de necrosis se observó la presencia de hifas coloreadas positivamente con la coloración argéntica de Grocott. Se obtuvo inmunomarcación positiva para P. insidiosum. En el cultivo del material se aislaron colonias de color blanquecino y crecimiento radial con desarrollo de micelios aéreos luego de 48 horas. Se confirmó el aislamiento de P. insidiosum mediante la
inducción de zooesporas y la caracterización de las mismas. Por medio de la reacción de PCR-anidado se amplificó la región ITS (ITS1, 5.8S, ITS2) y en una segunda reacción se amplió el gen específico para P. insidiosum de la región ITS1. La secuencia obtenida fue comparada con la registrada en el GenBank confirmando una homología de 100 % con P. insidiosum. ---------------- SUMMARY.- Pythiosis is a disease widely distributed worldwide caused by Pythium insidiosum. It is transmitted and propagated in semi-aquatic environments, mainly affecting equines, canines,
felines, cattle and humans. In Paysandú County, Uruguay, in the month of May 2017, a case of pitiosis was registered in a 24-year-old Creole breed female equine. An extensive circular lesion located in the ventral abdominal area was surgically removed. Macroscopically, it was observed granulation tissue, multifocal areas of necrosis with suppurative hemorrhagic content and yellowish-white pasty to chalky concretions. At the histopathological examination with H&E stain there was of notice diffuse ulceration of the epidermis; in superficial and deep dermisthere were severe proliferation of connective tissue, neovascularization, multifocal areas of necrosis surrounded by infiltration of polymorphonuclears, mainly eosinophils, and macrophages. Inside of the areas of necrosis there was presence of hyphae stained positively by the argentic Grocott stain.
Positive immunostaining was obtained for P. insidiosum. In the culture of the fresh material, colonies of whitish color and radial growth were isolated with the development of aerial mycelia after 48 hours. The isolation of P. insidiosum was confirmed by the induction of zoospores and the characterization of them. The ITS region (ITS1, 5.8S, ITS2) was amplified by the nested PCR reaction and in a second reaction the gene specific for P. insidiosum from the ITS1 region was amplified. The sequence obtained was compared with that registered in GenBank confirming a 100% homology with P. insidiosum.

Abstract:
Technological (processing performance and end-product) and nutritional quality of wheat is in principle determined by a number of compounds within the wheat grain, including proteins, polysaccharides, lipids, minerals, heavy metals, vitamins and phytochemicals, effecting these characters. The genotype and environment is of similar importance for the determination of the content and composition of these compounds. Furthermore, the interaction between genotypes and the cultivation environment may play a significant role. Many studies have evaluated whether the genotype or the environment plays the major role in determining the content of the mentioned compounds. An overall conclusion of these studies is that except for compounds encoded by single major genes, importance of certain factors mainly depend on how wide environments and how diverse cultivars are within these comparative studies. Comparing environments all over, e.g. across Latin America, ends up with a high significance of the environment while large studies including genotypes of wide genetic background result in a significant role for the genotype. In addition, for some technological properties and components, genotype has a higher effect (e.g. grain hardness and gluten proteins), while environment influences stronger on others (e.g. protein and mineral content).Content and concentration of proteins, but also to some extent of starch, some non-starch polysaccharides and lipids, are essential in determining the technological quality of a wheat flour. For nutritional quality of the flour, the majority of the compounds are together the important determinant. Thus an increased understanding of environmental effects is essential. As to how the environment is influencing the content of the compounds, there are some differences. The protein content and composition is strongly affected by environmental factors influencing nitrogen availability and cultivar development time. However, these two factors are impacted by a range of environmental (temperature, precipitation, humidity/sun hours, etc.) and agronomic (soil properties, crop management practices such as seeding density, nitrogen fertilizer application timing and amount, etc.) components. Thus, to understand the interplay between the various environmental and agronomic factors impacting the technological quality of a wheat flour, modeling is a useful tool. Several other compounds, including minerals and heavy metals, are to a higher extent determined by site specific variation, resulting in similar rankings of entries across locations, although the total content is varying among years. The bioactive compounds and vitamins are a part of the defense mechanisms of plants and thus there is a variation in these compounds depending on prevailing biotic and abiotic stresses (heat, drought, excess rainfall, nutrition, diseases and pests). Thus, even for nutritional quality of wheat, incorporating all compounds of relevance in the evaluation would benefit from modeling tools. MenosAbstract:
