ABSTRACT.
Cropland area in Uruguay, mostly soybeans, increased 300% during the last decade due to expansion to new areas. Although no-tillage practices are generalized among farmers, soil erosion is still a major environmental and economic issue. A predictive tool as the Water Erosion Prediction Model Project (WEPP), based on soil processes, has never been used in Uruguay. The objective of this research was to evaluate the soil erosion impact of various managements of intensive agriculture on Mollisols of Uruguay, applying the WEPP erosion model. The model was fi rst adjusted and validated for annual erosion estimates of an Abruptic Argiudoll (Nash Sutcliffe (NS)= 0.81 and R2 = 0.89) and a
Vertic Argiudoll (NS= 0.86 and R2 = 0.90), and later applied to evaluate three Mollisols and one Vertisol with different soil managements. Treatments combined no tillage (NT) and reduced tillage (RT) with different crop rotations. Crop rotations were: continuous soybean (CS), soybean-wheat (SW), soybean-winter cover crop (S-Cover crop), cornsoybean-wheat-3/4 yr pasture (CSW-PPP/PPPP), and corn-soybean-wheat-soybean-wheat-3/4 yr pasture (CSWSWPPP/PPPP). Soil erosion under RT system or CS was always above 7Mg.ha-1 (T value). Pastures inclusion under NT showed values below 7 Mg.ha-1.WEPP simulated an average erosion rate below T for SW rotation with NT (100m; 3% slope) in three of the four soils studied. However, by varying the slope and the length of the hillslope, the range for which the average annual erosion remains below this level is limited (only 3% - 4%). Moreover, for those hillslopes
whose average annual erosion does not exceed the T value, there is still approximately a 25% probability that this may occur any given year. Our work highlights the potential of using WEPP in the development of criteria for assessing sustainability of soil management, alternative to T value of average annual erosion units, including risk analysis MenosABSTRACT.

RESUMEN.- La rangeliosis canina es una enfermedad causada por el protozoario Rangelia vitalii y transmitida por garrapatas. Afecta caninos
domésticos y silvestres, provocando un cuadro de anemia hemolítica y trombocitopenia. En Uruguay ha sido reportada en los Departamentos de Artigas, Salto y Treinta y Tres. El presente trabajo describe un foco de rangeliosis canina en el litoral oeste del Uruguay, diagnosticado mediante estudios epidemiológicos, clínicos, hematológicos, anatomopatológicos y técnicas moleculares (PCR/secuenciación). El estudio se basó en 9 casos de perros raza Griffon Fauve de Bretagne provenientes de un predio rural próximo a Quebracho, Departamento de Paysandú. De los animales ocho murieron y uno respondió al tratamiento. Los principales signos clínicos fueron apatía, ictericia, fiebre, diarrea con sangre y sangrado por narinas y punta de orejas. Hematológicamente se constató anemia, trombocitopenia y leucocitosis. Los hallazgos macroscópicos se caracterizaron por palidez, ictericia generalizada, esplenomegalia, linfoadenomegalia y hepatomegalia. Al examen histopatológico se destacó: nefritis intersticial
con degeneración y necrosis tubular, miocarditis, necrosis hepática centrolobulillar. Congestión y edema pulmonar, linfoadenitis, y en bazo infiltrado inflamatorio difuso perivascular de tipo mononuclear. En diversos órganos se visualizaron zoítos de R. vitalii intracitoplasmáticas en las células endoteliales. En algunos animales así como en los caniles de los perros se constató presencia de Amblyomma aureolatum. De dos casos se extrajo
ADN de sangre y mediante PCR se amplificó un fragmento del gen 18s ARN ribosomal de Piroplasmas. La secuencia obtenida fue comparada con secuencias registradas en el GenBank utilizando la herramienta BLAST. El resultado reveló una homología entre 99-100% con R. vitalii. ---------------- SUMMARY.- Canine rangeliosis is a disease caused by the protozoan Rangelia vitalii and transmitted by ticks. It affects domestic and wild canines, causing hemolytic anemia and thrombocytopenia. In Uruguay it has been reported in the following counties: Artigas, Salto and Treinta y Tres. The present study describes a canine rangeliosis outbreak in the northwest littoral of Uruguay, diagnosed by epidemiological, clinical, hematological, anatomopathological and molecular techniques (PCR / sequencing). The study was based on 9 cases of dogs, Fawn Brittany Griffon breed, used for hunting; from a farm near Quebracho, Paysandú County. Eight animals died and one responded to the treatment. The main clinical signs were apathy, jaundice, fever, bloody diarrhea and bleeding from nostrils and tips of the ears. The hematological findings were anemia, thrombocytopenia and leukocytosis. Main macroscopic lesions were characterized by paleness, generalized jaundice, splenomegaly, lymphadenomegaly, and hepatomegaly. The principal histopathological lesions were interstitial nephritis with tubular degeneration and necrosis, myocarditis, centrolobulillar hepatic necrosis, edematous and congestive lung, lymphoadenitis and perivascular mononuclear inflammatory infiltration in spleen. In several organs were observed R. vitalii zoites inside the cytoplasm of endothelial cells. In some animals and as well as in dog kennels were present
Amblyomma aureolatum. DNA was extracted from blood of two cases and a fragment of the 18s ribosomal RNA gene of Piroplasm was amplified by PCR. The sequence obtained was compared to the sequences registered in the GenBank using the BLAST tool. The result showed a homology between 99-100% with R. vitalii.
