Surtos de botulismo em bovinos no Brasil associados à ingestão de água contaminada

Botulismo em bovinos resulta da ingestão de toxina previamente formada. No presente trabalho são descritos sete surtos da intoxicação onde os dados clínico-patológicos, epidemiológicos e os achados laboratoriais indicaram a possível ingestão da toxina através da água contaminada. O coeficiente médio de mortalidade foi de 20,1%, com letalidade de 99,92%, e morbidade de 31,62%. Dos cerca de 9.000 bovinos envolvidos nos surtos, 2.844 morreram com quadro clínico predominantemente superagudo e agudo. A alta morbidade e mortalidade foram registradas num curto período de tempo e envolveram todas as categorias animais, com quadro clínico-patológico caracterizado por paresia e paralisia da musculatura da locomoção, deglutição e mastigação e ausência de lesões macroscópicas. As circunstâncias em que ocorreram os surtos estiveram relacionadas com a existência de carcaças de animais decompostas ou matéria orgânica vegetal na água de dessedentação. Foram detectadas toxinas botulínicas C e/ou D nas coleções de água, nas vísceras e no soro sangüíneo de parte considerável dos materiais examinados.

Caso alóctone de leishmaniose visceral canina, no município de Campo Mourão, Paraná, Brasil

This report aims to describe the first case allochthonous of visceral leishmanisasis (VL) in the municipality of Campo Mourao, Parana, Brazil, in a canine, Boxer breed, with eye and skin lesions, lymphadenomegaly and splenomegaly, attended at Veterinary Hospital at the Faculdade Integrado de Campo Mourao, after residing in the city of Campo Grande, Mato Grosso do Sul. The diagnosis of the disease was based on direct observation of amastigotes of Leishmania spp., in popliteal lymph nodes, suggesting that a case of VL, since the animal came from an endemic area for the disease. The migration of infected dogs from endemic regions to areas unaffected becomes a problem for public health, since it may allow the installation of new outbreaks by encouraging the spread of disease throughout the country.

Novos Registros sobre Meloidogyne mayaguensis no Brasil e Estudo Morfológico Comparativo com M. incognita

Almeida, E.J., P.L.M. Soares, A.R. Silva & J.M. Santos. 2008. New records on Meloidogyne mayaguensis in Brazil and comparative study with M. incognita. Meloidogyne mayaguensis is the plant-parasitic nematode responsible for a great impact on guava production in Brazil, since it has been the cause for eradication of thousand of hectares of guava plantations in the Northeastern region. In the present study, this species was detected in soybean fields of Ituverava municipality, São Paulo state, and in different vegetable crops (lettuce, cucumber, pepper and cherry tomato) in Chapada dos Guimaraes municipality, Mato Grosso state, causing root galls and other symptoms. The species was identified on the basis of the perineal pattern of females, and on the morphology and morphometry of anterior region of males. Isozyme phenotype for esterase was used for confirmation. This constitutes the first report on the occurrence of M. mayaguensis on lettuce, cucumber, pepper and cherry tomato cultures in Mato Grosso state and the first one in soybean in São Paulo state. It was found that morphological features of male anterior region and female perineal pattern are enough for the safe distinction between M. mayaguensis and M. incognita.

Specimens collected on trips were identified at laboratory of Fca/Unesp/Botucatu-SP. It were recorded, for the first time, the occurrence of A. rugosus rugosus (F. Smith, 1858) in Paraná, Rondônia and Santa Catarina states; A. subterraneus subterraneus (Forel, 1893) in Amapá and Bahia; A. diasi Gonçalves, 1982 in Rio Grande do Sul and Paraná states; A. coronatus (Fabricius, 1804) in Paraná; A. balzani (Emery, 1890) in Amapá and A. subterranens brunneus (Forel, 1911) in Goiás.

Primeiro registro documentado de Alectrurus tricolor para o Pantanal, Brasil

The Cock-tailed Tyrant (Alectrurus tricolor, Vielliot 1816) is reported here for the first time in the Brazilian Pantanal. The species was seen twice (August and September 2005) in the northern portion of Fazenda Rio Negro, in the region of Nhecolândia. Sexual displays were observed, suggesting that reproduction is occuring in this area.

Cursos de geologia: expansão, interiorização e consolidação do ensino de geologia no brasil

A short time after the creation of the first Geology courses in Brazil (in 1957 with the pioneers in the University of São Paulo and in the Federal Universities of Ouro Preto, Pernambuco and Rio Grande do Sul, and then in the following year in the Federal Universities of Bahia and Rio de Janeiro), there arose other initiatives that spread almost twenty Geology courses throughout Brazil. In addition to expanding the Geology teaching in the South, Southeast and Northeast regions, these initiatives succeeded in allowing access to geological education for the population in the North and Central-west of Brazil. In the 1960s, the courses in the Federal University of Para in Belém (1964), University of Brasilia (1965) and São Paulo State University in Rio Claro (1969) were implanted. In the following decade, the courses in the Federal Rural University of Rio de Janeiro in Seropédica (1970), the Federal University of Ceará in Fortaleza (1970), the University of Rio dos Sinos in São Leopoldo (1973), the Federal University of Paraná in Curitiba (1973), the Federal University of Minas Gerais in Belo Horizonte (1973), the Federal University of Amazonas in Manaus (1976), the Federal University of Mato Grosso in Cuiabá (1976), the Federal University of Rio Grande do Norte in Natal (1976), and the State University of Rio de Janeiro in Rio de Janeiro (1977) were all created. At the close of the twentieth century, the course was implanted in the State University of Campinas (1998). Now, at the beginning of the twenty-first century, new Geology courses are being implanted, accentuating the movement inland of Geology teaching in Brazil. The Federal University of Pará began a new course in its campus in Marabá in the south-east of Pará and the Federal University of Bahia implanted a new course in its campus in Barreiras in the west of Bahia. Finally, the Federal Universities of Sergipe, Espírito Santo and Roraima commenced Geology courses in Aracaju, Alegre and Boa Vista, respectively. This chapter will present the synthesis of the Geology courses which, over the last decades of the twentieth century, contributed to the expansion of Geology teaching in the country, taking it to every region and giving opportunities to a large number of Brazilian citizens to realize their dreams and tread the paths of their professional vocation.

Estudio de la compactación de un Ferralsol manejado con un sistema de no laboreo en Selvíria (MS, Brasil)

No tillage management is widely used by the Brazilian farmers and technicians like a soil conservation system, which reduces the soil losses by water erosion, increasing the infiltrated and stored water in soil, warranting environmental sustainability. No-tillage system does not invert the soil; it causes the creation of a compacted layer. The samples were taken in the agricultural year 2005/2006 in an Oxisoil at Selviria (MS/Brazil). The tillage management in the last 15 years was no-tillage system with crop rotation (maize -Zea mays L./bean - Phaseolus vulgaris L.). The analyzed soil physical properties were bulk density (BS), gravimetric water content (U) and mechanical resistance to penetration (RP) at three depths: 0-0.10 m, 0.10-0.20 m and 0.20-0.30 m. The samples were taken in a mesh with 117 sampled points covering an area of 0.16 ha. It was investigated the existence of compacted soil layer, using the mechanical resistance to penetration to 0.60 m depth with soil water content at field capacity. The data shows low coefficient of variation, except the resistance penetration data. Bulk density and gravimetric water content has a normal distribution. Only resistance to penetration at 0.10-0.20 m depth layer has a normal distribution. The correlation between different properties was low. The bulk density increases with depth; the increase of the values of soil bulk density are consistent with data in other papers, indicating there are not compaction problems for the crop development at the study area. Most of the values of resistance to penetration are lower than 2 MPa, being this value restrictive for root development. The analysis of resistance to penetration profile 0 to 0.60 m shows a compacted layer between 0.20-0.30 m. This compacted layer was caused by the conventional tillage system used at this area before the use of no-tillage system. The soil bulk density has higher values at the upper area, that it shows higher values of soil compaction. Although the values of bulk density and resistance to penetration are high, the area does not show great problems of soil compaction.

Os elementos do espaço turístico da fronteira Brasil-bolívia

The geographical space aimed by this study was the Brazil-Bolivia border, involving the urban areas of the Brazilian city, Corumbá, and the Bolivian ones, Puerto Quijarro and Puerto Suárez. The objective of this study was to analyze the touristic border spaces, speculating about their similarities and divergences regarding integrated planning. Secondary data, resulting from field work, was used in the methodology. The border generates a tangled web of relationships and streams. The presented spatial elements mix complex rationalities, sometimes approaching, sometimes denying and even disregarding the possibilities that can be translated by the border.
