Leucoencefalomalácia em equídeos da região Leste de Mato Grosso

Background: Fumonisins produced by Fusarium verticillioides are among the most important medical mycotoxins known. The intake of concentrate based on corn and corn by-products contaminated with fumonisins can cause severe poisoning in horses. The injuries are observed mainly in the white matter of the brain, and the disease is known as Equine Leukoencephalomalacia (ELEM). This study aims to describe and discuss the epidemiological, clinical and diagnostic aspects of an outbreak of ELEM occurred in three farms in the municipalities of Canarana and Agua Boa, in the eastern region of Mato Grosso, Brazil.Materials, Methods & Results: The outbreak occurred between May and August 2010. The disease affected six horses and four mules of different ages and sex. Clinical examination was only possible in animals with chronic evolution of the disease. All the affected animals showed neurological clinical signs such as ataxia and recumbency, which progressed to death or sudden death. Histopathological analysis showed foci of necrosis that predominantly affected the white matter, and the presence of gitter cells. Degenerative lesions were observed in the liver of the animals. Mortality rate ranged from 12.5 to 71%, and lethality reached 100%. The cases were preceded by sudden drops in the weather temperature. Fumonisins levels of 6.6 ppm were detected in the feed of the animals.Discussion: The presumptive diagnosis of leukoencephalomalacia was consistent and based on clinical and epidemiological studies. However, the definitive diagnosis was based upon the histological features of the brain including the presence of extensive areas of malacia. Moreover, the animals were being fed with corn or corn by-products contaminated with fumonisins levels considered to be toxic to equids. The mortality and lethality rates are in agreement with outbreaks described in previous studies. The animals showed neurological signs as the predominant clinical manifestation, with gait ataxia followed by recumbency, prostration and death between 24 h and 29 days. Similarly to other reports, the disease was more frequent in adult animals, which succumbed in 24-48 h. Conversely, the evolution of the disease in young animals was of 10 to 29 days. Sudden death was more prevalent in the mules. Previous studies have shown a predominance of cerebral and brainstem lesions in horses, whereas in mules the clinical signs are related to brainstem lesions. Corn and corn by-products are commonly used as energy supplementation to horses in the southern of Mato Grosso state, but outbreaks of the disease are uncommon. This may be influenced by the prevalence of hot climate conditions, which does not favor the production of toxin by the fungus. The atypical low weather temperatures (9-11 degrees C) observed prior to the outbreak could have contributed to the mycotoxin production by F. verticillioides, which requires temperatures between 8-12 degrees C to produce toxins. However, the disease in the region may be underestimated, considering that the practice of necropsies is not common among field technicians, mainly in the occurrence of sporadic deaths among horses intended for work. Preventive measures include avoiding the use of corn and corn by-products for horses after periods of sudden drops in temperature in the region. Furthermore, clinical and epidemiological surveys and post-mortem and histopathological analyses are undoubtedly important for appropriate differential diagnosis, especially in equids with neurological signs.

Formação do professor para trabalhar com recursos de tecnologia assistiva: um estudo de caso em Mato Grosso

Due to the process of educational inclusion, it is necessary for the teacher who works with disabled students to acknowledge and master the resources of assistive technology equipment available in Brazil. The objective was to identify the presence of these resources at school and evaluate, having the teacher as the evaluator, the conditions of dealing with the Assistive Technology resources and equipment. The sample consisted of 14 teachers who work in the Resources Multifunction Classroom and 18 regular classroom teachers who have disabled students enrolled in their classrooms. Data collection was performed through the TAE Questionnaire - Assistive Technology for Education. The data collection was performance in groups during the training course sponsored by the Education Department of Rondonópolis as part of the Program of Continuing Education Training for Managers and Educators - Inclusive Education: The Right to Diversity. The questionnaire data indicated differences between the two groups mentioned. The teachers of the Resource Classes indicated that Assistive Technology resources are now being introducing at schools and that over 50% of this group understand the resources presented on the questionnaire. Most of the regular classroom teachers is still unaware of the Assistive Technology resources and equipment. Regarding the dealing of these resources the group of teachers from the multifunctional classroom is better prepared to use this technology. The data suggest the need for investment in acquisition and training of teachers in relation to Assistive Technology resources.

Influência do uso e ocupação da terra na dinâmica do rio São Lourenço - estado de Mato Grosso

This study aims to analyze the relationship between deforestation in the highlands of the São Francisco River Basin over the past 45 years due to agricultural activities and livestock , and the observed changes in the dynamics of the same river in the Pantanal of Mato Grosso , as sinuosity , discharge sediment , flow, points of erosion and morphological changes . It is observed that deforestation occurs in the plain and on the plateau , however with much more intensity in the latter, provided the extensive land use in the region . Thus, the study aims to contribute to a better understanding of the relationships between the uplands and flood plains . To achieve this goal will be used proper methods of geomorphological and geological sciences , with emphasis on the use of satellite imagery and hydrological data side . The research will include the following steps : I) literature review ; II) characterization geomorphological , geological , hydrological and climate , III) Dynamics of vegetation ; IV) Analysis of cause-effect relationships in the river system . Product analysis will suggest preventive measures to minimize the effects caused by the practices of use and occupation in the study area, as well as other regions suffer the same impacts

The helminth fauna of twenty-five Hypsiboas raniceps (Anura, Hylidae) specimens collected in the pantanal wetland, municipality of Corumbá, Mato Grosso do Sul State, Brazil was studied. Twenty (80%) specimens were parasitized with at least one helminth species. The helminth fauda is composed by the nematodes Oswaldocruzia mazzai, Cosmocerca podicipinus and Physalopteroides venancioi beyond the no identified species of the genus Rhabdias, Physaloptera and Raillietnema and the family Cosmocercidae. Cysts and larvae of nematodes were also found. Catadiscus propinquus and diplostomid metacercariae were the recovered trematodes

Movimentação de indivíduos de uma população de antas (Tapirus terrestris) em uma paisagem fragmentada no cerrado do Mato Grosso do Sul

A anta é um megamamífero vulnerável à extinção (IUCN), apresenta baixa taxa reprodutiva e é uma espécie de elevada importância na manutenção da estrutura das florestas, este estudo pretende avaliar a movimentação de indivíduos de anta em uma paisagem antropizada no cerrado do Mato Grosso do Sul. Dada a dificuldade de estudos com técnicas tradicionais de campo, estão sendo realizadas análises moleculares de amostras não-invasivas (fezes) com marcadores microssatélites, a fim de estimar o número de indivíduos que utilizam essa área, além de gerar informações genéticas que podem ser úteis para auxiliar programas de conservação para esta espécie. Para tal, foram coletadas e georreferenciadas 41 amostras de fezes da área de estudo. Através da distribuição das amostras é possível inferir que as antas utilizam a área de floresta plantada de acordo com a disponibilidade do ambiente. O DNA de todas as amostras foi extraído e os locos microssatélites de interesse foram testados. Dez locos microssatélites foram testados, sendo que deste total cinco se mostraram mais eficientes, ou seja, foi possível realizar sua amplificação na grande maioria das amostras utilizadas e a genotipagem apresentou uma boa qualidade, possibilitando uma identificação confiável dos alelos. As amostras com o genótipo definido para pelo menos três locos foram selecionadas e analisadas no programa GIMLET para identificação individual e estimativa da PID (Probabilidade de Identidade) e nos programas FSTAT e GenAlex para estimativa da diversidade genética. Dentre 23 amostras analisadas, foram identificados 20 indivíduos, sendo 14 machos, 3 fêmeas e 3 de sexo indeterminado. A recaptura de três indivíduos possibilitou a verificação da movimentação destes pela área. O presente estudo mostrou, então, que as antas (Tapirus terrestris) utilizam as florestas plantadas de Eucalyptus... (Resumo completo, clicar acesso eletrônico abaixo)

Identificação molecular e genotipagem pela técnica de Spoligotyping de Mycobacterium tuberculosis isolado da população indígena e não-indígena no Mato Grosso do Sul (MS)

O presente trabalho baseou-se na análise de amostras de isolados de M. tuberculosis provenientes da população indígena e não indígena do Mato Grosso do Sul. As análises foram feitas basicamente por três técnicas de Biologia Molecular: PCR-IS6110 e PRA (para identificação) e Spoligotyping (para genotipagem), ressaltando que somente as amostras negativas para PCR-IS6110 foram submetidas ao PRA. Os objetivos do estudo eram: confirmar por técnicas moleculares de PCR e de PRA a identificação do complexo M. tuberculosis e de outras micobactérias, após o descongelamento e cultivo, analisar a incidência de isolados de M. tuberculosis da região do Mato Grosso do Sul que não tem o IS6110, avaliar a incidência de outras micobactérias entre a população indígena e não indígena do Mato Grosso do Sul, agrupar em famílias, por similaridade epidemiológica os isolados de M. tuberculosis procedentes da população indígena e não indígena com TB e avaliar a presença efetiva de grupos genéticos predominantes; Pela técnica de PCR-IS6110, analisamos um total de 119 isolados clínicos, sendo que apenas 6 apresentaram negatividade, sendo assim submetidos à técnica do PRA. Feito isso, também apresentaram resultado positivo para CMTB, nos permitindo concluir que essas técnicas podem se tornar ferramentas de grande valia no diagnóstico rápido da TB. Pela técnica de genotipagem do Spoligotyping foram analisadas 97 amostras e foi constatado um maciço predomínio da família LAM, principalmente da subfamília LAM 9, representados por 4 SITs, sendo SIT 42 com 44 isolados e SITs 177, 1337 e 1075 com respectivamente 4, 2 e 1 isolados cada (essa subfamília representou 52,6% do total de isolados). Outras famílias, tais como T, H e U também estiveram presentes no estudo em menores proporções
