PREVALENCE OF ANTIBODIES TO TRYPANOSOMA CRUZI, LEISHMANIA INFANTUM, ENCEPHALITOZOON CUNICULI, SARCOCYSTIS NEURONA, AND NEOSPORA CANINUM IN CAPYBARA, HYDROCHOERUS HYDROCHAERIS, FROM SAO PAULO STATE, BRAZIL

Little is known about the importance of capybara. Hydrochoerus hydrochaeris, as reservoirs for parasites of zoonotic or veterinary importance. Sera from 63 capybaras, from 6 counties in the state of Sao Paulo, Brazil, were examined for antibodies to Trypanosoma cruel, Leishmania infantum, Encephalitozoon cuniculi. Sarcacystis neurona, and Neospora caninum using an indirect immunofluorescent antibody test. Five (8%) of the 63 capybaras had antibodies to T cruzi epimastigotes. None of the samples from capybara reacted positively with L. infantum promastigotes or with spores of E. cuniculi. Two (3%) of the serum samples were positive for antibodies to S. neurona merozoites, and 2 (3%) of the serum samples were positive for antibodies to N. caninum tachyzoites. A serum sample from 1 capybara was positive for antibodies to both T cruzi and N. caninum. None of the remaining 62 samples reacted with more than 1 parasite.

Nuclear morphometry in cytopathology: a prognostic indicator for canine cutaneous mast cell tumors

Twenty-nine canine cutaneous mast cell tumors (MCTs) were morphometrically analyzed with regard to mean nuclear area (MNA) using cytopathology smears. The results showed a correlation between MNA and survival. When graded into 2 morphometrically different groups, there were statistically significant differences among high- and low-grade MCTs, regarding both Romanowsky-type stain and hematoxylin and eosin. Cytomorphometry could also separate histologic grade II tumors with better prognosis from the more aggressive MCTs. The results indicated that nuclear morphometry on cytopathology preparations can predict the biological behavior of cutaneous MCTs in dogs in an independent manner, yielding a rapid and reproducible diagnosis, which renders the method useful for veterinary oncology.

Massive infestation by Perulernaea gamitanae (Crustacea: Cyclopoida: Lernaidae) in juvenile gamitana, cultured in the Peruvian Amazon

The gamitana is a species of socio-economic importance in the Peruvian Amazon, often intensively produced locally for human consumption. Because of this, more studies concerning parasite populations affecting this species culture are necessary. In this study, a heavy copepod infestation of Perulernaea gamitanae is reported in a managed culture of gamitana. The prevalence of infection was 100% and mortality of the fish population was complete. The average intensity and abundance of the parasite was 268.8 parasites per individual.

REDUCED ERYTHROCITARY GLUTATHIONE AND HEINZ BODIES IN CATS EXPERIMENTALLY INFECTED WITH THE FELINE IMMUNODEFICIENCY VIRUS

Santos, K.B.; Daniel, A.G.T. & Hagiwara, M.K. [Reduced erythrocitary Glutathione and Heinz bodies in cats experimentally infected with the Feline Immunodeficiency Virus.] Glutationa Reduzida Eritrocitaria e Corpusculos de Heinz em gatos infectados experimentalmente pelo Virus da Imunodeficieneia Felina. Revista Brasileira de Medicina Veterinaria, 30(1):26-30, 2008. Centro Universitario Serra dos Orgaos, Rua Comendador Queiroz 52, Apto. 1403, Niteroi, RJ 24230-220, Brasil. E-mail: keilabsantos@)gmail.com The Feline Immunodeficiency Virus (FIV) produces a chronic infection with immunologic system disfunctions in domestic cats developing non-responsive anaemia. The feline immunologic status depression produces free radicals, whose imbalance between production and removal in the organism favour the oxidative injury occurrence. Heinz bodies in large amounts also can evident in vivo oxidative damage. Glutatione, a tripeptide found in the animal cells, is an important protection mechanism against oxidative damages. In this work erythrocyte reduced glutathione (GSH) concentrations for healthy and cats experimentally infected by FIV were determinated in relation to the hemogram and the Heinz bodies presence. All of the animals presents normal values for hemogram and Heinz bodies, however the GSH erythrocyte concentrations in the FIV positive cats were below the normality probably due to an passive depletion to GSH.

Twenty five cats male and famale with variable degrees of gingivitis were included in this study. The samples were colected by culturette swabs and submitted to bacterial culture and sensitivity. The results showed that 91% of the bacteria isolated from the culture were sensitive to enrofloxacin, demonstrating that this antibiotic is a good option in the clinical treatment or post-operative treatment of feline chronic gingivitis.

First isolation and molecular characterization of Ehrlichia canis in Costa Rica, Central America

The present study investigated Ehrlichia species in blood samples from dogs suspected of clinical ehrlichiosis, using molecular and isolation techniques in cell culture. From a total of 310 canine blood samples analyzed by 16S rRNA nested PCR, 148 (47.7%) were positive for Ehrlichia canis. DNA from Ehrlichia chaffeensis or Ehrlichia ewingii was not detected in any sample using species-specific primers in separated reactions. Leukocytes from five PCR-positive dogs were inoculated into DH82 cells; successful isolation of E. canis was obtained in four samples. Partial sequence of the dsb gene of eight canine blood samples (including the five samples for in vitro isolation) was obtained by PCR and their analyses through BLAST showed 100% of identity with the corresponding sequence of E. canis in GenBank. This study represents the first molecular diagnosis, isolation, and molecular characterization of E. canis in dogs from Costa Rica. (C) 2010 Elsevier Ltd. All rights reserved.

Trajetória do crescimento da cidade de Colatina

It approaches the growth of the city of Colatina-ES, the county seat that has urban economy and urban population, and territory with most of the rural area. Rural areas, however, contribute little to the city s economy and are largely environmentally degraded, idle and waiting for recovery. The objective is to understand the growth of the city of Colatina, and the factors and consequences of this growth. Land division projects, investments and interventions in urban and rural areas were collected for the analysis. As a median-sized city characterized by central and regional polarity, but outside of the main investments in the state, Colatina seeks to take advantage of its situation of commercial warehouse city and road junction to stay alive in the regional economy. The citys economy is based on trade and services, but seeks to attract investment to the industry and logistics. The expansion of the city since the early formation follows the road system, which creates a dispersed spatiality. The characteristics of the urban growth of Colatina are the result of economic development strategies, interests in the property market and a government that abstains from urban control. These factors lead a sprawl urbanization that presents itself costly and not sustainable for urban and rural areas because it creates segregation, higher infrastructure costs, low-density and monofunctional urban spaces, pollution, and worsening of environmental depletion. The challenges for sustainable growth of the city of Colatina depends on a municipal and regional planning, which qualifies and diversifies its urban areas, avoids unnecessary expansion of the urban perimeter, retrieves its environmental degraded areas and leverages the agricultural activities in a productive and less aggressive way to the environment

Ocupação urbana em áreas de preservação permanente : o caso do manguezal da área continental de Vitória/ES

This research aims to diagnose the environmental impacts caused by the growth of urban occupations over the mangrove in the continental area of Vitória. It is justified by the gradual degradation of mangroves in Vitória that has inestimable importance to the landscape, to the environment and to the economy. With the growth of urban population in Brazil and around the world, researches like this, about environmental management, are essential to allow cities to grow more sustainably and well planned. The thesis was initially based on the study of occupations of Permanent Preservation Areas in general, with the presentation of the basic concepts and reflections, and later on territorial analysis of some protected areas and their surroundings, and the study of the empirical object, a polygon that covers urban areas and mangroves on the continental part of Vitória. The study hopes to promote a reflection and a discussion about the importance of maintenance of protected natural areas inside the cities, generating knowledge about the importance of mangrove and diagnose how it has been urbanized, protected or degraded over the years

Fluxos globais e intra-urbanos : subsídios para seu planejamento em Vitória

One is about a study of the interactions and conflicts between the distinct scales of the flows of the global production and urban mobility on the territory of the city, particularly of Vitória, Espírito Santo. From this analysis of the consequences of the new technologies of the information, of the communication and the transports on the economic and humans relations, if it considers the study of the characteristics of the two layers that act on the territory. Of the scale of the global production, the impacts of the great corporations, its physical nets and its force had been considered as territorial agent in the creation and sponsorship of plans. In the analysis of the place, the intra-urban movements of human displacements e had been considered, mainly the reasons of the trips. From the overlapping of the above-mentioned layers if it looked for to observe the interactions, conflicts and synergies between the layers the intervention in the flows demand of a coherent planning of the atract regions of trips, so that areas with infrastructure lack and services of public transport are not overloaded. Finally, as objective generality, generate with the basis in the interactions found in the overlapping, a list of subsidies for the planning of the urban flows.

Cidade-paisagem : novas perspectivas sobre a preservação da paisagem urbana no Brasil

The edification of the landscape in the scientific and social field, in speech as in the method, is taken in this study as a complex process, from which were developed relationships of dominance on the perception of space, which persist strongly consolidated, since the genesis of the conceptual practice till its actual praxis. Historically, the landscape studies took place slowly, immersed in many questions, in face of the multiplicity of meanings that the concept offers. In the psyche, the notion of landscape is present since a long time ago, as an unconscious human being practice, even before any ideological hypothesis formulation. However its materialization in the social conscious will come only from painting, and specially with the perspective, through the technicity of the view, at first wandering the infinity, now ordained in a frame‟. Since then, the landscape is perceived according to the order of the view, as the equivalent of nature and beauty, assuming at the same time, an important symbolic value, since it is linked to mnemonic and subjective processes that the being build with the territory. The domain on this space-cognitive experience, characteristic of the contemporary, consolidates in the social imaginary, building consensus on the landscape, whose aesthetic references make a cultural appeal, very pertinent to the actual capitalist dynamics of production the space worldwide, mainly of the spectacle and commodification of cities promoted by the city marketing. In Brazil, this consensual ideology of the landscape surpass the social imaginary and also dominates the political imaginary, whereas the main instrument for preserving the landscape, Decree-law 25, from November 30, 1937, and its limit to those of exceptional value or remarkable feature. The analysis of the processes for putting under governmental trust for inscription of goods by the landscape value, reveals the dominant, if not exclusive, adoption of selection criteria related to aesthetic aspects. Abstain, therefore, from what the nation considers patrimony , other landscapes that, besides not having, at first, remarkable aesthetic value, play a crucial role as an inheritance from ancestor relations between man and space and pre- existing condition for the same present and future relations. From this historical background, the research seeks to transfer into contemporaneity, the ideological analysis of the concept and its relation with the building of the landscape in the collective imaginary, in order to recognize, in current practices to landscape preservation, as much this genesis, rooted in aesthetics, remains strongly consolidated, feeding the current dynamics of consumption and commodification of the city. Therefore, as preliminary conclusion, one can state that the identification of landscapes of different value, especially aesthetic, maintains and intensify the treatment of the city as an object, a standard‟ commodity to be sold / traded on the world market, in detriment of its recognition as a dynamic process that, even though inserted in the global context, develops specificifities and peculiarities, inherent to the production of space, as Lefebvre preconizes, that is, to the production of life, social product , as characteristic, dissent generator

O novo paradigma do saber e os dispositivos urbanos para uma cidade educadora

Discusses the formation of urban apparatus that have characterized promote interaction, connection, inclusion and learning within the new paradigm of knowledge, which corresponds to the process of involvement/ knowledge propagation between space and urban space, caused by various combinations. Rescues the importance of physical space in the contemporary city before the increasing spread of cyberspace as one that many theorists seem to be the future of humanity. It also discusses the importance of knowledge in various fields such as Philosophy, Sociology, Education, and especially the Architecture and Urbanism, highlighting the need to think about the city according to this status of knowledge. Shows how the apparatus are found in urban public policy agenda. In this context, used as a model the polygonal 1 of the city of Vitória, consisting of eight communities that call themselves Território do Bem, focusing on how ownership and endogenous production of spaces contribute to the formation of urban apparatus. Also shows the performance of the city of Vitória through the Multiyear Plan 2010/2013, pointing out the actions and the programs that contribute to the formation of urban apparatus. The results show that the apparatus are tools of participatory urban management and city planning, contributing to the process of autonomy and social emancipation

A dimensão urbana da arquitetura : ambientes de transição

The present work aims to discuss the urban dimension of architecture and to investigate the role of the architectural spaces in the quality of life in between buildings and their environments. It investigates the transitional spaces between building and thoroughfare; building, thoroughfare and built environments located on the ground level of the buildings, and the potential they have to modify (individually or in groups) the environment where they are. For that, the research studies aspects of the architecture that urban buildings (individually or in groups) have and the inference of the morphology, building type and urban environment quality within the extended context of the Brazilian contemporary city. The analysis of the relation between building, thoroughfare and adjacent surroundings will be performed by the lights of, the evolution they have suffered since European urban spatial interventions that took place in the 19th Century; the morphological rupture on the traditional modern city of the 20th Century; the Brazilian experience focused on edifices, by showing analysis of a group of buildings, in their majority, iconic examples of Brazilian architecture from the 1930s onwards; and finally by an extensive investigation on the micro areas that have been selected in the Camburi region, in the city of Vitória-ES, focused on the characteristics of their architectural complex. As a preliminary conclusion, it can be stated that architecture cannot determine the quality in urban life and in its environments by itself, but because of its architectural and urban configuration of space, it may contribute to quality of environment in its surroundings

Desarrollo y aplicación de biotecnologías de la reproducción en ganado caprino, ovinos y camélidos

Las técnicas especiales de reproducción (inseminación artificial y transferencia de embriones) resultan auxiliares importantes para los planes de mejoramiento genético. En ovinos y caprinos están desarrolladas las técnicas, pero los resultados son aún deficientes con semen congelados, y las transferencias de embriones dan resultados erráticos. En cambio, en Camélidos sudamericanos no se posee una técnica confiable para inseminación y la transferencia de embriones es aún incipiente. En el presente proyecto se tratan de obtener técnicas de inseminación con semen fresco y congelados en ovinos y caprinos de acuerdo a nuestra realidad productiva, y en Camélidos Sudamericanos lograr el desarrollo de la técnica. Los trabajos se realizan simultáneamente en la Pampa y en Río Negro y se aplican en simultáneo en los mismos lugares donde se hace la investigación. Los pasos del trabajo consisten en recolección con vagina artificial, dilución y expansión, congelamiento, evaluación y siembra. La siembra requiere sincronización de celo en caso de ovinos y caprinos y estímulo de ovulación en el caso de Camélidos. Se trabaja con instalaciones simples diseñadas ad hoc y con el apoyo de un laboratorio portátil que consta de los elementos básicos para realizar el trabajo. La evaluación se hace finalmente en el laboratorio de Teriogenología de la Universidad Nacional de Comahue, Fac. De Ciencias Agrarias.
