Dunging gutters filled with fresh water in finishing barns had no effect on the prevalence of Salmonella enterica on Brazilian swine farms

Our aim was to assess the importance of dunging gutters filled with water in finishing barns for the prevalence of pigs shedding Salmonella enterica. Some finishing barns in Brazil are provided with a dunging-gutter system which consists of a continuous water flow at the back of solid-floored adjacent pens. Because there is transfer of faecal material between adjacent pens by water in this system and the faecal-oral route of transmission is so important for enteric pathogens, we tested the hypothesis that the presence of this kind of dunging-gutter system in finishing barns affects the prevalence of slaughter-age pigs shedding salmonella organisms in their faeces. The cross-sectional study was conducted on six farms each having barns with and barns without a dunging-gutter system. Breeding, management, nutritional and seasonal factors were similar in both barns on each farm. The two systems did not differ in prevalence of pigs shedding salmonella organisms. Five S. enterica scrotypes were isolated: S. Agona, S. Javiana, S. Rissen, S. Sandiego and S. Senftenberg. (C) 2002 Elsevier B.V. B.V. All rights reserved.

Hemangiosarcoma of the nictitant membrane in a Brazilian Fila dog: case report

Relata-se o caso de um cão, macho, da raça Fila Brasileiro, com nove anos de idade, acometido por neoformação tecidual na membrana nictitante do olho direito, com cerca de quatro meses de evolução. Realizou-se exame oftálmico rotineiro, a partir do qual se notaram hiperemia e edema conjuntivais, secreção ocular serossangüinolenta e neoformação saliente na conjuntiva da membrana nictitante. Realizou-se a exérese cirúrgica da neoformação. À histopatologia, encontraram-se células endoteliais pouco diferenciadas e pleomórficas que originavam intensa neoformação vascular, compatíveis com hemangiossarcoma da membrana nictitante.

A revision of the genus Pulaeus Den Heyer, with descriptions of a new genus and four new Brazilian species (Acari: Prostigmata: Cunaxidae)

A new genus, Lupaeus gen. nov., is created to contain part of the described species in the genus Pulaeus Den Heyer. A key to the genera of the tribe Pulaeini, to which these two genera belong, and one auxiliary key to the species of Brazil and South Africa, are provided. Four new species, viz. Pulaeus myrtaceus sp. nov., P. quadrisolenidius sp. nov., Lupaeus lectus sp. nov. and L. lobidorsalis sp. nov. are described and figured. P. martini Den Heyer, 1981 is designated as type species for the new genus. New nomenclatural combinations are reported.

Morphological characterisation of five brazilian species of Fidicinoides (Hemiptera: Cicadidae)

The objective of this study was to describe and illustrate the morphological characteristics of some species of Brazilian Fidicinoides to aid in their identification. Descriptions and illustrations are given of the head, thorax, abdomen, right forewing and the last urostemite of the male of the Fidicinoides besti, Fidicinoides brunnea, Fidicinoides duckensis, Fidicinoides pseudethelae and Fidicinoides sucinalae species. The main diagnostic characteristics of these species are markings on pronotum and/or mesonotum and male stemite VIII characteristics.

Detection of Ehrlichia chaffeensis in Brazilian marsh deer (Blastocerus dichotomus)

Ehrlichia chaffeensis was detected for the first time in blood samples from Brazilian marsh deers (Blastocerus dichotomus) captured in the marshes of Parana River in Southeast Brazil in 1998. Seven EDTA-blood samples from deers were analyzed by PCR and nested PCR for presence of Ehrlichia chaffeensis, Ehrlichia ewingii, Ehrlichia canis, Neoriickettsia risticii, Anaplasma phagocytophilum and Anaplasma marginale. Three samples showed positive reactions for E. chaffeensis and Anaplasma marginale. None contained detectable A. phagocytophilum, E. ewingii, E. canis or Neorickettsia risticii DNA. In Brazil, the wild marsh deer may be a natural reservoir of the agents that cause human monocytotropic ehrlichiosis and ruminant erythrocytic anaplasmosis. (c) 2006 Elsevier B.V.

A história local e seu lugar na história: histórias ensinadas em Ceará-Mirim

This Researchis about history education and is directed toward the understanding of teacher practices in schools of the basic education in Ceará-Mirim, a city located in the state of Rio Grande do Norte. Its purpose is to understand the approaching forms of local history in 5ª to 8ª grade classrooms in the light of the recent innovations in the fields of the historiografy and education. The study was done with a view of investigating local history is being taught by teachers, as well as reflecting on the necessary conditions to the accomplishment of a teaching whose know how to make possible to break, on the one hand, with the limits of the narrow `local view`, and, on the other hand, with the globalized view, negating the local particularitities and especifications. Such questions had emerged as the understanding of what local history contents can constitute in a significant component in the production of school historical knowledge in 5ª to 8ª grade classrooms. History education is analyzed, considering the depositions of three teachers of Ceará-Mirim in reagard to its historiography conceptions and history as a school subject. This inquiry is of a qualitative nature and had as a main strategy of data construction from the interviews with the teachers. The analysis indicates the permanence of teacher practices who, even though presenting innovations, bring an implicit value hierarchy where the place or thematic places are not contemplated in the school contents or appear overwhelmed by general history and the Brazilian history, configuring itself as a hierarchical relation to problematic historical ones. Thus the necessity of having historical school knowledge, that considers the local especifications, without, however, ignoring the articulations with other spatial dimensions
