Terahertz Spectroscopy Applied to Diagnostics in Public Health: A Review
Almeida,Meila Bastos de; Schiavo,Letícia; Esmanhoto,Elis; Lenz,Cesar Antonio; Rocha,Jaime; Loureiro,Marcelo; Kmetiuk,Louise BachAbstract Terahertz (THz) spectroscopy is an emerging technology that is that is bringing a number of technical breakthroughs in several scientific applications. This review aimed to describe potential applications of THz spectroscopy at the biochemistry and molecules detection for food industry, environment monitoring and diagnostics, and present the importance of such technological platform in disease control ...
DINÂMICAS PRÉ E PÓS-COLOSTRAL DO ERITROLEUCOGRAMA, DA PROTEÍNA PLASMÁTICA TOTAL...
Souza,Damaris Ferreira de; Kowalski,Luciana Helena; Kulik,Carlos Henrique; Barros Filho,Ivan Roque de; Dittrich,Rosangela LocatelliResumo O objetivo deste estudo foi caracterizar a dinâmica de alguns parâmetros hematológicos em cordeiros recém-nascidos sadios, antes e após a ingestão de colostro. Foram coletadas amostras sanguíneas de 28 cordeiros recém-nascidos, determinando-se o eritroleucograma, as concentrações de proteína plasmática total (PPT) e de fibrinogênio nos momentos pré e pós-colostro. Os dados foram analisados comparando-se ...
Encefalopatia espongiforme bovina atípica: uma revisão
Laurindo,Ellen Elizabeth; Barros Filho,Ivan Roque deRESUMO: A encefalopatia espongiforme bovina (EEB), causada por um príon infectante, surgiu na década de 1980 na Europa como uma nova doença nos rebanhos bovinos e, desde então, estão sendo tomadas várias ações para sua prevenção e controle. A restrição da alimentação de ruminantes com subprodutos de origem animal e a remoção e destruição dos materiais de risco específico para a doença das carcaças em frigorífic...
Comparison between three techniques for videosinuscopy in cattle
Basso,Fernando Zanlorenzi; Busato,Eduarda Maciel; Silva,Jéssica Rodrigues da; Guedes,Rogério Luizari; Barros Filho,Ivan Roque deABSTRACT: Cattle have extensive paranasal sinuses that are susceptible to disease, most commonly sinusitis. The sinuscopy can be used to evaluate these structures, although there are no descriptions of this region for endoscopic anatomy, especially regarding the trocar position and the most appropriate type of endoscope. This study aimed to standardize the surgical approaches to sinuscopy in cattle by comparing...
Occurrence of antibodies anti -Toxoplasma gondii, Neospora caninum and Leptospi...
Zimpel,Cristina Kraemer; Grazziotin,Ana Laura; Barros Filho,Ivan Roque de; Guimaraes,Ana Marcia de Sa; Santos,Leonilda Correia dos; Moraes,Wanderlei deAbstract A large number of Brazilian zoos keep many endangered species of deer, however, very few disease surveillance studies have been conducted among captive cervids. Blood samples from 32 Brazilian deer (Blastocerus dichotomus, Mazama nana and Mazama americana) kept in captivity at Bela Vista Biological Sanctuary (Foz do Iguaçu, Brazil) were investigated for 10 ruminant pathogens, with the aims of monitorin...

Morikawa,Vivien Midori; Zimpel,Cristina Kraemer; Paploski,Igor Adolfo Dexheimer; Lara,Maria do Carmo Custódio de Souza HunoldBarbary sheep (Ammotragus lervia) have the potential to act as hosts of important infectious diseases, particularly zoonoses. Blood samples from 17 Barbary sheep at the Curitiba zoo were collected to evaluate occurrences of anti-Toxoplasma gondii and anti-Neospora caninum antibodies, tested using the indirect immunofluorescence antibody test (IFAT). Anti-T. gondii and anti-N. caninum antibodies were detected in...
Detection of anti-Toxoplasma gondiiantibodies in carthorses in the metropolitan...
Finger,Mariane Angélica; Villalobos,Eliana Monteforte Cassaro; Lara,Maria do Carmo Custódio de Souza Hunold; Cunha,Elenice Maria SequetinToxoplasma gondii, the agent for toxoplasmosis, has worldwide distribution. Horses normally play a secondary role in its life cycle, but movement around urban areas, feeding on grass and the increasing use of carthorses for gathering recyclable material in some urban areas of Brazil may increase their exposure to T. gondii infection. The aim of the present study was to investigate the frequency of anti-T. gondi...
Detection of Neospora sp. antibodies in cart horses from urban areas of Curitib...
Villalobos,Eliana Monteforte Cassaro; Furman,Keiko Endo; Lara,Maria do Carmo Custódio de Souza Hunold; Cunha,Elenice Maria SequetinNeospora caninum is a protozoan parasite which affects dogs as definitive hosts and several mammalian species as intermediate hosts mainly causing abortions and central nervous system disorders. The reemerging population of cart horses for carrying recycling material in urban areas of major cities in Brazil may have an impact on disease spreading, and these animals may be used as sentinels for environmental sur...

Costa,Joselito Nunes; Benesi,Fernando José; Birgel,Eduardo Harry; D'Angelino,José Luiz; Ayres,Maria Consuelo Caribé; Barros Filho,Ivan Roque dePara avaliar-se a influência dos fatores etários sobre o leucograma de fêmeas zebuínas da raça Nelore, examinaram-se amostras de sangue de 158 animais, distribuídos por sete grupos etários ( até 3 meses; 3 a 6 meses; 6 a 12 meses; 12 a 24 meses; 24 a 48 meses; 48 a 72 meses e maior que 72 meses). Os resultados expressos em valores médios (± desvios padrões) máximo (máx.) e mínimo (mín.) em milhares de células p...
