The aim of this study was to retrospectively evaluate in the casuistry on class and systems frequently diagnosed in wild animals that were sent to the FMVZ-UNESP-Botucatu diagnostic imaging service. The class of birds was the most referred to the centers, followed by the mammals and reptiles. The majority of the requested tests were the radiographs and in a minor scale the tomography and ultrasound. Although the birds were the greatest number of animals sent to the service, mammals were the most radiographed for wound control. The most frequently observed system was the musculoskeletal caused by trauma, especially in birds. The radiograph was the most exam initially indicated, then the animal could be forwarded to other imaging modalities, which in wild animals medicine is still limited to research.

The traffic of wild animals can be identified as the main cause of finding captive animals in zoos and sorting centers in Brazil. The maintenance of these animals in captivity is usually justified by the prevention of total loss of individuals of that specie, if it becomes extinct in the wild, and also, the importance of these subjects in studies of basic biology of the species. Keeping animals in captivity environment brings the need to ensure the welfare of them. The high population density and limited space are some of the possible stressors that these individuals face in capivity. Even the low pressure feeding and food easily available could be stressors, since they change the budget activities typical of the specie, causing sedentary behavior and sometimes depression. The captive environment and activities related to it (handling, transport, social change and social isolation) could compromise the animal welfare. Reduction in life expectancy, impaired growth and reproduction, personal injury, illness, immunosuppression, exacerbated adrenal activity and abnormal behavior, are events often lonked to compromised welfare. Hence, assessment and promoter methods are used to provide the welfare to captive animals. The assessment can be made by hormonal and/or behavioral measures. Both are extremely important, and usually are used in combination, to provide more tangible results about the condition of the animal. The promotion of animal welfare can be accomplished through environmental enrichment, a technique which aims to provide a more complex and diverse environment, increasing the possibility of the animal express more natural behavior, or characteristic of the species. Thus, the objective of this dissertation is discuss the importance of animal welfare and the ways this can be evaluated and promoted... (Complete abstract click electronic access below)

Hematology has a great importance in assessing the health of all animals, including reptiles, since it aids in the diagnosis of certain diseases and help to monitor patient's clinical evolution, although studies and articles in this area are rare, even with the increasing number of calls of these animals in veterinary clinics. Moreover, there are a lot of environmental and individual factors, which influence the hematological values of this group, such as age, sex, stress levels, nutrient levels and season which the exam was made, among others. For these reasons studies that aimed to evaluate the reference values of some specie, are essential to increase the knowledge in the field and to assist on the clinical approach. This paper aim’s to study the patterns of Hematology of Tortoise (Geochelone carbonaria) seeking the greater knowledge of clinical pathology of this species and increasing the possibilities for diagnosis, monitoring clinical outcome, and assessment of the general state and treatment

Os carrapatos são ectoparasitas hematófagos que apresentam grande importância econômica e médico-veterinária por transmitirem patógenos para os diversos hospedeiros, bem como por causarem redução na qualidade da carne, couro e leite devido à sua ação espoliativa. A espécie Rhipicephalus sanguineus (Ixodidae), conhecida popularmente como “carrapato do cão” tem ampla distribuição geográfica e é a principal responsável pela transmissão de patógenos aos cães domésticos, além de ser potencial transmissora destes para a espécie humana. A espécie Ornithodoros rostratus (Argasidae) conhecida como “carrapato do chão” é encontrada principalmente na região centro-oeste do Brasil e tem causado problemas, tais como grandes hematomas na pele do hospedeiro, principalmente dos suínos e dos animais silvestres, além de humanos, devido a sua fixação. O tecido fluído desses animais é a hemolinfa, a qual é composta por plasma linfático e por diversos tipos de células, ainda pouco estudadas. A hemolinfa é responsável pelo transporte de diversas substâncias importantes para a sobrevivência do animal, tais como enzimas, hormônios e resíduos a serem excretados pelo organismo. O objetivo deste trabalho foi o de realizar uma descrição comparativa e detalhada das células encontradas na hemolinfa das duas espécies de carrapatos citadas

Novos hábitos alimentares da população e as mudanças nos sistemas de produção e distribuição dos alimentos podem estar fortemente relacionados aos casos de doenças transmitidas pelo consumo de alimentos contaminados por microorganismos. Isso faz com que a preocupação com a qualidade microbiológica dos alimentos aumente mundialmente. Dentre os principais patógenos, destaca-se a Salmonella sp, que pertence à microbiota gatrentestinal de animais silvestres e de animais domésticos criados para o consumo humano (aves, bovinos e suínos). Este fato torna o problema de grande relevância para as autoridades de saúde pública, pois esses microrganismos podem estar associados às infecções ou surtos provocados pela ingestão de alimentos contaminados. Foram coletadas 35 amostras de lingüiças e 25 cortes de frango, nos principais supermercados do município de Botucatu-SP e avaliados quanto à qualidade higiênico-sanitária através da determinação do número mais provável de coliformes termotolerantes (CT), além da presença de Salmonella sp. Os resultados obtidos mostram que 31% das lingüiças e 84% das amostras de frango estavam fora dos padrões higiênico-sanitários estabelecido pela ANVISA (RDC n° 12), que determina uma quantidade máxima de 5x103 CT/g em lingüiça e 104 /g em carne de aves. Em relação à Salmonella sp, estabeleceu-se a ausência dessa bactéria em 25g de lingüiça e não determina nenhum parâmetro para o frango. Entre as 25 amostras de frango analisadas, duas (8%) foram positivas pela metodologia tradicional. Esse... (Resumo completo, clicar acesso eletrônico abaixo)

A Organização Mundial de Saúde estima que existem cerca de 10 milhões de infectados pelo Trypanosoma cruzi, 30% dos infectados cronicamente desenvolvem alterações cardíacas, e 10% digestivas e neurológicas. O T. cruzi é um protozoário cinetoplástida flagelado agente etiológico da tripanossomíase americana, popularmente conhecida como a Doença de Chagas, uma antropozoonose conhecida na América Latina. Pelo menos 40 espécies de triatomíneos – conhecido por barbeiros – carregam o protozoário. O gênero Triatoma representa o principal vetor da Doença de Chagas e são adaptados a climas secos de ambientes rurais da América do Sul e Central. Outras formas de infecção podem ocorrer por transfusão de sangue, transplantes, via oral, e transmissão vertical. Há duas fases que caracterizam a infecção pelo T. cruzi: a fase aguda, apresentando um período de incubação de uma semana a um mês, que geralmente é assintomática. Já a fase crônica é mais polêmica e divide a opinião dos pesquisadores, mas basicamente mostra-se como uma cardiomiopatia chagásica, ou uma dilatação no trato digestivo e ainda pode causar lesões no sistema nervoso parassimpático e simpático. Entre essas duas fases ocorre um período indeterminado em que não há nenhuma manifestação clínica da doença. Existem teorias que explicam a patogenicidade das lesões da doença: uma postula que as lesões características da Chagas são referentes à ruptura das células parasitadas e subsequente inflamação. Outra é a teoria da autoimunidade, em que o próprio sistema imune do indivíduo rejeita as células livres de parasitas causando as lesões características da doença. Há evidências substanciais que comprovem a participação das respostas imunes nas lesões miocárdicas, mas como o parasito consegue desencadear estas respostas imunes, ainda não está esclarecido...

Currently zoos and management centers are valuable tools in the maintenance and study of various species. Studies of behavior of captive animals contribute to the improvement of management techniques and the well - being of themselves, encouraging captive breeding and reintroduction also to the natural environment . One of the ways to increase the levels of well-being is the use of environmental enrichment techniques that provide necessary incentives for the welfare of both physical and psychological captive animal . The aim of this study was to identify the types, frequencies and intensities of behavior displayed by three individuals of the species Galictis cuja, belonging to the family Mustelidae and popularly known as lesser grisson , which are captives in municipal zoo in Piracicaba , SP . In addition to evaluating the influence of environmental enrichment techniques on these behavioral parameters. The animals had their behaviors recorded in ethograms through the focal sampling method , 40 hours per person , totaling 120 hours of observation . Were introduced four environmental enrichment techniques related to physical environment, nutrition , perception and cognitive stimulation . At the end, the results of observations before and after the introduction of enrichment techniques were compared and it was possible to observe significant changes in behavior such as run , walk and scratching . The animals were more active and spent longer visible during the day, the enrichment also increased the frequency of social behaviors and the end of the work occurred even attempted copulation , thus showing that the enrichment exerted a positive influence on the behavioral patterns of lesser grisson (Galictis cuja)

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)
