Presença de anticorpos da classe IgM de Leptospira interrogans em animais silvestres do Estado do Tocantins, 2002

Abstract

A leptospirose é uma doença de importância mundial com implicações na saúde pública e animal, capaz de promover quadros infecciosos e grandes perdas econômicas. Os roedores constituem um dos principais reservatórios das espiroquetas, transmitindo a doença aos humanos e diferentes espécies animais 8 .Algumas espécies animais são reservatórios de importantes sorovariedades de Leptospira interrogans. Os mais freqüentes em bovinos são hardjo, wolffi, icterohaemorrhagiae, pomona, grippotyphosa, copenhageni e bratislava; em suínos bratislava, ABSTRACTFour hundred and twenty-seven serum samples of wild animals were tested against 18 serovars of Leptospira interrogans. Of 286 samples of Cebus apella, 46 (16.1%) were positive for the serovars pomona, brasiliensis, mini, swajizak, grippotyphosa, sarmin, fluminense, autumnalis, hebdomadis, guaratuba, javanica and icterohaemorrhagiae. Of 82 samples of Alouatta caraya, 2 (2.4%) were positive for the serovars mangus and fluminense. Of 31 samples of Nasua nasua, 4 (12.9%) were positive for the serovars fluminense and javanica, and of 10 samples of Cerdocyon thous, 2 (20 %) were positive for the serovars fluminense and brasiliensis. Seven samples of Dasyprocta sp, 6 of Tamandua tetradactyla and 5 of Euphractus sexcintus did not present reactivity.

Occurrence of antibodies against Leptospira spp. In free-ranging wild canids from the Brazilian savanna

“…Studies conducted in Brazil show that some crab--eating foxes are positively reactive to several serovars of Leptospira spp., as observed in this study as well as by Souza-Júnior, Lobato & Lobato (2006) and Jorge (2008). The serovars Autumnalis, Copenhageni, and Grippotyphosa, found in crab-eating foxes in this research have also been reported in earlier studies (Esteves et al 2005, Jorge 2008, Pimentel et al 2009).…”

“…The high frequency of low titers found in this study is common in most studies (Girio et al 2004, Esteves et al 2005, Souza-Júnior et al 2006, Silva et al 2010. Wild carnivores are sentinels for leptospirosis (Millán et al 2009), indicating the occurrence of the disease in the environment.…”

“…Reports of the serovars Wolfii and Icterohaemorrhagiae in crab-eating foxes were not found, so this represents the first record. Serovars other than those detected in this study have been described in Cerdocyon thous (Corrêa et al 2004, Souza-Júnior et al 2006, Jorge 2008, Ullmann et al 2012 (Table 3). …”

Biometric Measures, Body Score and Body Mass Index Evaluation in Wild Coatis (Nasua Nasua) Living in the South-Central Region of São Paulo State, Brazil

“…Studies focused on assessing the diet of wild coatis, as well as the effects of anthropogenic interaction, are lack in the literature [11]. Because these animals are easily adaptable, the over population of these species can lead to adverse consequences for both the environment and the public health, since they participate in zoonotic transmission cycles and are often found in zoos [12]. Therefore, it is important knowing their diet and behaviors in order to formulate their diet and to distinguish possible nutritional and behavioral affections [16].…”

<b>Caracterização de proteínas secretadas por <i>Leptospira </i>spp. e sua possível aplicação no diagnóstico da leptospirose</b>

“…A leptospirose é uma zoonose de importância mundial com grandes implicações na saúde pública animal e humana, e na economia devido aos prejuízos na agropecuária, além dos custos hospitalares e perdas de dias de trabalho. É causada por leptospiras patogênicas (SAENGJARUK et al, 2002;SOUZA JÚNIOR et al, 2006), e mais comumente encontrada em regiões tropicais e subtropicais, nas quais as condições ambientais favorecem a sobrevivência e transmissão das leptospiras, estando associada à umidade, condições precárias de infraestrutura, alta incidência de roedores e diagnóstico tardio (ABGUEGUEN et al, 2008;LAU et al, 2010;NABITY et al, 2012). De acordo com dados epidemiológicos, o Brasil encontra-se entre os países considerados de alto risco para a incidência da doença (LEVETT, 2004;LAU et al, 2010).…”
