Indicadores biológicos séricos em veado-campeiro ( Ozotoceros bezoarticus bezoarticus, Linnaeus 1758) de vida livre do Pantanal Sul-Mato-Grossense / Serum biological indicators in free-living pampas deer (Ozotoceros bezoarticus bezoarticus, Linnaeus 1758) of the Pantanal Sul-Mato-Grossense

O objetivo com este estudo foi estabelecer os intervalos de referência de diferentes analitos séricos em Ozotoceros bezoarticus bezoarticus de vida livre. Foram coletadas amostras de sangue de 54 fêmeas e 14 machos adultos, capturados no Pantanal de Mato Grosso do Sul. A determinação das concentrações de cálcio total, albumina, colesterol total, creatinina, glicose, fósforo, proteína total, triglicerídeos e ureia séricas e a atividade das enzimas alanina aminotransferase, aspartato aminotransferase, creatina quinase fração MB e fosfatase alcalina foi realizada em equipamento automático. Valores de globulinas, cálcio total e proporções (razões) entre analitos foram realizados por meio de cálculo matemático. Esta é a primeira descrição do intervalo de referência de parâmetros bioquímicos séricos em veado-campeiro de vida livre do Pantanal de Mato Grosso do Sul. O tamanho da amostra e a distribuição dos dados indicam que os valores médios obtidos são representativos e podem ser usados para a monitorização da saúde, do estado nutricional e do diagnóstico de enfermidades nesse estrato populacional.(AU)

The objective of the present study is to establish the reference intervals of different serum analytes in free - living Ozotoceros bezoarticus bezoarticus. Blood samples were drawn from the 54 females and 14 males, adults, captured in the Pantanal of Mato Grosso do Sul. A determination of total calcium, albumin, total cholesterol, creatinine, glucose, phosphorus, total protein, triglycerides, and serum urea concentrations and an activity of the enzymes alanine aminotransferase, aspartate aminotransferase, creatine kinase MB fraction and alkaline phosphatase were performed in automated equipment. Values of globulins, total calcium and proportions among analytes were performed by means of mathematical calculations. This is a first description of the reference parameters for serum biochemistry of free - living pampas deer in the Pantanal of Mato Grosso do Sul. Sample size and distribution of data indicate that the mean values obtained are representative and can be used for a health monitoring, nutritional status, and diagnosis of diseases in this population stratum.(AU)

Sorodiagnóstico de doenças da reprodução em rebanhos de bovinos leiteiros de assentamentos rurais de Corumbá, MS / Reproductive diseases serosurvey in dairy cattle from rural settlements of Corumbá city, Mato Grosso do Sul state, Brazil

This investigation was carried out in dairy cattle from four rural settlements of Corumbá, MS, Brazil, in order to assess the seroprevalence of bovine herpesvirus 1 (BoHV-1), bluetongue virus (BTV), and Leptospira; and the prevalence was 50.9 per cent (179/352), 51.3 per cent (181/353), and 35.8 per cent (125/349), respectively. Association between frequency of seropositive animals and evaluated rural settlements (P<0.01) was found for Leptospira, and indicated the influence of environmental factors in bovine infection. Age was significantly related to BoHV-1 (P<0.001), BTV (P<0.001), and Leptospira infection (P<0.01), showing higher number of infection among older animals. Once the bovine herds were not vaccinated, the presence of seropositive animals indicated that these infections occurred in rural settlements herds of Corumbá assayed, and certainly induced economical loss.(AU)

Sorologia para o vírus da língua azul em bovinos de corte, ovinos e veados campeiros no Pantanal sul-mato-grossense / Bluetongue virus serosurvey in beef cattle, sheep, and pampas deer from Brazilian Pantanal

This investigation was carried out in beef cattle (n=219), sheep (n=55), and pampas deer (Ozotoceros bezoarticus) (n=49) from Nhecolândia, sub region of Brazilian Pantanal in Mato Grosso do Sul State, Brazil. It was aimed to assess the seropositivity of these species to bluetongue virus (BTV) by agar gel immunodiffusion test. Seropositivity rates were 42.0% for cattle and 10.9% for sheep. The pampas deer showed to be all seronegative. In cattle, seropositivity to BTV significantly increased with age (P<0.001). These data, the favorable environmental conditions to development of BTV vectors, and the bovine reproductive disorders reported by farmers may indicate that BTV infection occurrs in herds of Brazilian Pantanal, and probably induces to economical losses.(AU)

Campilobacteriose genital bovina em rebanhos leiteiros com problemas reprodutivos da microrregião de Varginha - Minas Gerais / Bovine genital campylobacteriosis in dairy herds with reproductive problems of the microregion of Varginha, MG, Brazil

The frequency of bovine genital campylobacteriosis (BGC) in 157 cows from nine herds from the microregion of Varginha - Minas Gerais - Brazil was evaluated. Farmers use either artificial insemination and natural breeding after two insemination procedures or natural breeding. The diagnosis of BGC was performed by the direct fluorescent antibody test (DFAT) using vaginal mucus. All studied herds showed C. fetus infected animals and, of 157 animals, 40 (25.5 percent) were positive in DFAT: 7 (26.9 percent) from herds with natural breeding and 33 (25.1 percent) from herds with both artificial insemination and natural breeding after the second-to-third insemination. The high frequency of BGC found in this study shows that this disease is present among herds which have reproductive problems and the use of natural breeding after the second-to-third unsuccessful insemination could be a risk factor for the disease.(AU)
