Morpho-structural characterization of rabbits of both sexes in the southeastern region of Brazil

Several studies have highlighted the importance of the correlation between body size and body weight. The objective of this study was to characterize the morphological structure of New Zealand White rabbits, phenotypically correlating body shape traits with body weight. For this purpose, forty rabbits, weaned at 35 days of age, were distributed in a completely randomized experimental design, consisting of two treatments (female and male) with twenty replicates each. At 88 days of age, animals were weighed to determine body weight (B W), and then the following body measures were determined using a measuring tape: ventral perimeter, thoracic perimeter, wither height, croup height, ear length, and body length. Average BW was 2,220 g, and average body measures were 34.4 cm, 28.4 cm, 8.95 cm, 10.4 cm, 10.6 cm, and 36 cm respectively. No significcmt differences between sexes were found relative to the studied traits. There was no negative correlation between body measures and BW, and, except for body length, all measures were significantly correlated with BW, with ear length and ventral perimeter presenting the highest values.

Analysis of Climatic Factors Impact on RSV Infection Distribution in Children Attending Childcare at Northwest Region of São Paulo, Brazil

Respiratory syncytial virus (RSV) was detected in samples collected from children from 0 to 6 years of age with acute respiratory infection, attending public childcare on Northwest region of São Paulo, Brazil. RSV distribution was associated to seasonal climatic variables as temperature, rainfall and relative air humidity. We utilized samples of nasopharyngeal aspirate collected during the period of July 2003 to September 2005. RT-PCR was the chosen method for viral identification. Results showed that from the 817 samples (collected from 179 children), 7.7% (63/817) were RSV positive. In 2003, RSV was detected from July until October. In 2004, RSV infections occurred in March, May, June, July, October, November, and December. In 2005, RSV was detected in March, April, May, August, and September. RSV circulation patterns in childcare children showed seasonal distribution associated to decreases in temperature and relative air humidity. RSV was detected in childcare children as an important viral agent causing respiratory infections, with varying patterns of circulation into the cohort during the study period. Moreover, RSV distribution showed to be associated with the dry season on Northwest region of São Paulo, Brazil.

Reference evapotranspiration models using different time scales in the Jaboticabal region of Sao Paulo, Brazil

The aim of this paper is to compare 18 reference evapotranspiration models to the standard Penman-Monteith model in the Jaboticabal, Sao Paulo, region for the following time scales: daily, 5-day, 15-day and seasonal. A total of 5 years of daily meteorological data was used for the following analyses: accuracy (mean absolute percentage error, Mape), precision (R-2) and tendency (bias) (systematic error, SE). The results were also compared at the 95% probability level with Tukey's test. The Priestley-Taylor (1972) method was the most accurate for all time scales, the Tanner-Pelton (1960) method was the most accurate in the winter, and the Thornthwaite (1948) method was the most accurate of the methods that only used temperature data in the equations.

Epidemiological profile of hepatitis C virus infection in patients from west region of Minas Gerais State, Brazil

Hepatitis C virus (HCV) is a serious public health problem and is the leading cause of liver transplantation due to cirrhosis and hepatocellular carcinoma. In Brazil, it is estimated that there are approximately 2 to 3 million HCV chronic carriers. Few data regarding HCV infection are available in West region of Minas Gerais State. Due to the absence of an effective vaccine against this important human pathogen and the high costs of antiviral treatment, it is important to conduct epidemiological studies with the purpose of carry out the planning and implementation of measures to prevent hepatitis C in different populations. Therefore, the aim of this study is to describe the epidemiological aspects of HCV patients from West region of Minas Gerais State, Brazil. Sociodemographic data and risk factors for HCV infection were determined from 74 HCV patients from Uberlandia city (Minas Gerais State). Reactive anti-HCV sera samples were submitted to HCV RNA and genotype detection. Most of individuals were male (63.5%) with mean age of 51 years and presenting low socioeconomic status. HCV genotype was determined among 40 samples and the frequencies were: genotype 2 (45%), 1 (37.5%) and 3 (17.5%). Hepatitis C virus (HCV) infection was common among male and low socioeconomic status individuals.

Seroprevalence of salmonella and mycoplasma in commercial broilers, backyard chickens, and spent hens in the region of Triangulo Mineiro, state of Minas Gerais, Brazil

Avian salmonellosis and mycoplasmosis are infectious diseases that, in addition of causing lack of flock uniformity, represent a hazard to human health. The objective of the present study was to evaluate the seroprevalence of mycoplasmosis and salmonellosis in commercial broilers, backyard chickens, and spent hens slaughtered at a processing plant with local health inspection in Uberlandia, MG, Brazil. A total of 210 samples were randomly collected at the time of bleeding. Samples were submitted to rapid plate serum agglutination test (RSA) for the classification of Salmonella pullorum, Salmonella gallinarum, Mycoplasma gallisepticum and Mycoplasma synoviae. In order to increase result specificity, mycoplasmosis-positive samples were submitted to hemagglutination inhibition test (HI). No samples presented detectable antibodies against Salmonella pullorum or Salmonella gallinarum in the RSA test. Only Mycoplasma synoviae was detected in 14% of the backyard chickens and 0.74% in commercial broilers, whereas no antibodies were detected in spent hens. The seroprevalence rates found in the present study emphasize the need of keeping chicken flocks free from disease using effective biosafety systems.
