Outbreaks involved at least 1,179 animals and cattle were the most affected animal species (76.8%). The numbers of reported neurological syndromes and of rabies outbreak shad strong positive correlation and exhibited decreasing linear trend.

One of the justifications for this spatial distribution may be related with the distribution of the animals in the state, since these mesoregions are the largest cattle producers in Pará and have most of their territory deforested for pasture implementation

Livestock rabies in Pará state, Brazil: a descriptive study (2004 to 2013)

ABSTRACT: Rabies is an important zoonosis to public health associated with lethal encephalitis and economic losses. Analysis of its spatial distribution is a meaningful tool in understanding its dispersion, which may contribute to the control and prophylaxis of the disease. This study analyzed the spatial-temporal distribution of rabies outbreaks in livestock in Pará state, Brazil, from 2004 to 2013. We used records of neurological syndromes obtained from the state’s livestock authority (Adepará). The analysis recorded 711 neurological syndromes reports in livestock, of which 32.8% were positive for rabies. In 8% of the neurological syndromes (n=57) was not possible to perform the analysis because of bad-packaging conditions of the samples sent. Outbreaks involved at least 1,179 animals and cattle were the most affected animal species (76.8%). The numbers of reported neurological syndromes and of rabies outbreak shad strong positive correlation and exhibited decreasing linear trend. Spatially, most outbreaks occurred in two mesoregions in Pará (Northeast and Southeast). One of the justifications for this spatial distribution may be related with the distribution of the animals in the state, since these mesoregions are the largest cattle producers in Pará and have most of their territory deforested for pasture implementation

Trabalho completo: acesso restrito, p.1100–1103The present work describes the development of a fast and robust sequential injection fluorimetric procedure for the determination of Sn in juices of canned fruits. The developed automatic methodology is based on the complexation of Sn with 8-hydroxyquinoline-5-sulfonic acid (HQSA) to form a fluorimetric product (λexc = 354 nm; λem = 510 nm). The influence of dimethylsulfoxide (DMSO) and cetylpyridinium bromide (CPB) on the sensitivity of the fluorimetric determination was evaluated. Linear calibration plots were obtained for Sn concentrations between 1 and 10 mg L−1, with a detection limit of 0.38 mg L−1. In each analytical cycle 0.006 mg of HQSA and 0.47 mg of CPB were consumed and 1.5 mL of effluent was generated. The developed methodology was applied to the determination of Sn in juices of canned fruits and the results complied with those furnished by an electrothermal atomic absorption spectrometry comparison procedure, with relative deviations lower than 5.2%. The automatic procedure exhibited good precision (R.S.D. < 1.4%) and the sampling rate was about 70 determinations per hour

Qualidade fisiológica de sementes de pitangueira submetidas a diferentes procedimentos de secagem e substratos - Parte 2 Physiological quality of surinam cherry seeds submitted to different procedures of drying and substrates - Part 2

Conduziu-se este trabalho com o objetivo de determinar o procedimento de secagem e substratos ideais para avaliar a visibilidade e o vigor das sementes e crescimento inicial das plântulas de pitangueira (Eugenia uniflora L.). Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial 2 x 4 (2 procedimentos de secagem: à sombra e ao sol; 4 substratos: Areia, vermiculita, pó-de-coco e papel toalha), com quatro repetições de 25 sementes cada uma e se avaliaram os seguintes parâmetros: tempo médio de germinação, comprimento da raiz e do epicótilo e massa seca da plântula. O experimento foi conduzido em germinador tipo BOD, regulado a temperatura constante de 25 ºC e regime de luz contínua. O procedimento de secagem à sombra e o substrato vermiculita podem ser recomendados para testar o vigor dessa espécie.<br>This study had as its objective the determination of ideal procedure of drying and the substrate to evaluate the vigour and the initial growth of surinam cherry seedlings (Eugenia uniflora L.). The used design was entirely randomized in factorial scheme 2 x 4 (2 procedures of drying: shade and sun; 4 substrates: sand, vermiculite, coconut fiber and paper towels) with four replications of 25 seeds each. The following parameters were also analyzed: average time of germination, length of primary root and epicotyl and dry weight of the seedling. The experiment was conducted in BOD regulated at constant temperature of 25 ºC and regime of continuous light. The shade method of drying and the vermiculite substrate can be recommended to test the vigour of this specie
