An analysis of the 1978 African swine fever outbreak in Brazil and its eradication

Abstract: The aim of this paper is to evaluate the African swine fever (ASF) outbreak that began in 1978 in Paracambi municipality, Rio de Janeiro State, Brazil, and the steps taken by the Brazilian authorities to eradicate the disease. The presence of ASF in the country was confirmed by isolating the virus, and its pathogenicity was certified by the laboratory of the Plum Island Disease Center, New York, United States. Even before the laboratory results became available, the Brazilian Agriculture Ministry declared an Animal Health Emergency, in which the official Veterinary Services adopted rapid control measures to restrain and eradicate the disease. These control measures contributed to the reorganisation of the national swine industry and stimulated the use of high-technology production techniques, as well as an improvement in herd health consciousness. All this contributed to Brazil becoming the largest meat exporter in the world.

Incidence and abundance of mycotoxins in maize in Rio Grande do sul, Brazil

Abstract: The levels of aflatoxins B1, B2, G1, and G2, ochratoxin A, zearalenone and sterigmatocystin were determined by thin-layer chromatography in 36 samples of stored maize in the state of Rio Grande do Sul; the samples were obtained from May to September 1988, 23 samples were from silos and 13 samples were collected directly from farms. In 34.8% of the samples from silos aflatoxin B1+G1 was detected in concentrations that varied from 12 to 906 micrograms/kg. In 13% of the samples from silos aflatoxin B2 was detected in concentrations that varied from 48 to 180 micrograms/kg. In 9% of the samples from silos aflatoxin G2 was detected in concentrations that varied from 6 to 11 micrograms/kg. In 23% of the samples collected directly from farms aflatoxin B1+G1 was detected in concentrations that varied from 10 to 14 micrograms/kg. Ochratoxin A, zearalenone and sterigmatocystin were not detected at any time.

Comparative evaluation of three commercially available complement fixation test antigens for the diagnosis of glanders

Abstract: The sensitivity and specificity of three commercially available complement fixation test (CFT) antigens from c.c.pro (c.c.pro), Central Veterinary Institute of Wageningen UR (CIDC) and the United States Department of Agriculture (USDA) were comparatively evaluated by testing 410 sera collected from glanders-endemic and non-endemic areas (200 true-negative randomly collected sera and 210 sera collected from experimentally immunised animals (12 rabbits, 19 horses), clinically positive (135) and culture-positive (44) horses, donkeys and mules). Immunoblotting (IB) was used as the gold standard test. Highest sensitivity was shown for the CIDC antigen (100 per cent) followed by the c.c.pro antigen (99.39 per cent). However, the USDA antigen showed substantially less (p<0.05) sensitivity (62.19 per cent). Highest specificity was found for the USDA antigen (100 per cent) followed by the CIDC (97.5 per cent) and c.c.pro antigen (96.5 per cent). Positive and negative predictive values (assumed glanders prevalence of <0.1 per cent) for each antigen were calculated to be 95.88 and 99.48 (c.c.pro), 97.04 and 100 (CIDC), 100 and 76.33 per cent (USDA), respectively. Almost perfect agreement (0.96) was found between CFT using either c.c.pro or CIDC and IB.

Avaliação de genótipos de bananeira sob irrigação

Abstract: Como alternativa de genotipos de bananeira para o semi-arido irrigado do norte de Minas Gerais, foram avaliados quatro ciclos de producao da variedade Caipira (AAA) e dos hibridos SH3640 (AAAB), FHIA 1 (AAAB), FHIA 18 (AAAB) e Pioneira (AAAB), alem de tres ciclos da variedade Prata-Ana (AAB), no espacamento 3 m x 2,7 m, em delineamento inteiramente casualizado, com 25 repeticoes de uma planta. Foram avaliados caracteres da planta e da producao, levando a conclusao de que os genotipos 'SH3640', 'FHIA 1' e 'FHIA 18' sao mais produtivos que a 'Pioneira', 'Caipira' e 'Prata-Ana'. A 'Pioneira' apresentou maior crescimento inicial, porem, na floracao, a maior altura foi apresentada pela 'Caipira', sendo que todos os genotipos se igualaram no quarto ciclo. A 'Caipira' apresentou maior numero de frutos e a 'SH3640' apresentou cachos mais pesados e frutos maiores.
