| Toxicity risks of agricultural pesticides to fishes are pivotal. Currently, many questions remain unsolved regarding to the toxicity of commonly used pesticides to silver catfish (Rhamdia quelen), a South American catfish. The present studies have been designed to investigate the acute toxicity and the lethal concentration (LC50) of four herbicides, two fungicides and two insecticides to silver catfish fingerlings. All experiments were carried out in triplicates, in a static bioassay system, using commercially available pesticides. The data was analyzed through the Trimmed Spearman-Karber method available from the Environmental Protection Agency. The 96hLC50 and 95% lower and upper confidence limits, respectively, for the following pesticides were... |

| Abstract Three dog shelters in Rio Grande do Sul were investigated for associations between the occurrence of respiratory viruses and shelter environmental conditions. Nasal secretions randomly collected during the cold season were tested via PCR, and this data collection was followed by nucleotide sequencing of the amplicons. In shelter #1 (poor sanitary and nutritional conditions, high animal density and constant contact between dogs), 78% (58/74) of the nasal samples were positive, 35% (26/74) of which were in single infections and 44% (32/74) of which were in coinfections. Shelters #2 and #3 had satisfactory sanitary and nutritional conditions, outdoors exercise areas (#2) and animal clustering by groups (#3). In shelter #2, 9% (3/35) of the samples... |

| Este trabalho avaliou a imunogenicidade de vacinas para os herpesvírus bovino 1 e 5 (BoHV-1, BoHV-5) e vírus da diarreia viral bovina 1 e 2 (BVDV-1, BVDV-2), disponíveis no mercado brasileiro. Para isso, novilhos de raças de corte foram alocados em grupos de 10-12 animais e vacinados duas vezes, com intervalo de 30 dias, com cada uma das oito vacinas disponíveis. Amostras de soro coletadas 30 dias após a segunda dose foram submetidas ao teste de virusneutralização (VNT), frente a cepas de BoHV-1, BoHV-5, BVDV-1 e BVDV-2. Com exceção de duas vacinas que induziram soroconversão em 8/10 e 9/10 dos animais, as demais induziram anticorpos neutralizantes contra o BoHV-1 em todos os animais vacinados (títulos médios geométricos [GMTs] entre 1,7 e 4,8). Quatro... |
