| 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... |

| ABSTRACT: Modern swine production employs a high degree of technology and is organized in various production stages, in which reproduction is one of the most significant. However, reproductive losses associated to fetal death are still high. Fetal losses, including fetal mummification, may occur at a rate below 1.5% in a sound herd. The causes of fetal death can be very diverse, and include various infectious agents. Therefore, investigating the causes of fetal losses is important in the decision-making process related to the control and prophylaxis of the herd. The goal of this study was to carry out a molecular survey, analyzing porcine circovirus 2 (PCV2), porcine parvovirus (PPV), and pathogenic Leptospira as potential agents related to fetal death in... |

| Feline calicivirus (FCV) and feline herpesvirus type 1 (FHV-1) are the two primary causes of upper respiratory tract disease in cats. The aim of this study was to demonstrate the distribution of FCV and FHV-1 among the feline population of several counties in Rio Grande do Sul State, Brazil. To this end, conjunctival and nasal swabs were collected from 302 cats from different locations, including households, breeding catteries, veterinary clinics, animal hospitals and experimental research facilities. The samples were collected between July 2006 to June 2009. The virus isolation was performed in CRFK cells and, subsequently, the identification was confirmed by PCR. FCV, FHV-1, or both were isolated from 55 cats from 28 different locations. FCV alone was... |

| 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... |
