| Os vírus da anemia infecciosa eqüina (VAIE), da arterite viral dos eqüinos (VAVE) e do aborto viral eqüino (Herpesvírus eqüino tipo 1, HVE-1) são agentes causadores de enfermidades nos eqüídeos que podem causar graves prejuízos econômicos. O objetivo do presente trabalho foi estimar a soroprevalência de anticorpos contra os vírus VAIE, VAVE e HVE-1, utilizando como unidades de análise os eqüídeos e as propriedades rurais do tipo familiar do município de Uruará, PA. Os anticorpos contra o VAIE foram pesquisados pela prova de imunodifusão em gel de ágar e os anticorpos contra o VAVE e o HVE-1 pela prova de soroneutralização. O tamanho da amostra foi estimado a partir de um total de 2069 propriedades, caracterizadas por agricultura familiar e ausência de... |

| Hamsters orally inoculated with ERA and PV strains of rabies virus were sacrificed at 24, 48, 72 hours, 21 and 30 days after inoculation. Brain fragments were examined by Fluorescent Antibody test (FAT) and heminested PCR (hn-PCR). Fragments from stomach, blood, heart, and lung were examined only by hn-PCR. Sera of other hamsters, similarly inoculated, obtained at 30th day after inoculation were submitted to mouse neutralization test. The hamsters were challenged intracerebrally with CVS strain with 10(2.7)mouse LD50/0.03mL, 45 days after inoculation. Brains examined by FAT were negative. The hn-PCR detected the presence of rabies virus RNA in the lung of one animal inoculated with ERA, and in the brain, stomach, blood, and lung of PV-infected animals. The... |

| The aim of the present experiment was to standardize a nested polymerase chain reaction (nPCR) for the detection of Toxoplasma gondii in tissues of experimentally infected pigs and to compare the performance of nPCR with the standard isolation technique, the bioassay in mice. Comparison between the two methods was done testing eight 4 month-old pigs orally inoculated with 5 x 10(4) oocysts of Toxoplasma gondii (AS-28 strain) and three non-infected pigs at the same age, kept as control. All animals were euthanatized 47 days after infection and samples of brain, heart, tongue and retina were collected from each animal for analysis by nPCR and bioassay in mice. By using the bioassay, Toxoplasma gondii was detected in 4 infected pigs, being two in the retina,... |

| The genomic DNA of thirty strains of Aujeszky's disease virus (ADV) isolated in the South and Southeast regions of Brazil from 1982 to 1996 were characterized by restriction endonuclease analysis with BamHI. Twenty seven strains were isolated from pigs, 1 from cattle, 1 from cat and 1 from dog. Using a systematization previously described, the 30 ADV strains could be classified as genomic types I (n = 2) and II (n = 28). Genomic type III was not observed. In this first study of genomic type characterization of brazilian ADV strains, we could demonstrate the occurence in Brazil of the genomic types I and II, with a large predominance of genomic type II. |
