ABSTRACT
ABSTRACT Although the use of vaccines has controlled enteric diseases in dogs in many developed countries, vaccine coverage is still under optimal situation in Brazil. There is a large population of nonimmunized dogs and few studies about the identification of the viruses associated with diarrhea. To address this situation, stool samples from 325 dogs were analyzed by polymerase chain reaction for the detection of common enteric viruses such as Canine adenovirus (CAdV), Canine coronavirus (CCoV), Canine distemper virus (CDV), Canine rotavirus (CRV) and Carnivorous protoparvovirus 1 (canine parvovirus 2; CPV-2). At least one of these species was detected in 56.6% (184/325) of the samples. The viruses detected most frequently in either diarrheic or nondiarrheic dog feces were CPV-2 (54.3% of the positive samples), CDV (45.1%) and CCoV (30.4%), followed by CRV (8.2%) and CAdV (4.9%). Only one agent was detected in the majority of the positive samples (63%), but co-infections were present in 37% of the positive samples and mainly included CDV and CPV-2. The data presented herein can improve the clinical knowledge in regions with low vaccine coverage and highlight the need to improve the methods used to control these infectious diseases in domestic dogs.

The spread of enteric viruses of domestic animals and human beings to wild species can be facilitated by the resistance of these viruses on the environment and their ability to be transmitted by water and contaminated food. The health status of the populations of pampas foxes (

A history of nervous disturbances and moralities [25%] among young chickens 10-21 day of age as well as a temporary drop in egg production and hatchability [10%] in parent flock occurred in a large poultry farm at EL-Qassiem area, kingdom of Saudi Arabia. Detection, isolation and identification of avian encephalomyelitis [AE] virus was done using embryonated chicken eggs, immunoflourscence [IF] and Immunodiffusion [ID] tests. Serological investigations were carried out on infected sera from both parent flocks and broiler chicks using Enzyme-linked immunosorbant assay [ELISA]. Histopathological studies were carried out on samples from naturally infected chick brains as well as brains from inoculated hatched chicks

Foi observada mortalidade em nove leitöes de uma leitegada de dez em uma granja no Estado do Rio Grande do Sul, Brasil. A enfermidade se estendeu por um período de 15 dias, afetando animais em torno de 30 dias de idade, com morte súbita, sem prévios sinais clíncios evidentes. Leitöes de outras leitegadas permaneceram sadios. Material coletado de leitöes mortos pela doença permitiram o isolamento de um vírus, posteriormente caracterizado como Vírus da Encefalomiocardite (VEMC) por testes de índice de neutralizaçäo. Exames histopatológicos revelaram lesöes compatíveis com a enfermidade provocada pelo VEMC
