| This article reports on the identification of a group 2 coronavirus (BatCoV DR/2007) in a Desmodus rotundus vampire bat in Brazil. Phylogenetic analysis of ORF1b revealed that BatCoV DR/2007 originates from a unique lineage in the archetypical group 2 coronaviruses, as described for bat species elsewhere with putative importance in Public Health. |

| Rapid diagnosis of rabies in suspected human cases influences post-exposure prophylaxis for potential contacts of the patient and ensures appropriate patient management. Apart from the central nervous system (CNS), rabies virus (RABV) is usually present in small sensory nerves adjacent to hair follicles of infected humans. We used an RT-PCR, with primers targeted to the 3' terminal portion of the nucleoprotein gene (N), to test neck-skin samples of nine patients who had rabies in order to validate a diagnostic method that could serve as an additional tool for rabies diagnosis, particularly in antemortem samples. Six of eight postmortem samples were found to be positive for rabies by RT-PCR, and one of two samples collected antemortem was positive with this... |

| A raiva é uma doença infecciosa do sistema nervoso central de mamíferos causada pelo vírus da raiva (RabV), geralmente, transmitido pela mordedura de animais infectados. No Brasil, os morcegos hematófagos Desmodus rotundus são as principais fontes de infecção do RabV para bovinos e equinos. Este artigo descreve uma investigação epidemiológica e molecular de surtos de raiva ocorridos na região central do Rio Grande do Sul, entre maio e agosto de 2012. Nesse período, 45 casos suspeitos de raiva foram relatados em 22 pequenos rebanhos, localizados dentro de um raio de 4,7km, no município de Pinhal Grande. Desses, 32 amostras foram submetidas para diagnóstico da raiva, sendo que o RabV e/ou antígenos virais foram identificados em 27 amostras. Em um segundo... |

| Rabies is a zoonotic disease that affects all mammals and leads to more than 55,000 human deaths every year, caused by rabies virus (RABV) (Mononegavirales: Rhabdoviridae: Lyssavirus). Currently, human rabies treatment is based on the Milwaukee Protocol which consists on the induction of coma and massive antiviral therapy. The aim of this study was to assess the decrease in the titer of rabies virus both in vitro and in vivo using short-interfering RNAs. To this end, three siRNAs were used with antisense strands complementary to rabies virus nucleoprotein (N) mRNA. BHK-21 cells monolayers were infected with 1000 to 0.1 TCID50 of PV and after 2 hours the cells were transfected with each of tree RNAs in separate using Lipofectamine-2000. All three siRNAs... |
