• Abstract

  Rabies is an ancient disease which is still present on all continents, except Antarctica. Different animals may play a role in rabies transmission and, in the Americas, the vampire bat Desmodus rotundus is one of the main reservoirs, being able to transmit the virus to susceptible individuals, mainly by biting. Although rabies is almost 100% lethal in susceptible hosts, different reports …

With regard to research, the PV candidate can collaborate on projects …

  Dissecting essential roles of chicken interferon stimulated genes in the pathobiology of poultry viruses, AV.BR

• Abstract

  To initiate successful virus replication cycle, viruses have to breach a cascade of host cellular responses. Among these barriers, innate immune responses are most potent and independent to nature of pathogens. The objectives of this work are to define the interactions of chicken interferon stimulated genes (chISGs) with diverse poultry viruses that are of economic importance both in Braz…

• Abstract

  Co-infections in poultry farming are common and occur mainly by the stocking density, facilitating the spread of horizontal transmission pathogens. The infectious bronchitis virus (IBV) and avian metapneumovirus (aMPV) are respiratory pathogens responsible for economic losses in the poultry industry. The worsening of clinical signs of these infections are related to the presence of other…

• Abstract

  Newcastle disease virus (NDV), also known as avian paramyxovirus serotype 1 (APMV-1), is a major economic concern for poultry producer world worldwide. Recently, analysis of the genome sizes and sequences of genes has revealed two distinct clades within APMV-1: class I and II. While class I isolates have been recovery from wild birds and samples from live bird markets; class II isolates h…

  Serological, molecular detection, and characterization of avian paramyxovirus type-1 (class I and class II) in wild birds, BP.MS

• Abstract

  The larg diversity of native species, synanthropic or not, and migratory birds, potentially hosts a wide variety of bacterial, fungal and viral agents, whose identity is virtually unknown and may be targets for deep scientific studies. Besides representing a wealth of biodiversity, scientific exploration and commercial potential, these agents may pose potential health risks. Thus, this st…
