Adenovirus (AdV), enterovirus (EV), genogroup A rotaviruses (GARV) and Torque teno virus (TTV) are non-enveloped viral agents excreted in feces and so may contaminate water bodies. In the present study, the molecular detection of these viruses was performed in samples of surface water collected from the Arroio Dilúvio, a waterstream that crosses the city of(More)
This paper describes the first detection of adenovirus in a Brazilian Desmodus rotundus bat, the common vampire bat. As part of a continuous rabies surveillance program, three bat specimens were captured in Southern Brazil. Total DNA was extracted from pooled organs and submitted to a nested PCR designed to amplify a 280 bp long portion of the DNA(More)
In the present study, cross-protection to bovine herpesvirus type 5 (BHV-5) induced by bovine herpesvirus type 1 (BHV-1) vaccination was examined following inoculation of rabbits and calves with a glycoprotein E (gE)-negative BHV-1 vaccine and subsequent challenge with BHV-5. Rabbits (n=5) and calves (n=8) were vaccinated [five rabbits intranasally (IN),(More)
Here we report the presence and expression levels of the vanC1 and vanC(2/3) genes in vancomycin-susceptible strains of Enterococcus faecalis. The vanC1 and vanC(2/3) genes were located in the plasmid DNA and on the chromosome, respectively. Specific mRNA of the vanC1 gene was detected in one of these strains. Additionally, analysis of the vanC gene(More)
Twelve Brazilian isolates and three reference strains of bovine herpesviruses (BHVs) were subjected to restriction endonuclease analysis (REA) and monoclonal antibody (MAb) analysis. Viral DNA was cleaved with BamHI, BstEII, EcoRI, HindIII and PstI. The monoclonal antibody panel allowed the differentiation between types 1 and 5 viruses, while REA with(More)
Bovine herpesvirus 1 (BoHV-1) and 5 (BoHV-5) are important pathogens of the respiratory and genital tract of cattle and may also affect the central nervous system and cause meningoencephalitis. Both virus types are estimated to be widely distributed in Southern Brazil. In the present study, BoHV-1 and/or BoHV-5 DNA were detected in bovine semen samples from(More)
INTRODUCTION Staphylococcal species are pathogens that are responsible for outbreaks of foodborne diseases. The aim of this study was to investigate the prevalence of enterotoxin-genes and the antimicrobial resistance profile in staphylococcus coagulase-negative (CoNS) and coagulasepositive (CoPS) isolates from black pudding in southern Brazil. METHODS(More)
Different types and subtypes of bovine herpesvirus 1 and 5 (BoHV-1 and BoHV-5) have been associated to different clinical conditions of cattle, in such a way that type/subtype differentiation has become an essential tool for understanding the pathogenesis and epidemiology of BoHV infections. In search for a genomic region that would allow a clear(More)
Based on small scale studies or on little sensitive serological tests, bovines in the south of the state of Rio Grande do Sul, Brazil, are known to be infected with either bovine herpesvirus 1 (BoHV-1) or 5 (BoHV-5). However, whether the prevalence of each of these viruses is high or low is currently still unknown. In order to determine the extent of BoHV(More)
