Hematological and cerebrospinal fluid changes in cattle naturally and experimentally infected with the bovine herpesvirus 5 BABT
Lisbôa,Júlio Augusto Naylor; Isernhagen,Allan Jürgen; Borges,Alexandre Secorun; Amorim,Rogério Martins; Balarin,Mara Regina Stipp; Lunardi,Michele; Alfieri,Amauri Alcindo.
Bovine herpesvirus 5 (BoHV-5) meningoencephalitis is one of the main causes of mortality by encephalopathy in Brazilian cattle herds. However, the neurological signs observed are common to several encephalopathies and do not contribute decisively to a diagnosis. In order to verify hematological and cerebrospinal fluid (CSF) changes, blood and CSF samples from naturally and experimentally infected bovines were evaluated. In natural cases (n=17), the samples were collected only once, and in experimental cases (n=7), the samples were sequentially obtained throughout disease progression. While routine methods were used to examine the samples, BoHV-5 infection was confirmed by a PCR assay. Blood analyses did not reveal any consistent hematological alterations...

Herpèsvirus infectant les bivalves marins : détection, génome et transmission ArchiMer
Arzul, Isabelle.
Since 1991, high mortality rates of larvae and juveniles of different bivalve mollusc species associated with herpesvirus infections have been reported in different countries. The aim of this study was to determine if more than one helpesvirus species was responsible for these infections or just one species exhibiting polymorphism. The investigations concentrated on the analysis of the virus genome, studies of virus transmission in different mollusc species and on the potential role of bivalve adults in the occurrence of infections. The analysis of various target sequences within the virus genome present in infected larvae samples demonstrated the presence of polymorphism. More notably a variant of the virus was identified and the variation appears...
