Herpesviruses have mainly co-evolved with their hosts for millions of years. However, bovine herpesvirus 1 (BoHV1) and related ruminant alphaherpesviruses have been reported to cross the species barrier. Bubaline herpesvirus 1 (BuHV1) is an alphaherpesvirus closely related to BoHV1 and BoHV5. According to the serological cross-relationships between ruminant alphaherpesviruses, several surveys have studied the occurrence of BoHV1-related virus infection in wild and domestic ruminant species. Recent studies in Argentina showed an increase in serological prevalence against BoHV1 related viruses in water buffaloes (Bubalus bubalis) population. The aim of this study was to investigate the presence of related ruminant alphaherpesvirus in the Argentinean water buffalo population. BuHV1 was successfully isolated from 5 out of 225 buffaloes analyzed. One isolate was obtained from nasal secretions, and the others were from vaginal swabs. The buffaloes belonged to four different farms located in northeastern Argentina. The isolates were characterized as alphaherpesvirus by direct immunofluorescence using FITC-anti-BoHV1 IgG. Restriction analysis performed with BamHI and BstEII on the complete genome showed differences between the isolates and those from BoHV1 and BoHV5 subtypes. Phylogenetic analysis on both UL27 and US6 showed similarity in tree topology. While three of the isolates grouped together with sequences of BoHV5, two other isolates clustered separately. Genetic analysis of eight concatenated sequences from all isolates and references strains showed high nucleotide sequence identity between BuHV1 and BoHV5. While three of the isolates clustered together with the BoHV5 reference strain, the last two isolates were closely related to an Australian BuHV1 strain. To our knowledge, this is the first report on the isolation and molecular characterization of BuHV1 in South America. Phylogenetic analysis suggested that two different BuHV1 lineages circulate in the Argentinean water buffalo population. [less ▲]

By screening 104 faecal samples from asymptomatic calves in Italy, bovine norovirus RNA was detected with a prevalence rate of 10.5 % (11/104). A continuous sequence spanning the RdRp region and the 50 end of the capsid gene was generated for 7 of the 11 strains. Upon phylogenetic analysis, five strains were grouped with GIII.2 Newbury2-like viruses, and one strain was grouped with GIII.1 Jena-like noroviruses. Interestingly, one strain (80TE/IT) was genetically related to the GIII.1/Jena/80/De in the RdRp but resembled the GIII.2/Newbury2/76/UK in the capsid gene, suggesting a recombination event occurring in the ORF1/ORF2 junction region.

The taxonomy of herpesviruses has been updated by the International Committee on Taxonomy of Viruses (ICTV). The former family Herpesviridae has been split into three families, which have been incorporated into the new order Herpesvirales. The revised family Herpesviridae retains the mammal, bird and reptile viruses, the new family Alloherpesviridae incorporates the fish and frog viruses, and the new family Malacoherpesviridae contains a bivalve virus. Three new genera have been created in the family Herpesviridae, namely Proboscivirus in the subfamily Betaherpesvirinae and Macavirus and Percavirus in the subfamily Gammaherpesvirinae. These genera have been formed by the transfer of species from established genera and the erection of new species, and other new species have been added to some of the established genera. In addition, the names of some nonhuman primate virus species have been changed. The family Alloherpesviridae has been populated by transfer of the genus Ictalurivirus and addition of the new species Cyprinid herpesvirus 3. The family Malacoherpesviridae incorporates the new genus Ostreavirus containing the new species Ostreid herpesvirus 1. [less ▲]

Porcine noroviruses and sapoviruses belong to the family Caliciviridae and are rarely reported in European countries. In this study, swine stools from a region representative of northern Europe were screened for these viruses by RT-PCR. Both porcine noroviruses and sapoviruses were detected, showing their circulation in this region. The porcine norovirus strains were genetically related to genotype 19 strains in the genogroup II of the genus Norovirus. The porcine sapovirus strains were genetically related to the porcine enteric calicivirus Cowden reference strain and to newly described porcine strains in the genus Sapovirus. [less ▲]

This study was conducted to compare the pathogenesis of acute and latent infections with closely related bovine herpesvirus types 1 (BHV-1) and 5 (BHV-5) in their natural host. Two groups of eight calves were inoculated intranasally with BHV-1 or BHV-5. Although BHV-1 and BHV-5 similarly replicate in the nasal mucosa after inoculation, both viruses differ markedly in their ability to cause disease, BHV-5 being responsible of some fatal encephalitis while BHV-1 inducing rhinotracheitis. Virus isolation and immunohistochemistry demonstrated that BHV-5 replicates extensively in neurons of the central nervous system (CNS) and in respiratory cells of lungs, tracheal and nasal mucosae. Invasion of the CNS likely occurs through the trigeminal and olfactory pathways. Both groups developed cross-neutralising antibodies during this experiment suggesting partial clinical cross-protection afforded by the two infections. Three months after primary infection, experimental reactivation showed that BHV-5 was able to establish latency in the trigeminal ganglia but also the CNS of surviving calves. Moreover, laboratory findings suggested that BHV-5 could also persist in the tracheal and nasal mucosae. These results indicate that, after primary infection, BHV-1 and BHV-5 displayed similar biological features and consequently need to be considered together for the control of BHV-1 infection.

The nucleotide sequence of a 10.5 kb region (map position 0.332 to 0.410) of bovine herpesvirus type 1 (BHV-1) was determined. This region contained three open reading frames (ORFs) homologous to herpes simplex virus DNA polymerase catalytic subunit (DNApol, UL30), major DNA-binding protein (MDBP, UL29) and ICP18.5 assembly protein (ICP18.5, UL28). The BHV-1 DNApol. MDBP and ICP18.5 ORFs were 1246, 1203 and 826 amino acids long with a calculated molecular mass of 134.2 kDa, 124.4 kDa and 86.9 kDa, respectively. They showed a high homology with alphaherpesvirus homologs despite large differences in the G + C content of the UL30-UL28 segment ranging from 44.4% for varicella zoster virus to 71.5% for BHV-1. Particularly well conserved among Alphaherpesvirinae are the putative functional domains of the DNApol and MDBP proteins which are discussed. Phylogenetic analysis revealed that BHV-1 clustered in the Varicellovirus genus with the animal D-type viruses. In this group, the BHV-1 position was shown to vary according to the investigated genes. Indeed, pseudorabies virus clustered with BHV-1 in the DNApol tree but with equine herpesvirus 1 in the ICP18.5 tree. [less ▲]

The nucleotide sequence of a 6 kb fragment encoding the main late proteins (p14, p38 and p24) of actinophage VWB was obtained. Sequence comparison of the encoded proteins with those filed in databases indicated that the phage VWB main late proteins were all novel. A search for special motifs revealed that p14 (13.3 kDa) has a P-loop sequence commonly found in ATP- and GTP-binding proteins. This observation might indicate that p14 is important for ATP-driven DNA translocation during encapsidation of VWB phage DNA into the phage head. Furthermore, the polypeptide ORF2 (26.9 kDa) has an unusual primary structure consisting of 3 stretches of acidic amino acid residues and a glycine/arginine rich C-terminal end. From comparison with other proteins including the bacteriophage T4 prohead core component and from the data of special motif analysis the ORF2 gene product is probably involved in prohead core formation.

Three glycoproteins of bovine herpesvirus-1 (BHV-1) other than glycoproteins gI, gIII, and gIV were identified by monoclonal antibody (MAb) analyses. Monoclonal antibodies were obtained by immunization of mice with either BHV-1 envelope or virus infected cells, from which the glycoproteins gI, gIII, and gIV were removed by immunoaffinity. In the latter immunization procedure mice were tolerized either against normal cellular antigens with or without glycoproteins gI, gIII, gIV, and nucleocapsid. From 154 anti-BHV-1 hybridomas isolated, 39 MAbs precipitated a 108K glycoprotein. Two other glycoproteins of respectively 42K and 93K were precipitated each by one MAb. These three glycoproteins were detected in infected cell lysate. Nine anti-108K glycoprotein MAbs neutralized BHV-1 infectivity and three non-neutralizing MAbs were able to reduce plaque development when virus was grown in the presence of these MAbs. It is therefore suggested that this glycoprotein is involved in viral entry into the cell and in cell-to-cell spread of the virus. [less ▲]

The location and nucleotide sequence of the bovine herpesvirus type 4 (BHV-4) thymidine kinase (TK) gene was determined. The coding region of the TK gene is 1335 nucleotides long and corresponds to a polypeptide of 445 amino acids. Comparison of TK amino acid sequences of BHV-4 and 16 herpesvirus TKs reveals a greater homology to those of the gammaherpesviruses EBV and specially HVS, than to those of alphaherpesviruses. The open reading frames detected in the vicinity of TK gene were homologous to the corresponding ones in other herpesviruses. [less ▲]

Twenty-eight Belgian field isolates of bovine herpesvirus 4 (BHV-4) coming from a variety of clinical diseases have been studied by restriction analysis and Southern blot hybridization. The unique central part of the genome was very well conserved among strains; only one variation in a restriction site was detected in 3 isolates which contain an additional EcoRI site also present in the LVR 140 strain; three regions in the unique part of the genome varied in size, one of these was highly variable. The polyrepetitive fragments (prDNAs) situated in tandem at both genomic ends were also variable in size; most of the isolates exhibited prDNA units of one size (major prDNA) and some of them also contained prDNA units having a different size and present in a lower amount (minor prDNA) than the major prDNA. Other isolates possessed two major prDNAs of different sizes which were both present in the same genome. The left junction fragment between the unique and the repeated sequences was also highly variable. No relationship could be established between the restriction pattern and the origin of the isolates; patterns of isolates coming from the same herd were similar except in one case. This study provides a view of the genome variability existing between BHV-4 field isolates. [less ▲]

A cDNA library was constructed with poly(A)+-mRNAs from NDV-Italien infected BHK-21 cells. A clone, that hybridized to the F gene mRNA, was sequenced. A long open reading frame encodes for a protein of 553 amino acids, with a calculated molecular weight of 59,153, consisting of twelve cysteine residues and six potential glycosylation sites. The protein sequence contains a hydrophobic region at the N-terminus of F1 and a presumptive long transmembrane fragment near the C-terminus. Comparison of the F proteins from NDV strains Italien and Australia-Victoria shows that the sequences are very similar, with conservation of most cysteine residues and of the potential glycosylation sites. The F coding sequence was inserted into the genome of vaccinia virus under the control of vaccinia P7.5 transcriptional regulatory sequences. Expression of F protein was demonstrated by indirect immunofluorescence with five anti-F monoclonal antibodies known to react with conformational epitopes. [less ▲]
