Can porcine herpesviruses infect humans? Are they linked to human diseases of the immune system? Are HHV-6, HHV-7 and HHV-8 viruses that came from pigs? Would pigs make a good model for the study of HHV-6, HHV-7 and HHV-8 infections? What are porcine herpesviruses doing to overall swine health across the planet?Unknownnoreply@blogger.comBlogger5125tag:blogger.com,1999:blog-9161962095022602550.post-70081422081591154852015-04-01T05:56:00.002-07:002015-04-01T05:56:44.022-07:00Porcine lymphotropic herpesviruses 1 and 2<a href="http://zoologix.com/avian/Datasheets/PorcineLymphotropicHerpesvirus.html">http://zoologix.com/avian/Datasheets/PorcineLymphotropicHerpesvirus.html</a>Unknownnoreply@blogger.com5tag:blogger.com,1999:blog-9161962095022602550.post-81477105721383595042015-04-01T05:54:00.002-07:002015-04-01T05:54:25.784-07:00Early weaning of piglets fails to exclude porcine lymphotropic herpesvirus.<a href="http://www.ncbi.nlm.nih.gov/pubmed/15598274">http://www.ncbi.nlm.nih.gov/pubmed/15598274</a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-9161962095022602550.post-53432468606293211002015-04-01T05:53:00.002-07:002015-04-01T05:53:47.255-07:00Infection of porcine cells with human herpesviruses.<a href="http://www.ncbi.nlm.nih.gov/pubmed/20692426">http://www.ncbi.nlm.nih.gov/pubmed/20692426</a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-9161962095022602550.post-87307532289439488022015-04-01T05:52:00.001-07:002015-04-01T05:52:46.620-07:00Sequence Analysis of the Genome of Porcine Lymphotropic Herpesvirus 1 and Gene Expression during Posttransplant Lymphoproliferative Disease of Pigs<a href="http://www.sciencedirect.com/science/article/pii/S0042682202913905">http://www.sciencedirect.com/science/article/pii/S0042682202913905</a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-9161962095022602550.post-80215697935728236372015-04-01T05:44:00.001-07:002015-04-01T05:45:20.604-07:00Detection of two novel porcine herpesviruses with high similarity to gammaherpesviruses.<a href="http://vir.sgmjournals.org/content/80/4/971">http://vir.sgmjournals.org/content/80/4/971</a><br />

"Evidence for the existence of porcine gammaherpesviruses was obtained by
PCR and sequence analysis. Initially, samples of
peripheral blood mononuclear cells (PBMC), spleens,
lungs, kidneys and livers of pigs from Germany and Spain were tested
with
a PCR assay which targets conserved regions of the
herpesvirus DNA polymerase gene with degenerate and
deoxyinosine-substituted
primers. Amplicons of identical sequence were
obtained from one spleen and two PBMC samples. This sequence showed a
high percentage
of identity with the DNA polymerase genes of
herpesviruses of the oncogenic subfamily Gammaherpesvirinae. Alignment
of amino
acid sequences showed the highest identity values
with bovine gammaherpesviruses, namely alcelaphine herpesvirus type 1
(68%),
ovine herpesvirus type 2 (68%) and bovine
lymphotropic herpesvirus (67%). Comparison with pseudorabies virus and
porcine cytomegalovirus,
which are the only porcine herpesvirus species
presently known, showed values of only 41%. PCR analysis of PBMC (n =
39) and
spleen (n = 19) samples from German pigs, using
primers specific for the novel sequence, revealed a prevalence of 87 and
95%,
respectively. In this analysis, three out of eight
spleen samples from Spanish pigs were also positive. Subsequent
sequencing
of the amplicons revealed the presence of two
closely related gammaherpesvirus sequences, differing from each other by
8%
at the amino acid level. The putative novel porcine
herpesviruses, from which these sequences originated, were tentatively
designated porcine lymphotropic herpesvirus type 1
and type 2 (PLHV-1 and PLHV-2). When using pig organs for
xenotransplantation,
the presence of these viruses has to be considered"
