We report a stem cell transplant recipient who developed human herpesvirus 6 encephalitis. Human herpesvirus 6 load indicated massive intrathecal viral replication. Administration of cidofovir followed by foscarnet was associated with total clearance of human herpesvirus 6 infection. Cidofovir and foscarnet combination therapy may be beneficial for reducing mortality of (neutropenic) stem cell ...

The genome of a herpesvirus highly pathogenic to rabbits, leporid herpesvirus 4 (LHV-4), was analyzed using high-throughput DNA sequencing technology and primer walking. The assembled DNA sequences were further verified by restriction endonuclease digestion and Southern blot analyses. The total length of the LHV-4 genome was determined to be about 124 kb. Genes encoded in the LHV-4 genome are m...

BACKGROUND Acute and recurrent acute urticaria are often associated with multiple factors including infections and recent data suggest a role for herpesviruses. OBJECTIVE To test the null hypothesis, that is, there is no association of herpesvirus infections with urticaria. METHODS Thirty-seven patients between one month and 15 years of age were age matched to 37 controls who were healthy o...

In this study, we attempted to express twelve glycoproteins of equine herpesvirus-1 (EHV-1) in 293T cells and to characterize these using monoclonal antibodies (MAbs) and horse sera against EHV-1. Expression of glycoprotein B (gB), gC, gD, gG, gI and gp2 was recognized by immunoblot analysis using horse sera, but that of gE, gH, gK, gL, gM and gN was not. Four MAbs recognized gB, four recognize...

After cell infection with the equine herpesvirus 1 (EHV-1), the termini of the linear double-stranded DNA genome fuse to form circular forms. To investigate the mechanisms in the generation and cleavage of such replicative-form DNAs, the genomic termini, the fusion of termini from replicative-form molecules, and the junction between the short and long genome segments have been analyzed by restr...

We have sequenced a 5.4 kb region of the genome from the avian herpesvirus infectious laryngotracheitis virus (ILTV) and identified genes homologous to the thymidine kinase (TK) gene, the capsid p40 gene of herpes simplex virus type 1 (HSV-1), a gene encoding a protein antigenic in Epstein-Barr virus infections plus one other highly conserved gene encoding a protein implicated in cell fusion in...

This paper reports the investigation of risk factors for bovine herpesvirus-1-seropositivity, based on a cluster-sample survey of the Belgian cattle population. This serosurvey was carried out in 1998 in 309 randomly selected unvaccinated herds of all types (dairy, mixed and beef) were all bovids (N = 11,284) were sampled. Older and male cattle had higher seroprevalence. Origin (homebred or pur...

The discovery of lymphoid B-Iymphotropic herpesvirus-producing cell lines from M. arctoides peripheral lymphocytes (MAL-l) producing their own lymphotropic virus HVMA was reported earlier [1]. Subsequently, two more M. arctoides virus-producing lymphoid cell lines (MAL-2, MAL-3) were discovered in our laboratory. The cells of some baboon lymphoid cultures, parallel with B-Iymphotropic herpesvir...

We have cloned and characterized the entire DNA polymerase gene and flanking regions from Kaposi's sarcoma-associated herpesvirus (KSHV) and two closely related macaque homologs of KSHV, retroperitoneal fibromatosis-associated herpesvirus-Macaca nemestrina (RFHVMn) and -Macaca mulatta (RFHVMm). We have also identified and partially characterized the corresponding genomic region of another KSHV-...
