The pathogenesis of encephalitis associated with the respiratory pathogen Myco-plasma pneumoniae is not well understood. A direct infection of the central nervous system (CNS) and an immune-mediated process have been discussed [1]. Recent observations suggest that intrathecally detectable antibodies against the bacterium , which can serve to establish the(More)
We have identified a rat cytomegalovirus (RCMV) gene that encodes a G-protein-coupled receptor (GCR) homolog. This gene (R33) belongs to a family that includes the human cytomegalovirus UL33 gene. R33 was found to be transcribed during the late phase of RCMV infection in rat embryo fibroblasts. Unlike the mRNAs from all the other members of the UL33 family(More)
BACKGROUND Persistent carriers have a higher risk of Staphylococcus aureus infections than noncarriers but a lower risk of bacteremia-related death. Here, the role played by anti-staphylococcal antibodies was studied. METHODS Serum samples from 15 persistent carriers and 19 noncarriers were analyzed for immunoglobulin (Ig) G, IgA, and IgM binding to 19 S.(More)
BACKGROUND Mycoplasma pneumoniae is thought to be a common cause of respiratory tract infections (RTIs) in children. The diagnosis of M. pneumoniae RTIs currently relies on serological methods and/or the detection of bacterial DNA in the upper respiratory tract (URT). It is conceivable, however, that these diagnostic methods also yield positive results if(More)
Cytomegalovirus (CMV) infections have been shown to dramatically affect solid organ transplant graft survival in both human and animal models. Recently, it was demonstrated that rat CMV (RCMV) infection accelerates the development of transplant vascular sclerosis (TVS) in both rat heart and small bowel graft transplants. However, the mechanisms involved in(More)
Epstein-Barr virus (EBV) infection is associated with many lymphoproliferative diseases, such as infectious mononucleosis and Burkitt's lymphoma. Consequently, EBV is one of the most extensively studied herpesviruses. Surprisingly, a putative G protein-coupled receptor (GPCR) gene of EBV, BILF1, has hitherto escaped attention, yet BILF1-like genes are(More)
The rat cytomegalovirus (RCMV) R33 gene is conserved among all betaherpesviruses and encodes a protein (pR33) that shows sequence similarity with chemokine-binding G protein-coupled receptors (GPCRs). Previously, the physiological significance of the R33 gene was demonstrated by the finding that an RCMV strain with R33 deleted is severely attenuated in vivo(More)
The rat cytomegalovirus (RCMV) R33 and R78 genes are conserved within members of the subfamily Betaherpesvirinae and encode proteins (pR33 and pR78, respectively) that show sequence similarity with G protein-coupled receptors. Previously, the biological relevance of these genes was demonstrated by the finding that R33- and R78-deleted RCMV strains are(More)
BACKGROUND Mycoplasma pneumoniae has previously been characterized as a micro-organism that is genetically highly stable. In spite of this genetic stability, homologous DNA recombination has been hypothesized to lie at the basis of antigenic variation of the major surface protein, P1, of M. pneumoniae. In order to identify the proteins that may be involved(More)
In all herpesviruses a block of genes is present which is composed of the genes encoding DNA polymerase, glycoprotein B (gB), ICP18.5 and major DNA-binding protein (MDBP). Here we report the cloning and sequencing of this gene block from rat cytomegalovirus (RCMV). The gene block spans 13.3 kbp and contains the four genes in the order pol, gB, ICP18.5 and(More)
