In order to induce a non-lethal infection restricted to central aminergic neurons projecting to the olfactory bulbs a series of temperature sensitive (ts) and G-protein monoclonal antibody escape mutants of vesicular stomatitis virus (VSV) were instilled into the nasal cavity of mice. In three-week (wk)-old NMRI mice four monoclonal antibody escape mutants(More)
Intracerebral injection of hamster neurotropic (HNT) measles virus in weanling Balb/C mice leads to an encephalitis, which is characterized by glial activation, behavioral seizures, selective neurodegeneration, and, after approximately 7 days, death. To provide a better understanding of the underlying molecular pathology, we studied seizure evolution by(More)
Elevated numbers of B cells--plasma cells secreting antibodies to measles and mumps virus, and to myelin associated glycoprotein (MAG), one of several putative myelin autoantigens--have previously been reported in cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS), while it is unknown if corresponding T cell reactivities occur. We have(More)
In a pandemic setting, surveillance is essential to monitor the spread of the disease and assess its impact. Appropriate mitigation and healthcare preparedness strategies depend on fast and accurate epidemic surveillance data. During the 2009 influenza A(H1N1) pandemic, rapid improvements in influenza surveillance were made in Iceland. Here, we describe the(More)
Antigenic characteristics of nine mumps virus strains were determined by immunofluorescence and radioimmunoprecipitation assay (RIPA) using a collection of 44 monoclonal antibodies. These antibodies were directed against five different structural components of mumps virus, the haemagglutinin-neuraminidase (HN), fusion (F), matrix (M), phospho- (P) and(More)
Variants of hepatitis C virus (HCV) from a single infected blood donor and 13 viraemic recipients who were traced were examined by sequencing and cloning to determine the extent of virus diversity in hypervariable region 1. Serum-derived viral isolates were studied from the donor when his HCV infection was discovered in 1993, in his recipients that year(More)
BACKGROUND Characteristics of patients with community-acquired pneumonia (CAP) due to pandemic influenza A 2009 (H1N1) have been inadequately compared to CAP caused by other respiratory pathogens. The performance of prediction rules for CAP during an epidemic with a new infectious agent are unknown. METHODS Prospective, population-based study from(More)
In order to examine the status of quinolinic acid (QUIN) metabolism in a model of delayed excitotoxic neurodegeneration, the de novo production of QUIN from 3-hydroxyanthranilic acid was assessed in brain homogenates and brain slices of mice injected with hamster neurotropic measles virus. In the hippocampus, which presents exclusive nerve cell loss in this(More)
Functional properties of cultured mouse dorsal root ganglion cells infected with paramyxoviruses have been studied using intracellular recording techniques. Mumps virus, which causes a persistent non-lytic infection, and Sendai virus, which causes an infection that leads to cell lysis after about a week were used. In the early phase of the infection (24-48(More)
