Newcastle disease virus (NDV), also designated as Avian paramyxovirus type 1 (APMV-1), is the causative agent of a notifiable disease of poultry but it exhibits different pathogenicity dependent on the virus strain. The molecular basis for this variability is not fully understood. The efficiency of activation of the fusion protein (F) is determined by presence or absence of a polybasic amino ac...
Human metapneumovirus (hMPV) is a paramyxovirus that causes respiratory tract infections ranging from mild upper airway infection to severe pneumonia. Patients with haematological disease, especially haematopoietic stem cell transplantation (HSCT) recipients, are more likely to develop more severe infections. We describe three cases of hMPV infection in HSCT patients. The most reliable diagnost...
In the field of cell biology it is usual to characterize cellular components obtained after different separative procedures by enzyme markers characteristic for a particular cell constituent. In the field of virology such procedures are generally not in use for the characterization of virus preparations. More often the labeling of cell proteins is employed when a differentiation between virus-s...
Paramyxoviruses produce pleiomorphic particles containing variable amounts of genetic material that correlate with virion diameter by electron microscopy. However, the infectious nature of these particles is unknown, and functional genomes are indistinguishable from defective RNA. A quantitative approach to paramyxovirus packaging revealed a majority of infectious Newcastle disease viruses cont...
