Avian paramyxovirus (APMV) serotypes, other than APMV-1, are wide spread in wild bird populations and are occasionally found in poultry. Most of our research has focused on APMV-1 because it includes Newcastle disease virus (NDV), which causes a severe disease in poultry. However, very little research has been done to understand the host range, genetic diversity and pathogenicity of other APMV serotypes. Some of the other APMV serotypes are associated with mild respiratory disease and decreased egg production in poultry. In the last few years, these viruses have gained much attention because of isolation of many novel APMV serotypes. Currently, there are 13 officially recognized APMV serotypes, and another eight putative APMV serotypes. These APMV serotypes are genetically, antigenically and biologically different. Some of these serotypes appear to be present in specific wild bird species, although other wild and domestic bird species are susceptible. Our understanding about this group of viruses has improved significantly in the last decade because of availability of their full genome sequence information. Reverse genetic systems have also been developed for some of these APMV serotypes. The goal of this chapter is to review our current knowledge of this group of avian viruses read more ...
