About this Research Topic
Newcastle disease (ND) caused by Newcastle disease virus (NDV) occurs worldwide and is considered one of the most important viral diseases of poultry. There are three different pathotypes of NDV- velogenic, mesogenic, and lentogenic. Outbreaks due to velogenic strains occur frequently in LMICs in spite of regular vaccination of domestic poultry. Since the discovery of NDV, many new genotypes of NDV are identified. In recent years, the number of reported genotypes of NDV has increased suggesting continuous evolution of the virus leading to the emergence of genetic variants. The NDV affect large poultry population and causing heavy economical loses in LMIC. Recently many countries have reported vNDV in wild birds indicating at possible host range expansion of the virus. There is a need to compile all available information on these variants in LMICs poultry sector including epidemiology, diagnosis, pathotypes, genotypes, and vaccination etc.
To highlight successes and challenges associated with Newcastle disease for poultry sector in low- and middle-income countries (LMICs). The overall goal is to understand the epidemiology, clinical signs, diagnosis, prevent and control of Newcastle disease in poultry in LMICs. The proposed research topic will focus on understanding the spread of ND in LMIC, the challenges it offers and to provide insight into future strategies to tackle disease. Hence, manuscripts focused on hypothesis-driven science-based studies will be considered for review and publication whilst basic surveys of NDV in these regions will not be considered.
This Research Topic welcomes, but is not limited to, the following themes:
• Prevalence of NDV
• Molecular characterization of emerging and re-emerging NDVs
• Prevention and control
