👉 Newcastle fluid, also known as Newcastle disease virus (NDV) or NCDV, is a type of paramyxovirus that primarily affects poultry, causing Newcastle disease. This virus was first identified in Newcastle, England, where it led to significant economic losses due to high mortality rates and reduced productivity in affected flocks. The virus is characterized by its lipid envelope and single-stranded RNA genome, which allows it to efficiently infect host cells. Newcastle fluid has been a major concern in the poultry industry, prompting the development of vaccines to protect birds from infection. The fluid's impact extends beyond poultry, as it can also infect other mammals like pigs and humans, though human infections are rare and typically mild.
