Newcastle disease virus (NDV) is an important pathogen in poultry. Waterfowl and a number of other avian species serve as the host for NDV. Severity of the disease is variable and infected animals mainly develop respiratory and neurological symptoms. Outbreaks of NDV in poultry are recorded regularly in the Republic of Kazakhstan despite the widespread use of vaccines. Here we present evidence that nucleic acid found in open water bodies in Kazakhstan can be detected by means of next-generation sequencing and belongs to at least three distinct genotypes of NDV.
