Interpretive Summary: There are currently 13 recognized serotypes of avian paramyxovirus. Type 1 is the most important for poultry and includes Newcastle disease virus (NDV), which is a form of avian paramyxovirus type 1 (APMV-1) that is highly virulent for chickens and turkeys. NDV is considered to be one of the most economically important diseases of poultry production worldwide and is reportable to the world animal health association (OIE). NDV is endemic in many areas of Asia, South America, Africa and the Middle East and can be carried asymptomatically by wild waterfowl. Numerous avian species are susceptible to infection with APMV-1 and there are variations among APMV-1 strains in virulence. Mild strains (lentogenic) can cause respiratory disease, but the most concern is with infection by the severe forms called NDV (or called a velogenic strain). A third form, mesogenic, is “between” velogenic and lentogenic in disease severity. This book chapter describes the essential clinical and diagnostic features of avian paramyxoviruses in poultry.

Technical Abstract: Newcastle disease virus (NDV) is a form of avian paramyxovirus type 1 (APMV-1) that is highly virulent for chickens and turkeys. There are currently 13 recognized serotypes of avian paramyxovirus, but APMV-1, including NDV, is the most important for poultry Newcastle disease (ND) is considered to be one of the most economically important diseases of poultry production worldwide and is reportable to the World Organization for Animal Health (OIE). NDV is endemic in many areas of Asia, South America, Africa and the Middle East and can be carried asymptomatically by wild waterfowl. Numerous avian species are susceptible to infection with APMV-1. There are variations among APMV-1 strains in terms of virulence, and strains are classified as lentogenic, mesogenic or velogenic flocks, which remain unvaccinated. Good quality APMV-1 vaccines protect against disease and mortality from NDV when applied properly. In addition to NDV and less virulent APMV-1 strains, APMV type 2 (APMV-2), APMV type 3 (APMV-3) and APMV type 7 (APMV-7), although relatively rare can cause disease in turkeys and chickens.
