(2) Litšobotsi tsa Etiological

Ho ea ka li-antigenicity tse fapaneng: e arotsoe ka li-serotypes tse 3: A, B, le C. Mofuta oa A o ka tšoaetsa liphoofolo tse sa tšoaneng, 'me feberu ea linonyana ke ea mofuta oa A.

HA e arotsoe ka mefuta ea 1-16, 'me NA e arotsoe ka mefuta e 1-10.Ha ho na tšireletso pakeng tsa HA le NA.

Ho khetholla pakeng tsa feberu ea linonyana le lefu la Newcastle lefu la kokoana-hloko, kokoana-hloko ea avian influenza e ka bokellana liseleng tse khubelu tsa mali tsa lipere le linku, empa lefu la Newcastle lefu la khoho ha le khone.
