Isolation of Yucaipa-like avian paramyxoviruses from migrating coots (Fulica atra) wintering in Israel.

Two hemagglutinating (HA) agents were isolated from coots (Fulica atra). One of them was isolated from a brain specimen, the specimens being taken from 8 dead birds. The other one was isolated from a tracheal swab, the tracheal and cloacal swabs being taken from 47 apparently healthy birds. Both the agents were identified as Yucaipa-like avian paramyxoviruses (PMV-2) by means of HA inhibition (HI) and neuraminidase (Nase) inhibition (NI) tests. This is the third species of feral birds and the second species of migrating waterfowl in Israel from which Yucaipa-like viruses were isolated.
