    Journal: Vet Med Nauki; 1982; 19(2):18-24. PubMed ID: 6287709.
    Abstract:
    Stationary tracheal organ cultures of pheasants and chick embryos, treated with a mucolytic agent were used to study the ciliostatic effect of the following viruses: fowl pest (FPV), Newcastle disease (NDV), infections laryngotracheitis (ILV), and infections bronchitis (IBV) - strain Beaudette. In chick embryo tracheal cultures ciliostasis was found to set in as follows: for FPV - at the 24th hour; for NDV - at the 72nd-120th hour; for ILV - at the 168-192nd hour; and for IBV-at the 72nd-96th hour. The ciliostatic effect produced by NDV and IBV coincided in terms of time and dynamics. In pheasant tracheal organ cultures ciliostasis set in as follows: for FPV - at the 24th hour; for NDV - at the 72nd-120th hour; and for ILV - at the 168-192nd hour. This system was shown to be unsusceptible to IBV which produced no effect whatever. In mixed organic cultures, containing several tracheal segments of pheasants and chick embryos each per petri dish IBV did bring about ciliostasis in the chick embryo segments only, within the period after inoculation as cited above. It is stated that pheasant tracheal organ cultures could be employed in the case of an express initial differentiation of FPV, NDV, and ILV, recording the time period for the setting in of full ciliostasis following the inoculation of the respective viruses. Discussed is the possibility of identifying IBV, using mixed tracheal organ cultures of pheasants and chick embryos.
