Persistent infections with Sendai virus and Newcastle disease viruses. 1986

P Lawton, and Z Karimi, and L Mancinelli, and J T Seto

Persistent infections (Pi) were established in two host-cell systems [Madin-Darby bovine kidney (MDBK) and Madin-Darby canine kidney (MDCK)] with Sendai virus and three strains of NDV, to test the influence of different viruses and host-cell systems. Virus was recovered from the persistently infected cells. An RNA- ts mutant was recovered from a Pi of MDBK cells, but no Pi could be established in MDCK cells with the three strains of NDV. Additionally, the Pi was established exclusively by a virulent strain, NDV-Milano. On the other hand, Sendai virus could establish Pi in MDBK and MDCK cell-systems. Several ts mutants were recovered from "late" passages of Pi, and from an accidental infection, a ts mutant with an altered P polypeptide. Ten other ts mutants were tested, however, the specific ts lesion could not be identified. From three Pi in MDCK cells, host range mutants (ts-f1, ts-f2, and ts-f3) were recovered. One of the mutants (ts-f1) has an altered M (matrix) protein. The host range mutants undergo a productive infection in MDBK and MDCK cells, which are nonpermissive for wild type Sendai virus. The possible significance of the results are discussed.

D009522	Newcastle disease virus	The most well known avian paramyxovirus in the genus AVULAVIRUS and the cause of a highly infectious pneumoencephalitis in fowl. It is also reported to cause CONJUNCTIVITIS in humans. Transmission is by droplet inhalation or ingestion of contaminated water or food.	Avian Paramyxovirus 1,Paramyxovirus 1, Avian

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
