Abstract:
PROBLEM TO BE SOLVED: To provide a method for adapting arterivirus to a cell line and for attenuating the arterivirus. SOLUTION: This method for determining a reproducing capacity of the arterivirus comprises the determination of an amino acid at a specific position of GP2a of PRRSV isolate I-1102 in green monkey cell line. By the method for producing the arterivirus for increasing the yield of the arteivirus, the virulence of the arterivirus is maintained in the green monkey cell line. The method for determining the attenuation of the arterivirus comprises the determination of an amino acid at a specific position of GP5 of PRRSV isolate I-1102 and an amino acid at a specific position of ORF1ab. The method for attenuating the virulence of the arterivirus is to change the amino acids. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a method for generating an infectious Newcastle disease virus (NDV) entirely from cloned full-length cDNA: and to provide a vaccine and a diagnostic assay generated with and derived from the method. SOLUTION: The method offers the possibility to modify an NDV genome by means of genetic modification and allows the introduction of mutations, deletions, and/or insertions. The method can be used to modify the virulence of NDV, thereby generating new attenuated live vaccines with enhanced properties. The method can be used to modify the antigenic make-up of NDV, thus allowing the generation of live NDV marker vaccines which can be serologically distinguished from NDV field strains.

Abstract:
The invention relates to the field of Arteriviruses and vaccines directed against infections caused by these viruses. The invention provides an Arterivirus-like particle comprising at least a first structural protein derived from a first Arterivirus and a second structural protein wherein said second structural protein is at least partly not derived from said first Arterivirus.

Abstract:
The invention relates to the production of gonadotrophins and corresponding receptors in transgenic plants. The invention provides a method to produce a gonadotrophin or its corresponding receptor in a transgenic plant with modified glycosylation machinery, in order to allow for mammalian type of glycosidic side chains of gonadotrophin and its corresponding receptor.
