Method and plant for simultaneously bringing a plurality of liquid samples on an object suppor- ting plate (2), particularly serums on an object supporting plate covered with cellular cultures. The liquid samples are pushed by means of a multiple pipette (3) through a funnel board (4) securely arranged on the object carrier plate (2) and provided with a plurality of funnel-shaped containers (5) arranged next to each other in one plane. The funnel board (4) is preferably left on the object carrier plate (2) covered with cellular cultures until incubation of ther serum has oc- curred. This method enables to avoid the flowing of serums and insures a simple and easy man- ipulation for research purposes in laboratory.

Richard James LYSONS, 2 Blackwood Cot- tages, Streatley, Reading, Berkshire RG8 9SR, United Kingdom assigned to NATIONAL RESEARCH DEVELOPMENT CORPORA- TION Existing vaccines against swine dysentery are not very effective. It has now been found that an effective regime of vaccination comprises ad- ministering parenterally to pigs a priming dose of killed virulent or pathogenic T. hyodysen- teriae) effective to stimulate the immune response of the pig to a subsequent dose of a live avirulent or non-pathogenic strain of T. hyodysenteriae) and at about the same time or thereafter administering this live strain orally. The invention provides a kit for use in such a method. The live strain is preferably NCTC 11628 deposited as a Budapest Treaty patent deposit.

BOER Gerben Foppe DE, Jagersveld 34, NL- 8222 AC Lelystad, Netherlands assigned to CENTRAAL DIERGENEESKUND1G IN- STITUUT A highly immunogenic virus preparation derived from a Marek's disease virus strain, belonging to Avian Herpesvirus serotype-I by attenuation employing serial passages in Avian cell culturcs and plaque purification. The pre- ferred parent virus is the virus strain MDV CVI- 988 which has been recovered from a healthy chicken (Avian diseases 16: 108-125, 1972). The live purified Marek's disease vaccine so obtained is innocuous for specific pathogen free Rhode Is- land Red chickens which are highly susceptible for development of Marek's disease tumours. The monovalent virus preparation according to the invention demonstrated, in comparison with
