Patent Report preventing diarrhoea. The microorganism used may be a 987P-producing E. coli bacterium; this may be a natural toxinproducer or an artificially produced bacterium from which the toxin-producing characteristic has been removed or weakened by e.g. genetic engineering. The bacterium may be a nontoxic E. coli strain which contains a plasmid which encodes the 987P fimbria production gene. 020-87

Preparation of foot-and-mouth disease virus in tissue culture: inactivated vaccine for pig

Seils H

Univ. lllinois Found. US 4596 707; 24 Jura 1986 A vaccine, conferri lg protection from Babesia infection, which contains a synthetic merozoite antigen. The antigen reacts specifically in vitro with serum antibodies which neutralize the infectivity of Babesia merozoites. 1129-87

The recovery of foot-and-mouth disease virus (FMDV) from tissue culture for the preparation of inactivated biologically active vaccines for pigs comprises cultivating the tissue culture from permanent cells in large round flasks (preferably 10 1) using a known process, especially a roll process, of cultivation. After a closed cell lawn has been formed, this is infected with FMDV at the multiplication phase of the virus and the culture suspended in a medium. The virus is multiplied for 12 36 h and then harvested by conventional methods. Preferably the cells are cultivated in the flasks in a medium based on physiological saline with additives. This process can be used for the production of vaccines suitable for the immunization of pigs. Relatively large fermentation flasks can be used and the cell culture medium is of simple composition. In an example BHK-21 cells were cultivated in Roux flasks for continuous cultivation using Eagle's medium. Inactivation of the virus is carried out using heat and formalin. 021-87

Quality assurance and testing in vaccine production for determination of surface antigens of e.g. Escherichia coil

US 4596 709; 24 June 1986 Immunostimulating glycoproteins obtained from Klebsiella pneumoniae. The glycoproteins are water soluble and have a molecular weight of about 350 000 daltons. They are recovered by gel filtration of a glycoprotein fraction prepared from a lysate of a Klebsiella pneumoniae culture. 030-87

Safe vaccine for hepatitis containing polymerized serum albumin

Univ. Cali]: US 4596 792; 24 June 1986 A vaccine effective against hepatitis infection in which the immunogenic component is polymerized serum albumin, free from hepatitis virus-derived protein or nucleic acid. The serum albumin is administered as a six to twelve unit polymer with an acceptable adjuvant. 031 87
