Survival during H.T.S.T pasteurisation by M. paraTuberculosi - FS1038

Investigation into the ability of M. paratuberculosis to survive high temperature short time pasteurisation utilising strains of paratuberculosis shown to be resistant to the HTST process in studies carried out at Queens University Belfast. Pasteirisation being achieved by use of a laboratory scale pasteuriser (Armfield FT34) milk inoculum and recovery methods being as similar as possible to those used in Belfast.
To establish whether viable M.paraTB can survive HTST pasteurisation using one of the DANI strains of M.paraTB which exibited the "tailing" effect; using milk obtained aseptically from a cow using the DANI method; and DANI growing methods.
