The Spectral Geometry of Riemann Surfaces

Abstract

Riems FMD two-component oil emulsion vaccine was subcutaneously applied (5 ml) under field conditions to 855 store pigs of different age groups (trivalent--O1, A5, C). It produced early onset of lasting strong immunity against the three above FMD virus types. General condition of the animals and their body weight development were not adversely affected. Pea-size to walnut-size vaccination granulomas were recorded on slaughter as locally delimited reactions in 15 to 20 percent of vaccinated animals and were found to be morphologically correlated to adjuvant action. They were easily removed from the carcasses by excision of the vaccination point, with only minor loss of slaughter substance.
