Dried Paper Discs for Serological Identification of Human Mycoplasmas

Abstract

Summary. The preparation of antisera to human mycoplasmas and their use when dried on paper discs are described. The discs were tested in 6 diagnostic laboratories in parallel with locally prepared wet discs as controls. In all 138 mycoplasma strains were examined. Wet and dry discs gave essentially identical results in all but 5% of cases. The dried discs had a shelf life of at least 2 years.
