| pubmed-article:1180872 | pubmed:abstractText | The cell walls from all 21 species of gram-positive bacteria examined, except lysozyme-susceptible Micrococcus lysodeikticus (NCTC 2665) and lysozyme-resistant Staphylococcus epidermidis (ATCC 155), were found to be definitely adjuvant-active in both stimulation of increased serum antibody levels and induction of delayed-type hypersensitivity to ovalbumin when administered to guinea-pigs as water-in-oil emulsions. Using various cell wall lytic enzymes, the immunoadjuvant principles were solubilized with full retention of the adjuvant activities from walls of Staphylococcus aureus (Copenhagen), Streptococcus pyogens (group A, type 6; S43/100), Streptococcus salivarius (IFO 3350), Streptococcus faecalis (IFO 12580), Streptococcus mutans (BHT), Lactobacillus plantarum (ATCC 8014), Bacillus megaterium (IFO 12068), Corynebacterium diphtheriae (Park-Williams No. 8), Mycobacterium smegmatis, and Actinomyces viscous (ATCC 15987). Evidence was obtained that the non-peptidoglycan portion of the cell walls is not essential for manifestation of immunoadjuvancy. | lld:pubmed |
