In vivo changes in complement induced with peptidoglycan-polysaccharide polymers from streptococcal cell walls

Infect Immun. 1982 Jan;35(1):377-80. doi: 10.1128/iai.35.1.377-380.1982.


In rats injected with an arthropathogenic dose of streptococcal cell wall fragments, serum hemolytic activity decreased over the first 24 h and was then elevated from days 2 through 6 after injection. Hemolytic activity was again elevated at days 16 and 40. Levels of activity of alternative complement pathway, C3, and factor D were also altered.
