Complement activation is triggered by an antibody when it is bound to the antigen. At least 40 species of naturally competent and transformable bacteria have been found. Gram +ve : Bacillus subtilis, Streptococcus pneumonae. Gram –ve: Haemphilus infulenzae, Neisseria gonorrahe, Helicobacetr pylori, Acenetobacter baylyi, Cyanobacteria. Treating a gram-positive infection Penicillin. Penicillin is a common antibiotic that’s used for a variety of infections. It works by interfering with the Glycopeptides.

Complements are soluble proteins and glycoproteins mostly produced by hepatocytes. More than 20 types of complements are present in serum, found circulating normally in human body in inactive forms (called as zymogens or proenzymes).

Although complement activation can occur on the cell membrane of encapsulated bacteria such as Streptococcus pneumoniae, the capsule prevents interaction between C3b deposited on the membrane and the CR1 on phagocytic cells. The complement system, also known as complement cascade, is a part of the immune system that enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane. It is part of the innate immune system, which is not adaptable and does not change during an individual's lifetime. The complement system can, however, be recruited and brought into action by antibodies generated by the adaptive immun The membrane attack complex or terminal complement complex is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host's complement system, and as such is an effector of the immune system.
