Document Summary
Immunology: the study of physiological mechanisms that humans and other animals use to defend their bodies from invasion by infectious organisms. 2: antibiotic treatment can disrupt the natural ecology of the colon microbiota, allows pathogenic bacteria to establish themselves. What happens is that antibiotics disrupt your microbiota. Anything that disrupts this balance leads to symptoms. Big problem is if any bacteria damage that barrier and crosses then you have a problem. Innate immunity or natural immunity: defense mechanism that acts immediately at beginning of infection and do not adapt to a particular pathogen or generate immunological memory.

These complement proteins covalently bind to pathogen and the complement protein gets cleaved into two pieces.
