Microorganisms tend to have a relatively fast rate of evolution. Most microorganisms can reproduce rapidly, and bacteria are also able to freely exchange genes through conjugation , transformation and transduction , even between widely divergent species.  This horizontal gene transfer , coupled with a high mutation rate and other means of transformation, allows microorganisms to swiftly evolve (via natural selection ) to survive in new environments and respond to environmental stresses . This rapid evolution is important in medicine, as it has led to the development of multidrug resistant pathogenic bacteria , superbugs , that are resistant to antibiotics . 
An antibody , also called immune globulin (Ig), is a large, Y-shape macromolecule made by plasma cells that's employed by the system to spot and neutralize pathogens like microorganism and viruses . The protein binds to a singular molecule of the harmful agent, referred to as antigen, via the variable region. Antibodies gets secreted by cells of the immune system.
