To minimize competition some microbes produce antibiotics to restrict the growth of other microbes. Microbes that makes antibiotic are not susceptible to them – they have a Kevlar body suit of sorts. Let’s look at two examples of antibiotics that you are probably familiar with that are produced by fungi and bacteria.

vaccines are used to prevent infections. Vaccines can work by using parts of the pathogen or a whole inactive pathogen to stimulate the immune system. When our body meets a live pathogen during an infection, the pathogen is recognized by a primed immune system and can swiftly mount a response to eradicate the infection
