An example of a good prokaryote is Lactobacillus Casei. It is helpful and beneficial to the human body because of it's ability to restrict the growth of harmful bacteria. It is naturally found in the mouth and intestines of the human body and is also found in raw diary products and fresh plant products. It also improves digestion,  helps control diarrhea, reduce lactose intolerance and have an anti-inflammatory effect on the gut.

An example of a harmful microorganism is Streptococcus pyogenes.  Its symptoms include strep throat, scarlet fever,  impetigo (infection of outer layers of skin), and cellulitis (infection of deeper layers of skin). It's one of the most frequent causes of diseases for humans and is estimated that about 5-15% of people that have this bacteria show no signs of diseases. It has been described as a "flesh eating bacteria" and killed many people mainly because it is the most important cause of puerperal fever.
