The human body is home to a vast array of bacteria, which play important roles in supporting various bodily processes. While some bacteria are harmless or even beneficial, others can cause infections and other illnesses. Examples of harmful bacteria include Staphylococcus aureus, which can cause skin infections, pneumonia, and other illnesses, and Escherichia coli, which can cause food poisoning and other infections. Non-harmful bacteria include Staphylococcus epidermidis, which is found on the skin and is generally non-pathogenic, and Bacteroides fragilis, which is important for digestion in the gut. It's important to note that the categorization of bacteria as harmful or non-harmful is not always straightforward, as some bacteria can have different effects depending on factors like the location in the body and other environmental factors. Understanding the roles that bacteria play in the human body, as well as their potential to cause harm, is important for maintaining overall health and preventing the spread of infectious diseases.
