Question: 1 / 400

Which bad bacteria is a harmful microorganism that can cause diseases?

Non-pathogenic bacteria

Non-pathogenic bacteria are considered harmless because they do not cause diseases. On the other hand, pathogenic bacteria are harmful microorganisms that have the ability to cause diseases in humans. Parasites are a separate type of harmful microorganism that can also cause diseases, but in this context, the question specifically asks for a type of bacteria. Viruses, while also capable of causing diseases, are not bacteria; they are distinct entities that require a host cell to replicate. Therefore, the correct answer is A - pathogenic bacteria.
