What type of bacteria are known to cause disease?

1. Beneficial bacteria

2. Pathogenic bacteria

3. Antibacterial bacteria

4. Non-pathogenic bacteria

The correct answer is: Pathogenic bacteria

Pathogenic bacteria are those that have the capability to cause disease in humans or other living organisms. These bacteria can invade host tissues, multiply, and produce harmful toxins, leading to infections and various illnesses. Examples of pathogenic bacteria include Streptococcus, Staphylococcus, and Escherichia coli under certain conditions. On the other hand, beneficial bacteria play a crucial role in processes like digestion, food production, and the maintenance of a healthy microbiome without causing disease. Antibacterial bacteria typically refer to those that inhibit the growth of harmful bacteria but are not a distinct category of bacteria that cause disease. Non-pathogenic bacteria are organisms that do not cause disease and are often harmless or even beneficial to their host. Therefore, the identification of pathogenic bacteria as the correct answer is essential in understanding their role in health and disease management.
