Pathogenic bacteria are primarily known for their ability to cause various diseases in humans. Unlike beneficial bacteria, which play key roles in supporting health, such as aiding digestion and maintaining a balanced microbiome, pathogenic bacteria can lead to infections and illnesses. They can disrupt normal bodily functions, create toxins, and provoke immune responses, which may manifest as symptoms ranging from mild to severe illness. In contrast, options referring to the support of healthy gut flora, digestion assistance, and vitamin production relate to non-pathogenic bacteria, which contribute positively to human health. These beneficial bacteria are vital for processes such as breaking down food, synthesizing certain vitamins, and preventing the overgrowth of harmful microorganisms. Understanding the role of pathogenic bacteria is crucial for recognizing the impact of infections on health and the importance of hygiene and preventive measures in healthcare.
