Bacteria are single-celled microorganisms found everywhere in nature, including the human body. While some bacteria can cause infections, many play essential roles in digestion, immunity, and environmental health.

Types of Bacteria:
- Beneficial Bacteria: Support health by aiding digestion, synthesizing vitamins, and balancing harmful bacteria. Commonly found in the gut and in probiotics, they help maintain a healthy microbiome.
- Neutral Bacteria: Present in the body without significant positive or negative effects; they contribute to microbial diversity without impacting health directly.
- Pathogenic Bacteria: Can cause infections or illness if they overgrow or enter parts of the body where they don’t belong.
Importance:
- Probiotics: Certain beneficial bacteria are included in supplements and foods to promote a balanced gut microbiome.
- Environmental Role: Bacteria are essential for breaking down organic matter and cycling nutrients in ecosystems, aiding soil fertility and water quality.
