What is pathogenic bacteria?
- Bacteria that cause disease are known as pathogenic bacteria. Most bacteria are harmless and often beneficial, but some can cause infectious diseases. It is estimated that there are fewer than a hundred of these pathogenic species in humans.
- Infections are not caused by all bacteria. Pathogenic bacteria are those that can cause disease. When your immune system is weakened by a virus, your body is more vulnerable to bacterial infections. A virus-caused disease state allows normally harmless bacteria to become pathogenic.
- They can be found in almost every environment on the planet, and the bacteria carried by the average human, primarily in the gut, outnumber human cells.
- Untreated fruits and vegetables, raw meat products, raw milk products, and water are frequently sources of bacterial infection.
