Bacteriums and viruses
Bacteriums and viruses are very small cells which might cause infections. They can only be observed through a microscope. That’s why they are also called micro-organisms or microbes.
Bacteriums are microbes which can survive anywhere. In the human body, the air, the water, the ground. Besides, bacteriums can multiply very fast. Antibiotics can kill bacteriums and, thus, save lives.
Bacteriums cause amongst others:
- Bacterial meningitis
- Wound infections
- Some types of inflammation of throat/ear.
Without bacteriums it is impossible to live. Bacteriums were the first forms of life on earth. Most bacteriums are harmless and have adapted themselves to their environment. Millions of bacteriums live on our body, for example just think of our intestinal flora. Some, however, are pathogenic organisms. We might get ill, if we get in contact with such a pathogenic organism. How ill, depends on a couple of factors, such as:
- Aggression of pathogenic organisms
- Origin of pathogenic organisms
- The amount of pathogenic organisms which entered the body
- Our state of health and mind,
- How fast our immune system fights these intruders
Viruses are much smaller than bacteriums and act totally different. They don’t have an own metabolism and can’t therefore multiply independently. Viruses need living cells to multiply. They benefit from the cell they enter, by stimulating this cell to produce new viruses. Then, the host cell will be demolished and the virus further penetrates the body. Antibiotics can’t neutralize viruses.
Viruses cause amongst others:
- Acute bronchitis,
- Most types of inflammation of the throat/ear,
- Viral patitis
