Bad bacteria can cause disease, food poisoning, waste, bad odors, and decay of food and organic material. While bad bacteria can be harmful, good bacteria can protect people from the effects of bad bacteria at times.
Bad bacteria in the environment cause waste and disease. Food that is not properly stored begins to rot due to bacteria. However, food can be protected from bacteria by freezing, drying, pickling or salting. Preservation slows the growth of or kills bacteria.
Two groups of bacteria cause many types of disease. Cocci are small spheres that cause sore throats, lung infections, pneumonia and meningitis. Bacilli, shaped like rods, cause food poisoning. Other bacteria can cause tetanus, botulism and tuberculosis.
Antibiotics are drugs used to treat diseases caused by bacteria. However, due to the ability of bacteria to adapt to antibiotics, some have become drug-resistant.
Bacteria can produce toxins that cause bad odors and the decay of organic material. These toxins can also cause food poisoning and affect the nervous system.
The best way to avoid becoming ill from bad bacteria is to ensure good physical fitness and health. These preventative measures assist in quick recovery from illness.
Bacteria can live almost anywhere for a very long time. They live in water, the air, plants, animals and the ground.
