How Bacterias Affect To Our Life

- Lysis and Release: After assembly, the mature phage particles trigger lysis of the bacterial cell, releasing new progeny phages to infect other cells.
T he T4 bacteriophage serves as an invaluable tool for understanding viral biology, bacterial genetics, and has promising applications in biotechnology and medicine. Its intricate life cycle and well-characterized genome continue to make it a subject of intense scientific interest and exploration.

MAD COW BACTERIA

Mad cow disease, also known as bovine spongiform encephalopathy (BSE), is not caused by bacteria, but by prions. Prions are abnormal and infectious forms of proteins that affect the brain. BSE is a neurodegenerative disease in cattle that can be fatal and has raised significant public health concerns due to its potential to infect humans.
- Animal-to-Animal Transmission: BSE is believed to have originated from the consumption of feed containing infected cattle by-products.
- Human Health Concerns: BSE has garnered attention due to its potential to cause variant Creutzfeldt-Jakob disease (vCJD) in humans, which is a rare, but fatal, brain disorder.
- Animal-to-Animal Transmission: BSE is believed to have originated from the consumption of feed containing infected cattle by-products.

E COLI BACTERIA
Escherichia coli (E. coli) is a diverse group of bacteria commonly found in the lower intestines of warm-blooded organisms. Many strains of E. coli are harmless and even beneficial, aiding in digestion and competing with harmful bacteria. However, certain strains can cause illness, ranging from mild intestinal discomfort to severe foodborne diseases.

Beneficial Aspects
1. Gut Microbiota: Many strains of E. coli are part of the normal gut flora in humans and warm-blooded animals, contributing to the healthy functioning of the digestive system.
2. Synthesis of Vitamin K: Certain strains of E. coli assist in the production of vitamin K in the intestine, which is an essential nutrient for blood coagulation and bone health.
3. Competitive Exclusion: Beneficial strains of E. coli can compete with harmful bacteria, thereby preventing colonization by pathogenic microorganisms.
