Understanding Bacteriophages

The video introduces bacteriophages, viruses that specifically target bacteria. It explains their structure and ubiquity in the environment, including the human body. Bacteriophages are used in food safety to control harmful bacteria, with USDA-approved applications on lunch meats. The video also discusses the potential of phage therapy to selectively target antibiotic-resistant bacteria, offering a promising alternative to traditional antibiotics.

What is a bacteriophage?

• A virus that targets bacteria

• A harmful pathogen

• A beneficial bacterium

• A type of bacteria

How do bacteriophages attach to bacteria?

• Using their capsid

• By their tail sheath

• With their tail fibers

• Through their genetic material

Why are bacteriophages considered useful in food safety?

• They enhance the taste of food

• They increase the shelf life of food

• They can target and eliminate harmful bacteria in food

• They are used as a food preservative

What is the primary benefit of using phage therapy?

• It can target all types of bacteria

• It is a faster treatment than antibiotics

• It is a broad-spectrum treatment

• It selectively targets harmful bacteria while sparing beneficial ones

What is a potential application of phage therapy?

• To improve digestion

• To combat antibiotic-resistant bacteria

• To treat viral infections

• To enhance immune response
