How Bacteriophages are Revolutionizing the Fight Against L. monocytogenes in the Food Industry

Bacteriophages, also known as phages, are viruses that infect and replicate within bacteria. These viruses are widely present in nature and are considered to be the most abundant biological entities on the planet. In recent years, bacteriophages have emerged as a promising alternative to antibiotics for the control of bacterial infections. Among the bacterial infections that bacteriophages can target is Listeria monocytogenes , a pathogenic bacterium that can cause serious foodborne illness in humans.

Listeria monocytogenes is a gram-positive bacterium that is commonly found in soil, water, and food. It is a facultative intracellular pathogen, which means that it is capable of invading and replicating within host cells. Listeriosis, the disease caused by Listeria monocytogenes , can range from a mild flu-like illness to a severe invasive disease that can lead to sepsis, meningitis, and even death, particularly in vulnerable populations such as pregnant women, the elderly, and immunocompromised individuals
