The task is to identify five characteristics of Listeria monocytogenes from the given list. Here are the characteristics and their explanations:

1. Resistant to pH extremes: Listeria monocytogenes can survive in a wide range of pH levels, which allows it to persist in various environments, including acidic foods.

2. Intracellular parasite: Listeria monocytogenes is known to invade and live within host cells, particularly macrophages, which helps it evade the host's immune system.

3. Flagellated: Listeria monocytogenes is motile due to the presence of flagella, especially at lower temperatures (below 30°C).

4. Resistant to cold: Listeria monocytogenes can grow at refrigeration temperatures, which is why it is a concern in refrigerated foods.

5. Resistant to heat: Listeria monocytogenes is relatively resistant to heat compared to other non-spore-forming bacteria, but it is not as resistant as spore-forming bacteria.

The five characteristics of Listeria monocytogenes are:

• Resistant to pH extremes
• Intracellular parasite
• Flagellated
• Resistant to cold
• Resistant to heat
