How would you describe a "virulent" strain of bacteria?

Non-threatening
Highly contagious and harmful
Slow-acting and benign
Moderately harmful

The correct answer is: Highly contagious and harmful

A "virulent" strain of bacteria is best described as highly contagious and harmful. The term "virulent" specifically refers to the severity or harmfulness of a pathogen, indicating that it is capable of causing significant disease or infection and can spread easily from one host to another. Such strains often possess factors that enhance their ability to invade host defenses, multiply rapidly, and produce toxins, making them particularly dangerous in medical contexts. In contrast, terms like non-threatening, slow-acting and benign, or moderately harmful suggest a lesser degree of danger or impact, which does not align with the definition of virulent. The emphasis on increased infection risk and potential for serious health effects makes the description of virulent strains crucial for understanding public health and disease management.
