What are the six orders of viruses established by the ICTV, and how can we classify them?

This page discusses Microbiology, specifically the classification of viruses into different orders by the ICTV (International Committee on Taxonomy of Viruses). To practice English with this text, let's start with a comprehension exercise: Step 1: Read the introduction. The first paragraph explains how virus orders are established and that names are italicized. Step 2: Identify the main topic of the entire page. The main topic is the six orders of viruses that have been established. Step 3: Choose one of the virus orders (1-6) and try to explain in one sentence what kind of virus it is. For example, for "1-Caudovirales", you could say: "Caudovirales are tailed dsDNA bacteriophages." Try this for any one of the other five orders. 3 done, 2 left today. You're making progress.
