Roundworms are described as:

Roundworms are described as:

• A. Intestinal parasite that looks like spaghetti and is passed in feces or vomit
• B. External parasites on fur
• C. Bacteria causing diarrhea
• D. A virus causing coughing

Answer: (A)

Roundworms are intestinal parasites, a type of worm that lives in the animal’s digestive system. They look like long, spaghetti-like strands and are typically passed out in the animal’s feces, and sometimes can be seen in vomit when the infection is heavy. This description matches the choice that describes them as an intestinal parasite resembling spaghetti and shed in feces or vomit. They are not external parasites on fur (that would be things like fleas or ticks), not bacteria, and not a virus. Infections can cause gastrointestinal signs and, especially in puppies, a swollen or pot-bellied appearance; larvae can also migrate and, in some cases, cause coughing.
