Question

All nematodes cause disease. So you should always wash your hands after touching dirt. True or False.

Answer 1

Statement is False.

There are two types of nematodes:

* Harmful nematodes: These nematodes cause disease in human beings. So we should wash our hands after working on them.

* Beneficial nematodes: These nematodes are found in soil and controls the pest in the agriculture. They are species specific. They give problem to the pest only. They don't harm the non target organism such as pollinators and humans. That's why no gloves are used while working on them. Hence no need of washing hands in such beneficial nematodes.

But for precaution, we should wash our hands after working in soil. Because there are chances that pathogenic nematodes are in the sool.
