b. topical application of griseofulvin
c. moist compresses applied frequently
d. administration of systemic antibiotics

Answer 1

A) applying pyrethrins to the body

Step-by-step explanation:

Pediculus humanus corporis is the scientific name of the body lice which are considered the ectoparasites (2-4 mm in length) and feed on the human blood to survive.

The body lice spread disease such as relapsing fever, trench fever and lay eggs in the stitching of the clothes.

The body lice are treated by pediculicides like Pyrethrin and piperonyl butoxide shampoo which act by killing the ice. The pyrethroid compounds act by penetrating the nervous system of the insects which causes paralysis of the insect and kills the insect-like lice.

Thus, Option-A is the correct answer.

Answer 2

Applying pyrethrins to the body.

Step-by-step explanation:

Parasites may be defined as the organisms that can obtain their ready made food from the host. The lice on human hair is the best example of exoparasites.

Pediculosis may be defined as the condition in which human hair is clogged and infected by the lice and their eggs. This can be treated by using the chemical pyrethrins in the shampoo. The pyrethrin chemical can kill the eggs of the lice and useful in the treatment of pediculosis.

Thus, the correct answer is option (a).
