Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Summary Introduction

Introduction:

Toxoplasma gondii is an obligate intracellular parasite which has the ability to invade and penetrate the immune system of the host. It can attack various species of birds and mammals.

Expert Solution & Answer

Answer to Problem 1Q

Correct answer:

A pathogen-host which is involved to make the rodent host inevitable to host cat species is Toxoplasma gondii.

Therefore, option (d) is correct.

Option (d) is given as “Toxoplasma gondii”.

Explanation of Solution

Justify the reason for the correct statement:

This parasite enters the intestine of cat and is released in the feces in the form of oocysts. It is released in the soil. It transmits to other organisms like rodents and birds. When rats are infected with this organism, then they lose the fear of being eaten by cats.

Hence, option (d) is correct.

Justify reasons for incorrect statements:

Option (a) is given as “Cryptococcus neoformans”.

It causes disease meningitis. Hence, it is a wrong answer.

Option (b) is given as “Neisseria meningitidis”.

They are gram-negative diplococcus bacteria. Hence, it is a wrong answer.

Option (c) is given as “rabies virus”.

Rabies is caused in humans after biting of dogs. Hence, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Infected rodents with a strain of Toxoplasma gondii lose the fear of being eaten by cats, thus they become inevitable for the host cat.
