PATHOLOGY

Detailed explanation-1: -A tapeworm is a flat, parasitic worm that lives in the intestines of an animal host. It commonly infects many different animals, including humans, livestock and domestic cats and dogs (usually meat-eating mammals.)

Detailed explanation-2: -Nematodes (roundworms), cestodes (tapeworms), and trematodes (flatworms) are among the most common helminths that inhabit the human gut. Usually, helminths cannot multiply in the human body. Protozoan parasites that have only one cell can multiply inside the human body.

Detailed explanation-3: -The three common types of tapeworms are Taenia solium, found in pork; Taenia saginata, found in beef; and Diphyllobothrium latum, found in fish. Tapeworm eggs are for the most part ingested through food, water, or soil contaminated with human or animal host excrement.

Detailed explanation-4: -Both the tapeworm infection, also known as taeniasis, and cysticercosis occur globally. The highest rates of infection are found in areas of Latin America, Asia, and Africa that have poor sanitation and free-ranging pigs that have access to human feces.
