A parasite that lives on the external surface of its host.

A parasite that lives inside the body of its host.

A parasite that completely depends on its host for survival throughout its life cycle.

An organism that can survive both with or without a host.

The host where a parasite reaches adulthood and undergoes sexual reproduction.

The host where a parasite undergoes larval development or asexual reproduction.

A temporary host that doesn't contribute to the parasite's life cycle.

A host that harbors a parasite and can transmit it to other hosts.

A close relationship where one organism (parasite) benefits by living on or inside another organism (host), causing harm to the host.

The organism that is harmed by a parasite in a parasitic relationship.

A relationship where both organisms benefit, but it's not essential for survival.

A close relationship where both organisms benefit and depend on each other for survival.

A temporary association where one organism uses another for transport, with no metabolic dependence.

Single-celled organisms, like Plasmodium (malaria).

Multicellular organisms, like worms and ticks.

The study of parasites is crucial because many parasites cause major health problems worldwide.

A large intestinal trematode (fluke) infecting humans and pigs, particularly in Southeast Asia. Adults reside in the upper intestine, causing inflammation, ulceration, and bleeding.

A liver fluke that primarily infects sheep, but humans can become infected by consuming metacercariae in watercress. Adults reside in the bile ducts of the liver, causing 'Fascioliasis' which can lead to anemia.

A common liver fluke found in East Asia, acquired by consuming raw or pickled fish containing infective metacercariae. Adults reside in the bile ducts.

A lung fluke widespread in East and Southeast Asia. Acquired by consuming infected crustaceans (like crabs or crayfish). Adults reside in the lungs.

A type of flatworm commonly known as tapeworms. They are intestinal parasites that can cause various infections.

A type of cestode (tapeworm) commonly found worldwide. It is acquired through consuming contaminated, uncooked beef and causes minimal symptoms in most cases.

Another cestode (tapeworm) found worldwide. It's spread through consuming contaminated, uncooked pork and can lead to a more serious condition called cystercicosis.

A systemic disease caused by Taenia solium. It involves the larvae of the tapeworm encysting in muscles and the brain, potentially leading to epilepsy.

A type of cestode (tapeworm) that primarily affects dogs. Humans can become infected by ingesting the larval stage, leading to hydatid disease.

A condition caused by the larval stage of Echinococcus granulosus. It can occur when humans ingest the larvae, which develop into cysts in various organs like the liver or brain causing space-occupying lesions.

A type of nematode worm that commonly infects dogs and cats. Humans can become infected by ingesting embryonated eggs from animal feces, causing visceral larva migrans.

A condition caused by the larval stage of Toxocara. It happens when humans ingest the eggs and the larvae migrate through the body, causing damage to various organs.

A type of filarial worm spread by the simulium black fly. It can cause visual impairment, blindness, and severe skin itching.

A type of filarial worm that causes lymphatic filariasis, a debilitating disease impacting the lymphatic system.

A type of roundworm that infects the small intestine. It is spread through the fecal-oral route and prevalent in warm, humid environments.

Parasitic worms that burrow into the skin and live in the small intestine. They can cause anemia due to blood loss.

A parasitic roundworm that lives in the large intestine and can cause diarrhea and rectal prolapse.

A parasitic roundworm that lives in the small intestine and can cause severe infections in people with weakened immune systems.

A small parasitic worm that lives in the colon and rectum and is most common in children. It is spread through the fecal-oral route.

A mode of transmission of parasites where infected feces contaminates food or water, which is then ingested by another individual.

A serious mosquito-borne disease caused by a parasite that infects red blood cells. It can be fatal if left untreated.

Parasitic flatworms that infect the bladder and intestines. They can cause bladder and intestinal problems.

A condition caused by a deficiency of red blood cells or hemoglobin, resulting in a decrease in oxygen-carrying capacity of the blood.

Frequent loose or watery stools.
