A Quiz About Introduction Of Parasitology

Diphyllobothrium latum is a type of tapeworm that infects fish and can cause a condition called diphyllobothriasis in humans. It is commonly known as the fish tapeworm. This tapeworm is acquired by consuming raw or undercooked fish that is infected with the parasite's larvae. Once ingested, the tapeworm grows in the intestines and can cause symptoms such as abdominal pain, diarrhea, and weight loss. Treatment typically involves medication to kill the tapeworm and alleviate symptoms.

Wuchereria bancrofti is a mosquito-borne parasitic worm that causes lymphatic filariasis, also known as tropical elephantiasis. This disease is characterized by the swelling of limbs and other body parts due to the obstruction of the lymphatic system. The mosquito acts as a vector, transmitting the larvae of the worm to humans through its bite. Once inside the human body, the larvae develop into adult worms and reproduce, leading to the chronic infection. Therefore, Wuchereria bancrofti is the correct answer as it is the specific mosquito vector known to cause tropical elephantiasis.

Giardia lamblia is the correct answer because it is known to exhibit falling leaf motility, which refers to its characteristic jerky and tumbling movement. Additionally, Giardia lamblia has a pear shape with two nuclei, often resembling eyes. This description matches the given characteristics mentioned in the question.

Enterobius vermicularis is the correct answer because it is commonly known as the pinworm. Pinworm infection is a common parasitic infection that primarily affects children. It is caused by the Enterobius vermicularis parasite and is characterized by symptoms such as anal itching, irritability, and disturbed sleep. The other options mentioned, Diantameoba fragilis, Trichuris trichiura, and Ascaris lumbricoides, are all different types of parasites but are not specifically associated with pinworm infection.

Paragonimus westermani is the name of the lung fluke. It is a parasitic flatworm that infects the lungs of humans and other mammals. This fluke is commonly found in Asia, particularly in countries where raw or undercooked freshwater crab or crayfish are consumed. Paragonimus westermani causes a disease known as paragonimiasis, which can lead to symptoms such as chronic cough, chest pain, and fever.

The cellophane tape test is used to diagnose Enterobius vermicularis, also known as pinworm infection. This test involves placing a piece of transparent tape against the anus and then examining it under a microscope to look for the eggs of the pinworm. This method is commonly used because pinworm infections often occur at night when the female worms lay their eggs around the anus. By using the cellophane tape test, the eggs can be easily collected and identified, allowing for an accurate diagnosis.

Fasciolopsis buski is the correct answer because it is the name of the giant intestinal fluke. The other options, Giardia Lamblia, Fasciolopsis hepatica, and Opisthorchis sinensis, are names of different parasites and not specifically the giant intestinal fluke.

The correct answer is Schistosoma mansoni because it is the only option listed that is known to have a lateral spine. Schistosoma haematobium, Schistosoma japonicum, and Schistosoma urmom do not have a lateral spine.

Hookworm infection can cause a common symptom known as ground itch. This symptom occurs when the larvae of the hookworm penetrate the skin, causing itching and a rash. Hookworms are parasitic worms that live in the small intestine of infected individuals and can cause various symptoms such as abdominal pain, diarrhea, anemia, and fatigue. Therefore, the presence of ground itch is commonly associated with hookworm infection.

The given options are all different species of bacteria, and the correct answer is E. coli. E. coli, short for Escherichia coli, is a common bacterium found in the intestines of humans and animals. It is a gram-negative, rod-shaped bacterium and is known for its role in causing various infections, as well as its use in scientific research and biotechnology.
