Questions and Answers
- 1.
Disease resulting from infection with parasitic tapeworms belongs to teania species
- A.
Taenia Coliasis
- B.
Taeniasis
- C.
Cyticercosis
Correct Answer(s)
B. Taeniasis
C. CyticercosisExplanation
The correct answer is Taeniasis, Cyticercosis. Taeniasis refers to the infection caused by adult tapeworms of the Taenia species in the intestines of humans. Cysticercosis, on the other hand, is the infection caused by the larval stage of the tapeworm in the tissues of humans. Both diseases are a result of infection with parasitic tapeworms, but they occur at different stages of the tapeworm's life cycle and affect different parts of the body.Rate this question:

Tissue infection caused by Taenia Solium
- A.
Cyticercosis
- B.
Taeniasis
Correct Answer
A. CyticercosisExplanation
Cyticercosis is the correct answer because it refers to a tissue infection caused by the parasite Taenia solium. This infection occurs when the larval stage of the parasite, called cysticercus, invades various tissues in the body, including the muscles, brain, and eyes. It can lead to a range of symptoms depending on the affected organ, such as seizures, headaches, and visual disturbances. Taeniasis, on the other hand, refers to the infection caused by the adult tapeworm in the intestines, which is a separate condition from cyticercosis.Rate this question:

Host of Taenia Solium
- A.
Pigs
- B.
Humans
- C.
Both
- D.
None
Correct Answer
C. BothExplanation
Taenia solium is a parasitic tapeworm that can infect both pigs and humans. Pigs serve as the intermediate host for this parasite, meaning that the larvae develop in their muscles. Humans can become infected by consuming undercooked pork that contains the larvae. Once inside the human host, the tapeworm can cause a condition called taeniasis. Therefore, the correct answer is "Both" because both pigs and humans can be hosts for Taenia solium.Rate this question:

Host of Taenia Saginata
- A.
Cow
- B.
Human
- C.
Both
- D.
None
Correct Answer
C. BothExplanation
Taenia saginata is a tapeworm species that can infect both cows and humans as its hosts. In cows, it causes a condition called bovine cysticercosis, where the larvae form cysts in the muscle tissue. When humans consume undercooked or raw beef contaminated with the larvae, they can become infected with the tapeworm. Once inside the human intestines, the tapeworm can grow and produce eggs, leading to symptoms such as abdominal pain, nausea, and weight loss. Therefore, the correct answer is both cow and human as hosts of Taenia saginata.Rate this question:

Morphology of adult worm
- A.
Onchospheres
- B.
Scolex
- C.
Proglottids
- D.
Strombila
Correct Answer(s)
B. Scolex
D. StrombilaExplanation
The given answer, scolex and strobila, refers to different parts of the morphology of an adult worm. The scolex is the anterior end of the worm, usually equipped with hooks or suckers for attachment to the host. The strobila, on the other hand, refers to the segmented body of the worm, which is made up of proglottids. Each proglottid contains reproductive organs and as the worm grows, new proglottids are added at the anterior end while the older ones are pushed towards the posterior end. Therefore, scolex and strobila are both important components of the morphology of an adult worm.Rate this question:

Organ of attachment4 suckers with hooklets
- A.
Onchospheres
- B.
Scolex
- C.
Strombila
Correct Answer
B. ScolexExplanation
The correct answer is "scolex." The term "scolex" refers to the organ of attachment in certain parasites, such as tapeworms. It is characterized by having suckers and hooklets, which allow the parasite to attach itself to the host's intestinal wall. The scolex is an important structure for the survival and reproduction of these parasites.Rate this question:

Glutathione S-Transferase
Correct Answer
B. ParamyosinExplanation
Paramyosin is a protein that is known to possess parasite-killing properties. It is found in various organisms, including parasites, and is involved in their muscle function. Paramyosin has been shown to play a role in the immune response against parasites by activating the production of antibodies. These antibodies can then target and eliminate the parasites. Therefore, paramyosin can be considered as a substance that contributes to the killing of parasites.Rate this question:

Taeniastatin
- B.
Paramyosin
- C.
Sulfated polysaccharide
- D.
Antibodies
- E.
Glutathione S-Transferase
Correct Answer
C. Sulfated polysaccharideExplanation
Sulfated polysaccharide is the correct answer because it is known to direct complement activity away from the parasite. This means that it helps to prevent the complement system from attacking the parasite and instead redirects it towards other targets. Sulfated polysaccharides have been found to have immunomodulatory properties and can inhibit the activation of the complement system, which plays a crucial role in the immune response against parasites. By directing complement activity away from the parasite, sulfated polysaccharides can help the parasite evade the immune system and survive in the host.Rate this question:

Glutathione S-Transferase
Correct Answer
E. Glutathione S-TransferaseExplanation
Glutathione S-Transferase is the correct answer because it is an enzyme that plays a crucial role in detoxification. It catalyzes the conjugation of glutathione with various toxic compounds, making them more water-soluble and easier to eliminate from the body. This enzyme is involved in the metabolism of many drugs, toxins, and carcinogens, making it an important component of the body's defense against harmful substances.Rate this question:

Glutathione S-Transferase
Correct Answer
D. AntibodiesExplanation
Antibodies are proteins that are produced by the immune system in response to the presence of foreign substances in the body. They play a crucial role in defending the body against infections and diseases. Antibodies are made up of amino acids, which are the building blocks of proteins. Therefore, the correct answer is antibodies because they are derived from amino acids.Rate this question:

Infection with the adult worm
- A.
Taeniasis
- B.
Cysticercosis
- C.
Neurocysticercosis
Correct Answer
A. TaeniasisExplanation
Taeniasis is a parasitic infection caused by the adult tapeworm. It occurs when a person ingests contaminated food or water containing the eggs or larvae of the tapeworm. The adult worm then grows and attaches itself to the intestines, causing symptoms such as abdominal pain, diarrhea, and weight loss. Cysticercosis, on the other hand, is caused by the larvae of the tapeworm and can lead to the formation of cysts in various organs of the body. Neurocysticercosis specifically affects the central nervous system. Therefore, the correct answer is taeniasis because it refers to the infection with the adult worm.Rate this question:

Tissue Infection caused by metacestode or larval stage of taenia solium
- A.
Taeniasis
- B.
Cysticercosis
- C.
Neurocysticercosis
Correct Answer
B. CysticercosisExplanation
Cysticercosis is a tissue infection caused by the metacestode or larval stage of Taenia solium, a tapeworm. It occurs when the eggs of the tapeworm are ingested and the larvae migrate to various tissues in the body. This can lead to the formation of cysts in the muscles, brain, or other organs, causing a range of symptoms depending on the location of the cysts. Neurocysticercosis refers specifically to cysticercosis in the brain. Taeniasis, on the other hand, refers to the infection of the adult tapeworm in the intestines.Rate this question:

Most common parasitic infection of the human CNS
- A.
Taeniasis
- B.
Cysticercosis
- C.
Neurocysticercosis
Correct Answer
C. NeurocysticercosisExplanation
Neurocysticercosis is the most common parasitic infection of the human CNS. It is caused by the larvae of the tapeworm Taenia solium. This infection occurs when a person ingests the eggs of the tapeworm, usually through contaminated food or water. The eggs hatch in the intestines and the larvae can then migrate to various tissues, including the central nervous system. Neurocysticercosis can cause a range of neurological symptoms, including seizures, headaches, and cognitive impairment. It is a significant public health concern in many parts of the world, particularly in areas with poor sanitation and limited access to healthcare.Rate this question:
