Different Types Of Parasitology Quiz

Explanation
Ancylostoma duodenale is a parasitic worm that causes Wakana Disease. This disease is also known as hookworm infection and is caused by the infestation of the small intestine by the Ancylostoma duodenale worm. The worm attaches itself to the intestinal wall and feeds on the host's blood, leading to symptoms such as abdominal pain, diarrhea, anemia, and fatigue. Therefore, Ancylostoma duodenale is the correct answer as it is the specific cause of Wakana Disease.

Explanation
Strongyloides stercoralis is a type of parasitic worm that is known to reproduce through parthenogenesis, which means that the female worms are capable of reproducing without the need for fertilization by males. This reproductive strategy allows the female worms to produce offspring without the need for a mate, which can be advantageous in certain environments or situations where males may be scarce or unavailable.

Explanation
This answer refers to a parasitic cycle, which is a specific type of cycle where the rhabditiform larva develops into filariform larvae while in the intestines. In a parasitic cycle, the larva goes through specific stages and transformations while inside the host's intestines, ultimately developing into a different form. This cycle is characteristic of certain parasites that have complex life cycles involving multiple hosts and stages of development.

Explanation
Strongyloides stercoralis is a parasitic roundworm that can cause a gastrointestinal infection known as Cochin China or Vietnam Diarrhea. This infection is commonly found in tropical and subtropical regions, including Vietnam. The parasite is transmitted through contact with contaminated soil or water, usually through bare feet. Once inside the body, the larvae of Strongyloides stercoralis can migrate to the intestines and cause symptoms such as diarrhea, abdominal pain, and weight loss. Proper hygiene and sanitation practices, such as wearing shoes and avoiding contaminated water sources, can help prevent the transmission of this parasite.

Explanation
Anisakis spp is a type of parasitic worm commonly found in fish. These worms can infect humans who consume raw or undercooked fish, causing a condition known as anisakiasis. Symptoms of anisakiasis include abdominal pain, nausea, vomiting, and diarrhea. Therefore, the presence of Anisakis spp in fishes indicates a potential health risk for individuals who consume these fishes without proper cooking or freezing.

Explanation
Toxocara canis is the scientific name for the roundworm that commonly infects dogs. This parasite is found in the intestines of infected dogs and can be transmitted to humans through contact with contaminated soil or feces. It can cause a condition known as toxocariasis in humans, leading to symptoms such as fever, cough, abdominal pain, and even organ damage. Therefore, toxocara canis is the correct answer as it accurately identifies the specific roundworm species mentioned in the question.

Explanation
Ascaris lumbricoides is a type of human roundworm that infects the intestines. It is the most common intestinal parasite in humans, particularly in areas with poor sanitation. Ascaris lumbricoides can be transmitted through the ingestion of contaminated food or water that contains the eggs of the parasite. Once inside the body, the eggs hatch in the intestines and the larvae migrate to the lungs, where they are coughed up and swallowed back into the intestines. The adult worms then grow and reproduce, causing symptoms such as abdominal pain, diarrhea, and malnutrition. Treatment typically involves medication to kill the worms and improve the patient's condition.

Explanation
Trichuris trichiura, commonly known as the human whipworm, is the correct answer. This parasitic roundworm infects the large intestine of humans and causes a condition called trichuriasis. The name "whipworm" comes from the whip-like shape of the worm's body. It is transmitted through ingestion of eggs present in contaminated food, water, or soil. Symptoms of trichuriasis include abdominal pain, diarrhea, and anemia. Treatment typically involves the use of anthelmintic medications to kill the worms and alleviate symptoms.

Explanation
Ancylostoma dudodenale is a type of hookworm that is known for its teeth. Hookworms are parasitic worms that attach themselves to the lining of the small intestine and feed on the host's blood. Ancylostoma dudodenale is one of the species of hookworm that can infect humans. It has sharp teeth that it uses to attach itself to the intestinal wall and feed on blood. This characteristic distinguishes Ancylostoma dudodenale from other species of hookworms.

Explanation
The given answer, "Anisakis spp," suggests that the first case described in the Netherlands is related to an infection caused by Anisakis spp. Anisakis spp is a genus of parasitic nematodes (roundworms) that can infect humans when they consume raw or undercooked seafood containing the larvae of these worms. These larvae can cause a condition known as anisakiasis, which typically manifests as gastrointestinal symptoms such as abdominal pain, nausea, and vomiting. Therefore, it can be inferred that the first case described in the Netherlands involves an individual who likely consumed contaminated seafood and subsequently developed anisakiasis.

Explanation
Toxocara cati is the scientific name for the feline roundworm. This parasitic worm commonly infects cats and can also be transmitted to humans. It can cause various health issues in both cats and humans, including gastrointestinal problems, respiratory issues, and even blindness. Therefore, toxocara cati is the correct answer as it accurately identifies the specific parasite being referred to in the question.

Explanation
Toxocara is suggested as the correct answer because it is similar to a. lumbricodes but smaller in size, about a quarter to half its size. The given information implies that there is a species similar to a. lumbricodes but smaller, and toxocara fits this description.

Explanation
Trichinella spiralis is a parasitic worm that causes trichinosis in humans. One of the key characteristics of this parasite is that its larvae are encysted in the striated muscles of the host. This means that the larvae form protective cysts within the muscle tissue, allowing them to survive and develop. This is an important adaptation for the parasite as it enables the larvae to persist in the host for an extended period of time and also facilitates their transmission to new hosts when the infected muscle tissue is consumed.

Explanation
Ascaris lumbricoides is a parasitic worm that causes a condition known as wormball. This worm infects the intestines of humans and can cause symptoms such as abdominal pain, diarrhea, and weight loss. It is commonly found in areas with poor sanitation and can be transmitted through contaminated food or water. The presence of Ascaris lumbricoides in the body can lead to the formation of wormballs, which are clumps of worms tangled together in the intestines. These wormballs can cause blockages and other complications in the digestive system.

Explanation
Ascaris lumbricoides is a parasitic roundworm that infects the human intestines. It is characterized by having trilobate lips, which means its lips are divided into three lobes. This feature is distinct and helps to identify Ascaris lumbricoides from other parasites.

Explanation
The correct answer is "filariform larvae." Filariform larvae are the infective stage of hookworm and Strongyloides. These larvae are able to penetrate the skin of a host and enter the bloodstream, where they can travel to different organs and cause infection. This stage is important in the life cycle of these parasites as it allows them to infect a new host and continue their life cycle.

Explanation
The Harada Mori technique is a diagnostic method used to distinguish between Strongyloides and hookworm infections. It involves collecting a stool sample and using a special solution to culture the larvae present in the sample. The larvae of Strongyloides and hookworm have distinct characteristics that can be observed under a microscope, allowing for accurate identification of the parasite causing the infection. This technique is particularly useful in regions where both parasites are prevalent and can help guide appropriate treatment for the patient.

Explanation
Ascaris lumbricoides is the largest of all adult intestinal roundworms. This parasitic worm commonly infects humans through the ingestion of contaminated food or water. Once inside the body, the worms can grow up to 35 centimeters in length and live in the intestines, causing symptoms such as abdominal pain, diarrhea, and malnutrition. Due to its size and prevalence, Ascaris lumbricoides is considered the largest and most common intestinal roundworm found in adults.

Explanation
Enterobius vermicularis, also known as pinworm, is considered the most infective helminth in the world. It is a common intestinal parasite that primarily affects children. The infection occurs when individuals ingest the eggs of the parasite, which then hatch in the intestines and mature into adult worms. The female worms migrate to the anal area at night to lay their eggs, causing intense itching. The eggs are easily transmitted to others through direct contact or contaminated surfaces. Due to its high transmission rate and prevalence, Enterobius vermicularis is considered the most infective helminth worldwide.

Explanation
Enterobius vermicularis, also known as human pinworm or seatworm, is a parasitic worm that commonly infects the human intestines. It is the most common worm infection in humans, particularly affecting children. The female pinworm lays eggs around the anus, causing intense itching and discomfort. The eggs can easily spread to other surfaces and objects, leading to further transmission. Proper hygiene practices, such as handwashing and maintaining a clean living environment, are crucial in preventing and controlling the spread of enterobius vermicularis infections.

Explanation
The Baermann technique is a diagnostic method used for the detection of Strongyloides, a parasitic worm. This technique involves placing a fecal sample in a funnel with a filter at the bottom and allowing it to sit for a period of time. As the sample sits, the larvae of the Strongyloides will migrate out of the feces and collect at the bottom of the funnel. The larvae can then be collected and examined under a microscope for identification. This technique is considered to be a reliable and sensitive method for diagnosing Strongyloides infections.

Explanation
Baylisascaris procyonis is a common ascarid of raccoons. This parasitic roundworm can infect humans and other animals if they accidentally ingest the eggs found in raccoon feces. Once inside the body, the larvae migrate through different organs, causing damage and potentially severe health problems. It is important to be cautious when handling raccoon feces and to practice good hygiene to prevent infection.
