Bloodstream Protozoa infections typically cause anemia by destroying red blood cells.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Bloodstream protozoa infections typically cause anemia by destroying red blood cells. This is because protozoa invade and multiply within the red blood cells, leading to their destruction and reducing the number of functional red blood cells. As a result, the body's ability to transport oxygen to tissues is compromised, leading to anemia.Rate this question:

Diagnosis of a parasitic infection is based on
- A.
The toxins they release
- B.
Their cellular components
- C.
Identifying the parasites themselves or their progeny
- D.
None of these
Correct Answer
C. Identifying the parasites themselves or their progenyExplanation
The correct answer is identifying the parasites themselves or their progeny. This is because the diagnosis of a parasitic infection involves directly identifying the parasites or their offspring in the patient's body. This can be done through various methods such as microscopic examination of bodily fluids or tissues, serological tests, or molecular techniques. The presence of parasites or their progeny confirms the diagnosis of a parasitic infection. The other options, toxins they release and their cellular components, may be used to study the characteristics of the parasites but are not the primary method of diagnosis.Rate this question:

Extracellular protozoa are usually spread by a vector.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Extracellular protozoa are not usually spread by a vector. Protozoa are single-celled organisms that can be found in various environments, including in the soil, water, and as parasites in animals. While some protozoa can be transmitted through vectors, such as mosquitoes carrying malaria parasites, the statement specifically refers to extracellular protozoa. These types of protozoa are not typically dependent on vectors for their spread and can be transmitted through direct contact or ingestion of contaminated food or water. Therefore, the correct answer is false.Rate this question:

Flukes are tissue helminths that are not
- A.
Penetrate skin
- B.
Emerge from snails that swim in water
- C.
Mature outside of the venous system
- D.
Lose their tails and change into a form that can enter the bloodstream after they burrow in the skin
Correct Answer
C. Mature outside of the venous systemExplanation
Flukes are tissue helminths that mature outside of the venous system. This means that they do not complete their development inside the blood vessels. Instead, they go through their life cycle outside of the veins, typically in other organs or tissues of the host. This is in contrast to some other parasites that may mature and reproduce within the bloodstream itself.Rate this question:
-
- 7.

Many live in the GI tract but can infect internal organs
- E.
Usually are able to complete life cycle within a single host
- F.
Disease is directly related to the number of parasites acquired
Correct Answer(s)
A. Worms
C. Transmitted by oral ingestion, penetration of broken skin, or arthropod bite
D. Many live in the GI tract but can infect internal organs
F. Disease is directly related to the number of parasites acquiredExplanation
Helminths are worms that can be transmitted through oral ingestion, penetration of broken skin, or arthropod bite. While many of them live in the gastrointestinal (GI) tract, they can also infect internal organs. They usually complete their life cycle within a single host. The severity of the disease caused by helminths is directly related to the number of parasites acquired.Rate this question:

Humans become infected with tapeworms when they eat beef with the eggs that have hatched in the intestines, and vice versa.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because tapeworms can be transmitted to humans through the consumption of beef that is contaminated with the eggs of the tapeworm. When these eggs hatch in the intestines, the tapeworms can then infect humans. Similarly, humans can also transmit tapeworms to animals if they consume contaminated human feces or if they have poor hygiene practices. Therefore, the statement is correct in stating that humans can become infected with tapeworms when they eat beef with the hatched eggs in the intestines, and vice versa.Rate this question:

- A.
Taken up by biting mosquitos
- B.
Spread throughout the body and into the lungs
- C.
Left by biting mosquitos
- D.
No longer need to reproduce in red blood cells
Correct Answer
A. Taken up by biting mosquitosExplanation
The correct answer is "taken up by biting mosquitos". This is because the passage states that some of the parasites in the bloodstream are able to reproduce sexually. These parasites are then taken up by biting mosquitos, which allows them to spread and infect new hosts. Therefore, this option accurately describes the next step in the life cycle of the malaria parasite.Rate this question:

In the mosquito, Malaria goes to the salivary glands as __________ during the infectious stage and then enters the liver cells of the host.
- A.
Sporozoites
- B.
Plasmodium
- C.
Spores
- D.
Merozoites
Correct Answer
A. SporozoitesExplanation
During the infectious stage of Malaria in mosquitoes, the Malaria parasite, Plasmodium, goes to the salivary glands as sporozoites. These sporozoites are then injected into the bloodstream of the host when the mosquito bites, and they eventually enter the liver cells where they multiply and cause the disease.Rate this question:

Intestinal Helminths are acquired by
- A.
Ingestion of eggs
- B.
Direct penetration of larvae through skin
- C.
Both
- D.
Neither
Correct Answer
C. BothExplanation
Intestinal helminths can be acquired through both ingestion of eggs and direct penetration of larvae through the skin. Some helminths, such as roundworms and tapeworms, release eggs in the host's feces, which can contaminate the environment and be ingested by another host. On the other hand, certain helminths, like hookworms, have larvae that can penetrate the skin of humans when they come into contact with contaminated soil or water. Therefore, both routes of acquisition are possible for intestinal helminths.Rate this question:
-
- 13.
Intestinal Helminths are often asymptomatic unless the worm burden is very large.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Intestinal helminths are parasitic worms that infect the intestines. This statement suggests that these infections usually do not cause noticeable symptoms unless there is a high number of worms present in the body. This is because a small number of worms may not cause significant damage or provoke a noticeable immune response. However, when the worm burden is very large, it can lead to symptoms such as abdominal pain, diarrhea, weight loss, and anemia. Therefore, the statement is true.Rate this question:
-
- 14.
Intestinal Helminths can cause malnutrition in the host.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Intestinal helminths, which are parasitic worms that reside in the intestines, can indeed cause malnutrition in the host. These worms feed on the nutrients present in the host's intestines, leading to a reduced absorption of essential nutrients such as vitamins, minerals, and proteins. As a result, the host may suffer from malnutrition, which can have detrimental effects on their overall health and well-being. Therefore, the statement "Intestinal Helminths can cause malnutrition in the host" is true.Rate this question:
-
- 15.
Intestinal helminths reproduce asexually.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Intestinal helminths do not reproduce asexually. They are multicellular parasites that reproduce sexually. They have complex life cycles that involve both sexual and asexual reproduction stages. In their sexual reproduction stage, they produce eggs that are released into the environment through the feces of the infected host. These eggs then develop into larvae, which can infect new hosts and continue the life cycle. Therefore, the correct answer is false.Rate this question:
-
- 16.
Intracellular protozoa are usually spread by the fecal oral route.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Intracellular protozoa are usually spread by other means, such as through vectors like mosquitoes or ticks, or through direct contact with infected bodily fluids. The fecal-oral route is more commonly associated with the spread of certain bacteria and viruses. Therefore, the statement that intracellular protozoa are usually spread by the fecal-oral route is false.Rate this question:
-
- 17.
Most protozoa have extracellular stages during the lifecycle. Most protozoa have extracellular stages during the lifecycle.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because most protozoa do not have extracellular stages during their lifecycle. Protozoa are single-celled organisms that typically live and carry out all their functions within a single cell. They do not have distinct extracellular stages like some other organisms, such as parasites or fungi. Therefore, the correct answer is false.Rate this question:

Most tapeworm infections are asymptomatic. However, they can lead to vitamin deficiency and anemia and can cause severe CNS manifestations.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Tapeworm infections are often symptomless, meaning that individuals infected with tapeworms may not experience any noticeable symptoms. However, these infections can still have negative effects on the body. Tapeworms can lead to vitamin deficiency and anemia, which can cause weakness and fatigue. Additionally, severe central nervous system (CNS) manifestations can occur as a result of tapeworm infections, potentially leading to neurological symptoms such as seizures or cognitive impairment. Therefore, the statement that most tapeworm infections can lead to vitamin deficiency, anemia, and severe CNS manifestations is true.Rate this question:
-
- 19.
Parasite infection is short and only occurs once.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Parasite infection is not always short and can occur multiple times. Some parasites have complex life cycles and can persist in the host for extended periods, causing chronic infections. Additionally, certain parasites can be transmitted through various routes, such as contaminated food or water, making reinfection possible. Therefore, the statement that parasite infection is short and only occurs once is incorrect.Rate this question:
-
- 20.
Parasites require only one type of host to complete their lifecycle.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Parasites typically require more than one type of host to complete their lifecycle. They often have complex life cycles that involve multiple hosts, such as intermediate hosts and definitive hosts. These hosts provide different environments or resources that the parasite needs at different stages of its life. Therefore, the statement that parasites require only one type of host to complete their lifecycle is false.Rate this question:
