Ascaris grows to a length of up to
- A.
35 cm
- B.
45 cm
- C.
60 cm
- D.
90 cm
Correct Answer
A. 35 cmExplanation
Ascaris is a type of roundworm that can infect humans. It is known to grow up to a length of 35 cm. This length is considered to be the average size for an adult Ascaris worm. The other options provided (45 cm, 60 cm, and 90 cm) are not accurate as they exceed the typical length of an Ascaris worm. Therefore, the correct answer is 35 cm.Rate this question:

Ascaris lumbricoides infection is more likely to occur in:
- A.
Tropical climates
- B.
Pork eating countries
- C.
Developing countries
- D.
Western countries
Correct Answer
C. Developing countriesExplanation
Ascaris lumbricoides infection is more likely to occur in developing countries. This is because developing countries often lack proper sanitation and hygiene practices, which can lead to the spread of the parasite. Additionally, limited access to healthcare and clean water sources can contribute to the higher prevalence of the infection in these countries. In contrast, western countries generally have better sanitation systems and healthcare facilities, reducing the risk of Ascaris lumbricoides infection.Rate this question:

What is the infective form of Ascaris lumbricoides?
- A.
Unembryonated ova
- B.
Embryonated eggs
- C.
Larvae
- D.
All of the above
Correct Answer
B. Embryonated eggsExplanation
The infective form of Ascaris lumbricoides is the embryonated eggs. These eggs are found in the feces of infected individuals and are capable of surviving in the environment for a long period of time. When ingested by a suitable host, such as a human, the eggs hatch and release larvae that can penetrate the intestinal wall and migrate to various organs, causing infection. This is why the correct answer is embryonated eggs.Rate this question:

These worms are parasites that use your body as a host to mature from larvae or eggs to adult worms.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because there are certain types of worms that can enter the human body and use it as a host to complete their life cycle. These worms start as larvae or eggs and then develop into adult worms inside the body. They rely on the nutrients and environment provided by the host to grow and reproduce. Therefore, the statement accurately describes the parasitic nature of these worms.Rate this question:

What is the common specimen source required to detect Ascaris lumbricoides?
- A.
Sputum
- B.
Faeces
- C.
Food sample
- D.
Both a and b are correct
Correct Answer
D. Both a and b are correctExplanation
Both sputum and feces are correct specimen sources required to detect Ascaris lumbricoides. Ascaris lumbricoides is a parasitic worm that primarily infects the intestines, but can also migrate to the respiratory system. Therefore, to accurately diagnose an infection, samples from both the respiratory system (sputum) and the gastrointestinal system (feces) are necessary. By examining these specimens, the presence of Ascaris eggs or larvae can be detected, confirming the infection.Rate this question:

The main feature that distinguishes fertilized eggs from unfertilized eggs of Ascaris lumbricoides?
- A.
Size
- B.
Color
- C.
Shape
- D.
All of the above
Correct Answer
A. SizeExplanation
Fertilized eggs of Ascaris lumbricoides are larger in size compared to unfertilized eggs. This difference in size is a key characteristic that distinguishes between the two types of eggs.Rate this question:

Female Ascaris worm releases approximately 200 000 - 2 000 000 eggs per day.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because female Ascaris worms are known to release a large number of eggs on a daily basis. The range of 200,000 to 2,000,000 eggs per day is quite substantial, indicating a high reproductive capacity of these worms. This large number of eggs helps ensure the survival and spread of the species.Rate this question:

Ascaris worms are also "warm worms."
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Ascaris worms are not "warm worms." This statement is incorrect. Ascaris worms are actually parasitic roundworms that infect the intestines of humans and animals. They are not warm-blooded organisms themselves. Therefore, the correct answer is False.Rate this question:

What sorts of drugs are used in the treatment against ascariasis?
- A.
Albendazole
- B.
Mebendazole
- C.
Erythromycin
- D.
Anthelmintics
- E.
All a, b, and c are correct
Correct Answer
E. All a, b, and c are correctExplanation
Ascariasis is an infection caused by the parasitic roundworm Ascaris lumbricoides. The drugs used in the treatment of ascariasis are Albendazole and Mebendazole, which are anthelmintics specifically used to kill parasitic worms. Erythromycin, on the other hand, is an antibiotic that is not effective against parasitic infections. Therefore, the correct answer is "All a, b, and c are correct" as Albendazole, Mebendazole, and Anthelmintics (a general term for drugs used to treat worm infections) are all appropriate treatments for ascariasis.Rate this question:

Ascaris spp are commonly contracted by the host via:
- A.
Fecal-oral route
- B.
Respiratory route
- C.
Both A & B
- D.
None of the above
Correct Answer
A. Fecal-oral routeExplanation
Ascaris spp are commonly contracted by the host through the fecal-oral route. This means that the parasite is ingested by the host when they consume food or water contaminated with the eggs or larvae of the parasite. The eggs or larvae then travel through the digestive system and mature into adult worms, causing an infection. The respiratory route is not a common mode of transmission for Ascaris spp.Rate this question:
