Roundworms (ascarids)
Correct Answer
A. Parascaris Equorum
Explanation
Parascaris equorum is a type of roundworm that commonly infects horses. It is a large, white worm that can grow up to 40 cm in length. These worms live in the small intestine of horses and can cause a range of health issues, including weight loss, poor growth, and colic. They are transmitted through ingestion of contaminated food or water, and their eggs can survive in the environment for long periods of time. Regular deworming and good hygiene practices are essential in preventing and controlling Parascaris equorum infections in horses.
2.
Have a life cycle of
Correct Answer
B. 10 - 12 weeks
Explanation
The correct answer is 10-12 weeks because this is the most appropriate time frame for a life cycle. It is neither too short nor too long, allowing for the necessary stages of growth and development to occur. A life cycle of 8-10 weeks might be too short for complete maturation, while a life cycle of 12-14 weeks might be too long and could result in unnecessary delays or inefficiencies. Therefore, 10-12 weeks strikes a balance and is the most reasonable option.
3.
Effects
Correct Answer
A. Young horses
4.
Found in the
Correct Answer
C. Small intestine
Explanation
The small intestine is the correct answer because it is the primary site for digestion and absorption of nutrients in the body. It is a long, coiled tube located between the stomach and large intestine. The small intestine plays a crucial role in breaking down food into smaller molecules, such as carbohydrates, proteins, and fats, which can be absorbed into the bloodstream. It has a large surface area due to its numerous folds and finger-like projections called villi, which increase the absorption capacity. Therefore, the small intestine is the main organ responsible for nutrient absorption in the digestive system.
5.
Cause
Correct Answer
A. Respiratory signs
Explanation
The correct answer is "Respiratory signs" because the presence of respiratory symptoms such as coughing, sneezing, nasal discharge, or difficulty breathing can indicate an infection or inflammation in the respiratory system. These signs are commonly associated with respiratory diseases like strangles, which is a highly contagious bacterial infection in horses. Lameness, on the other hand, refers to an abnormality or difficulty in movement and is not directly related to respiratory signs.
6.
Adults still carry the parasitic egg but it does not develop.
Correct Answer
A. True
Explanation
Adults still carry the parasitic egg but it does not develop. This statement suggests that while adults may have the parasitic egg, it does not go through the process of development. This implies that the egg remains in a dormant state or is somehow prevented from hatching or growing into a fully formed parasite. Therefore, the answer "True" indicates that the statement is correct and adults do carry the parasitic egg without it developing.
7.
Small Redworms
Correct Answer
B. Cyathostomes spp.
Explanation
The given options are names of different types of worms. "Cyathostomes spp." refers to a group of small redworms that are commonly found in horses. They are a major cause of parasitic infections in horses and can cause various health issues. Therefore, the correct answer is Cyathostomes spp.
8.
Small redworms have a life cycle of
Correct Answer
A. 5 - 18 weeks
Explanation
Small redworms have a life cycle of 5-18 weeks because this is the typical duration for them to complete their life cycle from egg to adult. During this time, the worms go through several stages of development, including hatching from eggs, growing into larvae, and maturing into adult worms. The specific length of the life cycle can vary depending on various factors such as temperature and environmental conditions.
9.
Cyathostomes have the ability to enter a period of hypobiosis. Which can last 4months - 2.5 years. What is meant by hypobiosis?
Correct Answer
B. Arrested larval development
Explanation
Hypobiosis refers to the state of arrested larval development in an organism. In the case of cyathostomes, they have the ability to enter this state, where their larval development is halted. This period of arrested development can last for a significant amount of time, ranging from 4 months to 2.5 years. During this time, the larvae remain dormant and do not progress in their development. This allows them to survive in unfavorable conditions and wait for more favorable conditions to resume their development.
10.
When encysted, protected from most anthelmintic administration.
Correct Answer
A. True
Explanation
When an organism is encysted, it is surrounded by a protective cyst or casing. This cyst provides a barrier that can make it difficult for anthelmintic medications to effectively reach and eliminate the organism. Therefore, when an organism is in an encysted state, it is indeed protected from most anthelmintic administration.
11.
Which one of these could be used to treat cyathostomes?
Correct Answer
B. Panacur Guard
Explanation
Panacur Guard could be used to treat cyathostomes.
12.
And what drug is used in Panacur guard
Correct Answer
B. Benzimidazole
Explanation
Benzimidazole is the drug used in Panacur guard. This drug belongs to a class of anthelmintic medications that are effective against a wide range of parasites. It works by disrupting the reproductive process of the parasites, leading to their death. Benzimidazole is commonly used in the treatment of various parasitic infections in animals, including gastrointestinal worms. Therefore, it is the correct answer for the drug used in Panacur guard.
13.
What is the problem with using BZDs?
14.
Cyathostomes can cause
Correct Answer
B. Larval Cyathostomosis
Explanation
Larval Cyathostomosis is caused by Cyathostomes. This condition refers to the infection of the larval stage of these parasites in the intestines of horses. It can lead to symptoms such as weight loss, diarrhea, colic, and even death in severe cases. Selenium toxicity and Selenium Cyathostomiosis are not recognized conditions caused by Cyathostomes, making them incorrect answers.
15.
Large Redworms.
Correct Answer
A. Strongylus spp.
Explanation
The correct answer is Strongylus spp. Strongylus spp. refers to a group of large redworms that commonly infect horses. These parasites can cause significant damage to the horse's gastrointestinal tract, leading to weight loss, poor appetite, and diarrhea. They can also migrate to other organs, causing further complications. Therefore, it is important for horse owners to regularly deworm their animals and practice good pasture management to prevent the spread of these parasites.
16.
Redworms have a life cycle of
Correct Answer
C. 6 - 11 months
Explanation
Redworms have a life cycle of 6 - 11 months. This means that from the time they hatch from eggs to the time they reach adulthood and reproduce, it takes them between 6 and 11 months. This information is important for those who are interested in raising redworms for composting or other purposes, as it gives them an idea of how long they can expect to have the worms in their care before they complete their life cycle.
17.

A. Ivermectin
B. Pyrantel
C. Benzimiadozoles
E. Moxidectin
Explanation
The large redworms can be controlled by using Ivermectin, Pyrantel, Benzimiadozoles, and Moxidectin. These medications are effective in treating and eliminating the infestation of large redworms in the body.
19.
Cestodes have a direct life cycle.
Correct Answer
B. False
Explanation
Cestodes, also known as tapeworms, have an indirect life cycle. This means that they require an intermediate host to complete their life cycle. The eggs of cestodes are typically ingested by an intermediate host, such as a flea or a small mammal, where they develop into larvae. The larvae then infect the definitive host, usually a larger animal or human, where they mature into adult tapeworms. Therefore, the correct answer is false.
20.
Cestodes. __________________ ________________ are passed in the faeces.
Correct Answer
Small eggs
Mature segments
Immature segments
Millions of eggs
Explanation
Cestodes are a type of parasitic worms that live in the intestines of animals, including humans. These worms reproduce by producing eggs, which are then passed out of the host's body through their feces. The correct answer options, "Small eggs," "Mature segments," "Immature segments," and "Millions of eggs," all describe different stages or characteristics of the cestodes and their reproductive process.
21.
The mature segments are passed in the faeces. Releasing eggs into the environment.
Correct Answer
A. True
Explanation
The statement is true because mature segments of a parasite are typically passed out of the host's body through feces. These segments contain eggs that are released into the environment, allowing the parasite's life cycle to continue.
22.
Tapeworms can be treated with:
Correct Answer(s)
B. Pyrantel
D. Praziquantel
Explanation
Pyrantel and Praziquantel are both effective treatments for tapeworms. Pyrantel works by paralyzing the worms, causing them to detach from the intestinal wall and be eliminated from the body. Praziquantel, on the other hand, works by causing severe muscle spasms in the worms, leading to their paralysis and subsequent elimination. Using both medications together can provide a more comprehensive treatment approach, targeting different aspects of the tapeworm's life cycle and ensuring a higher success rate in eradicating the infection.
