Type C strains of C. perfringens produce which toxins?
- A.
Alpha only
- B.
Alpha and Beta
- C.
Beta only
- D.
Beta and epsilon
- E.
Just epsilon
Correct Answer
B. Alpha and BetaExplanation
Type C strains of C. perfringens produce both alpha and beta toxins. Alpha toxin is a phospholipase enzyme that disrupts cell membranes, leading to tissue damage and hemolysis. Beta toxin, also known as perfringolysin O, is a pore-forming toxin that causes cell lysis and tissue destruction. These toxins contribute to the pathogenicity of C. perfringens and are responsible for the characteristic symptoms and tissue damage associated with infections caused by type C strains.Rate this question:

C. perfringens type B is found commonly in the USA
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because Clostridium perfringens type B is not commonly found in the USA. C. perfringens type B is actually rare and is primarily associated with enteritis necroticans, also known as pigbel disease, which occurs in certain developing countries. In the USA, C. perfringens type A is the most common type and is responsible for causing foodborne illnesses.Rate this question:

Presence of spores in a fecal sample is indicative of CPAD in dogs.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The presence of spores in a fecal sample is not indicative of CPAD (Canine Parvovirus Enteritis) in dogs. CPAD is a viral infection that affects the gastrointestinal tract of dogs and is not caused by spores. The presence of spores in a fecal sample could indicate the presence of other types of infections or parasites, but not CPAD. Therefore, the statement is false.Rate this question:

Overeating disease of sheep is caused by which strain of C. perfringens?
- A.
Type A
- B.
Type B
- C.
Type C
- D.
Type D
Correct Answer
D. Type DExplanation
Overeating disease of sheep is caused by Type D strain of C. perfringens. This strain produces epsilon toxin, which is responsible for the disease. Type D strain is commonly found in the intestines of healthy sheep, but under certain conditions such as overeating, the bacteria can multiply rapidly and produce toxins that cause severe damage to the intestines. This can lead to symptoms such as sudden death, bloating, and diarrhea in affected sheep. Therefore, Type D strain is the correct answer for the cause of overeating disease in sheep.Rate this question:

Black disease of sheep can be triggered by migration of Fasciola hepatica
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Black disease of sheep is a condition caused by the migration of Fasciola hepatica, a liver fluke parasite. The parasite infects the liver of the sheep and causes necrosis, leading to the characteristic black discoloration of the affected tissue. This disease is commonly seen in areas where liver fluke infestations are prevalent. Therefore, the statement that black disease of sheep can be triggered by the migration of Fasciola hepatica is true.Rate this question:

What is another name for Bacillary hemoglobinuria?
Correct Answer
Red water diseaseExplanation
Bacillary hemoglobinuria is commonly known as Red water disease. This disease is caused by a bacteria called Clostridium haemolyticum, which produces toxins that destroy red blood cells, leading to the presence of blood in the urine. The name "Red water disease" is derived from the characteristic red or dark urine coloration observed in affected animals. This disease primarily affects cattle and can be fatal if left untreated.Rate this question:
- 11.
What is the etiologic agent for Red water disease?
Correct Answer
Clostridium novyi Type D
Clostridium haemolyticumExplanation
The etiologic agents for Red water disease are Clostridium novyi Type D and Clostridium haemolyticum. These bacteria are responsible for causing the disease.Rate this question:

Which organism is responsible for weanling diarrhea of rabbits and antibiotic associated enteritis in adult rabbits?
Correct Answer
Clostridium spiriformeExplanation
Clostridium spiriforme is responsible for weanling diarrhea in rabbits, which is a condition characterized by diarrhea in young rabbits after weaning. It is also the causative agent of antibiotic-associated enteritis in adult rabbits, which is inflammation of the intestines due to the use of antibiotics. Clostridium spiriforme is a bacterium that can cause gastrointestinal issues in rabbits of different ages.Rate this question:
- 13.
What is the etiologic agent of Tyzzer's disease?
Correct Answer
Clostridium piliformeExplanation
Clostridium piliforme is the etiologic agent of Tyzzer's disease. Tyzzer's disease is a bacterial infection that primarily affects animals, particularly rodents and other small mammals. Clostridium piliforme is a gram-negative, spore-forming bacterium that can cause severe gastrointestinal and liver disease in infected animals. It is transmitted through the ingestion of contaminated food or water. The bacterium targets the liver and causes necrotizing hepatitis, leading to symptoms such as diarrhea, lethargy, and death in severe cases. Prompt diagnosis and treatment are crucial to prevent the spread of the infection and minimize its impact on animal populations.Rate this question:
- 14.
What foal age group is normally associated with Tyzzer's disease?
- A.
1-6 weeks
- B.
1-6 months
- C.
1-6 years
Correct Answer
A. 1-6 weeksExplanation
Tyzzer's disease is a bacterial infection that primarily affects young foals. The age group most commonly associated with this disease is 1-6 weeks. During this time, foals are particularly susceptible to the infection due to their immature immune systems. It is important for horse owners and veterinarians to be aware of the age group at risk in order to detect and treat Tyzzer's disease promptly.Rate this question:

Clostridium spp are zoonotic
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Clostridium spp are not zoonotic. Zoonotic diseases are those that can be transmitted between animals and humans. While some species of Clostridium can cause diseases in animals, they are not typically known to be directly transmitted to humans. However, certain toxins produced by Clostridium species can cause illnesses in humans if ingested through contaminated food or wounds. Therefore, it is important to handle and cook food properly to prevent any potential infection from Clostridium spp.Rate this question:

You give an IM injection of Banamine to a horse which later develops an infection at the wound site. Which organism is probably responsible?
Correct Answer
Clostridium septicumExplanation
Clostridium septicum is a gram-positive, anaerobic bacterium that can cause infections at the wound site. It is commonly associated with gas gangrene and can lead to tissue destruction and systemic infection. This bacterium is commonly found in the environment and can enter the body through contaminated wounds. In this case, the horse developed an infection at the injection site after receiving Banamine, suggesting that Clostridium septicum is likely responsible for the infection.Rate this question:

What is another name for Braxy?
Correct Answer
Ovine AbomasitisExplanation
Ovine Abomasitis is another name for Braxy. Braxy is a disease that affects sheep and is characterized by inflammation of the abomasum, which is the fourth compartment of the sheep's stomach. This condition can cause severe abdominal pain, diarrhea, and even death in affected animals. Therefore, Ovine Abomasitis is the correct alternative term for Braxy.Rate this question:
- 18.
Ingestion of frozen or poor quality feed can lead to Braxy
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Ingesting frozen or poor quality feed can lead to Braxy, which is a disease commonly found in sheep. This disease is caused by the consumption of feed that has been frozen or is of low quality. The ingestion of such feed can result in the development of Braxy in sheep. Therefore, the statement "Ingestion of frozen or poor quality feed can lead to Braxy" is true.Rate this question:

- 19.
What organism is the etiologic agent for Braxy?
Correct Answer
Clostridium septicumExplanation
Clostridium septicum is the etiologic agent for Braxy. Braxy is a disease that primarily affects sheep and is characterized by inflammation of the abomasum (the fourth stomach compartment). Clostridium septicum is a gram-positive, anaerobic bacterium that is commonly found in the gastrointestinal tract of animals. It produces toxins that can cause tissue damage and lead to the development of Braxy. Therefore, Clostridium septicum is the correct answer as it is the organism responsible for causing this specific disease.Rate this question:
