Not only did you forget your lunch at home, but on the way to work you slipped and fell into a worm hole and were transported back to 1850. Figuring you may as well make the most of it you decide to go to work at a dairy. Since this is the 19th century there is of course no electricity and so all the milking is done by hand. What disease can you give a cow by hand milking?
- A.
Cold Hand Shudders
- B.
Bovine Mastitis
- C.
Foreplay
- D.
Enzootic Pneumonia
Correct Answer
B. Bovine MastitisExplanation
Bovine Mastitis is a disease that can be transmitted to cows through hand milking. It is an inflammation of the udder caused by bacteria entering the teat canal during the milking process. Since there is no electricity in the 19th century, all milking is done by hand, increasing the risk of transmitting the disease to the cows. Cold Hand Shudders, Foreplay, and Enzootic Pneumonia are unrelated to the act of hand milking and do not pose a risk to cows in this context.Rate this question:

Animals often carry MRSA.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
MRSA stands for Methicillin-resistant Staphylococcus aureus, which is a type of bacteria that is resistant to many antibiotics. While MRSA can be found in humans, it is not commonly carried by animals. It is more often transmitted between humans through direct contact or contaminated surfaces. Therefore, the statement that animals often carry MRSA is false.Rate this question:

If a dog has superficial pyoderma, which part of the skin are infected?
- A.
Stratum corneum
- B.
Hair follicles and epidermis
- C.
Dermis
Correct Answer
B. Hair follicles and epidermisExplanation
Superficial pyoderma refers to a bacterial infection that affects the outermost layer of the skin, including the epidermis and hair follicles. The bacteria invade and multiply within these structures, causing inflammation, redness, and pustules. The infection is limited to the superficial layers of the skin, and does not penetrate into the deeper dermis. Therefore, the correct answer is "Hair follicles and epidermis."Rate this question:

German Shepherds are predisposed to developing which type of skin disease?
Correct Answer
Deep Pyoderma, German Shepherd Deep PyodermaExplanation
German Shepherds are predisposed to developing deep pyoderma, a type of skin disease. Deep pyoderma is characterized by a bacterial infection that affects the deeper layers of the skin, causing inflammation, redness, and the formation of pus-filled lesions. This condition is more common in German Shepherds due to their genetic predisposition and certain factors such as their dense coat and susceptibility to allergies. Prompt diagnosis and treatment are essential to manage deep pyoderma in German Shepherds and prevent further complications.Rate this question:

If a dog has a hot spot, it has surface pyoderma.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A hot spot is a common skin condition in dogs that is characterized by inflamed and infected areas on the skin. Surface pyoderma refers to a bacterial infection of the outer layers of the skin. Since a hot spot is a type of skin infection, it can be considered a form of surface pyoderma. Therefore, the statement is true.Rate this question:

What is the best sample to submit to get a culture and sensitivity for superficial pyoderma?
- A.
Aspirate of unopened pustule
- B.
Swab of draining tract
- C.
Opened pustule sample
Correct Answer
A. Aspirate of unopened pustuleExplanation
The best sample to submit to get a culture and sensitivity for superficial pyoderma is an aspirate of an unopened pustule. This is because an unopened pustule contains the most concentrated and pure sample of the bacterial infection. By aspirating the contents of the pustule, the sample will have a higher chance of yielding accurate results for identifying the causative bacteria and determining the appropriate antibiotic treatment. Swabbing a draining tract or using an opened pustule sample may not provide as reliable or representative of a sample.Rate this question:

What is the medical term for "greasy pig"?
Correct Answer
Exudative Epidermatis of SwineExplanation
Exudative Epidermatis of Swine is the medical term for "greasy pig". This condition is characterized by a greasy, oily appearance of the pig's skin, caused by excessive sebum production. It is a common skin disorder in piglets, typically occurring within the first week of life. The condition is often associated with bacterial infections and can lead to skin inflammation, scabs, and hair loss. Prompt veterinary treatment is necessary to manage the symptoms and prevent further complications.Rate this question:

How old are piglets that are affected by S. hyicus?
- A.
1 month
- B.
5-60 days
- C.
2 weeks
- D.
3-10 days
Correct Answer
B. 5-60 daysExplanation
Piglets that are affected by S. hyicus can be between 5-60 days old. This age range is likely because piglets are most susceptible to the infection during the first few weeks of their lives. S. hyicus is a bacteria that can cause a skin condition called exudative epidermitis, which is more commonly known as greasy pig disease. This disease mainly affects piglets and can result in skin lesions, fever, and poor growth. Therefore, it is important to be aware of the age range during which piglets are most vulnerable to S. hyicus infection.Rate this question:

What is staphage lysate?
- A.
A type of bacterial toxin used for bacterin
- B.
S. aureus lysed by phage used in immune modulation
- C.
Virus given for immune modulation
Correct Answer
B. S. aureus lysed by pHage used in immune modulationExplanation
Staphage lysate is a substance that is created by lysing (breaking open) Staphylococcus aureus bacteria using bacteriophages (viruses that infect bacteria). This lysate is then used for immune modulation, which means it is used to modify or regulate the immune response in the body. By introducing the lysed bacteria into the body, it can help stimulate the immune system and potentially enhance its ability to fight off infections caused by Staphylococcus aureus.Rate this question:
