Sporotrichosis can exist in what forms?
- A.
Cutaneous
- B.
Lymphocutaneus
- C.
Disseminated
- D.
Pumonary
- E.
Cardiac
Correct Answer(s)
A. Cutaneous
B. Lymphocutaneus
C. DisseminatedExplanation
Sporotrichosis can exist in different forms, including cutaneous, lymphocutaneous, and disseminated. Cutaneous sporotrichosis refers to the infection of the skin, typically resulting from direct inoculation of the fungus. Lymphocutaneous sporotrichosis involves the spread of the infection from the initial site to the lymphatic system. Disseminated sporotrichosis occurs when the infection spreads beyond the skin and lymphatic system to other organs and tissues in the body. The answer provided includes all three forms of sporotrichosis.Rate this question:

Rose-gardener's disease is caused by what organism?
Correct Answer(s)
Sporothrix schenckiiExplanation
Rose-gardener's disease, also known as sporotrichosis, is caused by the organism Sporothrix schenckii. This fungus is commonly found in soil, plants, and decaying vegetation. It typically enters the body through cuts or punctures in the skin when handling contaminated plant material, such as roses. Once inside, the fungus can cause localized skin lesions or spread to other parts of the body, including the lungs and bones. Prompt diagnosis and treatment with antifungal medications are essential to prevent complications and promote recovery.Rate this question:

Sporotrichosis can be told apart from Histoplasmosis because Histoplasma develops cigar shaped yeasts.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Sporotrichosis and Histoplasmosis are both fungal infections, but they can be differentiated based on their characteristic features. Sporotrichosis is caused by the fungus Sporothrix, which typically forms nodules or ulcers on the skin. In contrast, Histoplasmosis is caused by the fungus Histoplasma, which primarily affects the lungs and can cause flu-like symptoms. Histoplasma does not develop cigar-shaped yeasts. Therefore, the statement that Histoplasma develops cigar-shaped yeasts is false.Rate this question:

Only feline sporotrichosis is zoonotic
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Feline sporotrichosis is a fungal infection that can be transmitted from animals to humans, making it a zoonotic disease. This means that humans can get infected by coming into contact with infected cats or their bodily fluids. Other forms of sporotrichosis, such as those found in plants or soil, are not zoonotic and do not pose a risk to humans. Therefore, the statement that only feline sporotrichosis is zoonotic is true.Rate this question:

One way to diagnose Phaeohyphomycosis is to look for what characteristic of the hyphae?
- A.
Non-septate
- B.
Pigmentation
- C.
Sulfur granules
Correct Answer
B. PigmentationExplanation
Phaeohyphomycosis is a fungal infection characterized by the presence of pigmented hyphae. These hyphae appear brown or black due to the production of melanin, a pigment. Therefore, looking for pigmentation in the hyphae is a reliable way to diagnose Phaeohyphomycosis. Non-septate refers to hyphae without cross-walls, which is not specific to this infection. Sulfur granules are associated with another type of infection called actinomycosis and are not related to Phaeohyphomycosis.Rate this question:

Which genus of Phaeohyphomycosis causing fungi is known to be neurotropic?
Correct Answer
CladosporiumExplanation
Cladosporium is a genus of fungi known to cause Phaeohyphomycosis, a rare fungal infection that affects the skin, nails, and occasionally the respiratory tract. While Phaeohyphomycosis can affect various parts of the body, Cladosporium is specifically known to be neurotropic, meaning it has a tendency to invade and affect the nervous system. This can lead to neurological symptoms and complications in individuals infected with this fungus.Rate this question:

Chromoblastomycosis can be told apart from Phaeohyphomycosis because the former looks like what?
- A.
Hyphae
- B.
Dark pigmented, sclerotic bodies
- C.
Firm nodules
- D.
Pustules
Correct Answer
B. Dark pigmented, sclerotic bodiesExplanation
Chromoblastomycosis can be distinguished from Phaeohyphomycosis based on the appearance of dark pigmented, sclerotic bodies. These bodies are characteristic of chromoblastomycosis and are not typically seen in Phaeohyphomycosis. The presence of these dark pigmented, sclerotic bodies helps in differentiating between the two conditions.Rate this question:

Canine pythiosis usually occurs as an enteritis
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Canine pythiosis is a disease caused by a waterborne fungus-like organism called Pythium insidiosum. It primarily affects the gastrointestinal tract, causing enteritis or inflammation of the intestines. This inflammation can lead to symptoms such as diarrhea, vomiting, weight loss, and abdominal pain in affected dogs. Therefore, the statement that canine pythiosis usually occurs as an enteritis is true, as it is the most common manifestation of the disease in dogs.Rate this question:

What is another differential diagnosis for Pythium/Lagenidium type lesions?
Correct Answer
ZygomycosisExplanation
Zygomycosis is suggested as another possible differential diagnosis for Pythium/Lagenidium type lesions. Zygomycosis is a fungal infection caused by Zygomycetes fungi, which can lead to tissue necrosis and invasive disease. The symptoms and clinical presentation of Zygomycosis can resemble those of Pythium/Lagenidium infections, making it a potential alternative diagnosis to consider.Rate this question:

What is the name for a mycetoma composed of fungi?
Correct Answer
Eumycotic mycetoma
EumycoticExplanation
The correct answer is "Eumycotic mycetoma". Eumycotic mycetoma refers to a type of mycetoma that is composed of fungi. Mycetoma is a chronic infection that affects the skin, subcutaneous tissue, and sometimes bones. It is characterized by the formation of granules or grains, which can be caused by different types of microorganisms, including bacteria, fungi, and actinomycetes. Eumycotic mycetoma specifically refers to cases where the causative agent is a fungus.Rate this question:
