Screening test for Leprosy (Hansen's Disease)?
Explanation
The Lepromin skin test is a screening test for Leprosy (Hansen's Disease). This test involves injecting a small amount of lepromin, a protein derived from the bacteria that causes leprosy, into the skin. The test is then observed for any reaction or swelling at the injection site. A positive reaction indicates exposure to the bacteria and suggests a possible infection with leprosy. However, it is important to note that this test is not definitive and should be used in conjunction with other diagnostic methods for a conclusive diagnosis.Rate this question:
- 13.
Tumor like growth on skin_________
Explanation
Lepromas are tumor-like growths that occur on the skin. They are a characteristic feature of leprosy, a chronic infectious disease caused by the bacteria Mycobacterium leprae. Lepromas typically appear as raised, reddish-brown nodules on the skin, particularly on the face, ears, and extremities. They can cause disfigurement and nerve damage if left untreated. Lepromas are one of the clinical manifestations of leprosy and are used as a diagnostic criterion for the disease.Rate this question:
- 14.
Has affinity for Schwann Cells which surround nerve axons.
Explanation
M. leprae has an affinity for Schwann Cells because it is the bacterium responsible for causing leprosy, a chronic infectious disease that primarily affects the skin and nerves. Schwann Cells are the cells that form the myelin sheath around nerve axons, providing insulation and support. M. leprae specifically targets these cells, leading to nerve damage and the characteristic symptoms of leprosy, such as loss of sensation, muscle weakness, and skin lesions.Rate this question:

_______________________diseases are acquired in a health care setting.
Explanation
Nosocomial diseases are acquired in a healthcare setting. This means that individuals who are admitted to hospitals or other healthcare facilities can contract these diseases during their stay. The term "nosocomial" specifically refers to infections that are not present or incubating prior to admission, but are acquired within the healthcare environment. These infections can be caused by various factors such as contaminated medical equipment, poor hand hygiene practices, or the presence of drug-resistant bacteria. Preventive measures such as proper disinfection protocols and adherence to infection control practices are crucial in reducing the risk of nosocomial infections.Rate this question:

The action of Botulinum Toxin from C. botulinum results is: Flacid Paralysis. Botulinum toxin blocks release of A inhibiting contraction.
-
True
-
False
Correct Answer
A. TrueExplanation
Botulinum toxin, produced by the bacteria Clostridium botulinum, causes flaccid paralysis. It achieves this by blocking the release of acetylcholine, a neurotransmitter that stimulates muscle contraction. By inhibiting the release of acetylcholine, botulinum toxin prevents muscle contraction, leading to flaccid paralysis. Therefore, the statement "Botulinum toxin blocks release of A inhibiting contraction" is true.Rate this question:

Neisseria gonorrhea Chlamydia trachomatis cause blindness in newborn children passing it through birth canal.
-
True
-
False
Correct Answer
A. TrueExplanation
Both Neisseria gonorrhea and Chlamydia trachomatis can cause blindness in newborn children when passed through the birth canal. These sexually transmitted infections can infect the eyes of the baby during delivery, leading to a condition called neonatal conjunctivitis or ophthalmia neonatorum. If left untreated, this infection can result in severe eye damage and potentially permanent blindness. Therefore, it is crucial for pregnant women to receive appropriate prenatal care and for newborns to receive prompt medical attention to prevent and treat these infections.Rate this question:

Protective Barrier: Epidermis, Keratin, Acid mantle, Salt (sweat)
-
True
-
False
Correct Answer
A. TrueExplanation
The given answer is true because all the options listed (epidermis, keratin, acid mantle, and salt) contribute to the protective barrier of the body. The epidermis is the outermost layer of the skin, which acts as a physical barrier against pathogens and harmful substances. Keratin is a protein found in the skin, hair, and nails, providing strength and protection. The acid mantle is a thin, slightly acidic film on the skin's surface that helps prevent bacterial growth. Salt, present in sweat, also has antimicrobial properties that help protect the body from infections. Therefore, all these components contribute to the protective barrier of the body.Rate this question:

Poor oral hygiene leads to increased subgingival plaque which can be populated by bacteria.
-
True
-
False
Correct Answer
A. TrueExplanation
Poor oral hygiene refers to the lack of proper care and maintenance of the mouth, including brushing and flossing regularly. When oral hygiene is poor, it allows for the accumulation of plaque, a sticky film of bacteria that forms on the teeth and gums. Subgingival plaque specifically refers to the plaque that accumulates below the gum line. This plaque provides an ideal environment for bacteria to thrive and multiply, leading to various oral health problems such as gum disease and tooth decay. Therefore, it is true that poor oral hygiene can lead to increased subgingival plaque populated by bacteria.Rate this question:
