Understanding Streptococcus Pyogenes and Its Complications

1. How does pyogensis work?

3. Pyogensis primarily affects the digestive system.

1. Pyogensis is caused by a viral infection.

2. The process of pyogensis involves the multiplication of fungi in the lungs.

Pyogensis refers specifically to the process described in the correct answer, involving the streptococcal bacteria entering the upper respiratory tract and causing symptoms like inflammation and swollen lymph nodes.

Explanation

Pyogensis refers specifically to the process described in the correct answer, involving the streptococcal bacteria entering the upper respiratory tract and causing symptoms like inflammation and swollen lymph nodes.

2. What 3 complications can occur after an untreated strep infection?

1. bronchitis 2. appendicitis 3. pneumonia

1. scarlet fever 2. glomerulonephritis 3. rhumatic fever

The correct complications that can occur after an untreated strep infection are scarlet fever, glomerulonephritis, and rheumatic fever. Bronchitis, appendicitis, and pneumonia are not directly associated with untreated strep infections.

Explanation

The correct complications that can occur after an untreated strep infection are scarlet fever, glomerulonephritis, and rheumatic fever. Bronchitis, appendicitis, and pneumonia are not directly associated with untreated strep infections.

3. What is scarlet fever?

An allergic reaction to scarlet-colored food dye.

A form of feverish rash caused by excessive exposure to sunlight.

A type of fever caused by exposure to scarlet-colored objects.

Scarlet fever is a bacterial infection caused by certain strains of streptococcal bacteria that result in strep throat symptoms, skin rash, pink bony rash, strawberry tongue, and inflammation. It is not related to scarlet-colored food dye, objects, or excessive sunlight exposure.

Explanation

Scarlet fever is a bacterial infection caused by certain strains of streptococcal bacteria that result in strep throat symptoms, skin rash, pink bony rash, strawberry tongue, and inflammation. It is not related to scarlet-colored food dye, objects, or excessive sunlight exposure.

4. What is glomerulonephritis?

Inflammation of the liver

A respiratory infection

A type of bone cancer

Glomerulonephritis is a kidney disease characterized by inflammation in the glomeruli due to immune complexes. It is not related to the liver, bone cancer, or respiratory infections.

Explanation

Glomerulonephritis is a kidney disease characterized by inflammation in the glomeruli due to immune complexes. It is not related to the liver, bone cancer, or respiratory infections.

5. What is the cause of Rheumatic fever?

Environmental toxins

Genetic mutation

Autoimmune disease- the antibodies formed against strep proteins cross-react with antigens found in heart and joint tissues

Viral infection

Rheumatic fever is caused by an autoimmune response where antibodies mistakenly target heart and joint tissues due to cross-reaction with strep proteins.

Explanation

Rheumatic fever is caused by an autoimmune response where antibodies mistakenly target heart and joint tissues due to cross-reaction with strep proteins.

6. What are some important facts about Streptococcus pyogenes?

- Disease is chronic and incurable

- Treating with antibiotics is not effective in controlling the spread of the disease

- Immunity to re-infection is permanent after first exposure

Streptococcus pyogenes is usually self-limiting and does not provide immunity upon recovery. Treatment with antibiotics is necessary to prevent complications and further spread.

Streptococcus pyogenes is usually self-limiting and does not provide immunity upon recovery. Treatment with antibiotics is necessary to prevent complications and further spread.
