secondary ear or sinus infection (usually caused by your normal microbiota that thrive on fluid
and mucus build up due to colds)
2. Lower respiratory infections like bronchitis

Symptoms of strep throat correct answers extremely sore throat, fever, sometimes pus-filled
lesions on tonsils and/or nausea
- sometimes a patient might have strep throat with flu-like symptoms and no sore throat

Treatment for strep throat correct answers antibiotics (ex: penicillin). The presence of S.
pyogenes should be confirmed by testing BEFORE antibiotics are prescribed because it is known
for false negatives and positive

Prevention for strep throat correct answers Hand washing

What are some potential complications related to strep throat? correct answers - scarlet fever
- streptococcal toxic shock syndrome
- rheumatic fever
- glomerulonephritis

Scarlet Fever (Scarlatina) correct answers a disease of certain strains of S. pyogenes that produce
erythrogenic toxin. This disease caused many deaths in children in the 1900s

Symptoms of scarlet fever correct answers red skin rash, high fever (of over 102), and sometimes
a "strawberry" tongue which makes it very difficult to drink or eat and the body becomes very
dehydrated

Streptococcal Toxic Shock Syndrome correct answers a disease when certain strains of S.
pyogenes produces exotoxins that act as super-antigens which cause an inappropriate immune
response that can lead to shock and death

Rheumatic Fever correct answers a disease where the immune responses against S. pyogenes,
attack themselves instead of the microorganism. Is either:
1. joint tissue attack

, 2. heart tissue attack

Rheumatic Fever Joint Tissue Attack correct answers immune system attacks its own joint tissue
and leads to arthritis

Rheumatic Fever Heart Tissue Attack correct answers immune system attacks its own heart
tissue and leads to permanent heart valve damage which causes back flow of blood in the heart

Glomerulonephritis correct answers a disease where the immune responses against S. pyogenes
sometimes causes permanent damage to the kidneys (usually only one though)

Describe influenza immunity correct answers immunity develops to viral spikes (antigens)
during an influenza infection or following a vaccination.

Describe influenza mutation correct answers influenza viruses mutate frequently which changes
the spike antigens and evolution of new strains

Describe the Influenza Strain Naming System correct answers Hemagglutinin (H) and
Neuraminidase (N) are important molecules on the influenza viral surface.
EX: H2N2 (2 H molecular variations and 2 N molecular variations)

Describe the influenza virus in birds, pigs, and humans correct answers 1. some strains found
here can infect species outside of their usual host range
2. different viral strains can exchange genetic information creating a hybrid Influenza strain with
a new mix of genetic material
3. the new mix can result in a hybrid virus that has antigens that are significantly different than
the original
