Folliculitis
Diagnosis and treatment
Diagnosis: isolated Gram + clusters in pus
Treatment: antibiotics
29
Staph Scalded Skin Syndrome is caused by...
S. aureus with exfoliative toxin; type of toxemia since it's in the blood
30
Staph scalded skin syndrome transmission, diagnosis, and treatment
Transmission: person-to-person
Diagnosis: physical traits (peeling, sloughing of skin)
Treatment: antibiotics
31
Impetigo is caused by...
Erysipelas is caused by...
Impetigo: S. aureus and/or streptococcus pyogenes (GROUP A STREP)
Erysipelas: streptococcus pyogenes
32

Acute glomerulonephritis
33
Impetigo/Erysipelas
Transmission:
Diagnosis:
Treatment:
Transmission: person-to-person or formite (object)
Diagnosis: presence of yellow vesicles (impetigo)
Treatment: antibiotics
34
Necrotizing fasciitis is usually caused by...
Streptococcus pyogenes
35
Necrotizing fasciitis
Transmission:
Diagnosis:
Treatment:
Transmission: person-to-person, breaks in skin
Diagnosis: difficult early on because generic
Treatment: IV antibiotics, surgical debridement (clean up dead tissue)
36
Acne stages...
1. Normal skin; oily sebum is produced & discharged through pore
2. Whitehead; inflammed skin causes bacteria and sebum accumulation
3. Blackhead; dead and dying bacteria block pore
4. Pustule formation: severe inflammation of hair follicle
37

43
Gas gangrene
Symptoms:
Vegetative cells:
Mortality rate:
Treatment:
Symptoms: necrosis (dead tissue; connective and muscle) and black gas bubble
