Ringworm/TInea (fungal infection).
What are some deeper infections which are typically more serious?

What is impetigo?
What are some common causative organisms of impetigo?
What are abscesses?
A localised collection of pus
What is a furuncle?
What is a carbuncle?

What is cellulitis?
What complications can arise from cellulitis?

What treatment can be used for various severities of cellulitis? (3 Points)
Antistaphylococcal drugs can be used: Flucloxacillin
Antistreptococcal drugs can also be used: Penicillin/erythromycin.
For serious infection, since disease effects are being caused by toxins, protein production inhibiting drugs such as clindamycin can be used in conjunction with another antibiotic.
What is necrotising fasciitis?
What causative organisms are typically responsible for necrotising fasciitis?
How can necrotising fasciitis be diagnosed?
Microscopy of tissue and fluid samples.
