The study of disease

Steps to prove a pathogen causes a disease

Categorizing diseases based on spread (communicable/noncommunicable) and ease of spread (contagious)

Types of bacteria, fungi and other microbes living on the human skin's surface

Diseases caused by microbes impacting the skin (bacteria, viruses, fungi or insects)

Skin conditions caused by bacteria

Skin conditions caused by viruses

Skin conditions caused by fungi

Small, fluid-filled lesions on the skin.

Larger fluid-filled lesions on the skin, greater than 1 cm in diameter.

Flat, reddened lesions on the skin, without elevation.

Raised lesions on the skin, solid and firm.

Raised lesions on the skin filled with pus.

A skin rash arising from a systemic disease.

A common bacterium found on the skin of most people, usually harmless, but can cause infections in vulnerable individuals.

A bacterium commonly found in the nasal passage, which can cause various skin infections and even sepsis.

A bacterial skin infection caused by Streptococcus pyogenes, characterized by crusting sores that spread easily through autoinoculation.

A severe form of impetigo caused by Staphylococcus aureus, resulting in blistering and peeling of the skin, resembling a severe sunburn.

A potentially life-threatening condition caused by toxins released from Staphylococcus aureus, leading to fever, vomiting, shock, and organ failure.

A type of bacteria responsible for various infections, including strep throat, cellulitis, and impetigo. The most common member is Streptococcus pyogenes.

Virulence factors produced by Streptococcus pyogenes that allow the bacteria to stick to surfaces and evade the immune system.

A skin infection caused by Streptococcus pyogenes affecting the superficial layers of the skin, characterized by redness, swelling, and pain.

A deeper skin infection caused by bacteria entering through a break in the skin, leading to inflammation and swelling.

A rare but serious flesh-eating disease caused by bacteria, often Streptococcus pyogenes, that destroys the tissue under the skin.

A gram-negative, aerobic rod bacterium that produces toxins and can form biofilms. Often opportunistic in burn patients and resistant to many antibiotics.

A skin infection caused by Pseudomonas aeruginosa, often acquired in swimming pools. Characterized by a self-limiting rash that usually resolves on its own.

An infection of the outer ear canal often caused by Pseudomonas aeruginosa. Commonly acquired in swimming pools.

A gram-positive bacteria that causes Buruli ulcer, a deep and damaging skin infection. It produces a toxin called mycolactone and is often transmitted via skin breaks or insect bites.

A chronic skin infection caused by Mycobacterium ulcerans, characterized by deep, destructive ulcers that may require amputation.

An anaerobic bacterium that causes inflammatory acne. It thrives on sebum and fatty acids, leading to inflammation in the hair follicles.

A type of acne characterized by inflamed lesions caused by Propionibacterium acnes. Often treated with antibiotics and benzoyl peroxide.
