The final structure of the abscess is an abscess wall, or capsule, that is formed by the adjacent healthy cells in an attempt to keep the pus from infecting neighboring structures. However, such encapsulation tends to prevent immune cells from attacking bacteria in the pus, or from reaching the causative organism or foreign object. [26]

A naked eye exam of the sputum can be done at home by a patient in order to note the various colors (see below). Any hint of yellow or green color suggests an airway infection (but does not indicate the type of organism causing it). Such color hints are best detected when the sputum is viewed on a very white background such as white paper, a ...
Atrophy refers to a loss of skin, and can be epidermal, dermal, or subcutaneous. [30] With epidermal atrophy, the skin appears thin, translucent, and wrinkled. [29] Dermal or subcutaneous atrophy is represented by depression of the skin. [29] Maceration: softening and turning white of the skin due to being consistently wet.
A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle.It is most commonly caused by infection by the bacterium Staphylococcus aureus, resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. [1]
Actinomycosis abscesses grow larger as the disease progresses, often over months. In severe cases, they may penetrate the surrounding bone and muscle to the skin, where they break open and leak large amounts of pus, which often contains characteristic granules filled with progeny bacteria. These granules are often called "sulfur granules" due ...
Microaerophilic bacteria do not grow at all aerobically or grow poorly, but grow better under 10% carbon dioxide or anaerobically. Anaerobic bacteria can be divided into strict anaerobes that can not grow in the presence of more than 0.5% oxygen and moderate anaerobic bacteria that are able of growing between 2 and 8% oxygen.

Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn. [2] In liquefactive necrosis, the affected cell is completely digested by hydrolytic enzymes , resulting in a soft, circumscribed lesion consisting of pus and the fluid remains of necrotic tissue.
