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]

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.
The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches , staples or sutures .
