Purulent inflammation: Inflammation resulting in large amount of pus, which consists of neutrophils, dead cells, and fluid. Infection by pyogenic bacteria such as staphylococci is characteristic of this kind of inflammation. Large, localised collections of pus enclosed by surrounding tissues are called abscesses.
Hemorrhaging: This type of drainage contains frank blood from a leaking blood vessel. This will require emergency treatment to control the bleed. This type of drainage is abnormal. Purulent drainage: This type of drainage is malodorous and can be yellow, gray, or greenish in color. This is an indication of an infection.
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 ...
More recently, several North American hospitals have opted for less-invasive loop drainage over standard drainage and wound packing. In one study of 143 pediatric outcomes, a failure rate of 1.4% was reported in the loop group versus 10.5% in the packing group (P<.030), [32] while a separate study reported a 5.5% failure rate among the loop ...
Microscopically, the cystic space contains necrotic cell debris and macrophages filled with phagocytosed material. The cyst wall is formed by proliferating capillaries, inflammatory cells, and gliosis (proliferating glial cells) in the case of brain and proliferating fibroblasts in the case of abscess cavities. Brain cells have a large amount ...
Gas gangrene; Other names: Myonecrosis, [clarification needed] clostridial myonecrosis Photograph before right leg amputation (hemipelvectomy) of a patient with gas gangrene.The right thigh is edematous (swollen) and discoloured with necrotic bullae (large blisters).
The anginosus group streptococci are members of the viridans streptococci group. [1] They have been implicated as etiologic agents in a variety of serious purulent infections, but because of their heterogeneous characteristics, these organisms may be unrecognized or misidentified by clinical laboratorians.

Purulent sputum [5] contains pus, composed of white blood cells, cellular debris, dead tissue, serous fluid, and viscous liquid . Purulent sputum is typically yellow or green. It is seen in cases of pneumonia, bronchiectasis, lung abscess, or an advanced stage of bronchitis. [6]
