Examples of Fibrinous Inflammation and Seqeulae Acute diffuse fibrinopurulent peritonitis in a dog. Acute locally-extensive fibrinous pleuritis in a goat. Pleural fibrous adhesions resulting from repaired fibrinous pleuritis in a pig. One refers to inflammatory exudate, the other the product of a repair process. Exudate is dominated by collections of neutrophils.
Exudate varies from yellow white to gray white and watery to viscous in consistency.
Pus is a term used to describe an accumulation of purulent exudate. Suppuration refers to the process of accumulation of purulent or suppurative exudate. An abscess is a circumscribed collection of pus. Accumulation of large numbers of neutrophils in tissues is associated with neutrophil necrosis and neutrophil-induced tissue damage. Occurs commonly in hypersensitivity diseases and in metazoon parasite infestations.
