Acute pyelonephritis due to bacteria has identical morphology regardless of which bacteria is causal. Suppurative Inflammation. Acute, subacute and chronic inflammation •Acute inflammation −lasts from several days up to several months −in the focus of inflammation - neutrophils, intravascular platelet activation −Exudative inflammation and rarely observed productive (viruses) •Subacute inflammation −lasts from several weeks up to several months −in the focus of inflammation - neutrophils, lymphocytes .

Morphology The prime feature of chronic inflammation is the prominent presence of macrophage and lymphocytes, including \ B-cells , Plasma Cells , and T-cells , at the site of injury. Sequence of Events 1. Cellular swelling (synonyms: hydropic change, vacuolar degeneration, cellular edema) is an acute reversible change resulting as a response to nonlethal injuries. Six morphologic patterns of inflammation are described: 1) segregated glandular inflammation, 2) periglandular inflammation, 3) diffuse stromal inflammation, 4) isolated stromal lymphoid nodules, 5) acute necrotizing inflammation and 6) focal granulomatous inflammation.

John Hunter (1728-1793, London surgeon and anatomist) was the first to realize that acute inflammation was a response to injury that was generally beneficial to the host: "But if inflammation develops, regardless of the cause, still it is an effort whose purpose is to restore the parts to their natural functions." Bronchopneumonia affects one or more lobes . painful nodules in legs. 2. lead to: Transudation of watery, low protein fluid into body cavities.

Acute inflammation is rapid in onset (typically minutes) and is of short duration, lasting for hours or a few days; its main characteristics are the exudation of fluid and plasma proteins (edema) and the emigration of leukocytes, predominantly neutrophils (also called polymorphonuclear leukocytes). It is easy to be observed in parenchymal Bronchopneumonia (Lobular pneumonia) is an acute exudative suppurative inflammation of the lungs characterized by foci of consolidation surrounded by normal parenchyma.
