• 
  This gross photograph of lung demonstrates microabscesses due to septic embolization. Note the small 2 to 3-mm lesions scattered throughout this lung tissue (arrows).
• 
  This is a gross photograph of myocardium with multiple embolic lesions scattered throughout the left and right ventricles.
• 
  This low-power photomicrograph shows a section of lung on the left and myocardium on the right. Both pieces of tissue have multiple embolic lesions seen as blue staining areas with massive infiltration of inflammatory cells (arrows).
• 
  This is a higher-power photomicrograph of the focal lesions in the lung produced by the septic emboli. Note these are clearly demarcated from the relatively normal surrounding lung tissue.
• 
  This is a higher-power photomicrograph of one of these septic abscesses illustrating the colonies of bacteria within necrotic cellular debris (arrows). This is typical of an abscess.
• 
  This is a low-power photomicrograph of myocardium with septic abscesses (arrows).
• 
  This is a higher-power photomicrograph of the abscess within the myocardium illustrating colonies of bacteria as the dark blue-staining material (arrow).
• 
  This is a high-powered photomicrograph of a myocardial abscess stained with a special tissue Gram stain (Brown & Brenn) to illustrate the colonies of bacteria in this myocardial tissue (arrows).

Sepsis is the presence and persistence of pathogenic microorganisms and their toxins in the blood.

Plural of embolus. An embolus is something that blocks the blood flow in a blood vessel. It may be a gas bubble, a blood clot, a fat globule, a mass of bacteria, or other foreign body. It usually forms somewhere else and travels through the circulatory system until it gets stuck.

An abscess is a collection of pus (white blood cells) within a cavity formed by disintegrated tissue.
