Bronchopneumonia or bronchial pneumonia or Bronchogenic pneumonia (not to be confused with lobar pneumonia) is the acute inflammation of the walls of the bronchioles. It is a type of pneumonia characterized by multiple foci of isolated, acute consolidation, affecting one or more pulmonary lobules. It is one of two types of bacterial pneumonia as classified by gross anatomic distribution of consolidation (solidification), the other being ''lobar pneumonia''. ==Associated conditions== Bronchopneumonia is less likely than lobar pneumonia to be associated with Streptococcus.〔(【引用サイトリンク】title=Lobar Pneumonia )〕 The bronchopneumonia pattern has been associated with hospital-acquired pneumonia, and with specific organisms such as Staphylococcus aureus, Klebsiella, E. coli, and Pseudomonas.〔(【引用サイトリンク】title=Pulmonary Pathology )〕 In bacterial pneumonia, invasion of the lung parenchyma by bacteria produces an inflammatory immune response. This response leads to a filling of the alveolar sacs with exudate. The loss of air space and its replacement with fluid is called consolidation. In bronchopneumonia, or lobular pneumonia, there are multiple foci of isolated, acute consolidation, affecting one or more pulmonary lobes. Although these two patterns of pneumonia, lobar and lobular, are the classic anatomic categories of bacterial pneumonia, in clinical practice the types are difficult to apply, as the patterns usually overlap. Bronchopneumonia (lobular) often leads to lobar pneumonia as the infection progresses. The same organism may cause one type of pneumonia in one patient, and another in a different patient. From the clinical standpoint, far more important than distinguishing the anatomical subtype of pneumonia, is identifying its causative agent and accurately assessing the extent of the disease. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bronchopneumonia」の詳細全文を読む スポンサード リンク
