Answer

Bronchiectasis may be the sequela of a variety of necrotizing infections that are either inadequately treated or not treated at all. Primary infection (ie, in the absence of intrinsic defects or noninfectious extrinsic insults) was a particularly common cause of bronchiectasis in developed countries prior to the widespread use of antibiotics [14] and it remains important in developing countries, where antibiotics are used inconsistently. [15, 16]
