[The etiology of acute pneumonia]. 1990

L A Vishniakova, and N V Putov

Based on the results of the authors' own investigations and the reported data it is shown that primary (extrahospital) acute pneumonia (AP) is of pneumococcal etiology in the overwhelming majority of patients. At the same time in 2/3 of cases, AP is associated with influenza and other acute respiratory virus infections. If primary AP runs an unfavourable course, a secondary infectious inflammatory process induced by different opportunistic bacteria may occur. The secondary (intrahospital) APs developing in the presence of marked disorders of the total and local defence are polyetiologic in nature. This is often caused by the association of a number of causative agents belonging to the families of different aerobic and anaerobic bacteria and by a change of etiological factors in the course of the disease. Gram-negative enterobacteria, Pseudomonas and nonsporulating obligate anaerobes are the main causative agents of secondary pneumonias as well as of infectious processes that complicate primary APs.

D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
