<P> `` Atypical pneumonia '' is atypical in that it is caused by atypical organisms ( other than Streptococcus pneumoniae , Haemophilus influenzae , and Moraxella catarrhalis ) . These atypical organisms include special bacteria , viruses , fungi , and protozoa . In addition , this form of pneumonia is atypical in presentation with only moderate amounts of sputum , no consolidation , only small increases in white cell counts , and no alveolar exudate . At the time that atypical pneumonia was first described , organisms like Mycoplasma , Chlamydophila , and Legionella were not yet recognized as bacteria and instead considered viruses . Hence `` atypical pneumonia '' was also called `` non-bacterial '' . In literature the term atypical pneumonia ( contrasted with bacterial pneumonia ) is still in use , though incorrect . Meanwhile , many such organisms are identified as bacteria , albeit unusual types ( Mycoplasma is a type of bacteria without a cell wall and Chlamydias are intracellular parasites ) . As the conditions caused by these agents have different courses and respond to different treatments , the identification of the specific causative pathogen is important . </P>
