Laboratory Studies

Culture of the organism from body fluids and proper identification from the microbiology laboratory confirms the presence of S maltophilia. Usually, the presence of S maltophilia represents colonization. A potential pathogenic role must be evaluated by an infectious disease specialist. The mere recovery of a potential pathogen from any body fluid does not indicate a pathogenic role for the organism.


Histologic Findings

The histology of S maltophilia in the rare situations when it causes infection is indistinguishable from the histology of infections caused by other aerobic gram-negative bacilli.
