Interesting comment for Francophobes at a blog I found:
Well, he hasn't even got the name right, or about anything else for that matter.
Stenotrophomonas (Pseudomonas) maltophilia is ubiquitous, and hardly the cause of the described condition.
Background: Stenotrophomonas (Pseudomonas) maltophilia is an aerobic gram-negative bacillus that is an infrequent pathogen in humans and is found in a variety of aquatic environments. S maltophilia is an organism of low virulence and is a frequent colonizer of fluids used in the hospital setting, ie, irrigation solutions and intravenous (IV) fluids, and of patient secretions, ie, respiratory secretions, urine, or wound exudates. S maltophilia usually must bypass normal host defenses to cause human infection. For example, if fluid in an irrigation solution becomes colonized with this organism, irrigating an open wound can cause colonization or infection of the wound. S maltophilia usually is not capable of causing disease in healthy hosts without the assistance of invasive medical devices that bypass normal host defenses.
Pathophysiology: S maltophilia has few pathogenic mechanisms and, for this reason, predominantly results in colonization rather than infection. If infection does occur, invasive medical devices usually are the vehicles by which the organism bypasses normal host defenses. Otherwise, the pathophysiology of this nonfermentative aerobic gram-negative bacillus is not different from other nonfermentative aerobic organisms.
