What is the cause of Stenotrophomonas maltophilia?
Sources of Stenotrophomonas maltophilia infections have included sink drains, hand-washing soap, contaminated disinfectants, nebulizers, and even hospital suction tubing. Additionally, showerheads and faucets tend to be a favorite hiding spot for the bug.
Where is Stenotrophomonas maltophilia found?
S. maltophilia is an environmental bacterium found in aqueous habitats, including plant rhizospheres, animals, foods, and water sources. Infections of S. maltophilia can occur in a range of organs and tissues; the organism is commonly found in respiratory tract infections.
What type of infection is Stenotrophomonas?
Stenotrophomonas (Xanthomonas) maltophilia is a multidrug-resistant gram-negative bacillus that is an opportunistic pathogen [1-4], particularly among hospitalized patients. S. maltophilia infections have been associated with high morbidity and mortality in severely immunocompromised and debilitated individuals.
Is there a cure for Stenotrophomonas maltophilia?
The treatment of choice for Stenotrophomonas maltophilia is trimethoprim-sulfamethoxazole (SXT). Fluoroquinolones (FQs) have in vitro activity against S. maltophilia; however, there is limited published information on their effectiveness.
Can Stenotrophomonas be cured?
1. Trimethoprim-Sulfamethoxazole (TMP-SMX) The mainstay of treatment for Stenotrophomonas infections is trimethoprim-sulfamethoxazole (TMP-SMX) and it remains the current drug of choice.
Is Stenotrophomonas maltophilia fatal?
Purpose: Stenotrophomonas maltophilia has low pathogenicity potential, but if it causes bacteremia it can be fatal, because it has shown high resistance to many antibiotics and can be difficult to treat. Patient death from S. maltophilia bacteremia has increased since 2014 in our hospital.
How serious is Stenotrophomonas?
How long do you treat Stenotrophomonas?
The typical duration of antimicrobial courses for Stenotrophomonas maltophilia pneumonia is usually 7 days, which can be extended to 10 to 14 days in immunosuppressed patients. Bacteremia cases, on the other hand, are generally treated for 14 days total.
What antibiotics treat Stenotrophomonas?
How can Stenotrophomonas maltophilia be prevented?
Effective infection control measures can minimize or limit the spread of this and other organisms in the ICU. Appropriate isolation procedures, rather than antimicrobial therapy, should be used to control the spread of S maltophilia.
