Is Stenotrophomonas maltophilia gram-negative?
Is Stenotrophomonas maltophilia gram-negative?
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.
What kills Stenotrophomonas maltophilia?
The treatment of choice for Stenotrophomonas maltophilia is trimethoprim-sulfamethoxazole (SXT). Fluoroquinolones (FQs) have in vitro activity against S.
Is it serious to have Stenotrophomonas maltophilia in your system?
Stenotrophomonas maltophilia is a globally emerging pathogen that causes serious infectious complications in immunocompromised patients in particular. It also exhibits a wide range of drug resistance mechanisms and this complicates the management of infections caused by this GNB.
What infections does Stenotrophomonas maltophilia cause?
The most commonly encountered infectious complications related to S. maltophilia are pneumonia, bacteremia, and CVC-related infections. S. maltophilia may coexist with other infections caused by bacterial, viral, fungal, and protozoal agents (5, 6).
Is Stenotrophomonas maltophilia the same as Pseudomonas?
Stenotrophomonas maltophilia is an opportunistic pathogen that was transferred from the genus Pseudomonas via the Xanthomonas group to the newly defined genus Stenotrophomonas.
What is maltophilia infection?
Background. Stenotrophomonas maltophilia previously known as (Xanthomonas) maltophilia is an aerobic gram-negative bacillus that is found in various aquatic environments. Although an uncommon pathogen in humans, S maltophilia infection in humans, especially nosocomial, has been increasingly recognized.
How do you get rid of Stenotrophomonas?
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.
Where do you get 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.
Is Stenotrophomonas 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.
Where is Maltophilia found?
Stenotrophomonas maltophilia (SMA) is a non-fermenting gram-negative bacillus found in plants and soil and on the surface of human skin. It is present in hospital environments and is detected in the respiratory and intestinal tracts.
