What shape is Stenotrophomonas?
Curved, straight or bean-shaped: bacilli come in many variants and are widely spread. Stenotrophomonas maltophilia is an aerobic, Gram-negative, rod-shaped bacterium of the Xanthomonadaceae family. It may trigger urinary tract infection, respiratory tract infection or bloodstream infection.
How do you identify Stenotrophomonas maltophilia?
To overcome the problems associated with definitive identification, we developed species-specific PCR (SS-PCR) primers, designated SM1 and SM4, directed to the 23S rRNA gene, and tested their utility to accurately identify S. maltophilia directly from sputum.
How do you identify Stenotrophomonas?
Stenotrophomonas maltophilia is a straight, Gram-negative rod. These bacteria are motile due to the presence of 4 polar flagella. They are catalase positive, and most are either negative or weakly oxidase positive.
Is Stenotrophomonas maltophilia motile?
maltophilia is slightly smaller (0.7–1.8 × 0.4–0.7 μm) than other members of the genus. They are motile due to polar flagella, and grow well on MacConkey agar producing pigmented colonies….

What does Stenotrophomonas maltophilia do?
maltophilia experience infections of the heart (endocarditis), the bone behind the ear (mastoiditis), lining of the abdomen and internal organs (peritonitis), cerebral spinal fluid ( meningitis ), soft tissue , wounds, urinary tract, and/or eye. The symptoms are similar to other bacterial infections of the same sites.
What causes Stenotrophomonas maltophilia?
Frequently found in more wet environments, but also animals, food, and water sources, such infections can impact organs and tissue alike. Sources of Stenotrophomonas maltophilia infections have included sink drains, hand-washing soap, contaminated disinfectants, nebulizers, and even hospital suction tubing.
How is Stenotrophomonas maltophilia treated?
The treatment of choice for Stenotrophomonas maltophilia is trimethoprim-sulfamethoxazole (SXT). Fluoroquinolones (FQs) have in vitro activity against S.
What is the cause of Stenotrophomonas maltophilia?
Is Stenotrophomonas a contaminant?
Stenotrophomonas maltophilia (SMA) is present in hospital environments and has been one of the pathogens that cause nosocomial contamination and infections.
Is Stenotrophomonas maltophilia serious?
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.
Can Stenotrophomonas be cured?
Is Stenotrophomonas maltophilia an emerging nosocomial pathogen?
Stenotrophomonas maltophiliais a ubiquitous soil bacterium that is increasingly recognized as an emerging nosocomial pathogen. This unit includes protocols for the in vitrogrowth and maintenance of S. maltophilia. Keywords: Stenotrophomonas maltophilia, laboratory growth, nosocomial, hospital acquired infection INTRODUCTION
How is Stenotrophomonas maltophilia diagnosed?
Diagnosis Diagnosis. Stenotrophomonas maltophilia (S. maltophilia) infection is usually suspected by symptoms of a bacterial infection and risk factors. A small sample of body fluid such as blood, mucus, urine, or abdominal fluid will be cultured to confirm which bacteria is causing the infection.
What is the pathophysiology of S maltophilia?
S. maltophilia may involve any organ. Lungs are frequent sites of infection. Pulmonary infection is often preceded by respiratory tract colonization. Lobular or lobar consolidation is common, whereas pleural effusions are seldom noted.
What is another name for Pseudomonas maltophilia?
Other Names (8): Pseudomonas maltophilia; Xanthomonas maltophilia; Stenotrophomonas africana Stenotrophomonas maltophilia is an aerobic, non-fermentative, gram-negative bacillus possessing flagella in a multitrichous formation, and that naturally lives in the rhizosphere (1).
