What is Sphingobacterium multivorum?
Sphingobacterium multivorum is a Gram-negative, nonfermentative bacillus that rarely causes disease in humans. In the medical literature, only a few cases of infections caused by this organism have been reported. Almost all the reported cases of this infection were associated with conditions that decrease immunity.
What is Sphingobacterium Spiritivorum?
Sphingobacterium spiritivorum is a glucose non-fermenting Gram-negative rod, formerly classified as one of the Flavobacterium species. It is characterized by a large number of cellular membrane sphingophospholipids. Sphingobacterium species are ubiquitous and isolated from natural environments, such as soil and water.
What is unique about the Sphingobacterium SPP?
Sphingobacterium species are intrinsically resistant to many commonly employed antibiotics and can grow in some antiseptics and disinfectants. S. multivorum can produce an extended-spectrum β-lactamase and a metallo-β-lactamase conferring resistance to third-generation cephalosporins and carbapenems, respectively.
Where is Sphingobacterium found?
These microorganisms are ubiquitous in nature but are rarely involved in human infections. Sphingobacterium can be found in soil, on plants, in foodstuffs and in water sources [3].

What does Stenotrophomonas maltophilia do?
Conclusion. 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 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.
What is the cause of Stenotrophomonas?
Stenotrophomonas maltophilia (S. maltophilia) infections are caused by the S. maltophilia bacteria . These bacteria live in wet environments.
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.
Why is Stenotrophomonas resistant to antibiotics?
Introduction: Stenotrophomonas maltophilia is a prototype of bacteria intrinsically resistant to antibiotics. The reduced susceptibility of this microorganism to antimicrobials mainly relies on the presence in its chromosome of genes encoding efflux pumps and antibiotic inactivating enzymes.
Where are stenotrophomonas from?
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.
Is Sphingobacterium multivorum a dangerous microorganism?
Original article Sphingobacterium multivorum: case report and literature review. S. multivorum, a Gram-negative bacillus, is ubiquitous in nature and is rarely involved in human infections. However, it is intrinsically resistant to many commonly administered antibiotics and can be a life-threatening microorganism.
What is Sphingobacterium multivorum bacteraemia septic shock?
We describe the case of a 67-year-old African American woman with multiple medical problems who presented with septic shock resulting from Sphingobacterium multivorum bacteraemia. S. multivorum, a Gram-negative bacillus, is ubiquitous in nature and is rarely involved in human infections.
How many species of Sphingobacterium are there?
The genus Sphingobacterium consists of six species: S. spiritovorum, S. multivorum, S. mizutaii, S. antarcticum, S. faecium and S. thalpophilum. The species S. multivorum and S. spiritovorum have been associated with bacteremia, peritonitis, and chronic respiratory infection in patients with severe underlying conditions [ 9 – 13 ].
Is Sphingobacterium Gram positive or negative?
Bacteria that belong to the genus Sphingobacterium are Gram-negative, non-fermentative microorganisms that are positive for catalase and oxidase tests. They are ubiquitous in nature, but are rarely involved in human infections.
