The genus Stenotrophomonas belongs to the so-called gram-negative non-fermenting bacteria , this group includes genera showing similar characteristics as this genus, they are the genus Pseudomonas and the genus Burkholderia . Due to their common characteristics and traits, these genera can be put into context, in the medical sense, these genera are important mainly in terms of nosocomial diseases .
Taxonomy
The taxonomy of the genus Stenotrophomonas is constantly renewed, the current classification is as follows:
- class Gammaproteobacteria
- order Xanthomonadales
- family Xanthomonadaceae
- genus Stenotrophomonas
- species - there are several species, the most risky representative is considered a bacterium - Stenotrophomonas maltophilia
Characteristics
This genus is characterized by delayed biochemical activity. Furthermore, they do not stain in the oxidase test , so they are oxidase negative. Like the previous genus Pseudomonas , the genus Stenotrophomonas is the cause of nosocomial infections .
Important representatives
Stenotrophomonas maltophilia is considered to be the most risky representative of the genus Stenotrophomonas . It is highly resistant to most anti-pseudomonad drugs, such as aminoglycosides , ceftazidime or piperacillin . In contrast, fluoroquinolones and cotrimoxazole are effective against it .
