Stenotrophomonas maltophilia is an aerobic, nonfermentative, Gram-negative bacterium.It is an uncommon bacterium and human infection is difficult to treat. [1] Initially classified as Bacterium bookeri, [2] then renamed Pseudomonas maltophilia, S. maltophilia was also grouped in the genus Xanthomonas before eventually becoming the type species of the genus Stenotrophomonas in 1993.
Person-to-person spread has been documented; as a result, many hospitals, clinics, and camps have enacted strict isolation precautions for those infected with BCC. Infected individuals are often treated in a separate area from uninfected patients to limit spread, since BCC infection can lead to a rapid decline in lung function and result in death.
The lack of newly emerging antimicobrial drugs have resulted in the revisit of old antibiotic drugs such as colistin (Polymyxins) and fosfomycin, which are traditionally considered to be toxic but have gained a principal role in the treatment of the most problematic MDR Gram-negative pathogens including Pseudomonas aeruginosa, Acinetobacter ...
The aspergillosis cases were detected at University Crosshouse Hospital in Kilmarnock earlier this year.
Members of the genus Stenotrophomonas have an important ecological role in the nitrogen and sulphur cycles. Stenotrophomonas species, especially S. maltophilia and S. rhizophila, are often found in association with plants, such as cucumber, oilseed rape, potato, strawberry, alfalfa, sunflower, maize, rice, wheat, various weeds, willow and poplar.
Washing hands as promptly and thoroughly as possible between patient contacts and after contact with blood, body fluids, secretions, excretions, and equipment or articles contaminated by them is an important component of infection control and isolation precautions. The spread of nosocomial infections, among immunocompromised patients is ...
Ashdown's medium (or Burkholderia cepacia medium) may be used for selective isolation. [12] Cultures typically become positive in 24 to 48 hours (this rapid growth rate differentiates the organism from B. mallei, which typically takes a minimum of 72 hours to grow). Colonies are wrinkled, have a metallic appearance, and possess an earthy odor.
Stenotrophomonas is the only genus capable of nitrate reduction within the Xanthomonadales. Taxonomy. The Xanthomonadales consist of 28 validly named genera among ...
