  7. 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. They grow on MacConkey agar and appear to be nonfermenters.

Stenotrophomonas maltophilia is rather unique in the way that it has both an intrinsic set of multi-drug resistances, as well as a variety of intrinsic methods for handing the influx of metal ions. However, as previously stated, Stenotrophomonas maltophilia also grants certain plant species protection against various plant pathogens, and thus is also being studied for the use of bio-pesticides. Stenotrophomonas maltophilia colonization/infection in patients with cancer has significantly increased over the past 2 decades. Patients with prolonged neutropenia, exposure to broad-spectrum antibiotics, and those requiring mechanical ventilation have higher risk of infection Stenotrophomonas maltophilia (S. maltophilia) infection is a type of bacterial infection.S. maltophilia is found mostly in wet environments. In the hospital setting, S. maltophilia can be found in fluids, such as irrigation solutions (fluids used to clean a wound or wash out a body cavity like the ear canal or bladder) and intravenous (IV) fluids, as well as patient secretions, such as mucus.

Treatment of S. maltophilia infections is also complicated by the fact that isolates are re Background: Stenotrophomonas (Xanthomonas) maltophilia has emerged as a causative agent of serious nosocomial infections. However, well-documented eases of urinary tract infection with this organism have rarely been reported

Stenotrophomonas maltophilia (S. maltophilia) is a nosocomial pathogen and a rare cause of infective endocarditis (IE). Given the intrinsic resistance to many classes of antibiotics, IE due to S. maltophilia carries significant morbidity and mortality among the cases described. Prompt identification of risk factors, particularly the use of medical devices, is necessary for the timely. Introduction. The now known Stenotrophomonas maltophilia species was originally classified as a member of the genus Pseudomonas in 1961 (Hugh and Ryschenkow 1961) and then Xanthomonas in 1983, finally coming to rest in Stenotrophomonas in 1993. The genus Stenotrophomonas belongs to the γ‐proteobacteria and includes ten species: Sten. maltophilia (Palleroni and Bradbury 1993. Stenotrophomonas maltophilia, formerly known as Xanthomonas maltophilia or Pseudomonas maltophilia, has increasingly become an important nosocomial pathogen.
