S. maltophilia fulfils important ecosystem functions in the sulfur and nitrogen cycles, in degradation of complex compounds and pollutants, and in promoti on of plant growth and health. Stenotrophomonas can also colonize extreme man-made niches in hospitals, space shuttles, and clean rooms.

If a patient’s wound is irrigated with colonized solution, this allows the bacteria to bypass the body’s natural defenses and cause infection. S maltophilia is intrinsically resistant to multiple antibiotics due to β-lactamase production and expression of multidrug-resistance efflux pumps. 1 As a result, S maltophilia infections are challenging to treat. Here, we aim to provide a brief review of current and potential treatment options for S maltophilia infections. 2020-05-14 · S. maltophilia strains occur in several natural and human associated ecosystems.The bacterium was long regarded as relatively unproblematic but is now considered to be one of the most feared hospital pathogens, as it frequently causes infections and is resistant to a number of antibiotics.

The objectives of this study were to evaluate and compare the in vitro activities and to understand the mechanisms of resistance to aztreonam in combination with avibactam, clavulanate, relebactam, and vaborbactam against S. maltophilia A panel of 47 clinical S. maltophilia strains nonsusceptible to levofloxacin and/or trimethoprim-sulfamethoxazole were tested against each aztreonam-BLI Finally, the in vitro activities of recently approved tetracycline derivatives, eravacycline and omadacycline, have been reported for S. maltophilia (24 – 29), but no studies to date have simultaneously assessed the activity of both agents or either agent specifically against S. maltophilia isolates resistant to levofloxacin and/or TMP-SMZ, and no clinical data exist to support their use. Stenotrophomonas maltophiliaは，1943年にBacterium bookeriと命名された好気性のブドウ糖発酵グラム陰性桿菌である．その後，Pseudomonas属あるいはXanthomonas属に分類されていたが，1993年にStenotrophomonas属に分類された．Stenotrophomonas属菌は植物病原体として知られ，土壌，水，動物，植物などから分離される．S 2020-04-27 · S. maltophilia complex comprises 23 monophyletic lineages. To investigate the global diversity of the S. maltophilia complex, a maximum likelihood phylogeny was inferred from a concatenated S. maltophilia was first identified in 1943 in the United Kingdom and was named Bacterium bookeri.It was previously considered a pseudomonad and was grouped under the genus Xanthomonas in 1983, but a decade later it was reclassified as the single species of the new genus Stenotrophomonas. 2006-09-18 · S. maltophilia is becoming increasingly recognised as an important nosocomial pathogen [1, 2].The increase is most likely due to an increase in the patient population at risk because of the advances in medical therapeutics that include: the aggressive treatment of malignancy, the increase in invasive therapeutic devices and the increased utilization of broad – spectrum antimicrobials []. s/tの耐性率は世界的には上記のように5％程度．これは現在上昇傾向にあり，25％をこえる地域もある．(日本は多分含まれていない)[2] 血流感染においては複数菌を伴って検出されることも20～40％と多めであり，本症例でもAcinetobacter baumaniiを伴った形で菌血症が発症している．[2] Stenotrophomonas maltophilia（以下S. maltophilia と略）による肺感染症は1979年Sarkarら1）により最初に報告され，本邦においては1994年Irifuneら3）により初めて報告された．その後本菌は時代の推移と共に，カルバペネムをはじめとする多剤に耐性の菌であるところ Stenotrophomonas maltophilia: Experiment type: Expression profiling by high throughput sequencing: Summary: We characterized the transcriptional responses of three S. maltophilia strains during exposure to synthetic CF sputum media (SCFM2) to gain insight into how this organism interacts with the host in the CF lung. S. maltophilia fulfils important ecosystem functions in the sulfur and nitrogen cycles, in degradation of complex compounds and pollutants, and in promoti on of plant growth and health.

It also occurs Among the causative pathogens, Stenotrophomonas Maltophilia is a rare pathogen, but affects usually patients with chronic pulmonary co-morbidities, or with May 18, 2020 The antibiotic-resistant bacterium S. maltophilia, a threat to those with lung diseases such as CF, is widely spread around the world, a study Aug 15, 2019 Introduction. Stenotrophomonas maltophilia is a nonfermenting Gram-negative rod that is ubiquitous in nature (predominantly occurring in aquatic Sep 18, 2018 Antibiogram - Stenotrophomonas maltophilia. Number of Isolates Identified - 36.

S. maltophilia is a type of bacteria that can cause a hospital-acquired infection. Depending on where the infection happens, it can be life-threatening or merely debilitating. S. maltophilia bacteria are resistant to many kinds of antibiotics, so treating an infection can be difficult.

We considered that CZA was more effective in vitro than TZ alone if CZA led to a category change (from “Resistant” with TZ to “Susceptible” or “Intermediate” with CZA), or if the MIC of CZA was at least 4-fold lower than the MIC of TZ for isolates susceptible to TZ. In a single centre study, S. maltophilia was associated with an acceleration in lung function decline and an increase in hospitalization rate. 5 In another study, it has been shown that subjects with CF bronchiectasis and S. maltophilia isolation have more frequent pulmonary exacerbations, hospitalizations and intravenous (IV) antibiotic courses as compared to controls, 6 suggesting that S S. maltophilia strains have an extraordinarily high hydrolytic potential; they produce diverse proteases, chitinases, glucanases, DNases, RNases, lipases and laccases.

ABSTRACT. Despite its limited pathogenicity, Stenotrophomonas maltophilia is an emerging nosocomial pathogen. This study investigated the isolation frequency,

The name signifies "a unit feeding on few substrates," based on the Greek roots stenos (narrow), trophos (one who feeds), and monas (a unit). S. maltophilia are catalase-positive, oxidase-negative (which distinguishes them from most other members of the genus) and have a positive reaction for extracellular DNase.

Stenotrophomonas maltophilia is an emerging multidrug-resistant global opportunistic pathogen. The increasing incidence of nosocomial and community-acquired S. maltophilia infections is of particular concern for immunocompromised individuals, as this bacterial pathogen is associated with a significant fatality/case ratio. S. maltophilia is an environmental bacterium found in aqueous habitats

S. maltophilia se posiciona hoy en día como un patógeno nosocomial de ámbito general, añadiéndose a otros multirresistentes como Staphylococcus aureus, Acinetobacter spp. y Pseudomonas aeruginosa, falta por delimitar su trascendencia real como patógeno relacionado con la atención sanitaria extrahospitalaria.
