Purpose: Despite its low pathogenic characteristics, S.maltophilia is a microorganism that can be colonized in long-term patients in immune and intensive care units, selected from the respiratory and gastrointestinal system, often causing infections such as pneumonia and bacteria. It is known that patients with cystic fibrosis are at risk. The aim of our study is to obtain local epidemiological data by examining S. maltophilia isolat and trimetoprim-sulfometaksazole (TMP-SXT) sensitivity status. Tools and Methods: From 1 January 2018 to 31 May 2019, the 96 S. maltophilia isolate, isolated from the cultural samples of patients who come to the Kahramanmaraş Milk Imam University Medical School Hospital, was retrospective examined. The results: S. A significant proportion of maltophilia (50%) was isolated from respiratory samples, with resistance to TMP-SXT at 1,04% (n=1) found. The result: the fact that Stenotrophomonas maltophilia is resistant to many antibiotics causes difficulties in treatment. TMP-SXT Stenotrophomonas is the most effective antibiotic that can still be used in maltophilia infections. Especially when S. maltophilia is isolated from cultural samples, the factor-colonization distinction should be made and the development of resistance should be prevented by avoiding unnecessary antibiotic use.

Objectives: S.maltophilia despite its low pathogenicity, can cause colonization in immunocompetent and long-term inpatients in the intensive care unit, and can cause pneumonia and bacteremia, often selected from the respiratory and gastrointestinal tract. It is known that especially cystic fibrosis patients are at risk. The aim of this study was to obtain local epidemiological data by examining S. maltophilia isolates and trimetoprim-sulfometaxazole (TMP-SXT) susceptibility. Methods: Ninetysix S. maltophilia isolates, isolated from culture samples sent to Kahramanmaraş Sütçü İmam University Medical Faculty Hospital Microbiology Laboratory between January 1, 2018 and May 31, 2019 were analyzed retrospectively. Results: A significant portion (50%) of S.maltophilia was isolated from respiratory tract samples and resistance to TMP-SXT was found to be 1.04% (n = 1). Conclusion: Stenotrophomonas maltophilia is resistant to many antibiotics, causing treatment difficulties. TMP-SXT is the most effective antibiotic that can still be used in Stenotrophomonas maltophilia infections.Especially when S. maltophilia is isolated from cultural examples, pathogen/ colonization should be differentiated and resistance should be prevented by avoiding unnecessary antibiotic use.
