Histopathological changes of brain showed severe gliosis, dark neurons, and vacuolization in fish exposed to tramadol compared to control fish. Gills tissue showed erosion, epithelial lifting, and secondary lamellae shrinking in fish exposed to tramadol compared to control fish. In conclusion, tramadol induced histopathological changes in liver, brain, and gills of Oreochromis niloticus as well as poikilocytosis were indicated clearly. Therefore, tramadol leakage to waters should be avoided to preserve aquatic creatures. OBJECTIVES Ventilator-associated pneumonia (VAP) is a significant cause of prolonged hospital stay and increased mortality in mechanically ventilated children. Studies of relationship between bacterial colonization of ventilator circuit (VC) and VAP are lacking. This study aimed to investigate the role of bacterial colonization of VC in development of VAP, and to provide evidence for preventing VAP. METHODS Mechanically ventilated patients admitted to PICU of a teaching hospital in China from October 2018 to November 2019 were enrolled. Specimens were collected from VC and patient's lower respiratory tract (LRT) for bacterial culture. Paired bacteria isolated from VC and patient's LRT, where colonization of VC preceded that of LRT, were evaluated for relatedness using pulsed field gel electrophoresis (PFGE). RESULTS A total of 114 patients were included, incidence rate of VAP was 28.1% (32/114). 1368 samples were collected from VCs, with 16% of positive bacterial culture. There was no significant difference in bacterial colonization of VC between VAP and non-VAP. Of 13 patients, LRT and VC were concurrently colonized with the same bacteria, where colonization of VC occurred before patient's LRT. PFGE results demonstrated high co
