Bacterial and fungal species isolated from 2020 CVCs in different years. CVC, central venous catheter; CoNS, coagulase-negative staphylococci (a) The total composition of isolated organisms on 2020 CVCs surfaces; (b) the composition of isolated organisms on CVC surface in different years. The changes of proportion of color block in (b) indicate the proportion of Gram-negative bacteria decreased gradually from 2013 to 2017 and fungus with diversified internal composition was presented accompanied by the proportion of non-Candida albicans increasing in 2017.
