ABSTRACT
Objective:
To study of change of Th17 cell and IL-17 caused by bacteria biofilm after infection.Methods:
To detect biofilm formation ability of bacteria isolated from bronchus alveolus washing-water of patients;to detect expressing ratios of Th17 cells and IL-17 level in peripheral blood of patients and healthy person;to detect expressing ratios of Th17 cells and IL-17 level in bronchus alveolus washing-water of patients;to analyze the above data using SPSS17.0 software.Results:
Expressing ratios of Th17 cells and IL-17 level in peripheral blood of patients infected by producing biofilm and non-producing biofilm bacteria and healthy person are respectively(0.59±0.18)%and(108.8±20.5)pg/ml,(0.58±0.18)%and(100.1±20.7)pg/ml,(0.55±0.17)% and(100.0± 21.4)pg/ml,they were not different among data from patients and healthy person,P>0.05,expressing ratios of Th17 cells and IL-17 level in bronchus alveolus washing-water of patients infected by producing biofilm and non-producing biofilm bacteria were respective (1.37±0.34)%,(157.4±30.8)pg/ml and(1.11±0.21)%,(136.2±24.3)mg/ml,the data between patients infected by producing biofilm and non-producing biofilm bacteria were distinctly different, P<0.05.Conclusion:
Bacteria biofilm can cause Th17 cell expressing ratio and IL-17 level to become high in infected part,this may be mechanism that infection become chronic.
