Using Indirect Immunofluorescence Antibody test(IFA), blood routine, C-reactive Protein (CRP), and High-sensitivity C-reactive Protein(hsCRP), we detected nine respiratory pathogens (Respiratory syncytial virus; Influenza A virus; Influenza B virus; Parainfluenza virus; Adenovirus; Mycoplasma pneumoniae; Chlamydia pneumoniae; Legionella pneumophila type 1; Rickettsia Q) in all patients and analyzed their distribution and correlation. The patients were divided into three groups [Respiratory Syncytial Virus Immunoglobulin M(RSV-IgM) positive group A, Mycoplasma Immunoglobulin M(MP - IgM) positive group B, antibody - negative group with elevated hsCRP, 40 patients each]. We compared differences in hsCRP, platelet count, White Blood Cells(WBC), and Neutrophil(NE) among the groups.Results: We conducted a systematic sorting and analysis of variables exhibiting significant differences. The results of the multivariate logistic regression analysis indicated that inflammatory markers, including white blood cell count (WBC) (OR 3.85, 95% CI: 1.116– 1.623), neutrophils (NE) (OR 2.26, 95% CI: 1.091– 1.312), high-sensitivity C-reactive protein (HsCRP) (OR 1.95, 95% CI: 1.068– 14.640), lymphocytes (OR 1.30, 95% CI: 1.045– 1.134), platelet count (OR 1.34, 95% CI: 1.625– 2.760), and C-reactive protein (CRP) (OR 3.80, 95% CI: 1.232– 2.379), were significantly associated with the presence of pathogenic bacteria.Conclusion: There was significant correlation between inflammatory markers and pathogenic bacteria in patients with lower respiratory tract infection in Xinjiang region.Keywords: correlation, inflammatory markers, lower respiratory tract infection, pathogenic bacteria
