RESUMEN
Objective To determine chlamydia pneumoniae(Cpn) DNA and inclusion bodies in peripheral blood mononuclear cell(PBMC) of coronary heart disease.Methods The PBMC were isolated by low permeate hemolysis method.The presence of Cpn-DNA and inclusion bodies were determined by nest-PCR and directed immunofluorescence(DIF) in 150 cases with CHD and 55 non CHD(control group,CG).Results Cpn DNA positive rates were 32.7%(49/150) in CHD and 1.8%(1/55) in CG,simultaneity inclusion bodies were detected 13.3%(20/150) in CHD and 1.8%(1/55) in CG.The positivity rates of Cpn-DNA and inclusion bodies in CHD groups were significantly higher than those in control group.Conclusion Chlamydia pneumoniae DNA and inclusion bodies are present in PBMC among the significant proportion of CHD patients.PBMC sample can be collected easily and trustworthily.
