目的 为了探讨抗体包裹细菌 ( ACB)对院内下呼吸道感染的诊断价值。方法 痰中病原菌定量培养、鉴定及荧光免疫法检测 ACB及其抗体类型。结果 ACB在含致病菌标本中阳性率为 64 .4 % ;在非致病菌标本中阳性率为 11.9% ,二者差异明显。结论 ACB与痰中致病菌 (浓度 )密切相关 ,对于院内下呼吸道感染的诊断、治疗具有重要临床意义
Objective To investigate the value of antibody-coated bacteria (ACB) in the diagnosis of nosocomial lower respiratory tract infection. Methods Sputum pathogens quantitative culture, identification and immunofluorescence assay ACB and antibody types. Results The positive rate of ACB in pathogenic bacteria was 64.4%. The positive rate of ACB in non-pathogenic bacteria was 11.9%. The difference was significant. Conclusions ACB is closely related to pathogens (concentration) in sputum, and has important clinical significance for the diagnosis and treatment of nosocomial lower respiratory tract infection
