endogenous infection

CONCLUSIONS Endogenous infection is the main reason of hospital infection ; heavy primary disease , invasive examination , hormone application and irrational use of antibiotics are the main risk factors of hospital infection .

结论内源性感染是我院医院感染的主要部分：基础病严重、侵袭性操作、激素应用及不合理使用抗菌药物等是造成医院感染的主要危险因素；

OBJECTIVE To evaluate the role of endogenous infection route in the pathogenesis of ventilator-associated pneumonia ( VAP ) by molecular epidemiological methods , in order to explore and develop new prophylactic procedures of VAP .

目的用分子流行病学方法研究呼吸机相关肺炎（VAP）内源性感染途径在VAP发病机制中的作用，为探索和发展全新的VAP预防措施提供理论依据。

Secondly , long-term use of antibiotic declines the immunity of animal , in addition , causes endogenous infection to animal too .

其次，长期使用抗生素造成畜禽机体的免疫力下降；

Results The infection occurred more often in patients in mid-late stage ( 83.6 % ), with endogenous infection being 43.8 % and the infected regions were chiefly in the respiratory tract ( 59 % ) .

结果感染以中晚期患者为多，占83.6%，内源性感染为43.8%；感染部位以呼吸道为主，占59%；

Most of VVC patients were endogenous infection ( pathogenic origin from the vagina or anus ), a small number of them were exogenous ( sexually transmitted ) infection . Conclusions : 1 .

大多数VVC患者为内源性感染（致病菌起源于阴道内或肛周），少数为外源性（性传播）感染。

Personal hygiene practices and sexual behaviors among married women in the study were good in general . In terms of the prevalence of endogenous infection , there were statistical differences between women who had different frequencies of rinsing their vulvae and taking bath ;

大多数妇女个人生活卫生习惯和性卫生行为良好，清洗外阴和洗澡频度不同的妇女内源性感染率差异具有统计学意义；

In schistosomiasis transmission-interrupted provinces in China , the endogenous source of infection has been basically cleared , and the exogenous source of infection is considered as a major threat .

当前我国血吸虫病传播阻断省份内源性传染源已基本清除，外源性传染源成为主要威胁；

The reverse endogenous stomach-lower respiratory tract infection route was verified in 15 cases ( among them 14 cases were late-onset VAP ) of the total 52 VAP patients by PFGE analysis , with the incidence of 28.8 % .

病原菌的PFGE同源性分析表明ICU中52例VAP患者有15例（其中14例为晚发性VAP）存在胃腔→下呼吸道逆向内源性感染途径，占VAP发病总数的288%；
