近年来结核病发病率有所回升,从而增加了医务人员因职业系正而被感染的机会.为评价卡介苗对医务人员的免疫效果,1994年对24名结核菌素(PPD)试验阴性的医务人员接种了卡介苗.接种后2个月复查PPD试验阳性率为100%,硬结平均直径为12.29上4.45mm;接种后一年复查20人.PPD试验阳性维持率达100%,硬结平均直径为9.5土3.76mm.接种部位多数形成卡痕,提示卡介苗对成年易感者仍具有良好的免疫效果.
In recent years, the incidence of tuberculosis has risen, which increases the chances of medical staff being infected due to occupational diseases.In order to evaluate the immune effect of BCG on medical staff, 24 medical staff who tested negative for tuberculin (PPD) BCG was inoculated 2 months after inoculation, the positive rate of PPD test was 100%, and the average diameter of induration was 4.45mm on 12.29; one year after inoculation, 20 patients were reexamined.The positive rate of PPD test was 100% and the average diameter of induration was 9.5% 3.76mm. The majority of inoculation sites formed card marks, suggesting that BCG still has a good immune response to adult susceptible.
