【摘要】 目的了解安庆市新生儿接种卡介苗质量,为考核免疫规划工作提供参考依据。方法对新生儿接种BCG 12周后进行卡介菌纯蛋白衍生物试验。结果安庆市城乡BCG接种率均>95%,卡痕率分别为97.48%9、7.04%,BCG-PPD试验阳转率分别为96.2%、69.8%,差异有统计学意义(χ2=56.873,P<0.01)。卡痕的平均直径与BCG-PPD试验平均直径呈正相关(r=0.418,P<0.01),卡痕直径≥3mm者BCG-PPD试验阳转率为90.6%。结论卡痕直径≥3mm,可作为评价卡介苗接种是否成功的参考指标之一。更多还原

【Abstract】 Objective To understand the quality of BCG (Bacillus Calmette-Guerin) inoculations on neonates,so as to provide the evidence for the immune program. Methods BCG-PPD(Purified Protein Derivative of BCG) tests were conducted in the 12-week neonates that had inoculated BCG. Results The inoculating rate of BCG and the BCG scar rate were both higher than 95%,the BCG-PPD positive rates were 96.2% in urban and 69.8% in rural,and there was a significant difference between them(χ2=56.873,P<0.01).The average diameter of scar was positively correlated with the average diameter of BCG-PPD test(r=0.418,P<0.01),and the positive rate of BCG-PPD tests was 90.6% with the diameters of scars≥3 mm.Conclusions The diameter of scar≥3 mm can be one of the referenced index of successful of the inoculation of BCG.更多还原
