新生儿沙眼衣原体感染的形态学检查

MORPHOLOGICAL DECTECTION OF CHLAMYDIA TRACHOMATIS IN NEONATES

沙眼衣原体常引起新生儿结膜炎 ,本文采用新生儿下脸结膜刮片行直接涂片后Giemsa染色镜检和细胞培养检测沙眼衣原体 (CT) ,直接涂片后Giemsa染色镜检的阳性率为 71 2 % ( 37 5 2 ) ,没有细胞培养敏感 (P <0 .0 5 )。但直接涂片后Giemsa染色镜检对新生儿CT感染的检测的特异性和细胞培养相同 ,为 1 0 0 %。因此 。

Conjunctivitis in mewborns was often caused by Chlamydia tyachomatis (CT). For dectecting CT, atotal of 52 conjunctival scrapings taken from neonates with conjunctivitis in Chongqing children hospital during 1997.10 1989.9 were tested by the McCoy cell culture and Giemsa staining. The results showed that the sensitivity of Giemsa staining was 71 2% (35/52), and was obviously lower than that of cell culture (P<0.05). But the specificity of Giemsa staining and cell culture were same (100%). Therefore, we consider Giemsa staining was a simple and rapid methodin dectection of C. trachomatis.
