摘要
目的在标本作细菌培养前涂片镜检,分析标本涂片与培养结果的相关性。方法将临床送检的358例标本进行涂片镜检和细菌培养,将镜检结果与培养结果进行比较分析结果358例标本中培养阳性的有127例,其中革兰氏阳性球菌24例,革兰氏阴性杆菌56例,真菌47例。痰标本、尿标本、胸腹水标本、其它标本的涂片与培养结果符合率分别为74.2%、73.9%、97.2%、93.8%。经χ2检验痰标本、尿标本、胸腹水标本、其它标本的涂片与培养结果符合率无显著性差异(χ2值均分别为0.014、0.017、0、0,P值均<0.05)。结论标本培养前的涂片镜检减少了培养结果的误差,有效的提高了标本培养阳性检出率。
Objective Samples were detected by the examination of bacteria in smear before detected by the culture of bacteria, and analyzed the relativity of the two results. Methods 358 specimens were detected by the methods of the examination of bacteria in smear and the culture of bacteria, and compare the two results. Results There are 127 positive cases of the examination in the culture of bacteria in the 358 cases, in which gram positive coccus is 24, gram negative coccus is 56, epiphyte is 47. The accord rates between the results of smear and culture of the specimens of sputum, urine, hydrothorax and ascites, and others separately is 74.2 % ,73.9 %, 97.2%,93.8%. By X^2 testing,there is no significant difference between the accord rates of the results of smear and culture of the speeimens of sputum, urine, hydrothorax and ascites, and others（The X^2 separately is 0.014,0.017,0,0, P 〈 0.05） o Conclusion The examination of bacteria in smear before culturing decrease the errors of the results of culturing and effectively increase the positive detectable rates of specimens.
