Forty-four dogs were used. In experimental animals, Serratia marcescens inoculated cloth were placed on the entrance or exist side before shooting, while in control animals no inoculated cloth was placed. Bullet wounding was carried out to both hind legs from a distance of 20 metres. 5.56 mm calibre bullet was used. The impact velocity was 919 m/s or 716 m/s. Bacteriological examination was made immediately or 6 hrs after the shot. The experimental studies showed that primary bacterial contamination of bullet wounds could be resulted immediately after the shot. And it has been verified that the main mechanisms of primary bacterial contamination were two: (1) The bacteria were sucked into the wound by negative pressure of the temporary cavity at both entrance and exit sides. (2) At entrance side, in addition, bacteria could be further carried into the wound tract by contaminated bullet itself.
使用了44只狗。在实验动物中，射击前将接种粘质沙雷氏菌的布放在入口或出口侧，而对照动物不放置接种布。从20米的距离对两条后腿进行枪击。使用的是5.56毫米口径子弹。撞击速度为919米/秒或716米/秒。枪击后立即或6小时后进行细菌学检查。实验研究表明，枪击后子弹伤口可立即发生原发性细菌污染。并且已经证实原发性细菌污染的主要机制有两个：（1）细菌通过入口和出口侧临时腔的负压被吸入伤口。（2）此外，在入口侧，细菌可被受污染的子弹本身进一步带入伤口通道。
