观察了旋毛虫肌幼虫在实验感染兔横纹肌内的分布 ,在舌肌中荷虫密度最高 ,顺次是咬肌、膈肌、肱三头肌、肩胛肌、肱二头肌、腓肠肌、胸大肌、肋间肌、腰肌 ,心肌中未发现幼虫 ,提示检查兔的舌肌、咬肌或膈肌发现肌幼虫的阳性率高。 The distribution of Trichinella spiralis larvae in the striated muscle of experimental rabbits was observed. The density of the larvae in the tongue muscle was the highest, followed by masseter, diaphragm, triceps, scapular, biceps, gastrocnemius and pectoralis major , Intercostal muscle, psoas muscle, myocardial larvae found, suggesting that check the rabbit’s tongue muscle, masseter muscle or diaphragm muscle larvae found positive rate.
