Antibacterial function of body wall was conducted by the following way: microorganism was directly resisted through the change of cuticle, such as incrassation of up-cuticle protuberance and increasing length of micro-floccus in the up-cuticle dissociation surface; exudation function of large granular orthochromatic mucous cells and reticulation mucous cells in the epidermis could be enhanced when the Eisenia fetida was induced by E. coli. Moreover, the mucus that contained compound substance of mucopolysaccharide and protein could make the bactericidal function or dilute the microorganism on the surface of earthworm, which could protect earthworm from invasion of microorganism; the content of neutral mucopolysaccharide of antibacterial function could be increased according with the exudation increment of small granular proteinaceous cells in the epidermis, which could resist bacteria invading into the epidermis of earthworm.

结果表明：蚯蚓的体壁主要是通过以下途径来抗细菌的侵袭：一是通过角质层的变化(如上胶层突起的增厚、上角层游离面中微绒毛的变长等)直接抵抗微生物的入侵；二是增加表皮中大颗粒粘液细胞和网状细胞的分泌功能，分泌出大量含有粘多糖蛋白液体复合物的粘液，在蚯蚓体表对细菌进行稀释或者起到直接杀菌的作用；三是通过增加小颗粒蛋白细胞的分泌作用，在蚯蚓的表皮中分泌出更多的抵抗疾病的中性粘多糖，从而抵抗进入蚯蚓体表内的细菌。

While protamine inhibit or kill bacteria, bacteria are induced a variety of mechanisms to resist it.

And they found that bdelloid rotifers can shake the infection by drying out, drifting away and then rehydrating once they land someplace moist but fungus-free.

他们发现蛭形轮虫能够通过自身风干，然后飘走来摆脱细菌，等降落到潮湿而没有细菌的地方后，它们会再次补水。

First, we found that after exposure to 60℃ for 5 and 30 min ,culturable L. pneumophila concentration reduced 4 and 6 log CFU/mL, and the loss of cell membrane integrity was 56 % and 83 %, respectively. However, the total concentration was not affected. These results indicate heat exposure decreases the culturability of L. pneumophila significantly.Second, heated L.

结果显示，退伍军人菌（108 cells/ml）於60℃受热5分钟与30分钟后，可培养浓度分别下降了4 log CFU/ml与6 log CFU/ml，而细胞膜完整性则分别下降56 %与83 %，但未造成总细菌浓度之改变，故可知受热60℃主要影响细菌的可培养性。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

通过对日本凹顶藻以不同溶剂的粗提、乙醇提取物的极性分离、不同极性的薄层层析和多糖的提取，进行抗菌试验的研究，发现95%乙醇和V甲醇：甲苯为3∶1的提取的活性物质具有较强的抗姬松茸的病原细菌活性，乙酸乙酯相对病原细菌的抑菌强于乙醇的粗提物，而水相基本无抑菌效果，乙酸乙酯相的两个带（Rf0.57、Rf0.63）浓度为0.1g/ml具有较强抗姬松茸病原细菌的活性，对假单孢杆菌抑菌圈达到19.3mm，水相层析带的抑菌活性较弱，多糖的粗提物配成0.25g/g的水溶液对姬松茸病原真菌有较好的抑菌效果对黑曲霉、桔青霉和绿色木霉的抑菌圈分别达到10.8 mm、7.9 mm、5.3 mm。
