Sterile larval excretion/secretion (ES) exhibited antibacterial activity against some species of bacteria. They were shown to inhibit the growth of Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis Gram-negative bacteria Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae and Fungi Geotricum candidum and Aspergillus fumigatus thus exhibited limited inhibitory effect towards Gram-positive bacteria Streptococcus pyogenes and Staphylococcus epidermidis and Gram-negative Proteous vulgaris and Fungi Syncephalastrum racemosum, Candida albicans, that effect was slowed down when challenged with secretion on a solid media but no zone of complete inhibition was detectqd. Growth inhibiting activity was determined in liquid growth media using the Gram-positive, Gram-negative bacterial and fungal strains as indicator organisms.
无菌幼虫排泄/分泌物（ES）对某些细菌种类表现出抗菌活性。它们被证明能抑制革兰氏阳性菌金黄色葡萄球菌和枯草芽孢杆菌、革兰氏阴性菌铜绿假单胞菌、大肠杆菌和肺炎克雷伯菌，以及真菌白地霉和烟曲霉的生长，因此对化脓性链球菌和表皮葡萄球菌等革兰氏阳性菌、普通变形杆菌等革兰氏阴性菌以及总状共头霉、白色念珠菌等真菌表现出有限的抑制作用，当在固体培养基上用分泌物进行挑战时，这种抑制作用会减缓，但未检测到完全抑制区。使用革兰氏阳性、革兰氏阴性细菌和真菌菌株作为指示生物，在液体生长培养基中测定生长抑制活性。
