摘要

发现双翅目头角虫雌性生殖副腺的分泌物对大肠杆菌有抗菌作用。至少有两个分子量分别为15.5和4.7 kDa的碱性多肽被确定为具有这种活性。此外，15.5 kDa蛋白对许多革兰氏阳性和阴性菌株都有活性。溶菌酶活性也存在于分泌物中。

The female reproductive accessory glands of the medfly Ceratitis capitata: Antibacterial activity of the secretion fluid

Secretion from female reproductive accessory glands of the dipteran Ceratitis capitata was found to have antibacterial properties against E. coli. At least two basic polypeptides with mol. wt 15.5 and 4.7 kDa respectively, were identified as responsible for such activity. Furthermore, the 15.5 kDa protein is active against a number of Gram-positive and -negative bacterial strains. Lysozyme activity is also present in the secretion.
