Abstract
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.
