Abstract: The present invention relates to an immunomodulator for the prevention or treatment of an allergic disease caused by house dust mite-derived allergens. Particularly, the present invention provides an immunomodulatory pharmaceutical composition comprising as an effective ingredient a bacteria extracellular vesicle containing an allergens derived from North American house dust mite or European house dust mite, and a preparation method therefor.

Abstract: Provided is a composition for the treatment of pregnancy-associated diseases, and more particularly, to a pharmaceutical composition for the prevention or treatment of premature delivery or breast cancer. The pharmaceutical composition including extracellular vesicles derived from bacteria belonging to the genus Bacillus as an active ingredient may induce pregnancy or prevent premature delivery of pregnant women, may be used to prevent or treat pregnancy-associated diseases such as breast cancer, and may be used to diagnose a risk of premature delivery by measuring the amount of extracellular vesicles derived from bacteria belonging to the genus Bacillus in pregnant women.

Abstract: The present invention relates to a method for predicting causative factors (bacteria) of serious bacterial infectious diseases in a clinical sample containing bacteria-derived nano-sized extracellular vesicles, that is, nanovesicles, through the analysis of the genes contained in the nanovesicles. According to the present invention, information on bacteria of serious bacterial infection can be provided, a causative factor of the bacterial infection can be predicted, and the resistance of the bacteria to antibiotics can be predicted.
