Provided are vesicles derived from Enhydrobacter bacteria and a use thereof, and the inventors experimentally confirmed that the vesicles were significantly reduced in clinical samples obtained from patients with pancreatic cancer, cholangiocarcinoma, breast cancer, ovarian cancer, lymphoma, myocardial infarction, cardiomyopathy, atrial fibrillation, variant angina, liver cirrhosis, and diabetes, compared with a normal individual, and that when vesicles isolated from the strain were administered, the secretion of inflammatory mediators caused by pathogenic vesicles, such as E. coli-derived vesicles, was significantly inhibited. Therefore, it is expected that the vesicles derived from Enhydrobacter bacteria according to the present invention can be effectively used for a method of diagnosing pancreatic cancer, cholangiocarcinoma, breast cancer, ovarian cancer, lymphoma, myocardial infarction, cardiomyopathy, atrial fibrillation, variant angina, liver cirrhosis, or diabetes, and for developing a composition for preventing, alleviating or treating the diseases.

An oral dissolving film containing nano- or micro-encapsulated bioactive material and methods of forming the film. The film may be prepared by dispensing a mixture of a film-forming agent, a crosslinking agent, a solution of nano- or micro-encapsulated bioactive material, and a photoinitiator into a plurality of wells in a tray using a 3D printer. The dispensed material is exposed to radiation in order to crosslink the material and form a film.

Disclosed are methods of treating individuals with yeast-based immunotherapy who have been preselected as being sensitive to type I interferons, as well as methods for selecting individuals for treatment with yeast-based immunotherapeutic compositions and methods for enhancing or improving an individual's response to yeast-based immunotherapy, based on the individual's sensitivity to type 1 interferons (T1IFNs).

The invention provides compositions comprising bacterial strains for treating and preventing inflammatory and autoimmune diseases.

A novel consortium used as potent vaccine for treating of enteric fever, comprised of isolated Outer Membrane Vesicles (OMVs) taken from two different strains of typhoidal Salmonella species.

Bacterial strains are provided having at least one of a reduced size, a sialic acid coat, inducibly altered surface antigens, and expression of PD-L1 or CTLA-4 antagonists and/or tryptophanase. The bacteria may have improved serum half-life, increased penetration into tumors, increased tumor targeting and increased antitumor activity. The bacteria are useful for delivery of therapeutic agents that treat of neoplastic diseases including solid tumors and lymphomas.

The present invention relates to Brachyspira hyodysenteriae strains and their use in diagnosis or treatment. In addition, the invention provides a vaccine against diarrheal disease, in particular swine dysentery.

The present invention is directed to virus-like particles (VLPs) which are engineered to present epitopes from Staphylococcus aureus (SA), preferably autoinducing peptides (AIPs) which regulate quorum-sensing dependent virulence in this pathogen, or epitopes from SA toxins and leukocidins. These VLPs may be used to provide immunogenic compositions and efficacious vaccines. In a mouse model of SA dermonecrosis, vaccination with AIP-containing VLPs or SA toxin-containing VLPs induces protective immunity to limit the pathogenesis of SA infection and promote bacterial clearance.

Bordetella pertussis iron receptor proteins or portions thereof (e.g., one or more extracellular domains), alone or spliced into B. pertussis scaffold proteins (e.g., fimbrial or flagellin), are provided and can be used in acellular vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals. In addition, Bordetella species grown under iron-starved conditions are provided and can be used in whole cell vaccines to protect against pertussis or other Bordetella diseases in humans and non-human mammals.

Disclosed are methods of treating individuals with yeast-based immunotherapy who have been preselected as being sensitive to type I interferons, as well as methods for selecting individuals for treatment with yeast-based immunotherapeutic compositions and methods for enhancing or improving an individual's response to yeast-based immunotherapy, based on the individual's sensitivity to type 1 interferons (T1IFNs).
