The molten homogeneous mixture is then poured into conveniently sized molds, allowed to cool, and to solidify.
 The inactivated probiotic bacteria of the present invention may be formulated for vaginal administration. Pessaries, tampons, creams, gels, pastes, foams or sprays, may contain agents in addition to the bacteria, such carriers, known in the art to be appropriate.
 In some embodiments, inactivated probiotic bacteria are formulated for delivery by inhalation. As used herein, the term"aerosol"is used in its conventional sense as referring to very fine liquid or solid particles carries by a propellant gas under pressure to a site of therapeutic application. The term"liquid formulation for delivery to respiratory tissue"and the like, as used herein, describe compositions comprising inactivated probiotic bacteria with a pharmaceutically acceptable carrier in flowable liquid form. Such formulations, when used for delivery to a respiratory tissue, are generally solutions, e. g. aqueous solutions, ethanolic solutions, aqueous/ethanolic solutions, saline solutions and colloidal suspensions.
[00$2] In general, aerosolized particles for respiratory delivery must have a diameter of 12 microns or less. However, the preferred particle size varies with the site targeted (e. g, delivery targeted to the bronchi, bronchia, bronchioles, alveoli, or circulatory system). For example, topical lung treatment can be accomplished with particles having a diameter in the range of 1.0 to 12.0 microns. Effective systemic treatment requires particles having a smaller diameter, generally in the range of 0.5 to 6.0 microns. Thus, in some embodiments, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about
90%, or more, of an aerosolized formulation comprising inactivated probiotic bacteria for delivery to a respiratory tissue is composed of particles in the range of from about 0.5 to about
12 micrometers, from about 0.5 to about 6 micrometers, or from about 1.0 to about 12 micrometers.
 The formulation for delivery to a respiratory tissue may be provided in a container suitable for delivery of aerosolized formulations. U. S. Patents 5,544, 646 ; 5,709, 202;

In some embodiments, the invention provides a container, which may be a disposable container, having at least one wall that is collapsible or movable upon application of a force, wherein at least one wall has an opening. A porous membrane having pores in a range of from about 0.25 microns to about 6 microns covers the opening. The container comprises a flowable liquid formulation comprising inactivated probiotic bacteria. Upon application of a force, the flowable liquid formulation is forced through the pores in the membrane and is aerosolized. The container may be provided in any known configuration, e. g. , a blister pack. The container may be provided together with an aerosol delivery device, such that the aerosolized formulation exits the container and proceeds through a channel in an aerosol delivery device and into the respiratory tract of an individual.
 When a pharmaceutical aerosol is employed in this invention, the aerosol contains inactivated probiotic bacteria, which can be dissolved, suspended, or emulsified in a mixture of a fluid carrier and a propellant. The aerosol can be in the form of a solution, suspension, emulsion, powder, or semi-solid preparation. Aerosols employed in the present invention are intended for administration as fine, solid particles or as liquid mists via the respiratory tract of a patient. Various types of propellants known to one of skill in the art can be utilized.
Examples of suitable propellants include, but is not limited to, hydrocarbons or other suitable gas. In the case of the pressurized aerosol, the dosage unit may be determined by providing a value to deliver a metered amount.
[OOS5] Administration of formulation comprising inactivated probiotic bacteria can also be carried out with a nebulizer, which is an instrument that generates very fine liquid particles of substantially uniform size in a gas. Preferably, a liquid containing the inactivated probiotic bacteria is dispersed as droplets. The small droplets can be carried by a current of air through an outlet tube of the nebulizer. The resulting mist penetrates into the respiratory tract of the patient.
 A powder composition containing inactivated probiotic bacteria, with or without a lubricant, carrier, or propellant, can be administered to a mammal in need of therapy. This embodiment of the invention can be carried out with a conventional device for administering a powder pharmaceutical composition by inhalation. For example, a powder mixture of the compound and a suitable powder base such as lactose or starch may be presented in unit dosage form in for example capsular or cartridges, e. g. gelatin, or blister packs, from which the powder may be administered with the aid of an inhaler.
