     DETAILED DESCRIPTION OF THE DISCLOSURE 
     Probiotic applicators and methods for using such applicators are provided herein. Such applicators and methods may be used to apply probiotic compositions to the oral cavity for treatment of conditions such as, for example, halitosis. 
     With reference to  FIGS. 1A and 1B , the present disclosure may be embodied as a probiotic applicator  10 . The probiotic applicator  10  includes a handle  12  and a head  14  affixed to the handle  12 . The head  14  is configured to scrape the surface of a tongue. For example, the head  14  may be shaped so as to scrape a surface when the device is moved across the surface. In some embodiments, the head  14  includes a scrubber  16  for additional scraping (e.g., scrubbing) effectiveness. The scrubber  16  may include features such as, for example, bristles, knobs, and/or ridges, or any other such features. For example, the scrubber may have one or more ridges, each having an edge configured to cleaning the surface of the tongue. In some embodiments, the scrubber may be flexible so as to at least partially conform to the surface of the tongue. The scrubber may be made from any material suitable to the particular application, such as, polypropylene, polyethylene, nylon, rubbers (e.g., silicone, latex, etc.), metal, sponge (natural or artificial), etc., or combinations of one or more such materials. 
     The head  14  of the probiotic applicator  10  includes a plurality of orifices  18  for dispensing a fluid onto the surface of the tongue. The fluid may be, for example, a probiotic composition (as further described below), such as a probiotic mixture in a coconut oil base. In some embodiments, the applicator is configured such that when pulled across the tongue, the scrubber cleans (scrapes, wipes, etc.) the surface of the tongue before fluid is dispensed onto the tongue via the orifices (i.e., the scrubber leads the orifices). With reference to  FIG. 3 , in some embodiments, such as applicator  100 , the orifices  118  may be positioned so as to dispense fluid into the scrubber  116  or through the scrubber  116 . 
     The applicator  10  has a reservoir  30  for containing the fluid. The reservoir  30  is in fluid communication with the plurality of orifices  18 . In some embodiments (see, e.g.,  FIG. 4 ), the reservoir  160  is located in the head  152  of the applicator  150 . In some embodiments, the reservoir  30  may be disposed in the handle  12 . In various embodiments, the reservoir may be disposed partially in both the head and the handle or elsewhere. In some embodiments such as the applicator  200  depicted in  FIG. 5 , the reservoir  230  makes up a portion of the handle  212 . Such a reservoir  230  may be removable from the applicator. For example, the reservoir  230  may be have screw threads  232  for attachment to corresponding screw threads of the handle  212 . In some embodiments, the reservoir is a part of the head. In some embodiments, channels  32 , such as, for example, tubes, are disposed through the head  14  to connect the reservoir to the orifices  18 . Such channels may be, for example, formed (e.g., molded, machined, etc.) into the material of the head. In other embodiments, the channels comprise one or more separate tubes that are disposed in the head. 
     The reservoir  30  may contain a fluid comprising a probiotic composition. The reservoir  30  may be removable such that the applicator  10  can be refilled with probiotic composition by replacement of the removable reservoir. For example, with reference to  FIG. 2 , the reservoir  30  may include screw threads  31  for attachment to corresponding screw threads within the applicator, for example, within the handle. The handle  12  may include a needle  34 , lance, blade, or other such device for piercing the reservoir in order to enable access to the probiotic composition. For example, the needle  34  may be positioned so as to pierce the reservoir  30  as the reservoir  30  is screwed into the handle  12 . In some embodiments, the reservoir is not pierced until the actuator is actuated by a user. In other embodiments, there is no need for piercing the reservoir. For example, the reservoir may have a port with a cap or other cover which is removed before insertion in the applicator. In another example, the reservoir is not removable and there is no need for piercing or otherwise covering the reservoir which is filled and installed within the applicator. In some embodiments, the reservoir is a chamber formed (e.g., molded, machined, etc.) within the applicator. 
     Some embodiments of the probiotic applicator  10  include an actuator  22  to allow probiotic composition to selectively flow from the reservoir  30  to the plurality of orifices  18 . The actuator  22  may be a button, a lever, a slide, a knob, or the like. In some embodiments, the reservoir  30  is configured to contain the probiotic composition under pressure. In this way, once the reservoir  30  is pierced, the probiotic composition will be biased to flow out through the plurality of orifices  18  without need for other motive force. In some embodiments, the actuator  22  is configured so as to stop the pressurized flow of probiotic composition unless/until the actuator  22  is actuated by a user. In some embodiments, the actuator  22  may be configured to allow a predetermined flow (e.g., flow for a pre-determined period of time, pre-determined volume, etc.) when actuated. In this way, the applicator  10  may be re-used by subsequent actuation of the actuator  22 . In other embodiments, the actuator  22  is configured to allow a flow of probiotic composition for so long as the actuator  22  is actuated (e.g., begin flowing when a button is depressed and ending flow when the button is released). In some embodiments, once actuated, the probiotic composition will flow unimpeded (e.g., flow until substantially empty). In some embodiments, the reservoir is a pouch configured to release probiotic composition when compressed (e.g., squeezed). For example, the pouch may be manually squeezed by the hand of a user when using the applicator. In other embodiments, the pouch may be mechanically squeezed by, for example, a piston, a lever, etc. In some embodiments, the pouch may be squeezed by pneumatic or hydraulic pressure. For example, a pressurized gas cartridge may be used to compress the pouch and displace a fluid (e.g., probiotic composition) contained in the pouch. 
     In another aspect, the present disclosure may be embodied as a method  300  for applying a probiotic composition to a tongue. The method  300  may use a probiotic applicator such any of the embodiments described above. The method  300  includes applying  306  the probiotic composition to the scraped  303  surface of the tongue. For example, the probiotic composition may be dispensed through orifices of the probiotic applicator. An actuator may be actuated  309  to cause the flow of probiotic (e.g., a button may be depressed). 
     In some embodiments, the surface of the tongue is scraped  303  using a scraping head of the probiotic applicator. Scraping  303  may include a unidirectional motion (e.g., back to front) or a back-and-forth (e.g., scrubbing) motion over the surface of the tongue. In some embodiments, the probiotic composition is applied after the surface of the tongue is scraped. In some embodiments, the probiotic composition is applied at the same time as the tongue is scraped (e.g., during the scraping motion). 
     Probiotics refer to microorganisms that are considered to provide health benefits when administered to a subject. The probiotic compositions of the present disclosure include bacteria from one or more of  Lactobacillus  species,  Akkermansia  species,  Ruminococcus  species,  Streptococcus  species,  Verrucomicrobia  species, and  Firmicutes  species.

To prepare the probiotic each bacteria type may be grown separately (such as by inoculation in appropriate broth, etc.) Following growth, bacteria may be isolated from the culture media, and bacteria may be lyophilized separately or may be combined in the desired amounts for a probiotic use. 
     In some embodiments, the disclosure provides a probiotic composition comprising, consisting essentially of, or consisting of the following bacteria:  Lactobacillus acidophilus; L. casei, L. reuteri; Akkermansia muciniphila, Ruminococcus bromii ; and strains of phylum  Verrucomicrobia  and phylum  Firmicutes , and optionally, may contain one or more of  Streptococcus thermophiles, Bifidobacterium breve, Escherichia coli  Nissle 1917,  Bifidobacterium lactis , and  Streptococcus salivarius . The CFUs in the probiotics are provided as per dose. 
     The amount of bacteria (individual type or all types) per dose may be 100 million to 1 billion bacterial cells (i.e., CFUs) and all values and ranges therebetween. In some embodiments, a dose may have more than 1 billion bacteria (individual type or all types). A dose may be a tablet, capsule, or a specified amount of the formulation in any form. In various embodiments, the bacteria (individual type or all types) per dose may be 100, 200, 300, 400, 500, 600, 700, 800, 900 million or 1 billion, 2 billion, 3 billion, etc. 
     The composition can be formulated for oral administration. The present oral compositions may be in the form of a chewable formulation, a dissolving or dissolved formulation, an encapsulated/coated formulation, multi-layered lozenges (to separate active ingredients and/or active ingredients and excipients), a slow release/timed release formulation, or other forms suitable for oral delivery known in the art. It may be in the form of a tablet, lozenges, pill, capsule, drops, paste or the like. The formulations may also be present as encapsulated or incorporated into micelles, liposomes, cyclodextrins, polymers and the like. 
     The probiotic formulations, including pediatric formulations, may be flavored (e.g., fruit flavored, such as cherry, strawberry, blueberry etc.) and may be in a variety of shapes or colors. 
     In an aspect, the present disclosure provides pharmaceutically acceptable compositions which comprise a therapeutically-effective amount of one or more of the bacterial species as described above, the cell therapies as described above, and/or the cytokines as discussed above, formulated together with one or more pharmaceutically acceptable excipients. In an aspect, the present disclosure provides pharmaceutically acceptable compositions which comprise a therapeutically-effective amount of one or more of the bacteria species as described above, formulated together with one or more pharmaceutically acceptable excipients and other therapeutically effective medications known in the art allowing for but not limited to combination therapies to improve overall efficacy of each individual therapeutic or to limit the concentration of either therapeutic to avoid side effects and maintain efficacy. The active ingredient and excipient(s) may be formulated into compositions and dosage forms according to methods known in the art. The pharmaceutical compositions of the present invention may be specially formulated for administration in solid or liquid form, including those adapted for the following: oral administration, for example, tablets, capsules, powders, granules, and aqueous or non-aqueous solutions or suspensions, drenches, or syrups, frozen or freeze-dried forms. The probiotic compositions may be present in a lyophilized form (i.e., freeze-dried form). The bacteria may be lyophilized individually or the entire probiotic composition may be lyophilized. 
     The term “therapeutically effective amount” as used herein refers to an amount of an agent sufficient to achieve, in a single or multiple doses, the intended purpose of treatment. Treatment does not have to lead to complete cure, although it may. Treatment can mean alleviation of one or more of the symptoms or markers of the indication. The exact amount desired or required will vary depending on the particular compound or composition used, its mode of administration, patient specifics and the like. Appropriate effective amount can be determined by one of ordinary skill in the art informed by the instant disclosure using only routine experimentation. Within the meaning of the disclosure, “treatment” also includes relapse, or prophylaxis as well as the alleviation of acute or chronic signs, symptoms and/or malfunctions associated with the indication. Treatment can be orientated symptomatically, for example, to suppress symptoms. It can be effected over a short period, over a medium term, or can be a long-term treatment, such as, for example within the context of a maintenance therapy. Administrations may be intermittent, periodic, or continuous. 
     The phrase “pharmaceutically acceptable” is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are suitable for use in contact with the tissues of the subject with toxicity, irritation, allergic response, or other problems or complications, commensurate with a reasonable benefit/risk ratio. 
     The phrase “pharmaceutically-acceptable excipient” as used herein refers to a pharmaceutically-acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, carrier, manufacturing aid (e.g., lubricant, talc magnesium, calcium or zinc stearate, or steric acid), solvent or encapsulating material, involved in carrying or transporting the therapeutic compound for administration to the subject. Each excipient should be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the subject. Some examples of materials which can serve as pharmaceutically-acceptable excipients include sugars, such as lactose, glucose and sucrose; starches, such as corn starch and potato starch; cellulose and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; gelatin; talc; waxes; oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols, such as ethylene glycol and propylene glycol; polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; esters, such as ethyl oleate and ethyl laurate; agar; buffering agents; water; isotonic saline; pH-buffered solutions; and other non-toxic compatible substances employed in pharmaceutical formulations. If desired, certain sweetening and/or flavoring and/or coloring agents may be added. Other suitable excipients can be found in standard pharmaceutical texts, e.g., in “Remington&#39;s Pharmaceutical Sciences”, The Science and Practice of Pharmacy, 19th Ed. Mack Publishing Company, Easton, Pa., (1995). 
     Excipients are added to the composition for a variety of purposes. Diluents increase the bulk of a solid pharmaceutical composition, and may make a pharmaceutical dosage form containing the composition easier for the patient and caregiver to handle. Diluents for solid compositions include, for example, microcrystalline cellulose (e.g., AVICEL®), microfine cellulose, lactose, starch, pregelatinized starch, calcium carbonate, calcium sulfate, sugar, dextrates, dextrin, dextrose, dibasic calcium phosphate dihydrate, tribasic calcium phosphate, kaolin, magnesium carbonate, magnesium oxide, maltodextrin, mannitol, polymethacrylates (e.g., EUDRAGIT®), potassium chloride, powdered cellulose, sodium chloride, sorbitol and talc. 
     Solid pharmaceutical compositions that are compacted into a dosage form, such as a tablet, may include excipients whose functions include helping to bind the active ingredient and other excipients together after compression. Binders for solid pharmaceutical compositions include acacia, alginic acid, carbomer (e.g., carbopol), carboxymethylcellulose sodium, dextrin, ethyl cellulose, gelatin, guar gum, hydrogenated vegetable oil, hydroxyethyl cellulose, hydroxypropyl cellulose (e.g., KLUCEL®), hydroxypropyl methyl cellulose (e.g., METHOCEL®), liquid glucose, magnesium aluminum silicate, maltodextrin, methylcellulose, polymethacrylates, povidone (e.g., KOLLIDON®, PLASDONE®), pregelatinized starch, sodium alginate and starch. 
     In liquid pharmaceutical compositions of the present invention, the bacterial species and any other solid excipients are dissolved or suspended in a liquid carrier such as water, water-for-injection, vegetable oil, alcohol, polyethylene glycol, propylene glycol or glycerin. Liquid pharmaceutical compositions may contain emulsifying agents to disperse uniformly throughout the composition an active ingredient or other excipient that is not soluble in the liquid carrier. Emulsifying agents that may be useful in liquid compositions of the present invention include, for example, gelatin, egg yolk, casein, cholesterol, acacia, tragacanth, chondrus, pectin, methyl cellulose, carbomer, cetostearyl alcohol and cetyl alcohol. Liquid pharmaceutical compositions of the present disclosure may also contain a viscosity enhancing agent to improve the mouth feel of the product and/or coat the lining of the gastrointestinal tract. Such agents include acacia, alginic acid bentonite, carbomer, carboxymethylcellulose calcium or sodium, cetostearyl alcohol, methyl cellulose, ethylcellulose, gelatin guar gum, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, maltodextrin, polyvinyl alcohol, povidone, propylene carbonate, propylene glycol alginate, sodium alginate, sodium starch glycolate, starch tragacanth and xanthan gum. A liquid composition may also contain a buffer such as gluconic acid, lactic acid, citric acid or acetic acid, sodium gluconate, sodium lactate, sodium citrate or sodium acetate. 
     Sweetening agents such as sorbitol, saccharin, sodium saccharin, sucrose, aspartame, fructose, mannitol and invert sugar may be added to improve the taste. Flavoring agents and flavor enhancers may make the dosage form more palatable to the patient. Common flavoring agents and flavor enhancers for pharmaceutical products that may be included in the composition of the present invention include maltol, vanillin, ethyl vanillin, menthol, citric acid, fumaric acid, ethyl maltol and tartaric acid. Preservatives and chelating agents such as alcohol, sodium benzoate, butylated hydroxy toluene, butylated hydroxyanisole and ethylenediamine tetraacetic acid may be added at levels safe for ingestion to improve storage stability. 
     The present compositions can be used to treat oral health conditions including halitosis. The compositions can also be used to improve immune response, oral hygiene, including bone density and treatment of bad breath. Halitosis is also a characteristic symptom of periodontal disease, and is caused by the production of volatile sulphur compounds (VSCs), such as hydrogen sulphide (H 2 S) and methyl mercaptan, by sulfate-reducing bacteria. The major cultivatable periodontal opportunistic pathogens,  Porphyromonas gingivalis  (Pg),  Fusobacterium nucleatum  (Fn) and  Tannerella forsythia  (Tf), are reported to have produced H 2 S in an in vitro system as measured by gas chromatography. These pathogens colonize the surface of tongue play significant role in H 2 S production. In 80 to 90 percent halitosis cases involve bacteria from the oral cavity. Here we showed in vitro cell culture model and P00519 bacterial formulation to reduce H 2 S production ( FIG. 7 ). 
     The subject may be any animal, including human and non-human animals. Non-human animals includes all vertebrates, e.g., mammals and non-mammals, such as non-human primates, sheep, dogs, cats, cows, horses, chickens, amphibians, and reptiles, although mammals are preferred, such as non-human primates, sheep, dogs, cats, cows and horses. The subject may also be livestock such as, cattle, swine, sheep, poultry, and horses, or pets, such as dogs and cats. 
     Some specific embodiments of the present disclosure are provided below. 
     A lyophilized probiotic composition comprising, consisting essentially of or consisting of two or more or all of:  Lactobacillus acidophilus  (10 8  CFUs);  L. casei  (10 8  CFUs);  L. reuteri  (10 8  CFUs);  Akkermansia muciniphila  (10 7  CFUs);  Ruminococcus bromii (10 7  CFUs);  Streptococcus salivarius  (10 9  CFUs); and strains of phylum  Verrucomicrobia  and  Firmicutes  (10 6  CFUs). 
     In some embodiments, the present probiotic compositions may be used in the treatment of halitosis. For example, P00519 may be used directly in the oral cavity for the treatment of halitosis. The probiotic may be used by itself in the form of a rinse, paste, liquid, gel or chewable or other tablets, or may be incorporated into toothpastes, other rinses (such as dental or oral mouthwashes), oral or dental appliances, or any other device that may come in contact with the oral cavity. 
     The probiotic composition can be formulated for administration using the applicator described above. For example, the composition may be formulated as a liquid that can be contained in the reservoir, flowed through the channels, and dispensed by way of the plurality of orifices. Some compositions have a coconut oil liquid in which the probiotic mixture is mixed. One or more other liquids may be used in addition to, or instead of, coconut oil. The probiotic formulations, including pediatric formulations, may be flavored (e.g., fruit flavored, such as cherry, strawberry, blueberry, etc.) and/or may be in a variety of colors. 
     The present applicator and method can be used with probiotic compositions to treat oral conditions including halitosis. The compositions can also be used to improve oral hygiene and treatment of bad breath. Halitosis is also a characteristic symptom of periodontal disease, and is caused by the production of volatile sulphur compounds (VSCs), such as hydrogen sulphide (H 2 S) and methyl mercaptan, by sulfate-reducing bacteria. The major cultivatable periodontal opportunistic pathogens,  Porphyromonas gingivalis  (Pg),  Fusobacterium nucleatum  (Fn) and  Tannerella forsythia  (Tf), are reported to have produced H 2 S in an in vitro system as measured by gas chromatography. These pathogens can colonize the surface of tongue and play a significant role in H 2 S production. In 80 to 90 percent of halitosis cases, bacteria from the oral cavity are involved.  FIG. 7  shows results of an in vitro cell culture model and P00519 bacterial formulation to reduce H 2 S production (further described below). 
     Halitosis, bad breath or oral malodor are all synonyms for the same pathology. Halitosis has a large social and economic impact. For the majority of patients suffering from bad breath, it causes embarrassment and affects their social communication and life. Moreover, halitosis can be indicative of underlying diseases. Halitosis is also a characteristic symptom of periodontal disease, and is caused by the production of volatile Sulphur compounds (VSCs), such as hydrogen sulphide (H 2 S) and methyl mercaptan, by sulfate-reducing bacteria. Importantly, the major cultivatable periodontal opportunistic pathogens,  Porphyromonas gingivalis  (Pg),  Fusobacterium nucleatum  (Fn) and  Tannerella forsythia  (Tf), are reported to have produced H 2 S in an in vitro system as measured by gas chromatography. These pathogens colonize the surface of tongue play significant role in H 2 S production. In 80 to 90 percent halitosis cases involve bacteria from the oral cavity. Here we used in vitro cell culture model and P00519 bacterial formulation to determine whether cocktail of certain bacteria can reduce H 2 S production. 
     Measurement of Hydrogen Sulfide from Bacteria. 
     Probiotic composition P00519 was tested using two major bacteria  Porphyromonas  spp and  Fusobacterium  spp involved in halitosis and periodontal diseases. Bacteria were cultured in broth medium until they reached late log growth phase, and the concentration of all strains was then adjusted to 10 8 -10 9  cell/ml. Subsequently, the bacterial suspension was used for detecting H 2 S production in bacterial biofilm culture and in presence of oral epithelial cells. 
     Calorimetric method: The bismuth sulfide method was modified by using a 5 mM concentration of bismuth(III)chloride. Bacteria were diluted in peptone solution to 10 9  cells/mL. Aliquots (100 ml) of the bacterial suspension were mixed with an equal amount of newly prepared bismuth solution (0.4 M triethanolamineHCl, pH 8.0; 10 mM bismuth(III)chloride; 20 mM pyridoxal 5-phosphate monohydrate, 20 mM EDTA and 40 mM L-cysteine) in microtiter plates. H 2 S production was monitored by detecting black BS is precipitated. Intensity of black precipitate was visually scaled, from no color production (0) to maximum black color production after 24 hours. 
     H 2 S production in epithelial cell and bacterial co-culture model: Human oral epithelial origin cell line OKF6 was used in this study. The cells were cultured in Keratinocyte-Serum Free Medium supplemented with 50 μg/ml bovine pituitary extract, 5 ng/ml epidermal growth factor in humidified atmosphere of 5% CO 2  at 37° C. The bacterial species tested for H 2 S-producing capacity were  Porphyromonas  spp,  Fusobacterium  spp, and probiotic cocktail (P00519). The species were grown on appropriate agar plates under optimal conditions. Desired concentration of theses bacteria or P00519 (10 8  cfu/ml) was added to 2 M epithelial cells in 25 ml Corning Primaria Tissue Culture Flasks and incubated for 24 hours as mentioned before. Handheld Hydrogen Sulfide (H 2 S) Gas Detector with range from 0 to 500 ppm was used for H 2 S production. 
     Results: 
     In calorimetric method bacterial hydrogen sulfide (H 2 S) production from cysteine measured with colorimetric methods in microtiter plate format, recorded as black bismuth sulfide precipitation formation. The most rapid H 2 S production was seen for  Porphyromonas  spp and  Fusobacterium  spp. reaching the maximum color production then the probiotic group and controls. 
     Further, we used H 2 S as marker of production of volatile Sulphur compounds in association with oral epithelial cells. The results indicated that when cell were co-cultured with  Porphyromonas  spp and  Fusobacterium  spp there was higher production of H 2 S whereas when the cells were co-cultured with probiotic cocktail (P00519) and without bacteria there was significantly less production of H 2 S ( FIG. 7 ). This results indicated that  Porphyromonas  and  Fusobacterium  can utilize the components of media and epithelial cells to produce H 2 S whereas use of the exemplary probiotic cocktail does not produce volatile sulphur compounds. These data indicate the present probiotic compositions can be used for the prevention and/or treatment of bad breath.
