Description

  The present invention relates to Streptococcus mutans, Streptococcus sobrinus and Streptococcus sobrinus, which are causative bacteria of dental caries (caries) which are oral diseases, and Actinomyces Actinomyces viscosus, Porphyromonas gingivalis, Fusobacterium nucleatum, Streptococcus pyogenes of Streptococcus pyogenes, the causative agent of inflammation, and the cause of yellow poisoning of food poisoning The present invention relates to an antibacterial agent comprising an extract derived from ascomycetes or basidiomycetes that suppresses the growth of Staphylococcus aureus, an oral composition containing the same, and a food and drink.

  Hundreds of types of bacteria are present in the oral cavity, and they are inhabited by forming their own bacterial flora with dental plaque, gingival crevice, saliva, etc., and are closely related to the causes of caries and periodontal disease.

  Streptococcus mutans (Streptococcus sobrinus), which has strong cariogenic properties, synthesizes sticky polysaccharides from sucrose in food and drink. Among the polysaccharides, various bacteria such as mutans streptococci breed and form dental plaques. Moreover, since mutans streptococci produce organic acids such as lactic acid from various sugars and retain them in dental plaque, they invade tooth enamel and induce tooth decay. Next to streptococcus, which is a gingival marginal bacterium, is the gram-positive gonococcus centered on actinomyces. Actinomyces viscosus (Actinomyces viscosus) is a constituent bacteria of dental plaque and is also involved in calculus formation, and is detected in a high proportion from root caries, especially deep dentin caries lesions. In addition, it is considered that Actinomyces viscosus cell wall components mainly cause immunopathological injury and are involved in human gingival margin. Therefore, in order to prevent the occurrence of caries and calculus, the most effective method is to suppress the growth of the above-mentioned mutans streptococci and Actinomyces viscosus.

Periodontal disease causes halitosis (bad odor) and swelling / pain of the gingiva, and when further worsened, causes periodontal ligament disease, gingival pockets and alveolar bone loss, and tooth agitation / loss. Periodontal disease occurs when dental plaque or tartar is left untreated. Percentage of obligate anaerobes such as Fusobacterium nucleatum and Porphyromonas gingivalis that are known as pathogens of adult periodontitis in the plaque compared to the local bacterial flora of healthy gingiva Becomes higher. These bacteria are known to be causative bacteria that produce methyl mercaptan, which is a causative substance of bad breath. Therefore, in order to prevent the occurrence of periodontal disease and bad breath, it is the most effective method to suppress the growth of periodontal disease bacteria.

  Streptococcal infection is a diffuse inflammation of the dermis that develops when the inflammatory pathogenic Streptococcus pyogenes enters the pharynx and develops. It is an infant, elderly, or resistant It is a disease that is common in people who have declined. A fever, sore throat, tonsillitis, or a red rash caused by exotoxin produced by tongue and fungus is called scarlet fever.

  Staphylococci are the main pathogens of purulent diseases that are widely distributed in the nasal cavity, skin, oral cavity, digestive tract, and the like. A particularly highly pathogenic one is Staphylococcus aureus, which is a causative agent of food poisoning due to the intestinal toxin produced by the staphylococcus aureus. In the oral cavity, the rate of separation from infected root canals and root tip lesions with advanced caries is high. In addition, jawbone osteomyelitis, parotitis, etc. may occur.

  In recent years, it has been suggested that oral bacteria are associated with many systemic diseases such as pneumonia and cardiovascular diseases (see Non-Patent Document 1, for example). The need has been emphasized.

  Here, conventional treatments for the above oral diseases, streptococcal infections, and Staphylococcus aureus will be described below.

  As therapeutic agents for oral pathogenic bacteria such as caries and periodontal diseases, application of bactericides or antibacterial substances that suppress the growth of these pathogenic bacteria has been attempted. For example, bactericides such as chlorhexidine, cetylpyridinium chloride, and popidone iodine and antibacterial substances such as penicillins, cephems, new quinones, and macrolides have been used. (For example, see Non-Patent Documents 1 and 2) For hemolytic streptococci, antibacterial substances such as penicillin, erythromycin, and clindamycin are also used for treatment. Vancomycin is the most reliable antibacterial substance in Staphylococcus aureus, which has a problem with multidrug resistance such as methicillin and cephem resistance.

  However, although these antibiotics have a strong action, they have strong side effects, and it has been pointed out that resistant bacteria against these antibiotics may appear, making it difficult to use for a long time. Other antibacterials also have a fairly broad antibacterial spectrum, so using them at high concentrations can disrupt the normal bacterial flora in the oral cavity and cause fungal substitution, while using low concentrations can cause pathogenic bacteria. There was a problem that sufficient execution was not obtained. (For example, Non-Patent Documents 2 and 3)

  From such a point of view, various applications of relatively mild plant extracts and perfume ingredients have been studied as antibacterial substances that can be used on a daily basis. Green tea extract (catechins) (see, for example, Patent Documents 1 and 2 and Non-Patent Documents 4 and 5) as a product derived from foods or natural products and having an effect on oral diseases such as caries and periodontal disease. A thing, a car anterior extract (for example, refer patent document 3), a barley extract (for example, refer patent document 4), and a betel extract (for example, refer patent document 5) are known.

  However, since catechins derived from green tea are expensive, it has been difficult to add catechins in an effective amount to inhibit the growth of caries and periodontal diseases and to supply them at low cost. Also, since catechins have a peculiar unpleasant bitter taste and reduce human preference, supplying foods with excellent palatability by adding an effective amount of catechins that inhibit the growth of caries and periodontal fungi It was difficult.

  Furthermore, since catechins have high binding properties to proteins in foods, even if protein foods containing an effective amount of catechins are added to inhibit the growth of caries and periodontal disease bacteria, Further, there is a problem that it is difficult to cause catechins to remain and exert antibacterial activity. (For example, Non-Patent Document 6)

  On the other hand, those that have satisfactory activity have not been obtained, such as Seiko extract, car pea extract, pearl barley extract, betel extract and the like.
