What antibiotic kills Streptococcus mutans?

Penicillin is effective against strains of the gram-positive Streptococci and Staphylococci, as well as some gram-negative bacteria [29, 30]. The first use of penicillin to treat dental caries dated from 1946, when McClure and Hewitt reported that penicillin inhibited caries in rats [31].

What does Streptococcus mutans feed on?

Streptococcus mutans, which causes dental caries, splits the sucrose in food and uses one of the sugars to build its capsule, which sticks tightly to the tooth. The bacteria that are trapped in the capsule use the other sugar to fuel their metabolism and produce…

How do you get the bacteria Streptococcus mutans?

Life in the oral cavity Dental plaque adheres to the teeth and consists of bacterial cells, while plaque is the biofilm on the surfaces of the teeth. Dental plaque and S. mutans is frequently exposed to “toxic compounds” from oral healthcare products, food additives, and tobacco.

Which medicine is best for mouth infection?

Which medicine is best for mouth infection?

  • Amoxicillin (drug of choice for mouth infection)
  • Azithromycin.
  • Cefoxitin.
  • Metronidazole.
  • Penicillin.

What kills bacteria that causes tooth decay?

While all types of fluoride help to make tooth enamel stronger and resistant to acid attacks, stannous fluoride also kills bacteria that cause cavities and gingivitis.

How do you get rid of mutans streptococci?

As decay does not form without strep mutans, one approach to staying cavity-free is to reduce strep mutans levels. Antibacterial mouthwashes containing chlorhexidine gluconate have been shown to reduce the level of bacteria in the mouth, including lowering the levels of strep mutans, resulting in a lower decay rate.

What body system does Streptococcus mutans affect?

Oral streptococci, like Streptococcus mutans, are associated with pyogenic and other infections in various sites including mouth, heart, joints, skin, muscle, and central nervous system [4].

Who is most likely to get Streptococcus mutans?

The results showed that females (p = 0.006), children with enamel hypoplasia (p = 0.024), children with low birth weights (p = 0.005), those who consume more sweets (p < 0.001), and those with a higher proportion of visible plaque (p = 0.020 and p = 0.041) were more likely to be colonized by S. mutans.

What is the role of Spx proteins in Streptococcus mutans?

Two Spx proteins modulate stress tolerance, survival, and virulence in Streptococcus mutans. J Bacteriol192:2546–2556. [PMC free article][PubMed] [Google Scholar] 91. Stock AM, Robinson VL, Goudreau PN. 2000. Two-component signal transduction. Annu Rev Biochem69:183–215. [PubMed] [Google Scholar] 92. Smith EG, Spatafora GA. 2012.

What is Streptococcus mutans?

Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. It is part of the ” streptococci ” (plural, non-italic lowercase), an informal general name for all species in the genus Streptococcus.

What is the pathophysiology of Streptococcus mutansextracellular DNA upregulation?

Streptococcus mutansextracellular DNA is upregulated during growth in biofilms, actively released via membrane vesicles, and influenced by components of the protein secretion machinery. J Bacteriol196:2355–2366. [PMC free article][PubMed] [Google Scholar] 70.

Are Streptococcus mutans dominant in oral biofilms?

Streptococci represent 20% of the oral bacteria and actually determine the development of the biofilms. Although S. mutans can be antagonized by pioneer colonizers, once they become dominant in oral biofilms, dental caries can develop and thrive.
