Oral Microbiology

2. A Lactobacillus associated with dental caries
4. Some oral bacteria can reduce this dietary molecule from vegetables which eventually becomes an important signalling molecule
10. A small chemical signaling molecule used for communication between microorganisms
13. An early coloniser of plaque, can use lactate as an energy source
14. An bacterial enzyme that produces glucans
15. Mythical, Wept before Shamash and begged to live on the teeth and gums
18. A Fusobacterium which may play an important role in the ecological succession in dental plaque
19. The main acid produced by saccharolytic oral bacteria in times of sugar excess
20. Formed in the first stage of dental plaque formation
23. Part of the ranking system applied to all living things, sitting above species
24. A Streptococcus associated with infective endocarditis
25. Produced by some oral bacteria to store excess sugar from their environment
27. A relationship where one organism benefits and the other neither benefits or is harmed
29. A community of matrix-embedded microbial cells adhering to each other and a surface

1. The ability to survive and grow under low pH conditions
3. A group of species associated with the clinical signs of periodontal disease
5. Part of the "red complex" with Treponema denticola and Tannerella forsythia
6. Modified Koch's postulates for determining the causative agents of dental plaque related diseases
7. The plaque hypothesis describing the importance of the dental plaque environment in health and disease
8. A Streptococcus well adapted to low pH
9. A constant source of nutrients for bacteria in the oral cavity
11. Specific cell-to-cell recognition between compatible, genetically distinct cell types
12. The collection of microorganisms inhabiting a human body
16. An obligatory relationship where both organisms need each other
17. A genus recently implicated as important in plaque development and structure
21. A component of the extracellular plaque matrix which may help stabilise early biofilms
22. A vital step in being able to colonise the oral cavity
26. A state of balance between the oral microbiota and the host
28. The study of interrelationships between organisms and their surroundings
