Hi and Hello, I'm currently researching on the effect of plant extract on attachment and biofilm formation of dental plaque-causing bacteria. There are a few questions which confusing sometimes. Hopefully I able to get a clearer explanation regarding this question:
1. Does antibacterial activity reflect the antiadherence properties of the bacteria
2. What is the main difference between the antibacterial and antiadherence
3. Let say if bacterial able to attach to the non-shedding surface but growth is inhibited by the plant extract, does this mean that the extract does not promote antiadhereance activity.
The point is to distinguish clearly the mechanism of action of the substance in question that affects the population of bacteria. Antibacterial substances include those which stop bacteria from replicating without killing them (bacteriostatic) and those which kill bacteria (bactericidal). In the case of dental plaque-causing bacteria, if a substance only prevents adherence of the bacteria (antiadherence) to surfaces in the mouth, then the bacteria will most likely be washed away by saliva, even if the substance is neither bacteriostatic nor bactericidal. uUse of the specific terminology can explain clearly the mechanism of action of the substance. Bacteriostatic, bactericidal, and antiadherence are terms that avoid confusion, whereas antibacterial could be interpreted in a variety of ways.
