Oral bacterial flora and oral cancer: The possible link?

Defining the normal bacterial flora of the oral cavity.

More than 700 bacterial species or phylotypes, of which over 50% have not been cultivated, have been detected in the oral cavity. Our purposes were (i) to utilize culture-independent molecular techniques to extend our knowledge on the breadth of bacterial diversity in the healthy human oral cavity, including not-yet-cultivated bacteria species, and (ii) to determine the site and subject specifi...

Normal oral bacterial flora from some southern African snakes.

Effect of chitosan oral consumption on intestinal bacterial flora of rainbow trout (Oncorhynchus mykiss)

Rainbow trout is one of the most important breeding species in the world. The use of growth promoters, immune stimulants and prebiotics can improve the breeding efficiency of this fish. This study seeks to determine the prebiotic effects of chitosan in salmon. For this purpose, chitosan (1%, 0.5% and 0.25%) was added to the diet of rainbow trout with an average weight of 180g.
