adherence to host cell question
Posted 06 June 2012 - 04:04 AM
If a bacterium is covered by a capsule, and you have a possible adhesin embedded in the cell membrane, does the capsule not hinder the ability of the adhesin to adhere to the host cell?

If so, yes, a long as the capsule is there (around the bacterial cell) then the bacterium cant adhere to the host cell..
I am not sure this is what you mean and I also find it a bit strange for a question.
Are you thinking about probioticum capsules perhaps? or something like that?

The "adhesins" may also be polymeric molecules bound to the tips of the fimbriae (or any other cellular structures). So the presence of a capsule would not stop the bacterium from sticking.
See Figure 2 of this article: http://mmg.uth.tmc.e...llen_040312.pdf
Really, pito's probiotic capsules or the structural capsule?
