The paper urged that "future research should aim to determine the frequency of these agonistic events and their cost to beaver survival and reproductive success, to determine if this relationship is really a commensal
one or some integration of strong positive and negative effects".
Virulence scores of pneumonia isolates (5 [3-7]) were significantly higher than those of commensal
isolates (3 [1-5]; p<0.0001) but not different from those of the bacteremia isolates (4 [2-7]; p = 0.3).
Soluble fiber is not digestible in the upper bowel and is thereby provided to resident commensal
bacteria lower in the bowel.
Microbial growth of commensal
organisms was detected on 13/15 (86.66 %) brushes tested in this study majority being streptococci along with E.
epidermidis is a common commensal
bacterium of the skin, whereas Staphylococcus aureus is a human pathogen.
Interestingly, LTA from skin commensal
bacteria can also directly influence MC activation by promoting their antimicrobial activity against vaccinia virus by means of production of cathelicidin .
Escherichia coli isolates are phylogenetically distributed among geographically distinct human populations.
One key factor in determining whether a host can maintain healthy gut microbiota communities is the ability to maintain colonization resistance, the process by which the host's commensal
gut bacteria prevent pathogenic bacteria from colonizing or expanding in the GI tract (12).
acnes is a commensal
bacterium on healthy skin seems to muddy the picture, until one also recognizes that there are different strains of P.
In birds of prey, white storks (Ciconia ciconia), and some waterfowl (Anatidae, Pelecanidae) species, mycoplasmas occur commonly and seem to be apathogenic or commensal
and most likely belong to the physiologic microbial flora of the respiratory tract.
The study showed a difference in the commensal
bacterial flora of the migraine patients from the control population.
Salmonella live in the gastrointestinal tract of a food animal without making it sick.
