They're part of the body's first line of defense against bacterial invasion.

And then a dressing of honey, to prevent any further bacterial invasions.

Black edges form when the highly vulnerable exposed areas suffer bacterial invasion.

In addition to bacterial invasion, enamel is also susceptible to other destructive forces.

The symptoms are a result of toxins or bacterial invasion into the intestine.

The darkening of vascular tissues following bacterial invasion gives the black rot disease its name.

Landaluce, though, steadily weakened from the blood clots formed by a severe bacterial invasion.

At various times following bacterial invasion, osteoblasts were lysed and total osteoblast protein isolated for further analysis.

Then, the hydroxylapatite crystals of enamel demineralize, allowing for greater bacterial invasion deeper into the tooth.

Dr. Stanley also showed that the bacterial invasion of teeth could destroy the cells and cause a loss of tooth vitality.

However, a highly efficient innate host defense system constantly monitors the bacterial colonization and prevents bacterial invasion of local tissues.

Another cause of sinus infections is a result of bacterial invasion within one or more of the sinus cavities.

In vivo, intra pair comparisons of bacterial invasion into dentinal tubules beneath ground, fractured and acid treated surfaces were made.

Protection from mechanical injury, chemical hazards, and bacterial invasion is provided by the skin because the epidermis is relatively thick and covered with keratin.

CNF1 alters host cell actin cytoskeleton and promotes bacterial invasion of the blood-brain barrier endothelial cells.

Also, if a diver touches a manta, it may scrape off the layer of mucus, which, Mr. Wing says, may subject the manta to bacterial invasion.

At the time when he became a professor, his reputation probably depended largely on his studies of the capillary circulation and of the blood cells concerned with defence against bacterial invasion.

It dampens the inflammatory response during bacterial invasion by suppressing the TNF-α-Receptor-associated factor 6 (TRAF6)-mediated signalling pathway.

He and other experts believe that a combination of genetic and environmental factors account for the greater susceptibility of nonwhite American children to the more severe form of this bacterial invasion.

The fact is that the body's ability to distinguish between its own cells and those of some foreign tissuea skin graft, say, or a bacterial invasion of the bloodisn't an inherited ability.

K. kingae infections are generally comcomitant with upper respiratory diseases or stomatitis, since disrupted respiratory or buccal mucosa is likely to facilitate bacterial invasion and hematogenous dissemination.

Saprolegnia is not a primary disease, but almost invariably the result of the spores invading an already damaged site - a wound or abrasion (which, incidentally, is prone to bacterial invasion, too, unless properly treated).

With the three toxin components deciphered, biologists are beginning to understand the extraordinary cunning with which the anthrax bacterium first stifles the body's immune system by blocking the signals that coordinate its usual defense against bacterial invasion.

The messenger, known as cyclic AMP, quickly reaches abnormally high levels, which derange the macrophages and block them from performing their usual role of sending out cytokines to alert the immune system to a bacterial invasion.

And people with certain heart problems or artificial joints are thought to be especially vulnerable to such bacteria, and are advised to take antibiotics whenever they have dental work that might cause bleeding, which opens the bloodstream to bacterial invasion.
