TL;DR: It is reported that lipopolysaccharides of H. pylori express Lewis y, Lewis x, and H type I blood group structures similar to those commonly occurring in gastric mucosa, which indicates a direct pathogenic role for anti-Lewis antibodies in H. Pylori-associated type B gastritis.

TL;DR: In vitro-binding studies have demonstrated that LF binds directly to isolated lipid A and intact LPS of clinically relevant serotypes of the species which most frequently cause bacteremia, as well as to Lipid A and L PS of mucosal pathogens (among others, Neisseria meningitides and Haemophilus influenzae).

TL;DR: It was found that Bacteroides endodontalis, a newly described species of asaccharolytic black-pigmented Bactroides, was isolated almost exclusively from periapical abscesses of endodental origin.

TL;DR: It was concluded that mechanical periodontal treatment in combination with the metronidazole plus amoxicillin therapy is effective for subgingival suppression of A. actinomycetemcomitans in patients with severe periodontitis.

TL;DR: During pregnancy, more swelling, redness and bleeding on probing developed during experimental gingivitis than post-partum, whereas the amount of plaque was similar in both phases, which suggests that as a result of dental plaque accumulation, gingival inflammation develops superimposed on pregnancy-associated physiologic alterations.
