Abstract
Vulvar abscesses can progress to cause significant illness requiring disfiguring surgical debridement, broad spectrum antibiotics, and require hospitalization. A retrospective review of de-identified charts of 13 patients admitted for inpatient care for vulvar abscesses from 2004-2009 at West Virgini...

Abstract
This study aimed to assess the prevalence of seven periodontal marker pathogens, before implant placement and 1 yr after loading, in periodontally healthy individuals and to assess the long-term effectiveness of pre-implant reduction of pathogens to below threshold levels. In 93 individuals needing...

Abstract
More species were detected in patients with disease (GR or RP) than in those without disease (PH). Subjects with RP were distinguished from GRs or those with PH by a significantly higher frequency of putative periodontal pathogens, such as Parvimonas micra (previously Peptostreptococcus micros or Mi...

Abstract
SMAP28, thought to be the biologically active peptide, was the most potent antimicrobial (range of minimum inhibitory concentrations 0.06-7.03 microg/ml, P < 0.05); however, the activity of SMAP28 and SMAP29 was strongly associated (r = 0.933). The congeners also demonstrated antimicrobial activity...

We studied the effect of temperature and of urea on peptostreptococcal Protein L destructuration. We performed standard molecular dynamics simulations at 300 K, 350 K, 400 K, and 480 K, both in 10 M urea and in water. Protein L followed at least two alternative unfolding pathways. Urea caused the lo...
