ACUTE ULCERATIVE GINGIVITIS

Pathogen-related spirochetes identified within gingival tissue from patients with acute necrotizing ulcerative gingivitis.

The purpose of this investigation was to determine whether monoclonal antibodies against pathogen-restricted antigens of Treponema pallidum subsp. pallidum could be used as probes for spirochetes in diseased gingival tissue from subjects with acute necrotizing ulcerative gingivitis. A biotin-streptavidin system was used to identify spirochetes bound by monoclonal antibodies in cryostat sections...

The epidemiology, etiology, and pathophysiology of acute necrotizing ulcerative gingivitis associated with malnutrition.

Acute Necrotizing Ulcerative Gingitivitis (ANUG) is a distinct and specific disease. This disease entity has been described as far back as the days of Hippocrates and is known by many synonyms. With the advent of antibiotics and with improved nutritional status, the incidence has decreased and even become extinct in developed countries. However, with the increasing incidence of severe immunodef...

Unexpected Acute Necrotizing Ulcerative Gingivitis in a Well-controlled HIV-infected Case

We herein report the case of a 41-year-old Japanese man with well-controlled HIV who presented with diagnostically difficult acute necrotizing ulcerative gingivitis (ANUG). After diet-induced weight loss, he developed oral pain and disturbance of mouth opening, and was admitted to our hospital. Based on preconceptions of HIV-associated diseases, fluconazole was initiated for candidiasis. Howeve...

Treponema putidum sp. nov., a medium-sized proteolytic spirochaete isolated from lesions of human periodontitis and acute necrotizing ulcerative gingivitis.

So far, little phenotypic heterogeneity has been detected in cultured oral treponemes with trypsin-like proteolytic activity, and all have been assigned to the species Treponema denticola. However, comparisons of protein patterns and antigen expression in our collection of proteolytic oral treponemes occasionally identified isolates with a unique phenotype; e.g. strain OMZ 830 (=ATCC 700768), w...
