Nutritional requirements of Treponema denticola and Treponema vincentii
Treponema denticola and Treponema vincentii were grown in a medium supplemented with 0.4% (wt/vol) alpha globulin in place of whole serum. Other serum fractions did not support growth. The growth factors in alpha globulin were destroyed by trypsin and by lipase. Lipid extraction of alpha globulin …

Lipid catabolism in Treponema
Members of the genus, Treponema, require long-chain fatty acids for growth in vitro. Serum, added to culture medium, provides a source of long-chain fatty acids. These fatty acids, however, are esterified to triglycerides, phospholipids, and cholesterol. In this study, the major pathways of complex …

Treponema hyodysenteriae: growth and production of hemolysin
Treponema hyodysenteriae is the causative agent of swine dysentery, a mucohemorrhagic disease of the intestines. T. hyodysenteriae requires phospholipids and cholesterol (or cholestanol) for growth, and it produces a a-hemolysin (TH) which is induced (300 fold) by the addition of RNA core to …

Analysis of plasminogen binding to Treponema denticola, a key periopathogen
… spirochetes. An increase in the oral spirochete, Treponema denticola, is highly correlated with periodontal disease progression and severity. The ability of this periopathogen to thrive in the subgingival crevice is dependent on complement evasion mechanisms. Earlier analyses demonstrated that the …

Characterization of Hpk2-Rrp2, two-component regulatory system in Treponema denticola
Treponema denticola levels in the gingival crevice become elevated as periodontal disease develops. Oral treponemes may account for as much as 40% of the total bacterial population in the periodontal pocket. The stimuli that trigger enhanced growth of T. denticola and the mechanisms associated with …

Investigation of the Efficacy of Various Proteinase-Treated "Serpula (Treponema) Hyodysenteriae" Vaccines
The problem. Swine dysentery is a severe mucohemorrhagic diarrheal disease that primarily affects swine during the growing-finishing period. The etiological agent of swine dysentery is "Serpula hyodysenteriae", an anaerobic Gram-negative spirochete. Financial losses from swine dysentery are a …

Characterization and differentiation of a soluble lipopolysaccharide type antigen from Treponema hyodysenteriae.
Whole cells of T. hyodysenteriae serotypes 1-7, avirulent T. hyodysenteriae serotypes 1 and 2, and 5 strains of T. innocens were chemically extracted to selectively remove a lipopolysaccharide-like substance (LPSLS). The different LPSLS were analyzed electrophoretically, immunologically, and …

Prevalence of the related treponematoses syphilis and yaws and co-occurrence of pathogens causing similar skin lesions in Ghana
… in Ghana. The agents causing these diseases, two Treponema pallidum subspecies, are genetically similar, but they have always been studied independently. In this context, this study aimed to assess the prevalence of these treponematoses and determine the co-occurrence of pathogens causing similar …
