1. Cinética do crescimento de Borrelia burgdorferi (Spirochaetaceae) em diferentes meios de cultivo
Estudou-se a cinética de crescimento de Borrelia burgdorferi, por um período de 3 meses, utilizando os seguintes oito meios de cultivo : (1) BSK adicionado de soro de coelho, (2) BSK adicionado de soro de suíno, (3) BSK adicionado de soro de suíno + 5 fluorouracil, (4) PMR, (5) CTB, (6) Dubos, (7) Caldo Brucella e (8) BHI. Todos os meios foram preparados

2. Antigenic cross-reactivity between Treponema pallidum and other pathogenic members of the family Spirochaetaceae.
The antigenic cross-reactivity between Treponema pallidum and several pathogenic members of the family Spirochaetaceae was examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting techniques. Blots of T. pallidum antigens were incubated with antiserum from rabbits infected or immunized with T. pallidum, Treponema paraluiscun

4. Phylogenetic position of the spirochetal genus Cristispira.
Comparative sequence analysis of 16S rRNA genes was used to determine the phylogenetic relationship of the genus Cristispira to other spirochetes. Since Cristispira organisms cannot presently be grown in vitro, 16S rRNA genes were amplified directly from bacterial DNA isolated from Cristispira cell-laden crystalline styles of the oyster Crassostrea virginica

5. Analysis of outer membrane ultrastructure of pathogenic Treponema and Borrelia species by freeze-fracture electron microscopy.
We analyzed the outer membrane (OM) ultrastructure of four pathogenic members of the family Spirochaetaceae by freeze fracture. The OM of Treponema pallidum subsp. pertenue contained a low intramembranous particle concentration, indicating that it contains few OM transmembrane proteins. The concave OM fracture faces of Treponema hyodysenteriae and Borrelia b

6. Utilization of Ammonia Nitrogen by Intestinal Bacteria Isolated from Pigs
In a medium containing ammonia, proteose peptone, and cysteine as nitrogen sources, 17 of 24 Bacteroidaceae strains, 3 of Selenomonas strains, 1 of 7 curved rods, 3 of 7 Spirochaetaceae strains, 8 of 20 Eubacterium strains, 8 of 13 Peptococcaceae strains, 3 of 4 Clostridium strains, 19 of 20 Enterobacteriaceae strains, and 1 of 8 Streptococcus strains utiliz
