Effect of high-fiber and high-oil diets on the fecal flora of swine Open
Six pairs of pigs were fed a basal diet, a high-fiber diet, and a diet high in corn oil in different sequences to minimize the carry-over effect of diet. After 2 months on each diet, a fecal specimen from each pig was cultured on nonselect…
Comparative bacteriology of juvenile periodontitis Open
Statistical comparisons of the floras associated with juvenile periodontitis, severe periodontitis, and moderate periodontitis indicated that differences in the bacterial compositions of affected sites in these populations were not statist…
Variation in periodontal floras Open
Statistical analyses indicated (i) that the floras of individual samples taken from the depth of sulci with nickel-plated Morse 00 scalers were highly reproducible and representative of the flora present at any given time, (ii) that the di…
Bacteriology of experimental gingivitis in children Open
Children are more resistant to gingivitis than are adults. To determine possible differences in their periodontal floras, an experimental gingivitis study, identical in design to one reported earlier with young adults, was conducted with f…
Bacteriology of moderate (chronic) periodontitis in mature adult humans Open
A total of 171 taxa was represented among 1,900 bacterial isolates from 60 samples of sites affected with moderate periodontitis in 22 mature adult humans. The composition of the subgingival sulcus flora was statistically significantly dif…
Electrophoretic study of Clostridium species Open
Polyacrylamide gel electrophoretic analysis of soluble cellular proteins (without sodium dodecyl sulfate) of 70 Clostridium species indicated that the procedure was readily applicable to the differentiation of species in the genus. The pro…
Polyacrylamide Slab Gel Electrophoresis of Soluble Proteins for Studies of Bacterial Floras Open
A polyacrylamide slab gel electrophoresis procedure was used to compare cellular proteins from bacterial isolates of gingival crevice floras. Isolates with identical protein patterns consistently were shown to be members of the same specie…
Clostridium limosum andre in Prevot 1948, 165 amended description and pathogenic characteristics Open
Seventeen strains of Clostridium limosum (Prévot) isolated from soil and fatal infections in cattle, swine, chickens, alligators, and from other sources are described. Strains of this species are proteolytic, nonsacc harolytic, slightly to…
Clostridium oroticum comb. nov. amended description Open
The organism formerly designated Zymobacterium oroticum, Wachsman and Barker (1954), has been shown to produce heat resistant spores, and is therefore a member of the genus Clostridium. The characteristics of C. oroticum differ significant…
VALIDITY OF <i>PROPIONIBACTERIUM ACNES</i> (GILCHRIST) DOUGLAS AND GUNTER COMB. NOV Open
