| anaerobes in human biliary tracts. | during a 2-year period, 1,892 patients underwent biliary tract surgery at the mayo clinic. both aerobic and anaerobic cultures of bile were performed in 371 of these patients. sixty-nine percent of the cultures were positive, and 41% (117) of these grew anaerobes, although they were present in pure culture only twice. mixed cultures most commonly contained four different organisms (three aerobes and one anaerobe). bacteroides fragilis was the single most commonly isolated anaerobe and ranked fou ... | 1977 | 200634 |
| juvenile periodontitis (periodontosis). | juvenile periodontitis, characterized by early age of onset, rapid rate of periodontal tissue destruction and selective tooth involvement in the absence of commensurate aetiological factors, is recognized as a distinct clinical entity. the present paper describes the clinical findings and some immunological characteristics in a group of thirty-four patients under the age of thirty. clinical aspects studied included the influence of sex, race, family history and general health. immunological find ... | 1977 | 267621 |
| serological studies of bacteroides fragilis. | using direct agglutination methods, a simple serological scheme for the classification of bacteroides fragilis is described. twenty strains of b. fragilis were selected by a process of sucessive screening from 151 strains obtained from various sources. o-antigens were prepared from the 20 strains, and used to raise antisera in rabbits. each of the 20 antisera reacted with its homologous antigen and eight antisera cross-reacted with other subspecies. these cross-reactions were successfully remove ... | 1977 | 269199 |

| hemagglutinating activity of fusobacterium nucleatum. | gingival isolates of oral fusobacterium nucleatum strains (gram-negative anaerobic fusiform bacilli) have shown the characteristic ability to hemagglutinate a variety of erythrocytes (rbc) of human and animal origin. other members of the genus tested (f. necrophorus, f. varium, and f. mortiferum) displayed little if any ability to hemagglutinate rbc. the hemagglutination (ha) activity could be observed in the f. nucleatum strains with the whole cells and in most instances with sonicated preparat ... | 1977 | 401771 |
| evaluation of experimentally induced fusobacterium necrophorum infections in mice. | two strains of mice, swiss webster and dba/2cr, were injected intraperitoneally or intravenously with varying dosages of fusobacterium necrophorum. the ability to eliminate the infection was assessed by quantitative enumeration of the organisms present in the blood, liver, and spleen, three- to 4-week-old dba/2cr mice were highly resistant to both routes of injection. the intraperitoneal injection of older mice failed to demonstrate a dose-effect relationship whereas an intravenous injection of ... | 1977 | 403138 |
| [etiology of perioral dermatitis]. | the studies of röckl und schubert supported the theory that fusobacteria are often found in perioral dermatitis. when we characterize perioral dermatitis as fusobacteriosis, we do not have any doubt that fluorinated corticosteroids represent a very important pathogenetic factor. corticoids enable opportune fusobacteria to become pathogenic. in our opinion without these bacteria the beginning of the perioral dermatitis seems impossible. other supporting causes, which are relevant to sex distribut ... | 1977 | 403156 |
