| spontaneous bacterial peritonitis due to campylobacter coli. | a patient with alcoholic liver disease and ascites who developed fatal spontaneous bacterial peritonitis due to campylobacter coli is reported herein. this is the first case report of spontaneous bacterial peritonitis due to this organism. campylobacter infections and their relationship to spontaneous bacterial peritonitis are reviewed. | 1987 | 3569775 |
| demonstration of a flagellar antigen shared by a diverse group of spiral-shaped bacteria that colonize intestinal mucus. | western blot analysis showed that there is little immunological cross-reactivity of the human pathogens campylobacter jejuni and campylobacter coli with campylobacter pyloridis, except for a very strong cross-reaction between the flagellins. this same antigenic cross-reaction was found with two isolates of gram-negative spiral microaerophilic bacteria that are known to colonize the intestinal mucosa of rodents, but not with the flagellins of a number of other motile bacteria. it is proposed that ... | 1987 | 3818099 |
| erythromycin-resistant campylobacter infections in thailand. | erythromycin therapy was compared with no treatment in a prospective trial of acute diarrheal disease among 100 infants in an orphanage in bangkok. within 24 h of the onset of diarrhea, 50 children received erythromycin ethylsuccinate (40 mg/kg per day) in four divided doses for 5 days. campylobacter jejuni isolated from 31, campylobacter coli isolated from 21, and shigella spp. isolated from 21 of 100 children were the most commonly recognized pathogens; use of a sensitive, nonselective method ... | 1987 | 3579261 |

| typing of heat-stable and heat-labile antigens of campylobacter jejuni and campylobacter coli by coagglutination. | a coagglutination system has been devised for typing heat-stable and heat-labile antigens of campylobacter jejuni and c. coli. the use of protein a-positive staphylococcus aureus cells carrying campylobacter sp. serotype antibody and the treatment of campylobacter sp. cells with dnase in the antigen suspension permitted rapid and specific coagglutination of rough (autoagglutinable) as well as smooth cultures. cells of s. aureus were sensitized with campylobacter sp. serotype antisera. four to fi ... | 1985 | 3998098 |
| cadmium chloride susceptibility, a characteristic of campylobacter spp. | we report a simple diagnostic characteristic useful in the presumptive identification of campylobacter jejuni and campylobacter coli. filter paper disks impregnated with cadmium chloride were placed on streaked agar medium. zones of growth inhibition for campylobacter spp. occurred at 1.25 micrograms per disk. other enteropathogens (salmonella spp., shigella spp., vibrio cholerae, vibrio parahaemolyticus, escherichia coli, and yersinia enterocolitica) were resistant to at least 40 micrograms per ... | 1985 | 3998099 |
