| endotoxic activity and enterotoxigenicity of human strains of campylobacter jejuni isolated from patients in a nigerian hospital. | limulus gelation assay and dermal schwartzman reaction provided a sensitive and reproducible means of testing the endotoxic activity of hospital strains of campylobacter jejuni in lagos, nigeria. all the 22 isolates of campylobacter jejuni tested for the limulus gelation assay were positive for the production of endotoxin. furthermore, the campylobacter suspensions caused a positive dermal schwartzman reaction in rabbits. the area of skin reaction was less extensive than that produced by escheri ... | 1989 | 2632005 |
| natural bactericidal activity of human serum against strains of campylobacter jejuni isolated in lagos, nigeria. | the sensitivity of campylobacter jejuni strains la4, la12, la36, la53, la1214, la1308 and la1309 constituting the most prevalent strains of c. jejuni isolated in lagos, nigeria to the bactericidal activity of normal human serum was determined using microtiter technique. results obtained shows that only strains la 36 and la53 were serum resistant while others (strains la4, la12, la1214, la1308 and la1309) were serum sensitive. this finding is important epidemiologically and is the first report on ... | 1989 | 2805054 |
