| 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 |

| characteristics of yersinia intermedia-like bacteria isolated from patients with diarrhea in nigeria. | five yersinia strains, biochemically mimicking yersinia intermedia, were isolated from patients with acute diarrheal diseases seen at the university of lagos (nigeria) teaching hospital between october 1979 and september 1982. the five isolates utilized citrate as their source of carbon and fermented sucrose, l-rhamnose, and alpha-methyl-d-glucoside, but unlike any other y. intermedia biogroup, they failed to ferment d-melibiose or d-raffinose. they all belonged to serogroup o:52,53. four autoag ... | 1986 | 3711276 |
| patterns and properties of haemagglutinins expressed by shigella serogroups in lagos, nigeria. | forty-five strains of shigella were screened for haemagglutinin production and broad-spectrum haemagglutination reaction. mannose-sensitive haemagglutinin (msha) was found in 22 strains [shigella flexneri (7), s. dysenteriae (7), s. sonnei (3), and s. boydii (5)]. eighteen strains harboured mannose-resistant haemagglutinin (mrha), and 8 strains were observed to be non-haemagglutinating to guinea pig erythrocyte. with the exception of human erythrocytes (o, a, b, and ab), the observed msha and mr ... | 2003 | 13677435 |
