comparison of campypak ii with standard 5% oxygen and candle jars for growth of campylobacter jejuni from human feces.to determine optimal temperature and atmospheric conditions for isolating campylobacter jejuni from fecal specimens of humans, we studied six laboratory isolates and 19 fecal specimens that were known to contain c. jejuni. we compared incubations in 5% oxygen, the campypak ii (bbl microbiology systems, cockeysville, md.) with 6 plates per jar (cp-6) and 12 plates per jar (cp-12), and candle jars at 37 and 42 degrees c. at both temperatures, the colony sizes for the laboratory strains were larger ...19826749892
factors affecting the lethality of campylobacter fetus subspecies jejuni in mice.intraperitoneal injection of campylobacter fetus ss. jejuni into ham/1cr mice was lethal, but viable counts of bacteria from whole body homogenates, organs and blood indicated that death was not due to sustained bacterial multiplication. heat-killed organisms (5 x 10(9) cfu) injected into 7-day-old mice caused death within 24 h and this was shown to be due to endotoxin. both ferric iron and heterologous lipopolysaccharide enhanced virulence; the ld50 was lowered from 1.8 x 10(9) cfu to 2.7 x 10( ...19846748038
systematic investigation of enrichment media for wild-type campylobacter jejuni strains.of the media examined, thioglycolate broth supplemented with 5% lysed sheep blood, butzler antibiotic mixture, and 0.1% lauryl sulfate was the most sensitive enrichment medium for recovery of wild-type strains of campylobacter jejuni from cecal contents of chickens and chicken livers. it allowed the retrieval of 1 cfu as did solid media but permitted the screening of 50-times larger volumes. double-strength enrichment medium required 5 to 10 cfu for growth. omission of lauryl sulfate reduced the ...19846746890
dna relatedness among strains of campylobacter jejuni and campylobacter coli with divergent serogroup and hippurate reactions.eleven strains of campylobacter from earlier fluorescent-antibody studies were examined by dna hybridization to determine their species. three of the strains hydrolyzed sodium hippurate, and eight did not. four of the hippurate-negative strains were in campylobacter jejuni serogroups, and the remaining strains were in both c. jejuni and campylobacter coli serogroups. dna relatedness to type strains of c. jejuni and c. coli indicated that all three of the hippurate-positive strains and two of the ...19846746886
properties of crude campylobacter jejuni heat-labile enterotoxin.the amount of crude campylobacter jejuni enterotoxin present in culture products was quantitated by comparing the response of these preparations with that of pure escherichia coli heat-labile toxin (lt) in the chinese hamster ovary assay and in enzyme-linked immunosorbent assays that used gm ganglioside or antisera to lt or both. maximum c. jejuni enterotoxin production was achieved by growth at 42 degrees c for 24 h under agitation in supplemented gc medium. adding polymyxin separately to eithe ...19846746090
