Demonstration of a cytotoxin from Campylobacter jejuni.
A 48-hour culture filtrate of Campylobacter jejuni was found to produce cytopathic effects on three human cell lines--that is, HeLa, MRC-5 and Hep-2. The cytopathic effects observed include cell rounding, loss of adherence and cell death after 24-48 h of incubation. Such morphological changes were observed with eight of the eleven strains of Campylobacter jejuni isolated from the blood/stools o...
متن کاملProduction of enterotoxin and cytotoxin in Campylobacter jejuni strains isolated in Costa Rica.
The production of toxins by 79 strains of Campylobacter jejuni isolated in Costa Rica from children with campylobacter-induced diarrhoea (44 strains) and from chickens (35 strains) was studied. An enterotoxic effect giving a rounding of mouse adrenocortical tumour (Y1) cells, which could be neutralised with antitoxin against Escherichia coli heat-labile enterotoxin, was detected in supernates f...
متن کاملUnique features of a highly pathogenic Campylobacter jejuni strain.
Campylobacter jejuni, a major human enteric pathogen, exhibits significant strain-to-strain differences which result in differences in pathogenic potential. C. jejuni 81-176 is a highly virulent strain that exhibits unique pathogenic features and is used by many research laboratories. We have determined the nucleotide sequence of its genome and compared it to the genomes of other sequenced C. j...
متن کاملInflammasome activation by Campylobacter jejuni.
The Gram-negative pathogen Campylobacter jejuni is the most common cause of bacterial foodborne disease worldwide. The mechanisms that lead to bacterial invasion of eukaryotic cells and massive intestinal inflammation are still unknown. In this study, we report that C. jejuni infection of mouse macrophages induces upregulation of pro-IL-1β transcript and secretion of IL-1β without eliciting cel...
متن کاملThe Role of Campylobacter Jejuni in Campylobacteriosis
Campylobacter jejuni is a Gram negative, curved, motile, thermophilic and microaerophilic bacillus in Campylobacteriaceae family, which is one of the main causes of enteritis in human named campylobacteriosis. The main reservoir of Campylobacter jejuni is the alimentary tract of animals, especially chicken and turkey. Consumption of semi-cooked chicken meat, raw milk and unchlorinated water are...
