Superficial antigens of Campylobacter (Vibrio) fetus: characterization of antiphagocytic component.
A glycoprotein responsible for the antiphagocytic properties of Campylobacter fetus has been identified by comparing cells of a wild-type strain with those of a mutant lacking this substance. The antiphagocytic component is demonstrable through electron microscopy as a discrete, negatively charged structure on the periphery of the cell. CLT is readily removed from the cell by mild extraction pr...
متن کاملPathogenesis of Campylobacter fetus Infections
We developed a mouse model to compare the virulence of Campylobacter fetus strains with (S-plus) and without (Sminus) surface array protein (S-protein) capsules. In adult HA/ICR mice pretreated with ferric chloride, the LDF0 for S-plus strain 84-32 was 43.3 times lower than its spontaneous S-minus mutant 84-54. Seven strains of inbred mice were no more susceptible than the outbred strain. In co...
متن کاملCampylobacter Fetus Meningitis in Adults
The zoonotic pathogen Campylobacter fetus is a rare cause of bacterial meningitis. Little is known about the clinical characteristics, predisposing factors and outcome of C fetus meningitis in adults. We report cases of C fetus meningitis in a nationwide cohort study of adult bacterial meningitis patients in the Netherlands and performed a review of the literature. Two patients with C fetus men...
متن کاملHippurate hydrolysis by Campylobacter fetus.
An additional method for differentiating between Campylobacter fetus subsp. jejuni and C. fetus subsp. intestinalis is reported. Strains of C. fetus subsp. jejuni (18/20) were shown to hydrolyze hippurate in the 2-h rapid test, whereas strains of C. fetus subsp. intestinalis did not.
متن کاملCharacterization of the biochemical properties of Campylobacter jejuni RNase III
Campylobacter jejuni is a foodborne bacterial pathogen, which is now considered as a leading cause of human bacterial gastroenteritis. The information regarding ribonucleases in C. jejuni is very scarce but there are hints that they can be instrumental in virulence mechanisms. Namely, PNPase (polynucleotide phosphorylase) was shown to allow survival of C. jejuni in refrigerated conditions, to f...
