“…In other enteric bacteria, Fur is a known regulator of acid shock proteins (ASPs), which protect and repair the damages that occur in cellular components following acid exposure (12,45,46). Therefore, it is tempting to speculate that the acid survival defect of the C. jejuni ⌬fur mutant results from the absence of ASP expression.…”

“…significantly affect the ability of C. jejuni to kill wax worms. The role of Fur in flagellar gene regulation and the importance of flagella for C. jejuni pathogenesis (42,45) could account for the virulence defect of the ⌬fur mutant in the G. mellonella larvae relative to the virulence of the wild-type strain. From all the information mentioned above, it is clear that Fur plays a critical role in C. jejuni host pathogenesis.…”

“…Bacterial cultures were resuspended in MH broth to an OD 600 of ϳ0.5, and a metal wire was dipped into each culture and stabbed into a plate of MH broth with 0.4% agar. Each plate contained a positive control (NCTC11168) and a nonmotile negative control (NCTC11168 ⌬flgK) (12), to account for plate-to-plate variation. After a 48-h incubation, the diameters of growth for each sample were measured and compared to that for NCTC11168 with paired t tests.…”

“…Bacteria from cultures grown overnight on MHϩTrM plates were resuspended in phosphate-buffered saline (PBS) to an OD 600 of 1.0, and 1.5 ml was aliquoted into 2.0-ml centrifuge tubes in triplicate. The C. jejuni NCTC11168 ⌬flgK strain has almost entirely absent flagella (12) and was therefore used as a likely negative control (47). Bacterial suspensions were incubated for 24 h at room temperature, followed by the removal of 200 l from the top of the sample for OD 600 measurements.…”

“…Although no specific point mutation was observed in the 23S rRNA gene of J.L.270, this Ery r strain carried a mutation in the ribosomal protein L4 (G74D). Since motility is a key factor influencing the ability of Campylobacter to colonize the chicken intestinal tract (18,23,28,39), the motility of Ery r and Ery s Campylobacter strains used in the present study was investigated. The Ery r and Ery s strains were equally motile under the laboratory conditions used here (data not shown).…”
