Morphology and adhesion of Campylobacter jejuni to chicken skin under varying conditions.

Abstract:

:The adhesion of Campylobacter jejuni to chicken skin, along with the associated morphological changes under aerobic conditions at 4, 25, and 37 degrees C and microaerobic (O2 5%, CO2 10%, N2 85%) conditions, were investigated using confocal laser scanning microscopy (CLSM), flow cytometry, and plate counting. The morphological change of C. jejuni from a spiral shape to a coccoid form or VBNC form (viable but nonculturable form) progressed rapidly under aerobic conditions at 25, 37, and 4 degrees C. As regards adhesion, the C. jejuni cells were mostly located in the crevices and feather follicles of the chicken skin, where the cells in the feather follicles floated freely in the entrapped water, even after the skin was rinsed quite thoroughly. CLSM also revealed the penetration of some spiral-shaped C. jejuni cells into the chicken skin. Even after changing their shape at various temperatures, coccoid-form C. jejuni cells were still found in the crevices and feather follicles of the chicken skin.
