Evaluation of selected phenotypic features among Campylobacter sp. strains of animal origin

•Campylobacter strains exhibited differences in biofilm formation on polystyrene surface.•All tested Campylobacter strains possessed of the ability to colonize human Caco-2 cells.•The chosen phenotypic features had no correlation with biofilm formation by Campylobacter strains.

Description
Summary:•Campylobacter strains exhibited differences in biofilm formation on polystyrene surface.•All tested Campylobacter strains possessed of the ability to colonize human Caco-2 cells.•The chosen phenotypic features had no correlation with biofilm formation by Campylobacter strains. A total of 43 Campylobacter isolates from poultry, cattle and pigs were investigated for their ability to form biofilm. The studied strains were also screened for motility, adhesion and invasion of Caco-2 cells as well as extracellular DNase activity. The relation between biofilm formation and selected phenotypes was examined. Biofilm formation by the tested strains was found as irrespective from their motility and not associated with colonization abilities of human Caco-2 cells. Results of our study show that Campylobacter isolates from various animal sources are able to form biofilm and invade human Caco-2 cells in vitro.
