Abstract EN
The present study was carried out to investigate the potential of Listeria ivanovii isolates to exist as biofilm structures.
The ability of Listeria ivanovii isolates to adhere to a surface was determined using a microtiter plate adherence assay whereas the role of cell surface properties in biofilm formation was assessed using the coaggregation and autoaggregation assays.
Seven reference bacterial strains were used for the coaggregation assay.
The degree of coaggregation and autoaggregation was determined.
The architecture of the biofilms was examined under SEM.
A total of 44 (88%) strains adhered to the wells of the microtiter plate while 6 (12%) did not adhere.
The coaggregation index ranged from 12 to 77% while the autoaggregation index varied from 11 to 55%.
The partner strains of S.
aureus, S.
pyogenes, P.
shigelloides, and S.
sonnei displayed coaggregation indices of 75% each, while S.
Typhimurium, A.
hydrophila, and P.
aeruginosa registered coaggregation indices of 67%, 58%, and 50%, respectively.
The ability of L.
ivanovii isolates to form single and multispecies biofilms at 25°C is of great concern to the food industry where these organisms may adhere to kitchen utensils and other environments leading to cross-contamination of food processed in these areas.
