Název v původním jazyce

The biofilm-positive Staphylococcus epidermidis isolates in raw materials, foodstuffs and on contact surfaces in processing plants

Popis výsledku v původním jazyce

Isolates from "farm to fork" samples (182 isolates from 2779 samples) were examined genotypically (icaAB geny) and phenotypically (in vitro biofilm formation, typical growth on Congo red agar; CRA) with the aim to assess the risk of penetration of virulent strains of Staphylococcus epidermidis into the food chain. The contamination of meat and milk products with S. epidermidis was significantly higher in comparison with raw materials. Contamination of contact surfaces in the meat processing plants was significantly lower than of contact surfaces in the dairy plants. The ica genes, which precondition the biofilm formation, were concurrently detected in 20 isolates that also showed a typical growth on CRA. Two ica operon-negative isolates produced biofilm in vitro, however, perhaps by an ica-independent mechanism. The surfaces in the dairy plants and the milk products were more frequently contaminated with ica operon-positive strains (2.3 and 1.2 % samples) than the other sample types (0
