摘要: In this report, Listeria monocytogenes isolates were evaluated for their ability to form biofilms, adhesion/invasion of eukaryotic cells and differential expression internalin A (inl A) gene, which is related virulence potential. The presence bacteriocins lactic acid bacteria incubation at 5 °C the main factors that influenced biofilm formation by L. monocytogenes, in comparison with BHI (control). general, adhesion invasion Caco-2 significantly lower low pH (4.5), Oxgall 0.3 %. On other hand, two (INCQS 353 Reg 26c) showed higher rates when cultivated NaCl 5 % (P < 0.05). One isolate (H-2) strongest invade cells, under selected conditions, suggesting there a relationship between For all isolates, inl gene was down-regulated bacteriocins, 0.3 %, 4.5 5 °C. Nonetheless, one (HU 471), eight times sucrose, indicating food components can increase infectiveness monocytogenes.
