Prevalence and molecular characterization of Aeromonas spp. in ready-to-eat foods in Italy.

摘要: A survey was carried out in Italy to ascertain the prevalence of Aeromonas spp. ready-to-eat foods (vegetables, cheeses, meat products, and ice creams) level molecular heterogeneity isolates found by macrorestriction analysis genomic DNA with pulsed-field gel electrophoresis (PFGE). In total, 46 (14.4%) 320 food samples examined were positive for The highest percentages isolation discovered vegetables, particularly lettuce (45.0%), endive (40.0%), rucola (20.0%). Ricotta only cheese type analyzed that showed a high frequency (45.0%). Among salami raw ham (25.0% positive) and, lesser extent, baloney (5.0%) hydrophila most common isolate from animal origin, whereas caviae dominant species vegetables. No motile aeromonads cream samples. geneti...
