Lactic Bacterium and Bacillus Sp. Biofilms Can Decrease the Viability of Salmonella Gallinarum, Salmonella Heidelberg, Campylobacter Jejuni and Methicillin Resistant Staphylococcus Aureus on Different Substrates

This study aimed to evaluate the efficacy of biofilms formed by lactic acid bacteria and Bacillus sp. (BLA) in preventing controlling formation wild and/or planktonic forms Salmonella Gallinarum (SG), Heidelberg (SH), methicillin-resistant Staphylococcus aureus (MRSA) on different surfaces. The SH SG viability was evaluated polystyrene plates, wood shavings, soil samples. Two protocols were developed examine use BLA a preventive control application. For analysis Campylobacter jejuni (CJ) used only preventively plate. Results showed that effective growth all matrices. effectiveness for MRSA lower than SH. efficiency CJ seems be related initial contamination. proves potential alternative food-borne pathogens commonly encountered animal production food industry.
