“…In case of Pseudomonas (PC2 Ps 3), the counts were 5.19±0.41 log 10 CFU/cm 2 after 3 h which to 7.965±0.174 log 10 CFU/cm 2 after 48 h incubation. These results are in accordance with the investigations of Chae and Schraft (2000), who experimentally proved that growth of L. monocytogenes in biofilm were independent of initial attachment. High biofilm formation potential on SS chips was observed for consortia after 3 h incubation as compared to individual strains, which showed almost two times higher log counts.…”

“…Some pathogenic bacteria are able to adhere to food-contact surfaces and remain viable even after cleaning and disinfection (Ammor et al, 2004). One of the most common ways for bacteria to live is adhering to surfaces and forming biofilms in which they are embedded in an organic, extracellular polymeric matrix (Chae, Schraft, 2000).…”

This study assessed the effect of different growth media [BHI broth, BHI broth plus glucose (10 g/100 mL) and BHI broth plus NaCl (5 g/100 mL)] and incubation temperatures (28 or 37 ºC) on the adherence, detachment and biofilm formation on polypropylene and stainless steel surfaces (2 x 2 cm coupons) for a prolonged period (24-72 h) by some strains of Staphylococcus aureus (S3, S28 and S54) from food processing plants. The efficacy of the sanitizers sodium hypochlorite (250 mg/mL) and peracetic acid (30 mg/mL) in reducing the number of viable bacterial cells in a preformed biofilm was also evaluated. S. aureus strains adhered in highest numbers in BHI broth, regardless of the type of surface or incubation temperature. Cell detachment from surfaces revealed high persistence over the incubation period. The number of cells needed for biofilm formation was noted in all experimental systems after 3 days. Peracetic acid and sodium hypochlorite were not efficient in completely removing the cells of S. aureus adhered onto polypropylene and stainless steel surfaces. From these results, the assayed strains revealed high capacities to adhere and form biofilms on polypropylene and stainless steel surfaces under the different growth conditions, and the cells in biofilm matrixes were resistant to total removal when exposed to the sanitizers sodium hypochlorite and peracetic acid.

Também foi avaliada a eficácia dos sanitizantes hipoclorito de sódio (250 mg/mL) e ácido peracético (30 mg/mL) na redução do número de células bacterianas viáveis presentes em um biofilme pré-formado. As cepas de S. aureus aderiram em número mais elevado quando incubadas em caldo BHI em ambos os tipos de superfícies e temperaturas de incubação testadas. A separação das células das superfícies revelou alta persistência ao longo do período de incubação. Número de células necessário para a formação do biofilme foi detectado depois de três dias de incubação em todos os sistemas experimentais. O ácido peracético e o hipoclorito de sódio não foram eficientes em remover completamente a células de S. aureus aderidas sobre as superfícies de polipropileno e aço inoxidável. Os resultados obtidos revelaram alta capacidade das cepas ensaiadas em aderir e formar biofilme sobre superfícies de polipropileno e aço inoxidável sobre diferentes condições de crescimento e que as células na matriz do biofilme apresentaram-se resistentes à total remoção quando expostas aos sanitizantes hipoclorito de sód...

“…monocytogenes is currently an understudied organism, considering its importance to human health and the goal of the food industry to limit its entry into human consumables. Abiotic surfaces on which L. monocytogenes grows as an attached community include borosilicate glass, stainless steel, rubber, and various plastics (3,4,14). Biotic surfaces of food materials known to sustain L. monocytogenes biofilms include those of plant and animal origin (7).…”

Loss of Flagellum-Based Motility by Listeria monocytogenes Results in Formation of Hyperbiofilms

Biofilm formation by the gram-positive, motile, food-borne pathogen Listeria monocytogenes was demonstrated to occur by an ordered series of stages. Biofilm development involves flagellum-based motility, which when blocked decreases initial bacterial surface attachment but subsequently leads to the formation of hyperbiofilms, surface-attached communities reaching high density.Listeria monocytogenes has emerged as a major foodborne pathogen posing a major public health concern because listeriosis has a fatality rate of 25% (13). Therefore, efforts to limit human exposure to L. monocytogenes that focus on defining mechanisms affecting its entry into the food supply have substantial public health value. The survival of L. monocytogenes in the food processing environment is prolonged because of its ability to establish biofilms on the surfaces of equipment. This is postulated to be a major reservoir contributing to food contamination and disease transmission (6,19
