The effects of pronase (PRN), cellulase (CEL) or DNaseI alone combined with benzalkonium chloride (BAC) against Listeria monocytogenes-carrying biofilms were assayed. best removal activity L. monocytogenes-Escherichia coli was obtained using followed by PRN and CEL. Subsequently, a modified logistic model used to quantify the BAC. A better BAC performance after compared eradicating monocytogenes observed. In E. opposite. Finally, DNaseI-BAC treatments two different biofilms. more effective...
The main aim of the present study was to evaluate level antibiotic resistance, prevalence and virulence features methicillin-resistant Staphylococcus aureus (MRSA) isolated from heavy swine at abattoir farming environments in Lombardy (Northern Italy). With this scope, 88 different farms were surveyed, obtaining a total n = 440 animal swabs 150 environmental swabs. A 87 MRSA isolates obtained, with an overall incidence 17.50% (n 77) among samples 6.67% 10) environmental. Molecular...
A harmonised microbiological survey was performed in two artisanal factories of raw goat milk cheeses (A and B) located the Andalusian region (Spain). total 165 different control points or samples (raw materials, final products, food-contact surfaces [FCS], air) were examined as microbial pathogen sources contamination cheeses. For analysed from both producers, concentrations aerobic-mesophilic bacteria (AMB), coliforms, coagulase-positive Staphylococcus spp. (CPS), lactic-acid (LAB) moulds...
This work presents the assessment of effectivity a pronase (PRN)-benzalkonium chloride (BAC) sequential treatment in removing Listeria monocytogenes–Escherichia coli dual-species biofilms grown on stainless steel (SS) using fluorescence microscopy and plate count assays. The effects PRN-BAC occupied area (OA) by undamaged cells 168 h samples were determined first-order factorial design. Empirical equations significantly (r2 = 0.927) described negative individual effect BAC interactive...
Furanones are analogues of acylated homoserine lactones with proven antifouling activity in both Gram-positive and Gram-negative bacteria though the interference various quorum sensing pathways. In an attempt to find new strategies prevent control Listeria monocytogenes biofilm formation on stainless steel (SS) surfaces, different concentrations six synthetic furanones were applied biofilms formed by strains isolated from food, environmental, clinical sources grown onto AISI 316 SS coupons....
Listeria monocytogenes is considered a foodborne pathogen of serious concern capable forming multispecies biofilms with other bacterial species, such as Pseudomonas spp., adhered onto stainless steel (SS) surfaces. In an attempt to link the biofilms’ morphology and resistance biocides, dual-species L. , in co-culture either aeruginosa fluorescens or putida were assayed ascertain their morphological characteristics toward benzalkonium chloride (BAC) neutral electrolyzed water (NEW)....
A study was conducted to evaluate the microbiological quality, safety, and variability along production chain of two artisanal salchichón factories in Andalusia. Aerobic mesophilic bacteria (AMB), total coliforms, coagulase-positive Staphylococcus spp. (CPS), lactic-acid bacteria, moulds yeasts presence bacterial pathogens were investigated 3 batches raw materials, finished products, food-contact surfaces (FCS) indoor ambient air by using classical PCR/PFGE techniques. Of 171 samples...

Listeria monocytogenes is a major foodborne pathogen which mainly infects susceptible individuals through the consumption of contaminated foods. To this end, ready-to-eat (RTE) food products are particular concern as microorganism widely distributed, can survive, and even grow, under adverse conditions, thus must be carefully controlled. In present study, an interlaboratory ring trial was organized to evaluate open formula qPCR-based method for detection L. monocytogenes. The molecular...
