“…1 It is well known that biofilm forming pathogens are responsible for severe infections which are generally very difficult to treat. 3 Recently the rise of biofilm infections have caused an increasing demand for the development of novel natural antimicrobials derived from plants used in ethnomedicine. 2 Therefore, biofilms present severe problems for food industry as well as for medical and healthcare industries.…”

Health beneficial properties of Rosa canina species are mainly attributed to rose hips, while the leaves are usually discarded as waste. In the present study we investigated chemical constituents as well as antimicrobial and antibiofilm potential of R. canina methanolic leaf extract. Chemical analysis showed that dominant phenolic compounds are quercetin and isorhamnetin derivatives (isoquercetin and isorhamnetin-3-O-rutinoside). Among the tested bacteria, Pseudomonas aeruginosa and Salmonella typhimurium were the most susceptible to the activity of R. canina leaf extract with MIC and MBC values both 0.009 mg mL −1 . For most of the bacterial strains investigated the extract showed significantly higher activity compared to the used standard compounds streptomycin and ampicillin. Also the tested extract powerfully inhibited in vitro biofilm growth in Pseudomonas aeruginosa, Staphylococcus aureus, Leishmania monocytogenes and Escherichia coli at sub MIC-levels. With concentrations equal to 1/4 and 1/8 of MIC values biofilm growth of P. aeruginosa and E. coli was inhibited by 90%. The obtained results are significant for a wider and efficient use of R. canina leaves.

“…In the first step, the microbe is reversibly attached to a surface through a weak interaction (such as the van der Waals forces) with an abiotic or biotic surface. In the second step, irreversible attachment is mediated by flagella, pili, and other surface appendages or particular receptors (Sadekuzzaman, Yang, Mizan, & Ha, ). The multilayered cells are accumulated by subdivision, then, they start production of their self‐produced extracellular polymeric substances (EPS) matrix, mainly composed of polysaccharides, proteins, and extracellular DNA, which facilitate the maturation of the biofilm (Elbarasi, ).…”

Biofilms are communities of microorganisms that are formed on and attached to living or nonliving surfaces and are surrounded by an extracellular polymeric material. Biofilm formation enjoys several advantages over the pathogens in the colonization process of medical devices and patients' organs. Unlike planktonic cells, biofilms have high intrinsic resistance to antibiotics and sanitizers, and overcoming them is a significant problematic challenge in the medical and food industries. There are no approved treatments to specifically target biofilms. Thus, it is required to study and present innovative and effective methods to combat a bacterial biofilm. In this review, several strategies have been discussed for combating bacterial biofilms to improve healthcare, food safety, and industrial process.

“…Sonication is well established as a method to clean surfaces and aid in the removal of biofilms from many types of material surfaces (17)(18)(19). Sonication can be applied to remove adhered biofilms while maintaining cell viability, if employed properly (14,20,21).…”

Listeria monocytogenes is of great concern in food processing facilities because it persists in biofilms, facilitating biotransfer. Stainless steel is commonly used for food contact surfaces and transport containers. L. monocytogenes biofilms on stainless steel served as a model system for surface sampling, to test the performance of a sonicating swab in comparison with a standard cotton swab. Swab performance and consistency were determined using total viable counts. Stainless steel coupons sampled with both types of swabs were examined using scanning electron microscopy, to visualize biofilms and surface structures (i.e., polishing grooves and scratches). Laser scanning confocal microscopy was used to image and to quantitate the biofilms remaining after sampling with each swab type. The total viable counts were significantly higher (P Յ 0.05) with the sonicating swab than with the standard swab in each trial. The sonicating swab was more consistent in cell recovery than was the standard swab, with coefficients of variation ranging from 8.9% to 12.3% and from 7.1% to 37.6%, respectively. Scanning electron microscopic imaging showed that biofilms remained in the polished grooves of the coupons sampled with the standard swab but were noticeably absent with the sonicating swab. Percent area measurements of biofilms remaining on the stainless steel coupons showed significantly (P Յ 0.05) less biofilm remaining when the sonicating swab was used (median, 1.1%), compared with the standard swab (median, 70.4%). The sonicating swab provided greater recovery of cells, with more consistency, than did the standard swab, and it is employs sonication, suction, and scrubbing.IMPORTANCE Inadequate surface sampling can result in foodborne illness outbreaks from biotransfer, since verification of sanitization protocols relies on surface sampling and recovery of microorganisms for detection and enumeration. Swabbing is a standard method for microbiological sampling of surfaces. Although swabbing offers portability and ease of use, there are limitations, such as high user variability and low recovery rates, which can be attributed to many different causes. This study demonstrates some benefits that a sonicating swab has over a standard swab for removal and collection of microbiological samples from a surface, to provide better verification of surface cleanliness and to help decrease the potential for biotransfer of pathogens into foods.KEYWORDS biofilm, capture, removal, sonicating, swab I n 2011 to 2014, the Centers for Disease Control and Prevention reported a total of 87 foodborne disease outbreaks in which cross contamination of ingredients was determined to be a contributing factor (1-4). Many of the reports likely involve cross
