“…Our results showed that the capacity to form biofilms among the Y. enterocolitica examined strains could be a strain‐related feature. Although, some authors reported that all Y. enterocolitica strains examined in their studies had produced biofilms(Ioannidis et al 2014; Singhal et al 2019), our results are in accordance with other studies that showed differences in biofilm formation among the examined strains (Wang et al 2017; Zadernowska and Chajęcka‐Wierzchowska 2017; Younis et al 2019).…”

“…Although little has been published about the role of biofilms and the factors leading to biofilm formation in Y. enterocolitica , it has been well established that flagella play a critical role at the beginning of the biofilm formation (Liaqat et al 2018). Furthermore, Y. enterocolitica strains able to form biofilms have presented enhanced antibiotic resistance (Ioannidis et al 2014). Quorum sensing system in most of Gram‐negative bacteria is LuxI/LuxR‐type, corresponding to the acil‐homoserine lactones (AHL, a type of inductors) synthase and the response regulator (Shaaban et al, 2019).…”

Aims of the study The ability of Yersinia enterocolitica strains to form biofilms and the capacity of different alkaloids to inhibit biofilm formation were investigated. Methods and Results The capacity to form biofilm on polystyrene of 31 Y. enterocolitica strains was evaluated. Biofilm and quorum sensing (QS) inhibition of 17 alkaloids were assayed; furthermore, minimum biofilm inhibitory concentration (MBIC) was determined. The capacity to form biofilms among the examined strains seemed to be a strain‐related feature. The best biofilm inhibitors at 100 µmol l−1 were oliverine (1), guatterine (3), liriodenine (4), oliveridine (5) and pachypodanthine (6), which showed biofilm inhibition higher than 87%. Pachypodanthine (6) was the most effective compound with MBIC value of 12·5 µmol l−1 at subinhibitory concentration and also was able to inhibit QS system and reduce yenR expression at this concentration. Conclusion This is the first study to demonstrate that oliverine, liriodenine, and pachypodanthine are able to inhibit biofilm formation of Y. enterocolitica without critically disturbing its growing capacity. At MBIC, pachypodanthine inhibited biofilm formation and QS. Significance and Impact of the Study The use of aporphinoid alkaloids as biofilms inhibitory agents might potentially be useful to treat biofilm‐associated infections in the future.

“…The survival of Y. enterocolitica in the environment, including water environments, is also increased by the ability of Y. enterocolitica to form biofilms (Ioannidis et al 2014). The ability to form biofilms may allow microorganisms to persist in the environment and to resist desiccation and treatment with antimicrobial agents and disinfectants.…”

Major foodborne pathogens in fish and fish products: a review

Fish plays an important role in the human diet, and there is an observed increase in the consumption of fish per capita in Europe. However, intensive growth of industry and agriculture may cause contamination of natural and humanmade aquatic environments, and may affect not only the health of fish, but also raise safety concerns with regard to fish used for human consumption. It is well known that fish and fish products are often associated with human diseases. Thus, it is necessary to study the prevalence of pathogens in fish to ensure the safety of fish products and environments. Microbial assessment of fish also gives additional information about the hygienic status of environments, including lakes, rivers, ponds, and fish farms. Detection of pathogenic microorganisms or changes in natural microflora in the water environment could be an important indicator of possible contamination. The aim of this review was to describe and discuss the five most relevant bacterial genera and species linked to aquatic environments-Vibrio spp., Listeria monocytogenes, Yersinia spp., pathogenic Salmonella serovars, and Clostridium botulinum-causing human foodborne diseases.

Bacterial biofilms are communities of bacteria that form on surfaces and are extremely difficult to remove by conventional physical or chemical techniques, antibiotics or the human immune system. Despite advanced technologies, biofilm still contributes to 60 to 80% of human bacterial infections (NIH and CDC) and cause problems in many natural, environmental, bioindustrial or food processing settings. The discovery of novel substances that inhibit biofilm without increasing the virulence of the bacteria opens doors for countless applications where a reduction of biofilm is desired.
