Effect of plasma-activated water on planktonic and biofilm cells of Vibrio parahaemolyticus strains isolated from cutting board surfaces in retail seafood markets. J Appl Microbiol 2024; 135:lxae182. [PMID: 39020257 DOI: 10.1093/jambio/lxae182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 07/04/2024] [Accepted: 07/16/2024] [Indexed: 07/19/2024]
Abstract
AIMS This research aimed to analyze cutting board surfaces in seafood markets to find Vibrio parahaemolyticus, assess the isolates' ability to form biofilms, generate and evaluate characteristics of plasma-activated water (PAW), and compare the effect of PAW on planktonic and biofilm cells of the isolated V. parahaemolyticus strains. METHODS AND RESULTS A total of 11 V. parahaemolyticus strains were isolated from 8.87% of the examined cutting boards. Biofilm-forming ability was evaluated for these isolates at temperatures of 10°C, 20°C, and 30°C using crystal violet staining. Four strains with the highest biofilm potential were selected for further analysis. The pH of the PAW used in the study was 3.41 ± 0.04, and the initial concentrations of hydrogen peroxide, nitrate, and nitrite were 108 ± 9.6, 742 ± 61, and 36.3 ± 2.9 µM, respectively. However, these concentrations decreased significantly within 3-4 days during storage at room temperature. PAW exhibited significant antimicrobial effects on V. parahaemolyticus planktonic cells, reducing viable bacteria up to 4.54 log CFU/ml within 20 min. PAW also reduced the number of biofilm cells on stainless steel (up to 3.55 log CFU/cm2) and high-density polyethylene (up to 3.06 log CFU/cm2) surfaces, although to a lesser extent than planktonic cells. CONCLUSIONS PAW exhibited significant antibacterial activity against V. parahaemolyticus cells, although its antibacterial properties diminished over time. Furthermore, the antibacterial activity of PAW against biofilm cells of V. parahaemolyticus was less pronounced compared to the planktonic cells. Therefore, the actual effectiveness of PAW in seafood processing environments can be affected by biofilms that may form on various surfaces such as cutting boards if they are not cleaned properly.

Insights from label free-based proteomic analysis into inhibitory effects ε-Poly-lysine against Vibrio parahaemolyticus. Microb Pathog 2021; 160:105169. [PMID: 34509528 DOI: 10.1016/j.micpath.2021.105169] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Revised: 08/28/2021] [Accepted: 08/29/2021] [Indexed: 11/23/2022]
Abstract
Vibrio parahaemolyticus is one of the most common pathogenic bacteria that pose a threat to human health. The purpose of this study was to investigate antibacterial mechanisms of ε-poly-lysine (ε-PL) against V. parahaemolyticus using a lable free-based proteomic analysis. The differentially expressed proteins (DEPs) were subjected to bioinformatics analysis. The results indicated that a total of 196 DEPs, including 118 up-regulated and 78 down-regulated, were identified in the ε-PL-treated cells compared with control group. Upon Go functional enrichment, 13, 9, and 8 specific Go terms in biological processes, molecular functions and cellular components were identified, respectively. KEGG pathways analysis indicated that the DEPs were mainly involved in bacterial chemotaxis, RNA transport and two-component system, which were significantly enriched (P < 0.05). In PPI analysis, Che R and Che V, both involved in bacterial chemotaxis and RNA transport pathways, are closely related to other DEPs. Therefore, the down-regulation of Che R and Che V in ε-PL-treated cells resulted in the reduction or even loss of bacterial adaptability, and they were the critical action sites of ε-PL to inactivate V. parahaemolyticus.

Abstract
The contamination of seafood with Vibrio species can have severe repercussions in the seafood industry. Vibrio species can form mature biofilms and persist on the surface of several seafoods such as crabs, oysters, mussels, and shrimp, for extended duration. Several conventional approaches have been employed to inhibit the growth of planktonic cells and prevent the formation of Vibrio biofilms. Since Vibrio biofilms are mostly resistant to these control measures, novel alternative methods need to be urgently developed. In this review, we propose environmentally friendly approaches to suppress Vibrio biofilm formation using a hypothesized mechanism of action.

Abstract
The objective of this study was to investigate the antibacterial and antibiofilm activity of eugenol against V. parahaemolyticus planktonic and biofilm cells and the involved mechanisms as well. Atime-kill assay, a biofilm formation assay on the surface of crab shells, an assay to determine the reduction of virulence using eugenol at different concentrations, energy-filtered transmission electron microscope (EF-TEM), field emission scanning electron microscopy (FE-SEM), confocal laser scanning microscope (CLSM) and high-performance liquid chromatography (HPLC) were performed to evaluate the antibacterial and antibiofilm activity of eugenol. The results indicated that different concentrations of eugenol (0.1-0.6%) significantly reduced biofilm formation, metabolic activities, and secretion of extracellular polysaccharide (EPS), with effective antibacterial effect. Eugenol at 0.4% effectively eradicated the biofilms formed by clinical and environmental V. parahaemolyticus on crab surface by more than 4.5 and 4 log CFU/cm2, respectively. At 0.6% concentration, the reduction rates of metabolic activities for ATCC27969 and NIFS29 were 79% and 68%, respectively. Whereas, the reduction rates of EPS for ATCC27969 and NIFS29 were 78% and 71%, respectively. On visual evaluation, significant results were observed for biofilm reduction, live/dead cell detection, and quorum sensing (QS). This study demonstrated that eugenol can be used to control V. parahaemolyticus biofilms and biofilm-related infections and can be employed for the protection of seafood.

Abstract
In this study, the effect of three essential oils (EOs) - clove oil (CO), thyme oil (TO), and garlic oil (GO), which are generally recognized as safe - on the planktonic growth, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), motility, biofilm formation, and quorum sensing (QS) of Vibrio parahaemolyticus was investigated. All three EOs showed bacteriostatic activity, with MICs in the range 0.02%-0.09% (v/v). CO and TO completely controlled planktonic growth at 0.28% and 0.08% (v/v), which is four times their MIC (4 × MIC), after 10 min, whereas GO completely controlled growth at 0.36% (v/v) (4 × MIC) after treatment for 20 min. V. parahaemolyticus motility was significantly reduced by all three EOs at 4 × MIC (0.28% for CO, 0.08% for TO, and 0.36% for GO), whereas QS was controlled and biofilm formation reduced by all three EOs at 8 × MIC (0.56% for CO, 0.16% for TO, and 0.72% for GO) after 30 min of treatment. These results suggest that CO, TO, and GO have a significant inhibitory effect on V. parahaemolyticus cells in biofilm sand thus represent a promising strategy for improving food safety. These results provide the evidence required to encourage further research into the practical use of the proposed EOs in food preparation processes.

Liao C, Zhao Y, Wang L. Establishment and Validation of RNA-Based Predictive Models for Understanding Survival of Vibrio parahaemolyticus in Oysters Stored at Low Temperatures. Appl Environ Microbiol 2017; 83:e02765-16. [PMID: 28087532 PMCID: PMC5335536 DOI: 10.1128/aem.02765-16] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 01/04/2017] [Indexed: 12/22/2022] Open
Abstract
This study developed RNA-based predictive models describing the survival of Vibrio parahaemolyticus in Eastern oysters (Crassostrea virginica) during storage at 0, 4, and 10°C. Postharvested oysters were inoculated with a cocktail of five V. parahaemolyticus strains and were then stored at 0, 4, and 10°C for 21 or 11 days. A real-time reverse transcription-PCR (RT-PCR) assay targeting expression of the tlh gene was used to evaluate the number of surviving V. parahaemolyticus cells, which was then used to establish primary molecular models (MMs). Before construction of the MMs, consistent expression levels of the tlh gene at 0, 4, and 10°C were confirmed, and this gene was used to monitor the survival of the total V. parahaemolyticus cells. In addition, the tdh and trh genes were used for monitoring the survival of virulent V. parahaemolyticus Traditional models (TMs) were built based on data collected using a plate counting method. From the MMs, V. parahaemolyticus populations had decreased 0.493, 0.362, and 0.238 log10 CFU/g by the end of storage at 0, 4, and 10°C, respectively. Rates of reduction of V. parahaemolyticus shown in the TMs were 2.109, 1.579, and 0.894 log10 CFU/g for storage at 0, 4, and 10°C, respectively. Bacterial inactivation rates (IRs) estimated with the TMs (-0.245, -0.152, and -0.121 log10 CFU/day, respectively) were higher than those estimated with the MMs (-0.134, -0.0887, and -0.0732 log10 CFU/day, respectively) for storage at 0, 4, and 10°C. Higher viable V. parahaemolyticus numbers were predicted using the MMs than using the TMs. On the basis of this study, RNA-based predictive MMs are the more accurate and reliable models and can prevent false-negative results compared to TMs.IMPORTANCE One important method for validating postharvest techniques and for monitoring the behavior of V. parahaemolyticus is to establish predictive models. Unfortunately, previous predictive models established based on plate counting methods or on DNA-based PCR can underestimate or overestimate the number of surviving cells. This study developed and validated RNA-based molecular predictive models to describe the survival of V. parahaemolyticus in oysters during low-temperature storage (0, 4, and 10°C). The RNA-based predictive models show the advantage of being able to count all of the culturable, nonculturable, and stressed cells. By using primers targeting the tlh gene and pathogenesis-associated genes (tdh and trh), real-time RT-PCR can evaluate the total surviving V. parahaemolyticus population as well as differentiate the pathogenic ones from the total population. Reliable and accurate predictive models are very important for conducting risk assessment and management of pathogens in food.

Abstract
Vibrio parahaemolyticus has been associated as the major cause of food poisoning and gastroenteritis in manycountries including Southeast Asia. Their human infection is regularly associated with the consumption of rawor undercooked seafood and contaminated water supplies. A rapid method of detection is important to monitorthe occurrence of V. parahaemolyticus in both food and environment samples especially in Malaysia. Thus, theaim of this study was to detect and enumerate V. parahaemolyticus from seafood by using the real-time PCRbased on the SYBR green assay. targeting the thermolabile (tl) gene. The assay was applied on 24 seafoodsamples comprised of 6 cockles, 6 prawns, 6 squids and 6 fishes. In this study, all of the six cockles and prawnswere positive for the presence of V. parahaemolyticus while fish samples have only 2 positive isolates.However, this study recorded no presence of V. parahaemolyticus in squids. Overall, the real-time PCR assaywas proven to be highly specific, and is sensitive in detecting and enumerating V. parahaemolyticus in theseafood samples. In addition, this study has proven that seafood (especially cockles and prawns) are potentialsources for V. parahaemolyticus.
