Abstract
Oysters and mussels are known vectors of foodborne pathogens because of their immobile and filter-feeding nature leading to the accumulation of biological particles in their tissues. Accumulated bacteria which comes from the culture environment and unsanitary handling can cause food poisoning if these shellfish are consumed raw or partially processed. This study determined the incidence of bacterial pathogen contamination along the different channels of the oyster and mussel supply chain through a time-distribution simulation analysis. First, the route of the fresh bivalve products from a local farm to its market was established through interviews. From the data gathered, a simulation experiment was conducted following the observed time-temperature conditions and the actual bulk packaging material used by the traders. The presence of target pathogens Escherichia coli, Salmonella spp., Vibrio parahaemolyticus, and Vibrio cholerae were detected using standard conventional culture techniques. Initial E. coli counts in both mussels and oysters were higher than the safety limit of 330 MPN in 100 g tissue. Interestingly, E. coli counts in mussels decreased after 6 h and maintained low numbers after more than 24 h postharvest. Counts in oysters however increased to 1000 MPN in 100 g tissue. V. parahaemolyticus in mussels and oysters showed a gradual increase in counts with increasing holding time albeit in numbers that are lower than the safety limit of 1000 cfu g-1 tissue. Qualitative detection of Salmonella and V. cholerae showed the presence of both pathogens in all the sampling points. All four pathogens were also detected in the culture waters and in the sediment. Results of the study showed that the culture environment and the handling practices contribute greatly to the pathogen contamination in oysters and mussels.

Duplex On-Site Detection of Vibrio cholerae and Vibrio vulnificus by Recombinase Polymerase Amplification and Three-Segment Lateral Flow Strips. BIOSENSORS-BASEL 2021; 11:bios11050151. [PMID: 34066017 PMCID: PMC8151630 DOI: 10.3390/bios11050151] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 05/07/2021] [Accepted: 05/10/2021] [Indexed: 01/16/2023]
Abstract
Vibrio cholerae and Vibrio vulnificus are two most reported foodborne Vibrio pathogens related to seafood. Due to global ocean warming and an increase in seafood consumption worldwide, foodborne illnesses related to infection of these two bacteria are growing, leading to food safety issues and economic consequences. Molecular detection methods targeting species-specific genes are effective tools in the fight against bacterial infections for food safety. In this study, a duplex detection biosensor based on isothermal recombinase polymerase amplification (RPA) and a three-segment lateral flow strip (LFS) has been established. The biosensor used lolB gene of Vibrio cholerae and empV gene of Vibrio vulnificus as the detection markers based on previous reports. A duplex RPA reaction for both targets were constructed, and two chemical labels, FITC and DIG, of the amplification products were carefully tested for effective and accurate visualization on the strip. The biosensor demonstrated good specificity and achieved a sensitivity of 101 copies per reaction or one colony forming unit (CFU)/10 g of spiked food for both bacteria. Validation with clinical samples showed results consistent with that of real-time polymerase chain reaction. The detection process was simple and fast with a 30-min reaction at 37 °C and visualization on the strip within 5 min. With little dependence on laboratory settings, this biosensor was suitable for on-site detection, and the duplex system enabled simultaneous detection of the two important foodborne bacteria. Moreover, the principle can be extended to healthcare and food safety applications for other pathogens.

Abstract
Strains of diarrheagenic Escherichia coli (DEC) are involved in foodborne disease outbreaks worldwide, especially the enterohemorrhagic E. coli O157:H7. This study describes two multiplex quantitative real time PCR (qPCR) assays for simultaneous identification and quantification of genes related to virulence of DEC; a triplex reaction for detection and quantification of stxA1, stxA2, and eaeA genes, and a duplex reaction for detection and quantification of eaeA and virA genes. The technique was applied in raw oyster samples for direct quantification of DEC, thereby evaluating the applicability of this methodology for microbiological quality assessment of food. Using custom designed primers and specific MGB probes, a triplex qPCR assay was performed to quantify stxA1, stxA2, and eaeA, and a duplex reaction was performed to quantify virA and eaeA genes. The assays showed high sensitivity, with the detection limit varying between 5 and 17 copies of the genes. The coefficient of determination (R2) of the standard curves was 0.99. The coefficient of variation was < 1% indicated high intra- and inter-assay reproducibilities. The application of this methodology in oyster samples from tropical environment provided direct quantitative data that determined the presence of the genes stxA1 (32.1%), eaeA (28.6%), stxA2 (3.6%), and virA (3.6%). This would prove critical for immediate intervention of control strategies, particularly in oysters that are often ingested as raw food.

Abstract
The aim of this review is to present the methodologies currently applied to identify microbiota and pathogens transmitted to humans through seafood consumption, focusing on molecular techniques and pointing out their importance, advantages, disadvantages and applicability. Knowledge of available techniques allows researchers to identify which technique best fits their expectations. With such discernment, it will be possible to infer which disadvantages will be present and, therefore, not interfering with the final result. Two methodologies can be employed for this purpose, dependent and independent cultures. However, the dependent culture has certain limitations that can be solved through the independent cultivation techniques, such as PCR, PFGE and NGS, especially through the sequencing of the 16S rRNA region, providing a complete view of microbial diversity. These have revolutionized microbiological knowledge, mainly because they allow for the identification of uncultivable micro-organisms, which represent a substantial portion of total micro-organisms, making it possible to elucidate not yet described taxa which may display pathogenic potential, besides quantifying microbial communities, microbiota genetics, translated proteins and produced metabolites. In addition, transcriptomic and metabolomic techniques also allow for the evaluation of possible impacts that microbial communities may create in their environment, as well as the determination of potential pathogenicity to humans.
