Abstract
The intensive labour and time required for conventional methods to identify bacterial fish pathogens have revealed the need to develop alternative methods. Raman spectroscopy has been used in the rapid optical identification of bacterial pathogens in recent years as an alternative method in microbiology. Strains of bacterial fish pathogens (Vibrio anguillarum, Lactococcus garvieae and Yersinia ruckeri) that often cause infectious diseases in fish were here identified and analyzed in terms of their biochemical structures in different media and at different incubation times, and the data were specified by using Raman spectroscopy. The results demonstrated that Raman spectroscopy presents species-specific Raman spectra of each disease-causing bacteria and that it would be more appropriate to choose general microbiological media over selective media for routine studies. Additionally, it was found that species-specific band regions did not differ in 24- and 48-hour cultures, but there could be a difference in peak intensity which may lead to difficult characterization of spectrum. The current study, conducted for the first time with bacterial fish pathogens under different incubation conditions, is believed to provide a basis for the routine use of Raman spectroscopy for quick pathogen identification and the precise determination of the methodology for further research.

Rapid capture and quantification of food-borne spores based on the double-enhanced Fe 3O 4@PEI@Ag@PEI core-shell structure SERS sensor. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2024; 305:123512. [PMID: 37864975 DOI: 10.1016/j.saa.2023.123512] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 09/21/2023] [Accepted: 10/08/2023] [Indexed: 10/23/2023]
Abstract
To realize rapid capture and quantification of food-borne spores and prevent their potential harm, Fe3O4@PEI@Ag@PEI core-shell structure nanoparticles were combined with flower-like AgNPs for double enhancement and efficient capture of spores. The developed sensor showed excellent reproducibility and SERS enhancement factor (AEF) is 4.6 × 104. Orthogonal partial least-squares discrimination analysis and linear discriminant analysis accurately identified the three spores (Bacillus subtilis, Bacillus cereus, and Clostridium perfringens), and the qualitative identification accuracy of linear discriminant analysis was 100 %. Efficient enrichment of B. subtilis spores was realized within 5 min, with a detection limit of 3 cfu/mL. Spiked tests revealed that this sensor was effective in detecting spores in milk, orange juice, and water samples, with recovery ratio of 95.2-103.9 % and relative standard deviation of 3.1-7.7 %. Thus, the developed sensor was accurate and reliable, and could achieve rapid identification and quantitative detection of food-borne spores.

Int J Food Microbiol 2023; 396:110200. [PMID: 37119648 DOI: 10.1016/j.ijfoodmicro.2023.110200] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 03/15/2023] [Accepted: 04/01/2023] [Indexed: 05/01/2023]
Abstract
Clostridium perfringens can form metabolically dormant spores that can survive in meat preservation processes and cause food spoilage and human disease upon germination and outgrowth. The characteristics of spores in food products are closely related to the sporulation environment. To control or inactivate C. perfringens spores in food industry, the effects of sporulation conditions on the spores characteristics should be examined. This study aimed to investigate the effects of temperature (T), pH, and water activity (aw) on the growth, germination, and wet-heat resistance of C. perfringens C1 spores isolated from food product. The results showed that C. perfringens C1 spores produced at T = 37 °C, pH = 8, and aw = 0.997 had the highest sporulation rate and germination efficiency and lowest wet-heat resistance. A further increase in pH and sporulation temperature reduced the spore counts and germination efficiency, but enhanced spores' wet-heat resistance. By using air-drying method and Raman spectroscopy analysis, the water content, composition, and levels of calcium dipicolinic acid, proteins, and nucleic acids in spores produced under different sporulation conditions were determined. The results obtained revealed that sporulation conditions should be carefully considered during food production and processing, thus providing a novel insight into prevention and control of spores in food industry.

Highly accurate classification of biological spores by culture medium for forensic attribution using multiple chemical signature types and machine learning. Anal Bioanal Chem 2020; 412:4287-4299.

Abstract
Future proliferation of biological expertise and new technology may increasingly lower the difficulty to produce biological organisms for misuse. Rapid attribution of a biological attack is needed to quickly identify the person or lab responsible and prevent additional attacks by enabling the apprehension of suspects. Here, triplicate batches of Bacillus anthracis Sterne strain (BaSt) spores were grown in a total of seven amateur and professional media. Multiple orthogonal analytical signatures (peptides, metabolites, lipids by fatty acid methyl ester (FAME) analysis, bulk organic profile, and trace elements) were collected from the BaSt spores. The proteomics and metabolomics analyses identified promising attribution signature compounds that are unique to each of the seven production methods. In addition, while each of the signature types showed varying degrees of value individually for attributing BaSt spores to the culture medium used to prepare them, fusing results from all five signatures types to increase sourcing robustness and using a random forest sourcing algorithm yielded 100% hold-one-batch-out cross-validation classification accuracy and an average relative source probability for the correct source 5.5× higher than the most probable incorrect source. These preliminary results provide a proof-of-concept for the development of forensic examinations that can attribute biological agents to production methods for use in future investigations.
