FISH & SHELLFISH IMMUNOLOGY 2015; 47:962-977. [PMID: 26529571 DOI: 10.1016/j.fsi.2015.10.038] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2015] [Revised: 10/23/2015] [Accepted: 10/27/2015] [Indexed: 06/05/2023]
Abstract
Menez Gwen (MG) and Lucky Strike (LS) deep-sea hydrothermal vents are located at 850 m and 1730 m depths respectively and support chemosynthesis-based ecosystems partially differing in heavy metal concentration, temperature range, and faunistic composition. The successfully adapted deep-sea vent mussel Bathymodiolus azoricus is found at both vent locations. In such inhospitable environments survival strategies rely on the establishment of bacteria-vent animal symbiosis In spite of the toxic nature of deep-sea vents, the problem of microbial threat and the need for immunity exist in B. azoricus. This study aims at investigating the immune system of B. azoricus from MG and LS populations by comparing immune gene expressions profiles using the deep-sea vent-related Vibrio diabolicus. Expression of nineteen immune genes was analyzed from gill, digestive gland and mantle tissues upon 3 h, 12 h and 24 h V. diabolicus challenges. Based on quantitative-Polymerase Chain Reaction (qPCR) significant gene expression differences were found among MG and LS populations and challenge times MG mussels revealed that gill and digestive gland gene expression levels were remarkably higher than those from LS mussels. Expression of Carcinolectin, Serpin-2, SRCR, IRGs, RTK, TLR2, NF-κB, HSP70 and Ferritin genes was greater in MG than LS mussels. In contrast, mantle tissue from LS mussels revealed the highest peak of expression at 24 h for most genes analyzed. The activation of immune signaling pathways demonstrated that gene expression profiles are distinct between the two mussel populations. These differences may possibly ensue from intrinsic immune transcriptional activities upon which host responses are modulated in presence of V. diabolicus. mRNA transcript variations were assessed during 24 h acclimatization taking into account the partial depuration to which mussels were subjected to. Additionally, gene expression differences may reflect still accountable effects from the presence of vent remaining microfluidic environments within the tissues analyzed.

Abstract
Vibrio metschnikovii is a food-borne pathogen found in seafood worldwide. We studied the global proteome responses of V. metschnikovii under cold stress by nano-flow ultra-high-performance liquid chromatography coupled to a quadrupole Orbitrap mass spectrometer. A total of 2066 proteins were identified, among which 288 were significantly upregulated and 572 were downregulated. Functional categorization of these proteins revealed distinct differences between cold-stressed and control cells. Quantitative reverse transcription polymerase chain reaction analysis was also performed to determine the mRNA expression levels of seventeen cold stress-related genes. The results of this study should improve our understanding of the metabolic activities of cold-adapted bacteria and will facilitate a better systems-based understanding of V. metschnikovii.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2014; 94:2630-2638. [PMID: 24473993 DOI: 10.1002/jsfa.6595] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2013] [Revised: 01/21/2014] [Accepted: 01/22/2014] [Indexed: 06/03/2023]
Abstract
BACKGROUND High hydrostatic pressure (HHP) processing is currently being used as a treatment for certain foods to inhibit spoilage organisms and control the presence of foodborne pathogens. In this study proteome profiles were performed by two-dimensional gel electrophoresis (2-DE) coupled with MALDI-TOF/TOF identification to determine the effects of HHP (50, 100, 150 and 200 MPa, each for 10 min) on Vibrio parahaemolyticus ATCC 17802 (∼8 log CFU mL⁻¹) in order to understand how it responds to mechanical stress injury. RESULTS Multiple comparisons of 2-DE revealed that the majority of changes in protein abundance occurred in a pressure-dependent fashion. A total of 18 differentially expressed protein spots were successfully identified by MALDI-TOF/TOF analysis. Moreover, quantitative RT-PCR and immunoblotting also substantiated the changes of transcriptional and translational levels of representative proteins. CONCLUSIONS Our results suggested that V. parahaemolyticus may respond to HHP treatment through suppression of membrane stability and functionality (PfaC, Alr2, MltA, PLA2 and PatH), depression of biosynthesis and cellular processes (NadB, PyrB and ArgB), decreased levels of transcription (RpoD) and translation (RpsA, RplJ and PheS), and effective activation of protein folding and stress-related elements (GroES, DnaK and GroEL). This study may provide insight into the nature of the cellular targets of high pressure and in high-pressure resistance mechanisms in V. parahaemolyticus.

Abstract
Salmonellosis is one of the most common and widely distributed foodborne diseases. The emergence of Salmonella strains that are resistant to a variety of antimicrobials is a serious global public health concern. Salmonella enterica serovar Typhimurium definitive phage type 104 (DT104) is one of these emerging epidemic multidrug resistant strains. Here we collate information from the diverse and comprehensive range of experiments on Salmonella proteomes that have been published. We then present a new study of the proteome of the quinolone-resistant Se20 strain (phage type DT104B), recovered after ciprofloxacin treatment and compared it to the proteome of reference strain SL1344. A total of 186 and 219 protein spots were recovered from Se20 and SL1344 protein extracts, respectively, after two-dimensional gel electrophoresis. The signatures of 94% of the protein spots were successfully identified through matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF MS). Three antimicrobial resistance related proteins, whose genes were previously detected by polymerase chain reaction (PCR), were identified in the clinical strain. The presence of these proteins, dihydropteroate synthase type-2 (sul2 gene), aminoglycoside resistance protein A (strA gene) and aminoglycoside 6'-N-acetyltransferase type Ib-cr4 (aac(6')-Ib-cr4 gene), was confirmed in the DT104B clinical strain. The aac(6')-Ib-cr4 gene is responsible for plasmid-mediated aminoglycoside and quinolone resistance. This is a preliminary analysis of the proteome of these two S. Typhimurium strains and further work is being developed to better understand how antimicrobial resistance is developing in this pathogen.

Abstract
Vibrio spp. have the ability to form biofilms, which may contribute to the subsequent successful colonization by microfouling and macrofouling organisms. The effects of an antifouling compound, poly-ether B, on Vibrio sp. 010 were investigated using flow cytometry, proteomics, and metabolomics. A 2-D gel-based proteomic analysis was used to identify proteins responsive to poly-ether B treatment. The profiles of biofilm metabolites were analyzed by ultra-performance liquid chromatography-mass spectrometry. Poly-ether B caused a significant reduction in viability. The proteins affected by the treatment were related to nucleotide metabolism, the glyoxylate cycle, and stress responses. Metabolites such as tripeptides, fatty acids, and quorum-sensing molecules were regulated differentially. Down-regulation of proteins and metabolites potentially led to a loss in colonisation ability, thereby affecting the structure of the biofilm. These results suggest that the proteins and metabolites identified may serve as target molecules for potent antifouling compounds.

Abstract
Vibrio anguillarum is a halophilic Gram-negative bacterium causing vibriosis in marine fish and other aquatic animals. Most bacteria have developed strategies to survive in harsh environments, and V. anguillarum also encounters various stresses in seawater and hosts. In this study, we investigated changes in protein expression of V. anguillarum in response to diverse stress conditions of temperature, pH, and NaCl. Proteins were separated by 2D-PAGE, differences in expression patterns under each of the above conditions were observed, and proteins were identified using MALDI-TOF MS/MS. We found an oxidoreductase short-chain dehydrogenase/reductase family protein (OSDR), commonly down-regulated under all applied stresses (temperature 15 °C, pH 5 or 10, and NaCl 2 M). Analysis at transcriptional level using RT-PCR showed that osdr gene expression was reduced over time under these stress conditions. Among the various stresses, pH 10 was the most effective for reduction of osdr mRNA transcription. Our findings provide a useful candidate protein for detection of environmental change using V. anguillarum.

Abstract
Two-dimensional gel electrophoresis (2DE) is a key analytical method for investigating bacterial -proteomes. The relatively simple genomes of many bacteria combined with only limited post--translational modifications of bacterial proteins mean that a significant proportion of the proteome is open to analysis by 2DE. The applications of 2DE in the field of microbiology are diverse and range from analysing physiological responses of the bacteria to environmental stress to investigating bacterial pathogenesis in human bacterial pathogens. The standard approach for 2DE in the analysis of bacterial proteins uses immobilised pH gradient (IPG) gels in the first dimension for charge separation and then an orthogonal separation, in the presence of SDS, to resolve the proteins according to their molecular mass. Protocols are presented in this chapter for small (7-cm-length IPG gel strips)- and medium (11- or 13-cm-length IPG strips)-format 2D gels using IPG gels and SDS-containing polyacrylamide slab gels for the second dimension. The application of the methods are demonstrated for the analysis of cell lysates prepared from Helicobacter pylori, although the same protocols have been used to analyse proteins from a variety of human bacterial pathogens.

Abstract
F172-8, an H(+)-ATPase-defective mutant of the glutamic acid-producing bacterium Corynebacterium glutamicum ATCC 14067, exhibits enhanced rates of glucose consumption and respiration compared to the parental strain when cultured in a biotin-rich medium with glucose as the carbon source. We conducted a comparative proteomic analysis to clarify the mechanism by which the enhanced glucose metabolism in this mutant is established using a proteome reference map for strain ATCC 14067. A comparison of the proteomes of the two strains revealed the up-regulated expression of the several important enzymes such as pyruvate kinase (Pyk), malate:quinone oxidoreductase (Mqo), and malate dehydrogenase (Mdh) in the mutant. Because Pyk activates glycolysis in response to cellular energy shortages in this bacterium, its increased expression may contribute to the enhanced glucose metabolism of the mutant. A unique reoxidation system has been suggested for NADH in C. glutamicum consisting of coupled reactions between Mqo and Mdh, together with the respiratory chain; therefore, the enhanced expression of both enzymes might contribute to the reoxidation of NADH during increased respiration. The proteomic analysis allowed the identification of unique physiological changes associated with the H(+)-ATPase defect in F172-8 and contributed to the understanding of the adaptations of C. glutamicum to energy deficiencies.
