Abstract
Vibrio splendidus is an opportunistic pathogen, its pathogenicity continues to be a major aquaculture disease infection problem in many parts of the world. Bacteria can form dormant and persister cells, which may be responsible for the difficulty in treating latent infections. Bacterial persister cells are a small subpopulation with high phenotypic heterogeneity that have the ability to persist in response to high concentrations of antibiotics. In our previous work, we have confirmed tetracycline could induce V. splendidus AJ01 persister cells formation. Here, we show that exogenous adenosine and/or guanosine supply restores susceptibility of AJ01 persister cells to tetracycline, leading to effective killing of this persist subpopulation upon wake-up. Mechanistically, exogenous adenosine and/or guanosine promotes the intracellular ATP level, reduces percentage of cells with protein aggresomes, and destroys membrane stability. In addition, when cells were exposed to tetracycline, we found that cells with small nucleocytoplasmic ratio is easy to survive. Overall, our results support that exogenous adenosine or guanosine could be an effective strategy for treating infections with antibiotic-persist bacteria via regulating persisters cells formation.

Abstract
A novel pathogenic strain Vibrio 20190611023 was isolated from the hepatopancreas of moribund cultured Penaeus vannamei suffering from black gill disease. This strain was identified as V. brasiliensis based on the phylogenetic analyses of 16S rDNA gene and five other housekeeping genes (i.e., gapA, ftsZ, mreB, topA and gyrB). Some biochemical features of this strain were determined with an API 20NE system, and its haemolytic activity was determined using a sheep blood agar plate. The pathogenicity of this isolate 20190611023 was confirmed by the experimental challenge tests and histopathological examinations. P. vannamei were challenged via reverse gavage with different doses of bacterial suspensions. The calculated median lethal dose (LD50 ) was (3.16 ± 1.78) × 105 CFU/g (body weight). Moreover, antibiotic susceptibility tests were performed, the results of which showed that the strain 20190611023 was sensitive to chloramphenicol, compound sulphamethoxazole, ciprofloxacin, doxycycline and oxacillin, but resistant to erythromycin, kanamycin, gentamicin, cefoperazone, ceftriaxone, cefamezin and piperacillin. To our knowledge, this is the first report for demonstrating V. brasiliensis as a shrimp pathogen, which expands the host range of V. brasiliensis infection. The present study highlights that more attention should be paid to this novel pathogen in intensive shrimp aquaculture.

Complete genome analysis of a virulent Vibrio scophthalmi strain VSc190401 isolated from diseased marine fish half-smooth tongue sole, Cynoglossus semilaevis. BMC Microbiol 2020; 20:341. [PMID: 33176689 PMCID: PMC7661262 DOI: 10.1186/s12866-020-02028-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Accepted: 10/30/2020] [Indexed: 12/12/2022] Open
Abstract
Background Vibrio scophthalmi is an opportunistic bacterial pathogen, which is widely distributed in the marine environment. Earlier studies have suggested that it is a normal microorganism in the turbot gut. However, recent studies have confirmed that this bacterial strain can cause diseases in many different marine animals. Therefore, it is necessary to investigate its whole genome for better understanding its physiological and pathogenic mechanisms. Results In the present study, we obtained a pathogenic strain of V. scophthalmi from diseased half-smooth tongue sole (Cynoglossus semilaevis) and sequenced its whole genome. Its genome contained two circular chromosomes and two plasmids with a total size of 3,541,838 bp, which harbored 3185 coding genes. Among these genes, 2648, 2298, and 1915 genes could be found through annotation information in COG, Blast2GO, and KEGG databases, respectively. Moreover, 10 genomic islands were predicted to exist in the chromosome I through IslandViewer online system. Comparison analysis in VFDB and PHI databases showed that this strain had 334 potential virulence-related genes and 518 pathogen-host interaction-related genes. Although it contained genes related to four secretion systems of T1SS, T2SS, T4SS, and T6SS, there was only one complete T2SS secretion system. Based on CARD database blast results, 180 drug resistance genes belonging to 27 antibiotic resistance categories were found in the whole genome of such strain. However, there were many differences between the phenotype and genotype of drug resistance. Conclusions Based on the whole genome analysis, the pathogenic V. scophthalmi strain contained many types of genes related to pathogenicity and drug resistance. Moreover, it showed inconsistency between phenotype and genotype on drug resistance. These results suggested that the physiological mechanism seemed to be complex.

Abstract
Members of the bacterial genus Arthrobacter sensu lato are Gram-positive actinomycetes distributed worldwide and found in numerous environments including soil, water, glacier ice, and sewage. Homologous recombination is an important driving force in bacterial evolution, but its impact on Arthrobacter sensu lato evolution is poorly understood. We evaluated homologous recombination among 41 Arthrobacter sensu lato named species, using multilocus sequence analysis (MLSA). A high level of recombination was found, associated with strong diversification and a reticulate evolutionary pattern of Arthrobacter sensu lato. We also collected a total of 31 cold-adapted Arthrobacter sensu lato strains from two cold glaciers located in northwest China and two temperate glaciers in southwest China, and evaluated their diversity and population structure by MLSA. The glacier strains displayed high diversity, but rates of recombination among the four glacier groups were quite low, indicating that barriers to homologous recombination formed in the past among the populations on different glaciers. Our findings indicate that historical glaciation events shaped the contemporary distributions, taxonomic relationships, and phylogeographic patterns of Arthrobacter sensu lato species on glaciers.

Abstract
Two strains of Gram-negative, facultatively anaerobic, slightly halophilic bacteria, isolated from healthy gilthead sea bream (Sparus aurata) cultured in Spanish Mediterranean fish farms, were different from their closest relatives, Vibrio scophthalmi and V. ichthyoenteri, by phenotypic, phylogenetic and genomic standards. The strains were negative for decarboxylase tests and lacked extracellular hydrolytic activities, but were able to ferment d-mannitol, sucrose, cellobiose and d-gluconate, among other carbohydrates. The major cellular fatty acids were C16:
1 and C16:
0, in agreement with other species of the genus Vibrio. Their 16S rRNA gene sequences were 98.4 and 97.2 % similar to those of the type strains of V. scophthalmi and V. ichthyoenteri, and the similarities using other housekeeping genes (ftsZ, rpoD, recA, mreB and gyrB) and indices of genomic resemblance (average nucleotide identity and estimated DNA–DNA hybridization) between the isolates and those type strains were clearly below intraspecific levels, supporting the recognition of the strains as members of a separate novel species. Thus, we propose the name Vibrio renipiscarius sp. nov., with DCR 1-4-2T ( = CECT 8603T = KCTC 42287T) as the type strain.
