In silico analysis of AhyI protein and AI-1 inhibition using N-cis-octadec-9z-enoyl-l-homoserine lactone inhibitor in Aeromonas hydrophila.

AhyI is homologous to the protein LuxI and is conserved throughout bacterial species including Aeromonas hydrophila. A. hydrophila causes opportunistic infections in fish and other aquatic organisms.

Proteomics analysis reveals the effect of Aeromonas hydrophila sirtuin CobB on biological functions.

Our previous studies have profiled lysine acetylation and succinylation modifications in Aeromonas hydrophila protein and have found that CobB may be involved in lysine deacylation; however, its effects on bacterial biological function are still unknown. In this study, a data-independent acquisition (DIA)-based proteomics method was used to compare the protein abundance between cob-deleted mutants and wild-type strains. Of the total 2385 identified proteins, 385 were found to have increased abundance, while only 46 showed decreased abundance.

Four LysR-type transcriptional regulator family proteins (LTTRs) involved in antibiotic resistance in Aeromonas hydrophila.

Aeromonas hydrophila is a Gram-negative bacterium that causes serious infections in aquaculture and exhibits significant multidrug resistance. The LysR-type transcriptional regulator (LTTR) family proteins are a well-known group of transcriptional regulators involved in diverse physiological functions. However, the role of LTTRs in the regulation of bacterial resistance to antibiotics is still largely unknown.

SWATH based quantitative proteomics analysis reveals Hfq2 play an important role on pleiotropic physiological functions in Aeromonas hydrophila.

The RNA-binding protein Hfq protein is a well-characterized post-transcriptional regulator and plays an important role in the regulation of various physiological functions. Most bacterial genomes have only one copy of hfq, but a few bacterial species carry another distinct copy of hfq (hfq2) on the chromosome. However, the physiological properties of Hfq2 remain elusive.

Reprint of: Quantitative proteomic analysis reveals that chemotaxis is involved in chlortetracycline resistance of Aeromonas hydrophila.

Unlabelled: In recent years, Aeromonas hydrophila, which has been classified as a food borne pathogen, has presented with increased levels of antibiotic resistance, with the mechanisms of this resistance being poorly understood. In this study, iTRAQ coupled mass spectrometry was employed to compare differentially expressed proteins in chlortetracycline (CTC) resistant A. hydrophila relative to a control strain.
