A pathogenicAeromonas hydrophilastrain An4 was isolated from marine catfish and characterized with reference to its proteolytic and hemolytic activity along with SDS-PAGE profile (sodium dodecyl sulphate-Polyacrylamide gel electrophoresis) of ECPs (extracellular proteins) showing hemolysin (approximately 50 kDa). Agar well diffusion assay using crude cell extract of the bacterial isolate clearly demonstrated antibacterial activity against indicator pathogenic bacteria,Staphylococcus arlettaestrain An1,Acinetobactersp. strain An2,Vibrio parahaemolyticusstrain An3, andAlteromonas aurentiaSE3 showing inhibitory zone >10 mm well comparable to common antibiotics. Further GC-MS analysis of crude cell extract revealed several metabolites, namely, phenolics, pyrrolo-pyrazines, pyrrolo-pyridine, and butylated hydroxytoluene (well-known antimicrobials). Characterization of EPS using FTIR indicated presence of several protein-related amine and amide groups along with peaks corresponding to carboxylic and phenyl rings which may be attributed to its virulent and antibacterial properties, respectively. Besides hemolysin, EPS, and protease,Aeromonas hydrophilastrain An4 also produced several antibacterial metabolites.

Indonesia has many local plants with potential as herbal antibacterial properties, one of which is the local black fruit of Wandama. The objective of this study is to determine the antibacterial activity of the extract of black fruit seed against A. Hydrophila by in vitro and FTIR by Tilapia. The benefit of this research is to make black fruit seed extract as a natural remedy against tilapia attacked by Aeromonas Hydrophila. The antibacterial activity of black fruit seed extract against A. Hydrophila is investigated in vitro and using FTIR on tilapia in this research. The aim of this study is to establish black fruit seed extract as a natural treatment for tilapia infected with Aeromonas Hydrophila. The disc approach was used to conduct the in vitro research. Agar medium was poured into a sterile petri dish, and 2 drops of bacteria from the liquid medium were uniformly distributed and cooled. On the press, disc paper with black fruit seed extract was put and incubated for 18-24 hours at 35 C. An FTS 1000 version spectrophotometer system was used for the FTIR test. For the FT-IR study, a fraction of dried black fruit seeds was used. For clear preparation, 100 mg of dry extract is condensed in KBr pellets. A specimen of loaded black fruit seed samples was analyzed using FT-IR spectroscopy with a scanning range of 400-4000 cm-1 and a resolution of 4 cm-1. The results showed that the ethyl acetate fraction produced an inhibition zone (13.65 mm), the water fraction produced an inhibition zone (11.21 mm), and the n-hexane fraction produced the weakest inhibition zone (11.21 mm) (5.31mm). The concentration test results from 125 ppm, 250 ppm, 500 ppm and 1000 ppm obtained a large inhibition zone at a concentration of 1000 ppm with an inhibition zone area of 11.43 + 0.02. The absorbance value of black fruit seed extract in ethyl acetate solvent at 3430 cm-1 revealed the absorption band with the strongest vibration of the hydroxylate (-OH) functional group, according to FTIR research. Final thoughts with an average value of 13.65 + 0.06, black fruit seed extract using ethyl acetate can inhibit A. Hydrophila bacteria.

Charybdis Japonica

The innate immune response of Charybdis japonica treated with Aeromonas hydrophila was explored using bioinformatics. Metabolomics data were integrated with a gut microbial 16S rRNA dataset, together with information on corresponding enzyme activity. The results of the study showed that after being infected with A. hydrophila, some beneficial genera of bacteria in the gut of C. japonica, such as Photobacterium, Rhodobacter, Polaribacter, Psychrilyobacter, Mesoflavibacter, Fusibacter and Phormidium, could directly inhibit Vibrio or produce extracellular polysaccharides with highly effective antibacterial properties. The intestinal probiotics of C. japonica such as Mesoflavibacter have a mutually reinforcing relationship with Phaeobacter, Colwellia, Bacillus, Psychrobacter and Cohaesibacter. Conditional pathogenic bacteria in the gut of healthy crabs may also have such a symbiotic relationship with intestinal probiotics, promoting their growth and reproduction. For example, Phormidium has a mutualistic relationship with Aeromonas and Azopira. Metabolites in the gut of C. japonica infected with A. hydrophila, including beta-alanine metabolism, nitrogen metabolism, inositol phosphate metabolism, galactose metabolism, histidine metabolism, ascorbate and arginine and proline metabolism were increased, with alanine metabolism being the most abundant. The activity of metabolite related enzymes such as lipid peroxidase, phenoloxidase, superoxide dismutase, nitric oxide synthase, glutathione transferase and mid-glutathione decreased and NO levels also decreased. The positive correlation with the probiotic flora suggests that metabolites increase with bacterial abundance and that microbial metabolites or co-metabolites can, in turn, achieve many pleiotropic effects to resist invasion by A. hydrophila. These results may contribute to further research in the resistance of C. japonica to invading pathogens.
