Seaweed-associated symbionts have emerged as significant sources of novel antibacterials against nosocomial pathogens. Herein, eighty-one bacterial isolates were obtained through culture-dependent isolation of seaweed symbionts from the southern coast of India. <em>Bacillus velezensis</em> SK54 represented the largest share (54 %), followed by <em>Bacillus siamensis</em> SK53 (33 %), <em>Bacillus subtilis</em> SK20 (8 %), and <em>Bacillus filamentous</em> SK55 (5 %). <em>B. siamensis</em> SK53 and <em>B. velezensis</em> SK54, which were separated from seaweeds <em>Turbinaria conoides</em> and <em>Dictyota cervicornis</em>, respectively, demonstrated clearance zones over 25 mm on spot-over-lawn assay against multiple clinical pathogens, including methicillin-resistant <em>Staphylococcus aureus</em> (MRSA) and vancomycin-resistant <em>Staphylococcus aureus</em> (VRSA). Selected isolates were sensitive to commercially available antibiotics, and no pathogenicity was observed. The isolates did not amplify pore-forming non-haemolytic haemolysin BL (<em>hbl</em>) and enterotoxin (<em>nhe</em>) genes, and haemolysis on blood agar confirmed their non-pathogenic nature. The bacterial extracts exhibited significant antibacterial activity against the tested pathogens, including MRSA and VRSA, with a minimum inhibitory concentration (MIC) range of 6.25–12.5 μg/mL. The 700 bp type-I polyketide synthase (<em>pks</em>) genes (OQ657454, OQ706631, OQ737799, and OQ834957) were amplified from the heterotrophic <em>B. siamensis</em> SK53 and <em>B. velezensis</em> SK54, with a 99 % identity in the BLAST search. The substantial antibacterial potential against drug-resistant bacteria, along with the presence of genes encoding bioactive lead molecules, suggests that these marine symbiotic bacteria, <em>B. siamensis</em> SK53 and <em>B. velezensis</em> SK54, could be effective in combating emerging antibiotic resistance.</p></div>","PeriodicalId":12673,"journal":{"name":"Gene Reports","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142171749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the limited availability of high-quality seeds of murrel and the asynchronous maturation of brooders, particularly during peak spawning seasons creates problems in aquaculture. Beta-hydroxysteroid dehydrogenases (β-HSDs) are steroidogenic enzymes involved in the biosynthesis of active steroids in gametogenesis and steroidogenesis. This study aimed to clone and characterize the full-length cDNA sequences of two crucial enzymes, 3-beta hydroxysteroid dehydrogenase (Hsd3β) and 17-beta hydroxysteroid dehydrogenase (Hsd17β). It resulted in full-length cDNA sequences for Hsd3β and Hsd17β with 1101<!--> <!-->bp and 771<!--> <!-->bp length, respectively, encoding 366 and 256 amino acids. Signal peptide analysis indicated that both proteins are secretory, and hydropathy profiles suggested their hydrophilic nature. Notably, Rossmann-fold NAD(P)(+)-binding domains characteristic of Short-chain dehydrogenases/reductases (SDR) family genes were identified in Hsd3β (between 9-355 aa) and in Hsd17β (between 10-254 aa). Gene expression analyses were performed in testes and ovaries using qPCR at three key stages: preparatory, mature, and 16 h post human chorionic gonadotropin (hCG) injection (16 hpi). Results demonstrated a significant 2-fold upregulation of Hsd17β in mature and 16 hpi testes, while Hsd3β showed a significant 10-fold upregulation in mature testes compared to premature and 16 hpi stages. Ovarian expression of Hsd3β and Hsd17β showed minimal expression upon hCG injection (<em>P</em> &lt; 0.05).

M-PCR for 21 virulence genes was performed. A triplex PCR detected phylogenetic groups A, B1, B2, and D was done. All strains were genome-sequenced, and bioinformatics analysis was performed. EAEC isolates belonged to 29 sequence types, further clustered into 11 clonal complexes, among which CC38 was the largest, containing 38 isolates mainly belonging to two ST types (ST38 and ST315). CC10 was the most diverse group, comprising 8 STs (ST43, ST2706, ST1286, ST 10, ST167, ST34, ST227, and ST4305). The most frequently detected virulence gene among the 96 clinical EAEC isolates was <em>ast</em>A (87.5%), followed by ORF3 (62.5%), and <em>aap</em> (54.1 %). ST131, known for multidrug resistance and causing various diseases, was detected in acute diarrhea cases and animal sources, underscoring its clinical significance. These findings indicate the high diversity of EAEC and different sources of unique ST types of EAEC. The study reinforces the One Health approach, highlighting the interconnection between human health, animal reservoirs, and environmental sources in EAEC transmission dynamics. The identification of EAEC strains in animals suggests the zoonotic potential of these pathogens, necessitating comprehensive surveillance and control measures.

A significant factor contributing to increasing resistance is the overexpression of chromosomally encoded efflux pumps, which expel antibiotics from bacterial cells, thereby rendering treatments less effective. The efflux pumps not only mediate resistance to antibiotics through drug efflux but also work synergistically with other resistance mechanisms, thereby doubling the resistance. Despite their crucial role in antibiotic resistance, understanding of the structure, function, mechanisms of action, and regulation of efflux pumps remains limited, which is necessary for devising effective strategies to restore drug susceptibility and to combat MDR isolates. In this context, the present study evaluated the prevalence of efflux pump overexpression in clinical <em>A. baumannii</em> isolates using phenotypic and genotypic methods and identified potential therapeutic targets employing a network-based approach. A total of 172 <em>A. baumannii</em> isolates were collected and subjected to antibiotic susceptibility tests using the Kirby-Bauer disk diffusion method. All the isolates were found to be MDR, with 94.76 % showing resistance to carbapenems.
