Heliyon, Journal Year: 2024, Volume and Issue: 10(13), P. e33905 - e33905

Published: July 1, 2024

BackgroundFish contains high-quality omega-3 fatty acids, protein, vitamins, and minerals due to this it is termed as an essential component of a balanced diet. But there have been concerns raised about the risks consuming fish that contaminated with toxins such methylmercury, polychlorinated biphenyls (PCBs), dioxins, pesticides, plastic waste. Consumption containing these pollutants raising global mortality morbidity rates.Scope approachesThe review examines current research outputs on health benefits potential consumption. The also discusses various approaches mitigating problems caused by consumption, highlights roles balancing when fish.Key findings conclusionDifferent indicated contaminants cause cancer, kidney failure, adverse neurological effect, cardiovascular diseases, so vulnerable groups pregnant, child breast-feeding children. In conclusion, need get more tangible evidence advantages disadvantages consumption safeguard wellbeing society.

Vibrio pathogens and their toxins in aquaculture: A comprehensive review

Reviews in Aquaculture, Journal Year: 2024, Volume and Issue: 16(4), P. 1858 - 1878

Published: May 25, 2024

Abstract Aquaculture is an indispensable food source for the growing world population. In last decades, its intensification has increased incidence of viral and bacterial infections, emphasizing need novel disease management strategies. Vibrionaceae bacteria are widespread in aquatic environments, affecting various host species, including economically important fish, shrimp bivalves. Also, human consumption undercooked contaminated with and/or their toxins poses a threat to health, leading conditions such as gastroenteritis, wound infection sepsis. addition, small fish shrimp, open aquaculture systems, can be eaten by birds that then carry spread this pathogen livestock humans. Many produce toxins, some detrimental or even lethal hosts, others surrounding bacteria. This review provides comprehensive overview Vibrio (in)vertebrate, summarizing findings on molecular structures, mechanisms action regulation secretion processes involved. Important toxin classes microbe–host interactions, haemolytic, proteolytic MARTX discussed, along other like PirAB produced AHPND‐causing parahaemolyticus . The also emphasizes importance microbe–microbe particularly production bacteriocins species (Vibriocins) antibacterial effectors Type 6 Secretion System (T6SS). While whole genome sequencing identified putative virulence factors many remain partially characterized uncharacterized. Elucidating regulation, characteristics provide valuable information lead solutions managing pathogens aquaculture.

Prevalence, genetic diversity, and antimicrobial susceptibility of Vibrio spp. infected gilthead sea breams from coastal farms at Damietta, Egypt

BMC Veterinary Research, Journal Year: 2024, Volume and Issue: 20(1)

Published: April 1, 2024

Abstract Background Vibriosis is one of the most serious bacterial diseases and causes high morbidity mortality among cultured sea breams . This study was undertaken to track surveillance Vibrio infection its correlation environmental factors A total 115 gilthead were collected seasonally from a private earthen pond fish farm in Shatta area Damietta, Egypt September 2022 July 2023. Physicochemical parameters water analyzed, heavy metal levels measured. The samples subjected clinical, bacteriological, Enterobacterial Repetitive Intergenic Consensus (ERIC) fingerprinting, hematoxylin Eosin histopathological staining. Results results revealed significant variations quality over different seasons, addition an increase metals. Naturally infected showed external signs postmortem lesions that relevant infection. Two dominant subspecies bacteria identified: V. alginolyticus (205 isolates) fluvialis (87 isolates). PCR confirmed presence using species-specific primer collagenase at 737 bp. highest prevalence detected during summer season (57.72%), lowest observed autumn (39.75%). analysis positive relationship between temperature ( r = 0.69). On other hand, (25.30%) (10.56%), where it negatively correlated with temperatures =—0.03). ERIC fingerprinting genetic variation within isolates. Antimicrobial susceptibility testing sensitivity ciprofloxacin doxycycline, resistance amoxicillin erythromycin. multiple antibiotic (MAR) index values for ranged 0.3 0.7, multi-drug pattern least three antibiotics. Histopathological alterations affected tissues marked hemorrhage, vascular congestion, hemosiderosis infiltration. Conclusion provides insights into potential propagation waterborne environment. Ensuring environment does not serve as reservoir virulent contagious species critical concern regional aquaculture industries. Therefore, we recommend implementing context-specific monitoring tools microbial resistance.

Coral reefs are hotspots of marine biodiversity, which results in the synthesis a wide variety compounds with unique molecular scaffolds, and bioactivities, rendering an ecosystem interest. The chemodiversity stems from intricate relationships between inhabitants reef, as chemistry produced partakes intra- interspecies communication, settlement, nutrient acquisition, defense. However, coral declining at unprecedented rate due to climate change, pollution, increased incidence pathogenic diseases. Among pathogens, Vibrio spp. bacteria key players resulting high mortality. Thus, alternative strategies such application beneficial isolated disease-resilient species being explored lower burden species. Here, we apply coculturing coral-derived leverage recent advancements untargeted metabolomics discover engineerable traits. By chasing chemical change coculture, report Microbulbifer spp.-mediated degradation amphibactins, by sequester iron. Additional biochemical experiments revealed that occurs peptide backbone requires enzyme fraction Microbulbifer. A reduction iron affinity is expected loss one Fe(III) binding moiety. Therefore, hypothesize this shapes community behaviors it pertains limiting environment, survival. Furthermore, sp. suppressed natural product bacteria. Understanding mechanisms behind these interactions will enable engineering probiotic capable lowering burdens during heat waves disease.
