Autogenous vaccination in aquaculture: A locally enabled solution towards reduction of the global antimicrobial resistance problem

Abstract Antimicrobial resistance is a global public health crisis with attention focussed on food supply as part of the ‘One Health’ integration veterinary, environmental and health. Aquaculture has been fastest growing livestock sector in recent decades critical to nutritional security many low‐ middle‐income countries (LMIC). With ready access antibiotics limited availability veterinary support, disease control poorly informed, often unrecorded high where aquaculture growth fastest. Vaccination fish LMIC locally produced autogenous vaccines against bacterial diseases may provide driven, cost‐effective means reducing antibiotic use, replicating successes achieved during Norway's industry. Autogenous vaccines, an informed programme, have several advantages terms intellectual property, efficacy flexibility. We consider example importance, including Thailand, Vietnam Indonesia. contrast success antimicrobial reduction Norwegian salmon use Chilean industry are available, finding that regulation, planning, husbandry problems increase incidence severity. identify technical, bureaucratic infrastructural transitions could facilitate implementation vaccination challenging socio‐economic backgrounds. The benefits animal welfare, transboundary biosecurity, local farmer economics, health, favour enabled solution problem resistance.

Comparative resistome analysis of Aeromonas species in aquaculture reveals antibiotic resistance patterns and phylogeographic distribution

Environmental Research, Journal Year: 2023, Volume and Issue: 239, P. 117273 - 117273

Published: Oct. 5, 2023

The overuse of antibiotics in aquaculture drives the emergence multi-drug-resistant bacteria, and antibiotic-resistant genes (ARGs) can be disseminated to other bacteria through vertical- horizontal gene transfer (VGT HGT) under selective pressure. Profiling antibiotic resistome understanding global distribution ARGs constitutes first step developing a control strategy. Hence, this study utilized extensive genomic data from hundreds Aeromonas strains profile patterns explores their association with isolation year, country, species characteristics. Overall, ∼400 genomes were used predict A. salmonicida, hydrophila, veronii, media, sobria. such as sul1, tet(A), tet(D), which display similar proportion positive among species, subjected phylodynamic phylogeographic analyses. More than hundred identified, some exhibited either species-specific or non-species-specific patterns. salmonicida media found have higher strains, might lead more distinct ARG acquisition. ∼25% tet(D) gene(s), but no significant difference was observed by species.

Effects of Antibiotic Resistance Genes and Antibiotics on the Transport and Deposition Behaviors of Bacteria in Porous Media

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(28), P. 10426 - 10437

Published: July 5, 2023

Antibiotics present in the natural environment would induce generation of antibiotic-resistant bacteria (ARB), causing great environmental risks. The effects antibiotic resistance genes (ARGs) and antibiotics on bacterial transport/deposition porous media yet are unclear. By using E. coli without ARGs as antibiotic-susceptible (ASB) their corresponding isogenic mutants with plasmids ARB, transport were examined under different conditions (1–4 m/d flow rates 5–100 mM NaCl solutions). behaviors ARB comparable those ASB antibiotic-free conditions, indicating that within cells had negligible influence solutions. Interestingly, (5–1000 μg/L gentamicin) solutions increased both more significant enhancement for ASB. This changed induced by held true solution humic acid, river water groundwater samples. enhanced via mechanisms (ARB: competition deposition sites; ASB: motility chemotaxis effects). Clearly, since likely to escape sites containing antibiotics, these locations accumulate risks increase.

Abstract The intensification of aquaculture industries around the globe has led to increased susceptibility and exposure diseases. To ensure well-being animals profitability industry, many farms resort antibiotic treatments. However, with increasing presence antimicrobial resistance (AMR), it become important regulate limit use antibiotics, especially in animal production regarding antibiotics that are deemed as critically for human health by World Health Organization (WHO). This review describes how AMR mitigation strategies have developed over time international settings they relate aquaculture. Furthermore, we analyzed different countries regions abide these statutes, well standards from a selection certification schemes. Our results show role been inexplicitly addressed guidance documents there is need further increase activities operations combating AMR, an emphasis on alternatives use.
