- Abstract
Importance: Antimicrobial resistance (AMR) is a serious public health threat. AMR bacteria and their resistance determinants in food can be transmitted to humans through the food chain and by direct contact and disseminate directly to the environment., Objective: This study examined the AMR characteristics and transferable R plasmids in Escherichia coli isolated from meat ducks raised in an open-house system., Methods: One hundred seventy-seven (n = 177) commensal E. coli were examined for their antimicrobial susceptibilities and horizontal resistance transfer. The plasmids were examined by PCR-based plasmid replicon typing (PBRT) and plasmid multi-locus sequence typing (pMLST)., Results: The highest resistance rate was found against ampicillin (AMP, 83.0%) and tetracycline (TET, 81.9%), and most isolates exhibited multidrug resistance (MDR) (86.4%). The R plasmids were conjugally transferred when TET (n = 4), AMP (n = 3), and chloramphenicol (n = 3) were used as a selective pressure. The three isolates transferred resistance genes either in AMP or TET. The bla CTX-M1 gene resided on conjugative plasmids. Five replicon types were identified, of which Inc FrepB was most common in the donors (n = 13, 38.4%) and transconjugants (n = 16, 31.2%). Subtyping F plasmids revealed five distinct replicons combinations, including F47:A-:B- (n = 2), F29:A-:B23 (n = 1), F29:A-:B- (n = 1), F18:A-B:- (n = 1), and F4:A-:B- (n = 1). The chloramphenicol resistance was significantly correlated with the other AMR phenotypes ( p < 0.05)., Conclusions and Relevance: The meat ducks harbored MDR E. coli and played an important role in the environmental dissemination of AMR bacteria and its determinants. This confirms AMR as a health issue, highlighting the need for routine AMR monitoring and surveillance of meat ducks., Competing Interests: The authors declare no conflicts of interest., (© 2024 The Korean Society of Veterinary Science.)

- Abstract
The advent of aquaculture has been one of the most significant shifts in world food supply during the last century. Aquaculture has rapidly expanded and become a global food industry, spurred by population expansion, increased seafood consumption, and decreased captured fisheries. Nonetheless, the exponential growth of aquaculture has emerged as a significant contributor to anthropogenic changes. Unexpectedly, the result has focused in the emergence and spread of new diseases. The Asian sea bass ( Lates calcarifer ) is an economically important species in aquaculture, contributing significantly to the global seafood market. However, bacterial diseases have emerged as a major concern, affecting both wild and cultured populations of this species. The most prevalent bacterial pathogens are streptococcus, vibriosis, nocardiosis, tenacibaculosis, and pot-belly disease. Therefore, this review aims to comprehensively analyze both emerging and non-emerging bacterial diseases affecting L. calcarifer and explore potential management approaches for their control. Through an extensive literature survey and critical evaluation of research findings, this review highlights the current understanding of bacterial diseases in L. calcarifer and proposes strategies for better disease management. In addition, this review looks at the rise and characteristics of aquaculture, the major bacterial pathogens of L. calcarifer and their effects, and the specific attributes of disease emergence in an aquatic rather than terrestrial context. It also considers the potential for future disease emergence in L. calcarifer due to aquaculture expansion and climate changes., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 Published by Elsevier Ltd.)

- Abstract
Antimicrobial agents are used to treat microbial ailments, but increased use of antibiotics and exposure to infections in healthcare facilities and hospitals as well as the excessive and inappropriate use of antibiotics at the society level lead to the emergence of multidrug-resistant (MDR) bacteria. Antimicrobial resistance (AMR) is considered a public health concern and has rendered the treatment of different infections more challenging. The bacterial strains develop resistance against antimicrobial agents by limiting intracellular drug accumulation (increasing efflux or decreasing influx of antibiotics), modification and inactivation of drugs and its targets, enzymatic inhibition, and biofilm formation. However, the driving factors of AMR include the sociocultural and economic circumstances of a country, the use of falsified and substandard medicines, the use of antibiotics in farm animals, and food processing technologies. These factors make AMR one of the major menaces faced by mankind. In order to promote reciprocal learning, this article summarizes the current AMR situation in Pakistan and how it interacts with the health issues related to the COVID-19 pandemic. The COVID-19 pandemic aids in illuminating the possible long-term impacts of AMR, which are less immediate but not less severe since their measures and effects are equivalent. Impact on other sectors, including the health industry, the economy, and trade are also discussed. We conclude by summarizing the several approaches that could be used to address this issue., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

- Abstract
Nanozymes are super-efficient nanomaterials with enzyme-like characteristics, as the name suggests. In the last decade, efforts have been made to develop "artificial enzymes," which are alternatives to natural enzymes. As nanoscience and nanotechnology advance, nanozymes, which are catalytic nanomaterials having enzyme-like properties, have fascinated researchers' attention. Nanozymes with unique physicochemical properties and nanomaterials that mimic catalytic activity have gained a special interest in the industrial sectors. However, several constraints have hampered their effective deployment in industrial processes, including denaturation, time-consuming manufacturing, overall high cost-ratio, and reutilization challenges. After a brief overview of nanozyme research, an analysis of the similarities and differences between nanozymes and natural and synthetic enzymes is presented. Because of their distinct properties, nanozymes stand out in this comparison. Nanozymes have exhibited a variety of applications leveraging the physiochemical properties of nanomaterials, ranging from in vitro detection to enzyme substitution in biological systems. In addition, nanozymes have introduced a new field called nanozymology, which blends nanotechnology with enzymology., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

- Abstract
The Spanish flu, Asian flu, Hong Kong flu, HIV/AIDS, SARS, Ebola, and Swine flu, among others, have had a significant impact on agriculture, education, the economy, and human activities, including leisureliness, shipping, healthiness, fisheries, mining, industry, and trade. Currently, manhood is dealing with a new epidemic, the infection of the latest coronavirus (2019-nCoV), which causes a deadly disease named COVID-19. This article aims to examine COVID-19's effect on agriculture, education, and the economy. There are existing estimates to conclude that the COVID-19 pandemic has a significant influence on agriculture and the food supply chain, mostly influencing food demand and, as a result, food security, with a disproportionate impact on the most disadvantaged. To overcome spread of COVID-19, a non-contact food delivery system has been used by utilizing drown for this purpose. This epidemic crisis also introduced a digital education system that is challenging for students and teachers who are not educated in it. Weak infrastructure, such as electricity, poor access to the Internet connection, and a lack of technology literacy, has hampered the online education system. Coronavirus has an undesirable influence on the global economy by affecting tourism, the financial market, commerce, shipping, manufacturing, and the service sector. The exchange market was also down during the COVID-19 pandemic. In conclusion, we should strictly follow SOP's to improve our agriculture, education, economy, and other ways of normal life. We should also be vaccinated to fulfill our all losses in different fields., (© 2021. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)
