Selenium is an essential trace mineral important for the maintenance of homeostasis in animals and humans.It evinces a strong antioxidant,anti-inflammatory and potential antimicrobial capacity.Selenium biological function is primarily achieved by its presence in selenoproteins as a form of selenocysteine.Selenium deficiency may result in an array of health disorders,affecting many organs and systems;to prevent this,dietary supplementation,mainly in the forms of organic(i.e.,selenomethionine and selenocysteine)inorganic(i.e.,selenate and selenite)sources is used.In pigs as well as other food animals,dietary selenium supplementation has been used for improving growth performance,immune function,and meat quality.A substantial body of knowledge demonstrates that dietary selenium supplementation is positively associated with overall animal health especially due to its immunomodulatory activity and protection from oxidative damage.Selenium also possesses potential antiviral activity and this is achieved by protecting immune cells against oxidative damage and decreasing viral replication.In this review we endeavor to combine established and novel knowledge on the beneficial effects of dietary selenium supplementation,its antioxidant and immunomodulatory actions,and the putative antimicrobial effect thereof.Furthermore,our review demonstrates the gaps in knowledge pertaining to the use of selenium as an antiviral,underscoring the need for further in vivo and in vitro studies,particularly in pigs. 展开更多

Mycotoxins are toxic secondary metabolites produced by filamentous fungi that are commonly detected as natural contaminants in agricultural commodities worldwide.Mycotoxin exposure can lead to mycotoxicosis in both animals and humans when found in animal feeds and food products,and at lower concentrations can affect animal performance by disrupting nutrient digestion,absorption,metabolism,and animal physiology.Thus,mycotoxin contamination of animal feeds represents a significant issue to the livestock industry and is a health threat to food animals.Since prevention of mycotoxin formation is difficult to undertake to avoid contamination,mitigation strategies are needed.This review explores how the mycotoxins aflatoxins,deoxynivalenol,zearalenone,fumonisins and ochratoxin A impose nutritional and metabolic effects on food animals and summarizes mitigation strategies to reduce the risk of mycotoxicity. 展开更多

Food-producing animals are the major reservoirs for many foodborne pathogens such as Campylobacter species, non-Typhi serotypes of Salmonella enterica, Shiga toxin-producing strains of Escherichia coli, and Listeria monocytogenes. The zoonotic potential of foodborne pathogens and their ability to produce toxins causing diseases or even death are sufficient to recognize the seriousness of the situation. This manuscript reviews the evidence that links animals as vehicles of the foodborne pathogens Salmonella,Campylobacter, Shiga toxigenic E. coli, and L. monocytogenes, their impact, and their current status. We conclude that these pathogenic bacteria will continue causing outbreaks and deaths throughout the world, because no effective interventions have eliminated them from animals and food. 展开更多

Antimicrobial resistance leads to failure of clinical antimicrobial therapy,and has raised urgent global public health concern.Humans can acquire antimicrobial resistance fromdrugs through the food chain or the environment(contaminated water,air,soil,or manure).While antimicrobials have been regular supplements in animal feed that maintain health and improve productivity of livestock,their over-use in feeding forage has led to a rise in antibacterial resistance.This review summarizes the current use of antimicrobials in livestock,the harmful effects of antimicrobial resistance,and the comprehensive combat measures. 展开更多

By measuring the quantity and ways in which antimicrobials are used, and reviewing different technical and socioeconomic factors influencing antimicrobial use at farm level, this study discusses the main knowledge gaps in antimicrobial use in food animal production and provides recommendations for future research and policy development. The review reveals that antimicrobial use in food animals exhibit strong regional and species differences, and there are still large information gaps concerning the current state of antimicrobial use. Factors associated with animal health(including antimicrobial resistance),animal health improvement, economic costs and benefits relevant to animal diseases, and potential technological alternatives or alternative systems all have an impact on antimicrobial use on the farm. There is a clear need to resolve the data gap by monitoring antimicrobial use and developing an analytical framework to better understand farmer behaviors under different technical, economic and environmental circumstances. 展开更多

Salmonella Corvallis ST1541 has recently emerged as a globally disseminated pathogenic strain that often causes severe food-borne infections.Unlike most pandemic serotypes of Salmonella,the ST1541 strains harbored ColRNA1 plasmids that contain qnr-like determinants known to be responsible for the increasing incidence of ciprofloxacin-resistant food-borne Salmonella infections.In this study,we conducted a genomic analysis of a global collection of 388 S.Corvallis ST1541 strains collected within a twenty-year period.We investigated the genetic characteristics of plasmid-mediated quinolone resistance(PMQR)plasmids harbored by these S.Corvallis strains,established a mini-mum spanning tree(MST)to determine the temporal and spatial distribution of the top 10 MST clusters,inferred a time-phylogenies for the major sub-lineages and traced the routes of international dissemination of this serotype strains.Bayesian algorithm predicted that UK might be the origin of S.Corvallis strains currently prevalent in various countries.This idea is supported by the observation of the emergence of intercontinental-disseminated clonal strains and extensive transmission of the extensive-drug resistance(XDR)-encoding plasmid pSA663.This study there-fore provides valuable insight into the evolution of globally transmitted S.Corvallis strains and suggests a need to strengthen cooperation between different countries to control the dissemination of these drug-resistant bacteria. 展开更多

Objective:To determine if meat or soy protein dietary supplementation will enhance the neuro-cognitive performance of HIV-affected children at-risk of malnutrition and food insecurity.Methods:A randomized,double-blind,controlled intervention trial evaluated the effect of nu-tritional supplementation on the neurocognitive outcomes of 49 HIV-affected school-age children in western Kenya.The intervention consisted in providing the mother,target child,and siblings with one of three isocaloric biscuit-type supplements-soy,wheat,or beef-on 5 days per week for 18 months.Neurocognitive outcomes of the target children were assessed by a battery of eight measures and followed up longitudinally for up to 24 months.Results:Mixed effects modeling demonstrated significant differences in the rates of increase over time among all three groups(F test degrees of freedom of 2,P<0.05)for Raven’s progressive matrices performance,but not for verbal meaning,arithmetic,digit span backward,forward,and total,embedded figure test,and Beery visual-motor integration scores.Conclusion:HIV-affected school-age children provided with soy protein supplementation showed greater improvement in nonverbal cognitive(fluid intelligence)performance compared with peers who received isocaloric beef or wheat biscuits.Soy nutrients may have an enhancing effect on neurocognitive skills in HIV-affected school-age children. 展开更多
