Received: 1 September 2020; Accepted: 13 October 2020; Published: 16 October 2020 Abstract: In recent years, huge amounts of antibiotics have been administered to farm animals, and as a result, residues of these antibiotics can accumulate in livestock products and, once consumed, may be transmitted to humans. Farm animals’ antibiotic treatment may therefore present a risk for consumers health, especially for children and adolescents. In children, the immune system is not fully developed, and thus, they are more susceptible than adults to resistant bacteria. A dietary exposure assessment was conducted on veterinary antibiotics found in raw pork meat among children and adolescents in Cyprus, since pork is the most consumed red meat in Cypriot population. -
The Ocean As a Global Reservoir of Antibiotic Resistance Genes
The Ocean as a Global Reservoir of Antibiotic Resistance Genes Stephen M. Hatosy,a Adam C. Martinya,b Department of Ecology and Evolutionary Biology, University of California, Irvine, California, USAa; Department of Earth System Science, University of California, Irvine, California, USAb Recent studies of natural environments have revealed vast genetic reservoirs of antibiotic resistance (AR) genes. Soil bacteria and Downloaded from human pathogens share AR genes, and AR genes have been discovered in a variety of habitats. However, there is little knowledge about the presence and diversity of AR genes in marine environments and which organisms host AR genes. To address this, we identified the diversity of genes conferring resistance to ampicillin, tetracycline, nitrofurantoin, and sulfadimethoxine in diverse marine environments using functional metagenomics (the cloning and screening of random DNA fragments). Marine environ- ments were host to a diversity of AR-conferring genes. Antibiotic-resistant clones were found at all sites, with 28% of the genes identified as known AR genes (encoding beta-lactamases, bicyclomycin resistance pumps, etc.). However, the majority of AR genes were not previously classified as such but had products similar to proteins such as transport pumps, oxidoreductases, and hydrolases. Furthermore, 44% of the genes conferring antibiotic resistance were found in abundant marine taxa (e.g., Pelagibac- http://aem.asm.org/ ter, Prochlorococcus, and Vibrio). Therefore, we uncovered a previously unknown diversity of genes that conferred an AR pheno- type among marine environments, which makes the ocean a global reservoir of both clinically relevant and potentially novel AR genes. he spread of antibiotic resistance (AR) is critically important sity of marine AR genes, and (iii) are these genes harbored by Tto human health. -

Among the different antibiotic classes, tetracyclines and sulfonamides are two of the most used for veterinary proposals. Due to the fact that these compounds are poorly absorbed in the gut of animals, a significant proportion (up to ~90%) of them are excreted unchanged, thus reaching the environment mainly through the application of manures and slurries as fertilizers in agricultural fields. Once in the soil, antibiotics are subjected to a series of physicochemical and biological processes, which depend both on the antibiotic nature and soil characteristics. Adsorption/desorption to soil particles and degradation are the main processes that will affect the persistence, bioavailability, and environmental fate of these pollutants, thus determining their potential impacts and risks on human and ecological health. -

Sulfonamides and Sulfonamide Combinations*
Sulfonamides and Sulfonamide Combinations* Overview Due to low cost and relative efficacy against many common bacterial infections, sulfonamides and sulfonamide combinations with diaminopyrimidines are some of the most common antibacterial agents utilized in veterinary medicine. The sulfonamides are derived from sulfanilamide. These chemicals are structural analogues of ρ-aminobenzoic acid (PABA). All sulfonamides are characterized by the same chemical nucleus. Functional groups are added to the amino group or substitutions made on the amino group to facilitate varying chemical, physical and pharmacologic properties and antibacterial spectra. Most sulfonamides are too alkaline for routine parenteral use. Therefore the drug is most commonly administered orally except in life threatening systemic infections. However, sulfonamide preparations can be administered orally, intramuscularly, intravenously, intraperitoneally, intrauterally and topically. Sulfonamides are effective against Gram-positive and Gram-negative bacteria. Some protozoa, such as coccidians, Toxoplasma species and plasmodia, are generally sensitive. Chlamydia, Nocardia and Actinomyces species are also sensitive. Veterinary diseases commonly treated by sulfonamides are actinobacillosis, coccidioidosis, mastitis, metritis, colibacillosis, pododermatitis, polyarthritis, respiratory infections and toxo- plasmosis. Strains of rickettsiae, Pseudomonas, Klebsiella, Proteus, Clostridium and Leptospira species are often highly resistant. Sulfonamides are bacteriostatic antimicrobials -

Dorman Received: 2 February 2016; Accepted: 26 February 2016; Published: 4 March 2016 Abstract: The widespread use of antibiotics in veterinary practice and aquaculture has led to the increase of antimicrobial resistance in food-borne pathogens that may be transferred to humans. Global concern is reflected in the regulations from different agencies that have set maximum permitted residue limits on antibiotics in different food matrices of animal origin. Sensitive and selective methods are required to monitor residue levels in aquaculture species for routine regulatory analysis. Since sample preparation is the most important step, several extraction methods have been developed. In this review, we aim to summarize the trends in extraction of several antibiotics classes from shrimps and give a comparison of performance characteristics in the different approaches. Keywords: sample preparation; extraction; aquaculture; shrimps; chromatography; antibiotics 1. Introduction According to FAO (CWP Handbook of Fishery Statistical Standards, Section J: AQUACULTURE), “aquaculture is the farming of aquatic organisms: fish, mollusks, crustaceans, aquatic plants, crocodiles, alligators, turtles, and amphibians. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc.”[1]. Since 1960, aquaculture practice and production has increased as a result of the improved conditions in the aquaculture facilities. -
