Antibiotics in Livestock and Their Effects on the Human Health: Mini Review
Rana Md. Shohel,허선진 공주대학교 자원과학연구소 2022 자원과학연구 Vol.4 No.1
An increase in livestock then led to unsanitary conditions and disease in the animals, prompting producers to administer constant low doses of antibiotics to their animals as a prophylactic to prevent disease. However, the use of antibiotics in food production also led to the spread and development of antimicrobial resistance. Likewise, extensive antibiotic resistance has been reported for bacteria, including human pathogens, from farmed fish and market shrimp. Some of the antibiotic resistance genes identified in food bacteria have also been identified in humans, providing indirect evidence for transfer by food handling and/or consumption. However, therapeutic uses of antibiotics may cause an adverse effect on normal human microflora. Antibiotics can decrease the number of bacteria and sometimes kill the beneficial bacterial species. Basically, broad-spectrum antibiotics may have a potential adverse effect on wide range of gut flora resulting gastrointestinal disturbance. In developed countries, an assortment of systems and programs to monitor antibiotic use, as well as antibiotics resistance in food animals, food products, and humans have been implemented. Such initiatives have led to the substantial decrease of antibiotic consumption and rates of resistance in these settings. This review provides updated information on the antibiotics resistance in livestock and human health.

Reducing Veterinary Drug Residues in Animal Products: A Review
Md Shohel Rana,Seung Yun Lee,Hae Jin Kang,Sun Jin Hur 한국축산식품학회 2019 한국축산식품학회지 Vol.39 No.5
A survey we conducted suggests that the ingestion of veterinary drug residues in edible animal parts constitutes a potential health hazard for its consumers, including, specifically, the possibility of developing multidrug resistance, carcinogenicity, and disruption of intestinal normal microflora. The survey results indicated that antibiotics, parasitic drugs, anticoccidial, or nonsteroidal anti-inflammatory drugs (NSAIDs) are broadly used, and this use in livestock is associated with the appearance of residues in various animal products such as milk, meat, and eggs. We observed that different cooking procedures, heating temperatures, storage times, fermentation, and pH have the potential to decrease drug residues in animal products. Several studies have reported the use of thermal treatments and sterilization to decrease the quantity of antibiotics such as tetracycline, oxytetracycline, macrolides, and sulfonamides, in animal products. Fermentation treatments also decreased levels of penicillin and pesticides such as dimethoate, malathion, Dichlorodiphenyldichloroethylene, and lindane. pH, known to influence decreases in cloxacillin and oxacillin levels, reportedly enhanced the dissolution of antimicrobial drug residues. Pressure cooking also reduced aldrin, dieldrin, and endosulfan in animal products. Therefore, this review provides updated information on the control of drug residues in animal products, which is of significance to veterinarians, livestock producers, and consumer health.

Non-baumannii Acinetobacter species are increasingly prevalent as opportunistic pathogens in the hospitals worldwide. However, the current information of epidemiology and antimicrobial susceptibility of non-baumannii Acinetobacter species is limited in Korea. This study investigated the species distribution, antimicrobial susceptibility, and carbapenem resistance mechanisms of 65 nonbaumannii Acinetobacter isolates from three Korean hospitals during 2017 to 2020. Sixteen different Acinetobacter species were identified. Among them, A. ursingii (n = 16), A. junii (n = 11), and A. nosocomialis (n = 9) were prevalent, accounting for 55.4% of the isolates. A half (50.8%) of non-baumannii Acinetobacter isolates were susceptible to all antimicrobial agents tested. Non-baumannii Acinetobacter isolates exhibited the highest resistance rate to piperacillin (26.2%), whereas no isolates were resistant to minocycline and tigecycline. Seven isolates were resistant to carbapenems by the production of carbapenemases. Ambler class B (blaNDM-1 and blaVIM-2) and class D carbapenemase genes (blaOXA-23, blaOXA-58, blaOXA-211, and blaOXA-213) were detected. Three isolates carried two or more carbapenemase genes. One A. calcoaceticus isolate co-carried blaVOXA-58, blaOXA-213, and blaNDM-1. In conclusion, this study provides new insights into antimicrobial susceptibility and carbapenem resistance mechanisms of Korean non-baumannii Acinetobacter species. The spread of carbapenem resistance genes should be carefully monitored among non-baumannii Acinetobacter species.
