Usage, residue, and human health risk of antibiotics in Chinese aquaculture: A review.
Abstract Aquaculture is a booming industry in the world and China is the largest producer and exporter of aquatic products. To prevent and treat diseases occurred in aquaculture, antibiotics are widely applied. However, the information of antibiotics used in Chinese aquaculture is still limited. Based on peer-reviewed papers, documents, reports, and even farmer surveys, this review summarized antibiotics used in Chinese aquaculture. In 2014, more than 47.4 million tonnes of farmed aquatic products were produced in mainland China. The outputs in the east and south parts of China can reach as much as 600 tim...

Effects of Menthol Supplementation in Feedlot Cattle Diets on the Fecal Prevalence of Antimicrobial-Resistant < i > Escherichia coli < /i >
by C. C. Aperce, R. Amachawadi, C. L. Van Bibber-Krueger, T. G. Nagaraja, H. M. Scott, J. Vinasco-Torre, J. S. Drouillard The pool of antimicrobial resistance determinants in the environment and in the gut flora of cattle is a serious public health concern. In addition to being a source of human exposure, these bacteria can transfer antibiotic resistance determinants to pathogenic bacteria and endanger the future of antimicrobial therapy. The occurrence of antimicrobial resistance genes on mobile genetic elements, such as plasmids, facilitates spread of resistance. Recent work has shownin vitro anti-plasmid activity of me...

Quantitative determination of sulfisoxazole and its three N-acetylated metabolites using HPLC –MS/MS, and the saturable pharmacokinetics of sulfisoxazole in mice
Publication date: 10 September 2016 Source:Journal of Pharmaceutical and Biomedical Analysis, Volume 129 Author(s): Kyungsoo Oh, Moonchang Baek, Wonku Kang Sulfisoxazole (SFX) is still used in combination with trimethoprim in cattle despite adverse drug reactions (e.g., urolithiasis). Recently, SFX is known to be a promising repositioned drug candidate for pulmonary hypertension and cancer. We developed a simultaneous determination method of SFX and its N-acetylated metabolites (N1-acetyl SFX, N1AS; N4-acetyl SFX, N4AS; diacetyl SFX, DAS) using HPLC–MS/MS for the first time, and examined the pharmacokinetics of...

Simultaneous determination of N1-acetyl sulfisoxazole and its metabolites, and relative bioavailability compare to sulfisoxazole in rats
Publication date: 10 September 2016 Source:Journal of Pharmaceutical and Biomedical Analysis, Volume 129 Author(s): Eunyoung Kim, Wonku Kang N 1-acetyl sulfisoxazole (N1AS), a dihydropteroate synthase inhibitor is known to be biotransformed primarily to sulfisoxazole, partly to N 4-acetyl sulfisoxazole (N4AS), and likely also to diacetyl sulfisoxazole (DAS) and other compounds. Although its clinical use has been limited due to urolithiasis, some countries still use the drug in combination with trimethoprim in cattle. A liquid chromatographic method using ultraviolet detection was developed for the simultaneous det...

Drug use and antimicrobial resistance among Escherichia coli and Enterococcus spp. isolates from chicken and turkey flocks slaughtered in Quebec, Canada.
The objectives were to estimate prevalence of drug use at hatchery and on farm and to identify antimicrobial resistance (AMR) in cecal Escherichia coli and Enterococcus spp. isolates and factors associated with AMR. Eighty-two chicken flocks and 59 turkey flocks were sampled. At the hatchery, the most used antimicrobial was ceftiofur in chickens (76% of flocks) and spectinomycin in turkeys (42% of flocks). Virginiamycin was the antimicrobial most frequently added to the feed in both chicken and turkey flocks. At least 1 E. coli isolate resistant to third-generation cephalosporins was present in all chicken flocks and in a ...

Non-typhoidal Salmonella serotypes, antimicrobial resistance and co-infection with parasites among patients with diarrhea and other gastrointestinal complaints in Addis Ababa, Ethiopia
Conclusions: The study demonstrated significant association of Salmonella infection with consumption of raw vegetables. There was no significant association of Salmonella infection with co-occurring parasites. The study also showed the dominance of S. Typhimurium and S. Virchow in primary health care units. Overall, prevalence of MDR was low compared to previous studies. Although their proportion was low, S. Kentucky and S. Concord demonstrated wider spectrum of MDR. Continuous monitoring of circulating serotypes, antimicrobial resistance profile and characterization on molecular resistance determinants is essential for pr...

Antimicrobial susceptibility, virulence gene profiles and molecular subtypes of Salmonella Newport isolated from humans and other sources.
Abstract Salmonella Newport (S. Newport) is a major serotype associated with human salmonellosis. A total of 79 S. Newport recovered from humans and other sources in China were characterized for antimicrobial susceptibility, virulence gene profiles and molecular subtypes using pulsed field gel electrophoresis (PFGE). Approximately 63.3% of the isolates were susceptible to all of 16 antimicrobials tested. Nearly one third of the isolates (31.6%) were resistant to sulfisoxazole, 20.3% to tetracycline and 13.9% to nalidixic acid. Twelve isolates (15.2%) were resistant to three or more antimicrobials. Among 10...

Identification of dfrA14 in two distinct plasmids conferring trimethoprim resistance in Actinobacillus pleuropneumoniae
Conclusions This is the first description of mobilizable plasmids conferring trimethoprim resistance in A. pleuropneumoniae and, to our knowledge, the first report of dfrA14 in any member of the Pasteurellaceae. The identification of dfrA14 conferring trimethoprim resistance in A. pleuropneumoniae isolates will facilitate PCR screens for resistance to this important antimicrobial.
