16 Routine application of antimicrobials is the current treatment of choice for rainbow trout 17 fry syndrome (RTFS) or bacterial coldwater disease (BCWD) caused by Flavobacterium 18 psychrophilum. In this study, the antimicrobial susceptibilities of 133 F. psychrophilum 19 isolates, 118 of which were from the UK, were evaluated by broth microdilution and disc 20 diffusion methods following VET...

OBJECTIVES To determine the prevalence of antibiotic-resistant faecal Escherichia coli from adult volunteers from urban (U) areas in Kenya, Mexico, Peru and the Philippines, and non-urban (NU) locations in Curacao, Mexico, Venezuela, Ghana, Zimbabwe and the Philippines. METHODS Faecal samples of adult volunteers (n=1290) were analysed in one laboratory for the presence of antimicrobial-resist...

introduction: antibiotics have the potential to adversely affect the microbial community. for anaerobic digestion, a sufficient methanogenic population needs to be preserved in the system. the main aim of this study was determination of inhibitory concentration of oxytetracycline on methanogenic bacteria. methods: a 120 ml jacketed bioreactor with a 90 ml working volume was inoculated granular ...

During a previous study1 we had used oxytetracycline in conjunction with other antituberculosis drugs for the treatment of tuberculous infection. This study proved thai oxytetracycline may be employed to great advantage as an ancillary drug along with isoniazid, streptomycin or viomycin. While using oxytetracycline in this way, and over a considerable period of time, we were impressed with its ...

The use of oxytetracycline for preventing and controlling bacterial pathogens in salmon farming is frequent in Chile, yet no studies have been performed to evaluate the ecological impact of its intensive and prolonged use. In this work, the frequency of oxytetracycline-resistant bacteria from water, pelletized feed and fingerlings from four Chilean freshwater Atlantic salmon farms, as well as t...

The aim of this study was to explore the bioequivalence of long-acting oxytetracycline in two formulations, a reference formulation (Terramycin 20% LA, Pfizer) and a test one (Kangtekang 20% LA, Huishen). Both formulations were administered intramuscularly at 20 mg/kg body weight at each of 24 healthy animals during a two-period crossover parallel experimental design. The oxytetracycline (OTC) ...

Growth behavior of five lactic acid bacteria previously isolated from Persian sturgeon (Acipenser persicus), were evaluated at different pH, temperature and salt concentrations. Also, antibacterial activity of extracellular products (ECPs) of this LAB were assessed to Aeromonas hydrophila . Further, their antibiotic susceptibility was determined with some commonly used antibiotics in aquacultur...
