Photodegradation remains the major pathway of antibiotic removal in natural ponds. This study introduced a new method growing vegetables on bottom substrate shrimp ponds to improve sediment quality. The aim was investigate effect vegetable planting photodegradation antibiotics. characterized levels pond during this phytoremediation process and investigated content composition with without crop ...

Antimicrobial resistance is an important health issue in human and veterinary medicine. The aim of this study was to monitor the antimicrobial three most bacteria involved porcine respiratory disease. A total 465 isolates were tested during 2017–2022 period for susceptibility Actinobacillus pleuropneumoniae (n = 137), Streptococcus suis 207), Pasteurella multocida 121) by disk diffusion method....

This study describes the results of a randomized clinical trial investigating the effect of oxytetracycline treatment dose and mode of administration on the selection of antibiotic-resistant coliform bacteria in fecal samples from nursery pigs. Nursery pigs (pigs of 4 to 7 weeks of age) in five pig herds were treated with oxytetracycline for Lawsonia intracellularis-induced diarrhea. Each group...

BACKGROUND Screening and enumeration of antimicrobial resistant Escherichia coli directly from samples is needed to identify emerging resistant clones and obtain quantitative data for risk assessment. Aim of this study was to evaluate the performance of 3M Petrifilm Select E. coli Count Plate (SEC plate) supplemented with antimicrobials to discriminate antimicrobial-resistant and non-resistant ...

The case of a 59 year old man with ornithosis endocarditis and a history of contact with pheasants is reported. Treatment with oxytetracycline was not tolerated and so doxycycline was substituted. Over the two year follow up the patient's clinical condition and serial echocardiographic appearances improved and Chlamydia psittaci complement fixation titres returned to normal. Valve replacement w...

The amount of antibiotics needed to counteract frequent piscirickettsiosis outbreaks is a major concern for the Chilean salmon industry. Resistance to antibiotics may contribute to this issue. To understand the genetics underlying Piscirickettsia salmonis-resistant phenotypes, the genome of AY3800B, an oxytetracycline-resistant isolate bearing a multidrug resistance plasmid, is presented here.

In Japan, the emergence of macrolide- and oxytetracycline-resistant strains of Nocardia seriolae has previously been reported. Here, we describe the draft genome sequence of N. seriolae strain U-1, isolated in 2011 from a diseased yellowtail in Kagoshima Prefecture. The draft genome does not have any genes responsible for macrolide and tetracycline resistance.

When considering the development of antimicrobial resistance in food animals, comparing gross use estimates of different antimicrobials is of little value due to differences in potencies, duration of activity, relative effect on target and commensal bacteria, and mechanisms of resistance. However, it may be valuable to understand quantities of different antimicrobials used in different ages of ...
