TL;DR: Multi-drug resistance was highly prevalent in E. coli and increasing resistance to colistin, florfenicol and ceftiofur was observed, highlighting the rising problem of antimicrobial resistance in China.

TL;DR: The timely findings of the recent emergence of tet(X4) gene in food animal support the rapid surveillance and eradication of this gene before it is established, and illustrate the paradigm shift in tigecycline resistance.

TL;DR: It is ascertained that the tet(X4) gene was not present at high prevalence across China, but was highly endemic in northwestern China, and priorities for optimising timely intervention strategies are identified.

TL;DR: A high prevalence of fluoroquinolone resistant Salmonella in chicken supply chain, threatening the treatment ofSalmonella foodborne diseases, and the emergence of a new hybrid plasmid carrying qnrS1 indicates that the recombination of plasmids carrying resistance gene might be a potential risk factor for the prevention and control strategies of drug resistance.

TL;DR: In this paper, a compound doxycycline hydrochloride injection for animals, and its preparation method is described. And the method comprises the following steps: dissolving an antioxidant in injection water, adding the above obtained aqueous solution into an organic solvent, adding doxy-cycline hydchloride and a complexing agent, adjusting the pH value, adding a metal ion chelating agent and parts of the antioxidant, adding flunixin dissolved in a proper amount of the organic solvent and uniformly mixing, filtering, filling nitrogen, and disinfecting to obtain the compound
