Eight rules for improving the quality of papers on the antimicrobial susceptibility of bacteria isolated from aquatic animals
(Inter-Research Science Publisher, 2020-04-30)The methods for antimicrobial susceptibility testing of bacteria, although relatively simple, are not robust. As a consequence, if the data generated in such tests are to be commensu- rate, all susceptibility tests must ... -
The performance of antimicrobial susceptibility testing programmes relevant to aquaculture and aquaculture products
(Food and Agriculture Organization of the United Nations (FAO), 2019)Antimicrobial susceptibility testing of bacteria isolated from aquatic animals and their environments may be performed either as part of a monitoring or surveillance programme or to provide guidance for clinical treatments ... -
Setting epidemiological cut-off values for bacteria isolated from aquatic animals: a toolbox for designing a 96-well plate for microdilution MIC assays
(European Association of Fish Pathologists, 2020-06-02)A workshop was held at the EAFP meeting in Porto to initiate discussion on the design of studies that could generate the data needed to set epidemiological cut-off values appropriate for application to antimicrobial ... -
A review of the shortcomings in the testing methods used and reporting of data in the literature on antimicrobial susceptibility
(European Association of Fish Pathologists, 2020-06-02)The susceptibility test protocols used in 186 published papers that reported 203 studies of the antimicrobial susceptibility of non-cholera Vibrio spp were examined. Only a very small percentage of the studies provided ... -
Standard protocols for antimicrobial susceptibility testing of Vibrionaceae isolated from aquatic animals
(European Association of Fish Pathologists, 2018-07-18)A review of the relevant literature has shown that it is safe to recommend that the antimicrobial susceptibility of the species of the Vibrionaceae most commonly isolated from aquatic animals can be established using ... -
Influence of incubation time on antimicrobial susceptibility testing of pathogenic Vibrio anguillarum and Vibrio vulnificus isolated from fish
