Article Synopsis
  • The study aimed to establish epidemiological cut-off values for the minimum inhibitory concentrations (MICs) of 10 antimicrobial agents against the bacteria Vibrio parahaemolyticus using standardized testing methods.
  • Eight laboratories conducted broth microdilution tests at two different temperatures (35°C and 28°C) to assess the effect of incubation temperature on MIC values, finding that many values were consistent across both temperatures.
  • The generated data will be submitted to the Clinical and Laboratory Standards Institute to help set international standards for interpreting antimicrobial susceptibility tests for this species.

and other closely related species cause motile aeromonad septicemia, a common fish disease. The disease affects many aquaculture sectors potentially requiring antimicrobial treatments. Therefore, researchers and laboratory diagnosticians need criteria called epidemiological cutoff values (ECVs) to determine whether a bacterial isolate has developed decreased susceptibility to an antimicrobial.

, the causative agent of columnaris disease in a large variety of freshwater fish, is a major problem in commercial aquaculture. A limited number of antimicrobial therapies are available to control this disease; therefore, these agents must be used judiciously. To facilitate effective monitoring for changes in susceptibility, the Clinical Laboratory Standards Institute (CLSI) has a standard broth microdilution test method specific for .

Article Synopsis
  • The paper discusses a new method for detecting veterinary drug residues in various fish species using liquid chromatography high-resolution mass spectrometry (LC-HRMS).
  • The LC-HRMS approach allows for the simultaneous monitoring of a wider variety of compounds compared to traditional methods, enhancing food safety analysis.
  • The study successfully identified several known and new drug residues in both aquacultured and imported fish, including compounds like amoxicillin diketone and ofloxacin.

Flavobacterium columnare and F. psychrophilum are major fish pathogens that cause diseases that may require antimicrobial therapy. Choice of appropriate treatment is dependent upon determining the antimicrobial susceptibility of isolates.

The industrial chemical melamine was used in 2007 and 2008 to raise the apparent protein content in pet feed and watered down milk, respectively. Because humans may be exposed to melamine via several different routes into the human diet as well as deliberate contamination, this study was designed to characterize the effect of high dose melamine or cyanuric acid oral exposure on the pregnant animal and developing fetus, including placental transfer. Clear rectangular crystals formed following a single triazine exposure which is a different morphology from the golden spherulites caused by combined exposure or the calculi formed when melamine combines with endogenous uric acid.

A multi-laboratory broth microdilution method trial was performed to standardize the specialized test conditions required for the fish pathogens Flavobacterium columnare and F. psychrophilum. Nine laboratories tested the quality control (QC) strains Escherichia coli ATCC 25922 and Aeromonas salmonicida subsp.

Our objectives were to determine whether sedation with metomidate hydrochloride (hereafter, "metomidate") during transportation of threespot gourami Trichogaster trichopterus would prevent an increase in blood glucose levels and improve fish marketability (i.e., based on appearance and behavior) in comparison with unsedated controls.
