This practice encourages bacterial resistance and could lead to the evolution of resistant strains of bacteria in animals and humans as well as the fish themselves. A more judicious approach to the use of prophylactic (preventative) antibiotics is necessary.
Dr Felipe Cabello and his colleagues at New York Medical College, reported these findings in the July issue of ‘Environmental Microbiology’. It is common practice in the fish industry, particularly in developing countries, to use large amounts of antibiotics to prevent infection. The antibiotics used are often non-biodegradable and remain in the aquaculture environment for long periods of time. This encourages the growth of bacteria which can survive in the presence of antibiotics - antibiotic resistant bacteria.
Eventually this process could lead to increased antibiotic resistance in the ‘disease-causing’ bacteria (pathogens) of fish. The properties which make bacteria resistant can also be transferred to human and animal pathogens, leading to increased infectious disease in fish, animals and humans alike.
When antibiotics are mixed with fish food, residual antibiotics may be found in fish products and fish meat. People who eat these products will be inadvertently consuming antibiotics, leading to changes in their normal microbial environment, or ‘microflora’ and making them more susceptible to bacterial infection.
“If we don’t curb the heavy use of prophylactic antibiotics in aquaculture, then we will ultimately see more and more antibiotic resistant pathogens emerging, causing increased disease to fish, animals and humans alike” said Dr Cabello.
A global effort to curb the over-use of antibiotics in the rearing of finfish is essential in preventing these detrimental effects to fish, animal and human health.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
