When treating an infection, physicians may face a choice between using a bactericidal (bacteria-killing) drug, a bacteriostatic (bacteria-inhibiting) drug or a combination of the two. The solution is not always obvious, particularly since a drug that is bactericidal for one strain of bacteria may only inhibit the growth of another strain, according to an article in the November 1 issue of Clinical Infectious Diseases, now available online.
Although it might seem logical that bactericidal drugs would be preferable to bacteriostatic drugs, the type of infection is important in determining which kind of drug to use. Endocarditis seems to be best treated by bactericidal drugs. Meningitis is another candidate for bactericidal drugs. Strikingly, a bacteriostatic drug can antagonize the action of a bactericidal one in the treatment of meningitis. In treating urinary tract infections and preventing staphylococcal wound infections, studies have shown that bacteriostatic drugs work as well as bactericidal drugs.
In central nervous system infections, a rapidly bactericidal drug can release bacterial products that stimulate inflammation. For this reason, it is recommended that corticosteroids be given at the same time as a bactericidal antibiotic for bacterial meningitis. Certain bacteriostatic drugs may be preferable in cases of streptococcal and clostridial gangrene, because they inhibit the production of the toxins that cause much of the morbidity.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
