"The post-antibiotic apocalypse" and the "war on superbugs": catastrophe discourse in microbiology, its rhetorical form and political function
Discourses evoking an antibiotic apocalypse and a war on superbugs are emerging just at a time when so-called "catastrophe discourses" are undergoing critical and reflexive scrutiny in the context of global warming and climate change. This article combines insights from social science research into climate change discourses with applied metaphor research based on recent advances in cognitive linguistics, especially with relation to "discourse metaphors." It traces the emergence of a new apocalyptic discourse in microbiology and health care, examines its rhetorical and political function and discusses its advantages and disadvantages. It contains a reply by the author of the central discourse metaphor, "the post-antibiotic apocalypse," examined in the article
You cannot always <i>win</i>:Molecular bases of the resistance of picornaviruses to win compounds
The Picornaviridae family comprises a heterogeneous group of non-enveloped viruses with genome consisting of a single positive-sense RNA strand. Infections with picornaviruses are very common in humans, producing a spectrum of clinical outcomes, ranging from asymptomatic infection and mild respiratory illness, to meningitis, myocarditis, pericarditis, and enterovirus-induced septic syndrome. Most picornaviruses seem to develop resistance quite effectively against almost any chemotherapeutic agent that modern science has developed, presenting a truly formidable challenge to modern healthcare. For some time, it has been hoped that synthetic agents mimicking the naturally occurring sphingosine-like molecule occupying the hydrophobic pocket in the viral capsid may be useful as antiviral agents, but it has been repeatedly demonstrated that resistance to the pocket-binding antivirals develops quite rapidly and that viral strains dependent on the chemotherapeutic may emerge. Several pocket-binding pyrazole drugs have entered clinical trials so far, but as of now, none of these have been licensed by the FDA, despite the extensive clinical trials. Apparently, the search for means of prevention of infection with rhino- and enteroviruses or an etiotropic cure for the conditions related to infections with picornaviruses is still ongoing
