Resistance redux
نویسنده
چکیده
the human species is one of the young est forms of life on earth, yet it has become the dominant force in evolu tion. Most of the main environmental prob lems—global warming, pollution, loss of biodiversity, land erosion and the emission of greenhouse gases—are caused, either directly or indirectly, by human activities. Optimists hope that these huge environ mental changes might be at least partly reversible, if humans agree to take massive and concerted corrective action sooner rather than later. Pessimists—or perhaps realists—hold that it might already be too late, and that we are markedly changing the physical and biological environment with as yet unclear repercussions for humanity. In any case, even if humans are the dom inant species on our planet, they are not the most important from a purely biologi cal point of view. the omnipresent micro bial population is not only the oldest form of life on Earth, having emerged more than 3 billion years ago, but also the most numerous and biologically diverse, and the most able to adapt to environmental changes. According to many pundits, microbes will be the sole survivors of any global catastrophe short of the complete destruction of all life on Earth.

Pseudo-chancre redux is rare and is defined as a gummatous (tertiary stage) recurrence at the site of the primary chancre (Stokes, Beerman, and Ingraham, 1944). The condition must be distinguished clinically and nosologically from chancre redux (monorecidive), which is an infectious relapse during the early phase of syphilis, at the site of the original chancre, from which treponemes may be rec...
