It will certainly cause a lot of problems but I don’t think it’ll lead to mass extinction. If this strain or any other strain with similar resistance pattern spreads globally, patients which are infected will have a much higher risk of dying from this infection. Klebsiella pneumoniae is a facultative pathogen and is frequently found as a commensal of humans. The main clinical problems are nosocomial and pediatric infections as well as infections in Et-OH abusing people. Mostly patients therefore, which are immunosuppressed.
But let’s do a theoretical experiment and let us assume, this specific Klebsiella pneumoniae isolate with its resistance to 26 antibiotics would have a higher fitness compared to the susceptible wild type bacteria. Further to that it will share the resistance by horizontal transfer within the Enterobacteriaceae or even to more distant taxa like Vibrio or Yersinia. Than we will get into serious trouble, meaning that infections, which cannot be controlled by the immune system, will become untreatable.
For mass extinction, however, a pathogen must be easily transmittable, must have a high manifestation index, and must cause severe, rapid progressive disease. All of which is not applicable for Klebsiella.
I think it’ll not lead to mass extinction where a pathogen must be easily transmittable, must have a high manifestation index, and must cause very high progressive disease. All of which is not applicable for Klebsiella
i don't think mankind needs any help from bacteria. The spiritual extinction is almost irreversible at this point; and as for the bodily extinction . . . there are many people quite good at killing other people, and opportunities for them to practice their joystick skills are plentiful.
