    The news about microthings that can have a macroeffect ......

    One month old news but a new tick borne virus was discovered in Kansas

    It killed a man. Its little name is Bourbon virus

    Those ticks do carry some nasty bugs. And weird, like the one carried by the Lone star tick causing you red meat allergy.

      Ticks are indeed something to be carefull off. They are almost worst than mosquitoes when it come to infectious diseases. Between Lyme disease, Rocky fever, Anaplasmosis, Tularemia etc, the tiny bite can kill you as easilly as a bullet. Tickborne paralysis is also something. When walking in bushes, high grass or forest areas, i always advise for high boots, legging over, long pants and repellent...

        It seems I live luckily in a region where ticks aren't known to usually carry the worst of diseases, but it still creeps me out thinking such a trivial thing as an insect bite can potentially cause so much damage.

          Now, not all tiny creatures are bad.
          A new promising antibiotic has been discovered (publication occured end of february) Scientists discover a potent new antibiotic

          Scientists have discovered a powerful new antibiotic that kills an array of drug-resistant bacteria, a much-needed breakthrough that could lead to a whole new class of disease-fighting treatments.

          Let's hope the clinical trials are as spectacular...

              I heard about the proliferation of the Powassan Virus here in the north-east...those beasts scares the shit out of me...

                Not human related but an ecological disaster is unfolding in Europe with introduction of an insect borne bacteria that attacks a bunch of decorative and agricultural trees of interests.
                For now, 10% of the olive trees in the Pouille region of Italy seem impacted. And the scientists are afraid the disease will propagate itself widely.
                It's both an economical disaster (olive oil, almond trees, grape fields and citrus/organe fields are at risk and very important for meditteranean countries economies) as well as a potential ecological disaster.
                The origine comes from imported south american coffee tree.
                On a side note this shows the importance and impact of invasive species coming from other countries.

                  That's promising, and timely. In 2013 a man in New Zealand died of a stroke, but was found to be carrying a bacteria resistant to every antibiotic available. Ev.er.y antibiotic.

                  The WHO has a breakdown here of antimicrobial resistance. An important point to note for some members here, gonorrhoea may soon become entirely drug resistant.

                  So, this is terrifying.

                    For the record, in that case, there are still 3 ATB that may work : Polymixyn B, tigecycline and aztreonam but efficiency is irregular and their biodisponibility and pharmacocinetic datas make them poorly usable for some specific colonization sites.
                    In all case, the treatment is not guaranteed to work, especially on already weakened patients

                      The simple demonstration of the beauty of evolution by natural selection eh?

                      Lack of research into new antibiotics by drug companies will be the new ticking time bomb, it's estimated within 30 yrs without new drugs and rampant multi drug resistant bacteria routine opertions may carry similar dangers to 18thC medicine, and may constitute the greatest threat currently facing humanity. We may know about aseptics and prevention but everything from dental or eye surgery to ingrowing toenails, will carry a significant increase in the risk of severe life threatening infection.

                        It's also our fault. We are over-using ATBs mostly for animal farm industry. Pigs, Veals, Chickens even fishes are literaly filled with ATBs to protect them from illness preemptively because they are rised and concentrationary onditions.
                        That generates resistances and those resistances not only affect food borne bacterias but also other kinds of bacterias because the tiny bugs can exchange informations despite the specie curtain.
                        Ad on that mishandling of ATB in human medicine (you have a viral cold ? take ATB anyway, not matter it is not usuful), excreted ATB in the environement and indeed lack of research on new molecules and we are at the edge of a disaster.
                        Multidrug resistant tuberculosis, MRSA are already killing tenth of thousand in rich countries every year.
                        You can really begin to shiver when you know that MDR and XDR Yersinia pestis and Vibrio cholerae are "on the market"....waiting their turn

                          I'll be following this one Mordoror despite it being a few years since I swabbed or crossed my fingers when I opened my whole carcass results.

                            Everything from cordyceps fungii infecting ants brains, causing them to climb above the nest and die, releasing fungal spores over the nest to toxoplasma altering the behaviour of rodents (and other mammels!) making them less fearful and more risk taking, so they are more likely to get eaten by cats, the definitive host for the toxoplasma parasite. Some studies have suggested links between toxoplasma infection and schizophrenia, and significantly greater risk of road traffic accident in infected people.

                              I can now see actuaries scripting cat ownership into risk models.
