text: tasmanian devil milk is capable of killing the most deadly superbugs 
  thursday october   by david gutierrez staff writer tags superbugs  drug resistance  tasmanian devils naturalnews milk from tasmanian devils and other marsupials may be a natural cure for antibioticresistant infections suggests a study conducted by researchers from the university of sydney and published in the journal scientific reports the researchers found that the milk contains no fewer than six compounds capable of killing some of the worlds worst superbugs unlike placental mammals including humans which gestate their young within the mothers body marsupials give birth after just a few weeks to highly immature offspring  mobile fetuses essentially  that still need to complete significant development in their mothers pouchin particular the immune systems of newborn marsupials are highly underdeveloped because a marsupials pouch is a significantly less controlled environment than a placental mammals uterus researchers wondered if newborn marsupials might need  and get  an extra immune boost six times as potent as human milk a previous study conducted in  cataloged many of the microbes that naturally make up the microbiome of the tasmanian devils pouch these included several diseasecausing organismsthere are potential pathogens present in the devil microbiome so the fact that the underdeveloped young in the pouch dont get sick was a clue something interesting was going on coauthor emma peel said thats what inspired our most recent studyfor the new study the researchers analyzed the tasmanian devils genome for genes coding for antimicrobial peptides called cathelicidins they found that tasmanian devil milk contains six different types of cathelicidinfor comparison human milk with all its antimicrobial and immuneboosting properties contains just a single cathelicidinthe researchers artificially synthesized the peptides then tested them against several known superbugs including methicillinresistant staphylococcus aureus mrsa and enterococci the peptides killed every type of microbe they were tested against although the researchers had expected to find some antimicrobial effect the potency of the peptides surprised themwe showed that these devil peptides kill multidrug resistant bacteria peel said which is really coolmany marsupials have even more cathelicidins in their milk than tasmanian devils wallabies have eight for instance while opossums a western hemisphere species have preliminary results have also shown that similar antimicrobial peptides are found in koala milk the global threat of superbugs although mrsa has gotten most of the media attention other superbugs such as enterococci can also be highly dangerous these bacteria  which like mrsa often naturally occur on or in the human body  can cause infections at several different sites while such infections are minor if treated enterococci are growing increasingly antibiotic resistanthealth experts were alarmed recently when more strains of enterococcus started turning up resistant to the antibiotic vancomycinvancomycin is a pretty potent antibiotic and if a bug is resistant to that then there arent a lot of drug options available to you peel saidmargaret chan directorgeneral of the world health organization recently called antibiotic resistance a fundamental threat to human health development and securityand the united kingdoms review on antimicrobial resistance recently concluded that unless urgent action is taken to stem the spread of drug resistance  superbugs will kill  million people annually by  thats more than the combined death toll of cancer and diabetesshockingly that review estimated deaths from only six varieties of superbug klebsiella pneumoniae e coli mrsa hiv tb and malariaresearchers estimate that today superbugs kill only  people a year the number is expected to rise so dramatically due to the spread of drugresistance genes through microbial populations combined with the ongoing evolution of resistance to new drugsthe review on antimicrobial resistance also failed to estimate the deaths that would come from people being unable to gain medical care such as surgery or cancer treatment that would be lethal without the use of reliable antibiotics sources for this article include
