The World Health Organization is sounding the alert about a “ hypervirulent ” superbug . The agency has received increasing reports of people being infected by worrying strain ofKlebsiella pneumoniae — strains that can jib the last remaining antibiotics available against the bacterium and can severely sicken anyone . Little is experience about far-flung or vulgar these bacteria are , so the WHO is push for countries to ill-treat up surveillance of the scourge .
K. pneumoniaeis a ubiquitous bacteria , commonly found in the soil and as part of the human microbiota , a.k.a . the neighborhood of harmless and beneficial bacterium that live on or in our bodies . WhileK. pneumoniaedoesn’t usually stir up trouble when it ’s living in our oral cavity , cutis , or guts , it can sometimes spark malady , particularly when it ends up in our lung or other parts of the body . As a germ , K. pneumoniaeis typically an opportunistic transmission , sicken people who are already in poor health and/or have dampen immune systems .
Like many dangerous bacterium , K. pneumoniaehas steadily develop to resist the most common antibiotics used to treat it , already making it a serious job . But in recent year , doctors have take off to more and more come acrossK. pneumoniaestrains that not only resist carbapenem antibiotics — potent drug that are often a last resort treatment for superbugs — but can make spartan infections in both immunocompromised and healthy citizenry . These strains have been mint hypervirulentK. pneumoniaesequence type 23 , or hvKp ST23 .

This calendar week , the WHOissueda grave accent update on the place . In light of these increasing reports , the WHO ’s Global Antimicrobial Resistance and Surveillance System on Emerging Antimicrobial Resistance Reporting ( GLASS - EAR ) sent out a request to countries around the worldly concern earlier this yr , asking whether they had spotted recent typesetter’s case of hvKp ST23 in their backyard . Of the 43 countries that respond , 16 reported cases of hvKp , including the U.S. , Canada , the UK , and Japan , while 12 describe cases of hvKp ST23 specifically . But even these cases are only the bakshis of the iceberg lettuce , feed the lack of tools needed to dependably and quickly detect these infection , the WHO find .
“ Globally , there is no systematic surveillance that allows for the workaday identification and data collection of hvKp strains , ” the organization said in its report . “ designation of hvKp is challenging given that it is find out by usable testing ground capacity to perform genomic sequence tests or analysis of specific markers that may indicate hypervirulence , so the preponderance of hvKp - associated infection may be underrate . ”
For now , the WHO has evaluate a restrained risk level for hvKp ST23 , while acknowledging that much more data will be needed to infer just how gravid of a problem it really is — and how it could become in the near time to come . As a result , the WHO is forebode for countries to better their surveillance efforts of hvKp strains , which should admit raising awareness of it among clinician , examination labs , and public wellness systems .
“ WHO urge that Member States progressively increase their laboratory diagnostic capacity to allow for the former and reliable recognition of hvKp , as well as reinforce research laboratory capacities in molecular testing and detection and analysis of relevant virulence gene in addition to resistance genes , ” the organization pronounce .
