K pneumoniae is a major cause of hospital-acquired infections such as pneumonia, bloodstream infections, infections in new borns and intensive-care unit patients.
In some countries, because of resistance, carbapenem antibiotics would not work in more than half of people treated for K pneumoniae infections.
Resistance to antibiotics was on Wednesday declared a "major global threat" to public health by the World Health Organization (WHO).
The report brought out by the WHO has also revealed high levels of E coli resistance to third generation cephalosporins and fluoroquinolones — two important and commonly used types of antibacterial medicine in Southeast Asia region, which is home to a quarter of the world's population.
In more bad news, in some parts of the region, more than one quarter of Staphylococcus aureus infections are reported to be methicillin-resistant (MRSA), meaning that treatment with standard antibiotics does not work.
The report, "Antimicrobial resistance: global report on surveillance" published on Wednesday, has revealed that resistance is occurring across many different infectious agents specially in seven different bacteria responsible for common, serious diseases such as bloodstream infections (sepsis), diarrhoea, pneumonia, urinary tract infections and gonorrhoea.
The results are cause for high concern, documenting resistance to antibiotics, especially "last resort" antibiotics, in all regions of the world.
Resistance to one of the most widely used antibacterial medicines for the treatment of urinary tract infections caused by E coli - fluoroquinolones - is very widespread.
In the 1980s, when these drugs were first introduced, resistance was virtually zero. Today, there are countries in many parts of the world where this treatment is now ineffective in more than half of patients.
Treatment failure to the last resort of treatment for gonorrhoea-third generation cephalosporins-has been confirmed in Austria, Australia, Canada, France, Japan, Norway, Slovenia, South Africa, Sweden and the United Kingdom. More than 1 million people are infected with gonorrhoea around the world every day.
Antibiotic resistance causes people to be sick for longer and increases the risk of death. For example, people with MRSA (methicillin-resistant Staphylococcus aureus) are estimated to be 64% more likely to die than people with a non-resistant form of the infection. Resistance also increases the cost of health care with lengthier stays in hospital and more intensive care required.
"Without urgent, coordinated action, the world is headed for a post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill," says Dr Keiji Fukuda, WHO's Assistant Director-General for Health Security.
"Effective antibiotics have been one of the pillars allowing us to live longer, live healthier, and benefit from modern medicine. Unless we take significant actions to improve efforts to prevent infections and also change how we produce, prescribe and use antibiotics, the world will lose more and more of these global public health goods and the implications will be devastating."
Antibiotic resistance — when bacteria change so antibiotics no longer work in people who need them to treat infections — is now a major threat to public health.
The report reveals high levels of resistance to third generation cephalosporins in K pneumoniae throughout the WHO European Region. In some settings, as many as 60% of Staphylococcus aureus infections are reported to be methicillin-resistant (MRSA), meaning that treatment with standard antibiotics does not work.
