"When bacteria change the way they stop antibiotics from working, antibiotic resistance develops. This so-called "resistance mechanism" of
bacteria appears in different forms, but can be shared among different bacteria and spread more widely.
antibiotic resistance could lead us back to an era when even simple cuts or bruises can be fatal. "Every year, nearly 1 million people worldwide die from bacterial infections that cannot be treated with common antibiotics, "
.
it's scary because we don't have any other antibiotics to replace.
antibiotic resistance occurs when bacteria change the way they stop antibiotics from working. This so-called "resistance mechanism" of
bacteria appears in different forms, but can be shared among different bacteria and spread more widely.
antibiotic resistance could lead us back to an era when even simple cuts or bruises can be fatal.
here are five of the most feared antibiotic-resistant bacteria ever discovered in the past five years, giving us a glimpse into the problems that may be prevalent in the future: salmonella typhibet, a highly contagious bacteria that causes typhoid, a life-threatening infection that affects about 21 million people worldwide each year. about 1 percent of the
patients will die, or 223,000.
in November 2016, a type of salmonella for typhoid fever appeared in Pakistan.
it is resistant to five antibiotics, leaving only one oral antibiotic (azithromycin) to treat it. since
858 cases of infection have been reported and four deaths have been reported in pakistan alone.
worrying, the salmonella for typhoid has shifted from multidrug resistance (which is resistant to at least three antibiotics) to widespread resistance (resistant to all but two antibiotics) in a single mutation.
it does this by obtaining a piece of DNA, or plasmids, which already contain all the new resistance genes it needs. More worrying
, by discovering another plasmid with the last two antibiotic-resistant genes, the strain is now a step away from being treated with all available antibiotics.
2, Mycothum tuberculosis mycobacterium tuberculosis is the world's leading infectious disease killer, killing more than 1.7 million people each year.
one of the reasons the bacteria is so deadly is that it can be hidden in our cells.
this means that people need to take four different antibiotics for up to six months to treat tuberculosis infections.
it is estimated that up to 13 per cent of all new TB cases are MDR-TB, with the highest number of MDR-TB cases in Europe," including Russia.
this is a cause for concern, as multidrug-resistant infections require longer courses of treatment (usually 18 to 24 months) and expensive antibiotics can also cause damage to kidneys and other organs.
has now found that 6 per cent of these cases are in fact widely drug-resistant infections (all but resistance to both classes of antibiotics).
widespread drug-resistant TB has spread to more than 123 countries and regions around the world, with a treatment success rate of only 30 per cent, which is extremely worrying.
3, Klebsiella pneumoniae creagus is a bacteria commonly found in the skin, intestines and soil that can trigger a range of potentially fatal infections in people with compromised immune systems.
because the bacteria is particularly prevalent in hospitals, it is one of the most serious threats to public health resistance.
2013, 8,000 cases of Multidrug-resistant pneumonia were reported in the United States alone, with a 50 percent mortality rate for blood infections.
2016, a strain of Creebo pneumonia, which is resistant to 26 commonly used antibiotics, or trans-resistant, was discovered in the United States.
patients infected with the bacteria often die from a lack of alternative therapies.
this is not an isolated case and other bacteria have become generally resistant.
4, the widely drug-resistant pseudomonas aeruginosa, like Crebitia pneumonia, is a common bacteria that can cause infection in people with compromised immune systems.
, it is also particularly popular in hospitals.
in the United States, an estimated 51,000 cases of medical-related copper-green pseudomonas infection each year, of which about 400 are fatal.
In the past five years, British hospitals have reported 29 cases of fully drug-resistant copper-green pseudomonas infection.
copper-green pseudomonasinfection infection is also the leading cause of death in patients with cystic fibrosis.
2013, more than 42% of patients with chronic copper-green pseudomonas infection sacfibrosine used mucosin, which is known as the "last line of defense" antibiotics.
this is because most infections are resistant to all other available antibiotics.
5, Neisseria gonorrhoeae, a widely drug-resistant gonorrhoeae, estimates that there are 78 million cases of gonorrhoea nissycosis infection worldwide, which can cause gonorrhea, a sexually transmitted disease affecting both men and women.
, while not usually fatal, failure to treat them can lead to serious and permanent health problems, including infertility.
about one-third of gonorrhea Nisser infections are resistant to at least one antibiotic.
even more worrying, a new widely drug-resistant "supergorophilus" has been found to be resistant to all but one of the antibiotics.
two of the first reported cases of "super gonorrhoea nissythel" infection occurred in Australia.
this is worrying because if these people have multiple partners, the widely drug-resistant gonorrhea neseritis can spread rapidly in people.
in rare cases, untreated gonorrhea can enter the bloodstream, leading to infectious shock and death.
will future outbreaks be more serious? Indeed, bacteria have the ability to pass on antibiotic-resistant genes to other bacteria and to develop resistance on their own.
so, over time, superbugs that are resistant to all antibiotics will eventually be born.
good news is that if we use antibiotics correctly and invest in the development of new antibiotics, vaccines and diagnostic tools, we can reduce the likelihood of this happening.
