A brain-eating amoeba is connected its measurement to Britain because of climate change, a starring master warns.
Naegleria fowleri, which tin lurk successful pat h2o arsenic good arsenic rivers, ponds and lakes, kills up to 99 per cent of group who get infected.
The microscopic parasite enters done nan nose, crawling up nan nasal transition to invade nan brain, which it past chews and destroys.
Initial symptoms tin see a headache, fever and vomiting, earlier progressing to causing a stiff neck, disorder and a nonaccomplishment of balance.
Microbiologist Professor Naveed Khan, who has decades of acquisition researching Naegleria and different amoebae, told MailOnline that nan result successful nan immense mostly of infections is 'you die'.
The encephalon eating parasite (pictured) tin beryllium recovered globally successful freshwater, but it's only deadly to humans erstwhile it's surviving successful warmer waters of 25 to 30 degrees
While much communal successful warmer climates, Professor Khan, presently based astatine a laboratory successful Edinburgh, has antecedently seen Naegleria successful UK h2o curen sites successful London and Nottingham. That was, however, earlier nan h2o had been treated.
But he warned nan consequence posed by nan parasite, which cannot dispersed done drinking contaminated water, could beryllium rising alongside ambiance change.
Similar claims person besides been made successful nan US, pinch cases of Naegleria having dispersed northward complete nan past fewer decades.
'With London getting very lukewarm upwind now, I deliberation it is simply a superior interest present arsenic well,' Professor Khan said.
Naegleria tin beryllium recovered globally successful freshwater and soil, including successful nan UK.
In galore recorded infections, group person caught nan parasite while swimming successful unfastened caller water, specified arsenic lakes and rivers successful lukewarm climates
Professor Khan says it's only deadly to humans erstwhile nan somesthesia of nan h2o rises to supra 30 degrees.
The heat-loving parasite tin past successful acold and moreover freezing waters, according to nan US Centre for Disease Control and Prevention.
Warmer temperatures provides a much favourable situation for nan amoeba to toggle shape into an 'infective form', wherever it develops a biologic 'hook' to connect to cells lining nan nose, aiding it connected its travel to invade nan brain.
Once it reaches nan encephalon it destroys insubstantial and causes swelling, which quickly leads to decease successful arsenic small arsenic a week.
Symptoms travel connected accelerated and tin beryllium mistaken for meningitis, meaning patients consequence not having nan infection caught until its excessively precocious for treatment.
WHAT IS A BRAIN-EATING AMOEBA?
Naegleria fowleri is commonly referred to arsenic nan 'brain-eating amoeba' arsenic it tin origin a uncommon and devastating infection of nan encephalon called superior amebic meningoencephalitis (PAM).
But nan infection is very rare, and according to nan CDC, location person been astir 35 cases reported successful nan U.S. successful nan past decade.
The single-celled organism is commonly recovered successful lukewarm freshwater, specified arsenic lakes, rivers, and basking springs, arsenic good arsenic successful soil.
It usually infects group erstwhile contaminated h2o enters nan assemblage done nan nose. Once nan amoeba enters nan nose, it travels to nan encephalon wherever it causes PAM, which is usually fatal.
Infection typically occurs erstwhile group spell swimming aliases diving successful lukewarm freshwater places, for illustration lakes and rivers.
In very uncommon instances, Naegleria infections whitethorn besides hap erstwhile contaminated h2o from different sources (such arsenic inadequately chlorinated swimming excavation h2o aliases heated and contaminated pat water) enters nan nose.
You cannot get infected from swallowing h2o contaminated pinch Naegleria.
People treated pinch a operation of drugs, including antibiotics and steroids, person survived, according to nan US Centre for Disease Control and Prevention.
Naegleria cases are highly uncommon successful nan developed world, acknowledgment to chlorinated and decently treated water. Only astir 3 group successful nan US are reported to get sickened each year.
One personification successful Florida died aft being infected past March.
Officials judge they caught it by rinsing their sinuses pinch pat h2o containing nan amoeba, fixed that drinking specified h2o poses nary danger.
Such deaths are moreover rarer successful nan UK. In 1978, a young woman died aft contracting nan slayer parasite swimming successful nan Roman Baths successful Bath. The facility, which was built successful astir 70 CE connected nan tract of geothermal springs, hasn't been utilized since for bathing since, but it is still unfastened arsenic a museum.
However, Professor Khan said that arsenic summers successful nan UK slow get warmer, nan consequence presented by nan parasite increases.
In galore cases of recorded infections, group are though to person been infected while swimming successful unfastened caller water, specified arsenic lakes and rivers, successful lukewarm climates.
Such infection tin beryllium avoided by utilizing chemoreceptor plugs erstwhile swimming successful nature.
But you don't needfully request to interest astir getting nan brain-eating amoeba from properly-maintained swimming pools.
That's because chlorine is capable to termination nan parasite, Professor Khan said.
However, Naegleria is simply a consequence for group who usage pat h2o to flush their sinuses, if nan h2o is not clean. This is not a problem successful nan UK.
People typically usage a instrumentality for illustration a neti cookware to flush h2o done their sinuses to clear congestion.
However, they are urged to usage specifically sterilised h2o to debar imaginable consequence of infection from pat water.
Professor Khan, who has taught microbiology astatine universities worldwide, said nan devices tin beryllium a 'breeding ground' for nan amoeba, particularly if group time off h2o opinionated successful them for agelong periods.
'If this h2o is not clean, it tin origin superior risks,' he said.
'If nan h2o is near for a agelong clip successful nan neti pot, nan chlorine nan h2o has been traded pinch tin evaporate.'
Professor Khan did find nan encephalon eating bug successful it's dormant shape successful nan UK. But nan squad of researchers did not find nan parasite successful immoderate samples of nan h2o aft it had been treated fresh to beryllium pat water.
If you are going to clear your nasal passage, he suggests boiling nan h2o first to termination immoderate bugs and germs and letting it cool earlier utilizing it quickly after.
While moving connected a nationalist wellness task at UK h2o curen sites successful London and Nottingham between 2002 and 2008, Professor Khan did find nan dormant shape of brain-eating amoeba.
But nan researchers didn't find nan parasite successful immoderate samples of nan h2o aft it had undergone nan curen process that turns it into pat water.
However, Professor Khan is concerned this could alteration successful nan early arsenic summers get warmer.
'If location is simply a plumbing issue, nan pipes are excessively aged aliases nan h2o is travelling for a agelong distance, chlorine successful nan h2o tin evaporate by nan clip it reaches nan house,' he said reflecting connected cases of nan parasite successful Malaysia and Pakistan.
Professor Khan believes much tests for Naegleria should beryllium conducted connected UK h2o complete respective seasons because it is not presently routinely tested for.
If infection does hap symptoms of nan encephalon eating bug are difficult to spot.
For years scientists person known group who usage neti pots tin go infected pinch a brain-eating amoeba, if they are utilized incorrectly
One of nan first signs is simply a elemental headache, which tin people beryllium dismissed by some nan nationalist and medics arsenic a insignificant ailment.
As it progresses it tin origin a stiff neck. This coupled pinch a headache tin easy beryllium confused with bacterial meningitis, pinch nan diagnostic hold further lowering a patient's chances, Professor Khan warns.
He said: 'People dice wrong 24 to 72 hours by nan clip they show up to infirmary pinch symptoms.
'If you get it, 99 per cent of nan clip you will dice because location is nary effective treatment.'
He explained station mortem examinations pursuing cases of nan infection successful Malaysia and Pakistan had revealed patients had been misdiagnosed with germs meningitis erstwhile they really had Naegleria.
Professor Khan believes this happens because location isn't not capable training successful infections of nan parasite and diagnosing an infection it requires a lumbar puncture, a analyzable process involving taking cerebrospinal fluid from a patient's spine.
He said: 'Although nan amoeba is very uncommon location needs to beryllium much consciousness by physicians.'
