One of the rarified and fatal diseases that are associated with brain infection is Naegleria infection . It is cause by the amoeba named Naegleria Fowleri , also known as the brain - eating ameba . Predominantly live in the fresh water lakes , river and warm waters of the hot springs , it can get into the body through the nose , when the septic water is forcibly aspirated duringswimmingor other water sports like diving , skiing etc .
About the Amoeba and the Disease:
The brain - eat on amoeba or Naegleria Fowleri was discovered first in the year 1965 . Scientists take that the evolution of the amoeba has taken place in the United States of America , but it was first identify in Australia . The amoeba gets to the brain through the nasal cavity . However , there is a singular fact associated with this infection that it does not cause transmission in every mortal , who is exposed to it . However , there is no sure justification to this fact .
As the amoeba travels to the encephalon , it causes PAM or primary amoebic meningoencephalitis . Sometimes , this disease is also called the Naegleriasis , referring to the name of the brain - eating amoeba . Despite being rarefied , a figure of subject of Brain Eating Amoeba or Naegleriasis or PAM are reported in the USA every twelvemonth . The impacts of the disease are so rapid that it does not give much time to the patient . Hence , despite treatments , in 99 % of the case , the patients perish .
When the amoeba gets into the body , rather into the brain , it regurgitate by a normal cell division procedure , like any other amoeba . However , since it does not see a worthy atm and favorable consideration , it becomes an inactive cyst . When again the conditions are favourable , the cysts transform themselves into trophozoite , which is in fact the feeding descriptor of the ameba . One survey says that the cause why the amoeba eats the brain is that it releases two enzyme that unfreeze the brain . grant to the reputation of the CDC or the Centres for Disease Control and Prevention , only 121 cases of primary amoebic meningoencephalitis or Naegleriasis have been witness .
How does the Brain-Eating Amoeba get into the Brain?
The Brain Eating Amoeba or Naegleria Fowleri usually loves strong and moist standard pressure and can survive in temperature as hot as 113 degree Fahrenheit . It is found in –
However , simply derive into inter-group communication with this ameba is not a potential crusade of the disease . Only when the water is forced into the nozzle that it affects the person . It come in the mental capacity by migrating through the olfactory nerves . Along with H2O sports , spiritual practices and rituals that engage ablution usually are cause for this amoeba get into the body and to the brain . Since the nasal cavity has olfactory nerves that help the brain to discover or mother wit smell , through these nerves it gets to the brain . The olfactive nerves are connect with the front part of the brain that is love as the frontal lobe .
Symptoms of Brain Eating Amoeba or Naegleriasis:
The basic activeness or impact of the Brain Eating Amoeba or Naegleria Fowleri is that as it come into the brain , it considers the brainiac as its feeding component . As a resultant role , it causes destruction of brain tissue and consequential Einstein inflammation . The symptoms that are associate with this disease are : –
Within as less as two Clarence Shepard Day Jr. to 15 day , the amoeba eats the brain and the symptom are see to get apace . As a result , the infected person dies within a hebdomad or to be specific , within 5.3 days from the time of symptom onset .
Diagnosis of Brain Eating Amoeba or Naegleriasis:
PAM or primary amoebic meningoencephalitis , or the Naegleriasis should be suspected in people , especially children , who are expose to warm fresh water . Those , who are take symptom of meningitis , should be surmise of this disease . The symptoms are so non - specific that Doctor usually misidentify it or suspect the symptoms to be signs of rough-cut disease such as bacterial or viral meningitis . Routine and universal examination like stemma exam and MRI scan do not show anything extremely strange , though a high level of white blood cell , cerise blood cells and inflammation in the brain can be get word . Even Gram Staining test can not detect the ameba . Hence , a wet climb must be done to essay the motility of the ameba under the microscope .
Treatment for Brain Eating Amoeba or Naegleriasis:
As Brain Eating Amoeba or Naegleriasis is one of the rarest of diseases and also difficult to name , very few masses survive the disease , even with treatment . However , the intervention procedures for Brain Eating Amoeba are also very limited , offering only a few medicine and drug . The reason behind this is that as there are very few number of case diagnosed with this disease , and there is no scope to equate the treatment regimens .
Usually an endovenous drug amphotericin B which is used for treat fungal infection is open to a patient with PAM . However , this drug alone can not grapple , control or process PAM . It must be supported by some other drug like miltefosine that the CDC or the Centres for Disease Control and Prevention supply .
The other drug that are return with amphotericin B include voriconazole ( Vfend ) , rifampin ( Rifadin ) , or the azithromycin ( Zithromax , Zmax ) . Although there are no scientific studies and study that try the efficacy of these drugs .
Risk Factor and Prevention of Brain Eating Amoeba or Naegleriasis:
As about 60 % of the case reported for PAM or chief amoebic meningoencephalitis , or the Naegleriasis are tike , who are 13 geezerhood of historic period and immature , they are more at risk of getting infected by Brain Eating Amoeba . Moreover , 80 % cases are come up in Male . The only path to keep this disease is by quash diving , water skiing , swim underwater , and jumping in warm , still waters . specially during the late summer , it is idealistic for the brain - deplete amoeba to get into the body through nostrils and hence , staying off from warm water during this time is suggest . outwear a nose clip is even more utilitarian . It is always advisable that you utilise distilled or uninspired piddle to clean nozzle and not regular tap H2O .
It is also useful to stay protected and clean . As the brain - eating amoeba does not make it in unclouded water system , cleaning the H2O supply tanks and regale the swimming pool and wells is very important .
