"Dodelijke" rota virus....een genegeerde zeer effectieve behandeling

Rotavirus [diarrhoea !!] associated with blood group type A

Very interesting ,but far more important is the treatment.[see article [resent!] below the blood group article[
The treatment can be given for any kind of diarrhoea

Deadly Virus Linked to Your Blood Type


(Ivanhoe Newswire) – An estimated 500,000 people worldwide die from rotavirus every year. Rotavirus is a major intestinal pathogen that is the leading cause of severe dehydration and diarrhea in infants around the world.

Some strains of rotavirus find their way into the cells of the gastrointestinal tract by recognizing antigens associated with the type A blood group – histo-blood group antigen A—  a finding that represents a new paradigm in understanding how this gut pathogen infects humans.

“The structure of a key part of a strain of the virus known as P[14] provides a clue to how the virus infects human cells,” said Dr. B. V. Venkataram Prasad, professor of biochemistry and molecular biology at Baylor College of Medicine and the report's corresponding author. In strains of rotavirus that infect animals, the top of a spike on the virus attaches to the cell via a glycan (one of many sugars linked together to form complex branched-chain structures) with a terminal molecule of sialic acid. The same did not appear to be true of virus strains that infect humans, and scientists believed the human rotavirus strains were bound to glycans with an internal sialic acid molecule, but they did not know how this occurs.

In collaboration with the laboratory of Dr. Mary Estes, professor of molecular virology and microbiology at BCM, Prasad and his colleagues found that laboratory cells modified to express the histo-blood group antigen A were easily infected by this rotavirus strain. Cells that lacked this antigen were not easily infected.
An antibody to the histo-blood group antigen A blocked infection by the virus into human intestinal cells in culture.

“Further studies identified a second rotavirus strain P[9] that uses the histo-blood group antigen as a receptor,” Prasad was quoted as saying.

The authors found humans infected with the P[14] strain had type A blood, but more studies are needed to confirm the connection.

Larger populations of infected individuals need to be studied to determine if there is a clear association of these virus strains using histo-blood group antigens as a receptor," they said.
This finding raises questions about why humans developed different blood groups, Prasad said. It may be an evolutionary change that occurred after the pathogen first invaded human cells.

A short introduction and summary.
Even in “developed” countries rota virus can cause serious diarrhoea and  is difficult to treat, at least that is what the medical text books write until now.
Wikipedia states: Treatment of acute rotavirus infection is nonspecific and involves management of symptoms and, most importantly, maintenance of hydration
This article I am sending you is to show you that this is half of  the "truth"
There is good and effective treatment for rota virus diarrhoea in addition to the important treatment with ORS [ search my yahoo group to read about ORS about which I wrote in length] and indeed I am surprised that nobody “edited” / added to the article on Wikipedia and corrected the word “non specific" If you don’t have some of the Brazilian plants "at hand" then one can get easily in Israel and Europe a  tincture of Tormentilla  and Nutmeg as aspice with which I have excellent experience in cases of severe diarrhoea [also when the diagnosis “rota” was made]
The main sentence in the article below:
 ..............Our results indicate that the extracts of Artocarpus integrifoliaMyristica fragrans and Spongias lutea  can be useful in the treatment of human diarrhea if the etiologic agent is a rotavirus.
Spondias,also called hogplum, is an excellent herbal antibiotic and I wish it was available in Israel.                                        Some patients ordered this on my suggestion.[...........The extracts of the leaf of Spondias mombin exhibited wide spectrum antibacterial effects comparable to those of Ampicillin and Gentamycin.]
Myristica fragrans is simple the same as nutmeg and many patients got telephone advise from me to use nutmeg for diarrhoea.[nutmeg is a “sam” so a very little bit should be used [pinch]] It is extremely useful!

Acute diarrhea, especially in children, is a very common disease with worldwide distribution and with a significant public health impact. Rotaviruses have been recognized as the major agents of diarrhea in infants and young children in developed as well as developing countries. In Brazil, diarrhea is one of the principal causes of death, mainly in the infant population. To fight diarrhea, traditional Brazilian medicine uses a great variety of plants. In this work, 12 medicinal plant species were screened for simian (SA-11) and human (HCR3) rotaviruses inhibition in vitro. At non-cytotoxic concentrations, the extracts from Artocarpus integrifolia L. (Moraceae) bark (480 μg/ml) and Spondias lutea L. (Anacardiaceae) leaves (160 μg/ml) had antiviral activity against both viruses. They showed inhibition of 99.2% and 97%, respectively, for human rotavirus, and 96.4% and 96.2% for simian rotavirus. The extracts from Myristica fragrans Houtt (Myristicaceae) seeds (160 μg/ml) and Spongias lutea bark (40 μg/ml) inhibited human rotavirus (90% and 82.2% inhibition, respectively), whereas the extracts from Anacardium occidentale L. (Anacardiaceae) leaves (4 μg/ml) and Psidium guajavaL. (Myrtaceae) leaves (8 μg/ml) showed activity only against simian rotavirus (82.2% and 93.8% inhibition, respectively). Our results indicate that the extracts of Artocarpus integrifoliaMyristica fragrans and Spongias lutea can be useful in the treatment of human diarrhea if the etiologic agent is a rotavirus.
