[November 20 AFP] the large-sized flying fox which inhabits the great portion of south Africa of Sahara, The investigation report which presupposes that two kinds of animal viruses with the potential risk infected with man are carried a disease was released by English Science journal Nature Communications (Nature Communications) on the 19th.
Although ? bat is the known source of infection of animal viruses including a lethal Ebola virus, the example to which such animal viruses are infected with other mammals over the wall of a seed has occurred.
According to the paper which the veterinarian team led by Mr. Allison Peel (Alison Peel) of ? English Cambridge University (University of Cambridge) announced It is said that the straw flying fox (scientific name: Eidolon helvum) is carrying broadly this kind of viruses [ two kinds of ].
The lagos bat virus (Lagos bat virus) by which the straw flying fox which is a kind of the bat most widely distributed over ? Africa was similar to a rabies virus, It was known so far that it is the “host” of the virus of ヘニパ virus (Henipavirus) 属.
The Hendler (Hendra) virus, a ニパ (Nipah) virus, etc. used as the cause which kills a pig, a horse, and a human being in Southeast Asia or Australia belong to ヘニパ virus 属.
Although it was ?, the bat which may carry a disease hardly understood these viruses about the number of and how much it exists till the present.
The research team extracted the sample of blood and an organization from 2000 or more bats by 12 nations in order to solve this problem.
It discovered that ?, as a result the bat used as a universe were genetically similar.
As for this, these bats are very wide range, and it has proved that the reproductive activity is performed.
In the west, the behavior range of ? straw flying fox spreads, in Ethiopia, Tanzania, and south, the east spreads out from Senegal to South Africa, a maximum of 2500-km distance is moved in five months, and it has the capability to fly a maximum of 370 km in a night.
A group is sometimes formed of 1 million or more animals.
? and also a research team discovered that 34% of the bats which extracted the sample carried a disease a lagos bat virus, and 42% carried a disease the ヘニパ virus.
In spite of being seemed from this data that many bats are infected by it, comparatively few reasons have an unknown bat which seems to show the symptoms.
The paper says that that wide range viral infection has occurred between ?, however the wild animal kind which may contact man has “a meaning potentially important at a public health aspect.”
The paper has indicated that ? human being has a possibility that it may be exposed to this virus, in some situations — the urine and ふん of a bat can be passed or the bat captured and processed for meat can be touched.
In ? this time, record of man’s example of infection does not exist about which virus, either.
However, the authors of a paper fear that it may be because it is in many areas in Africa, without detecting the example of infection since the health infrastructure is not prudent.
Mr. ? Peel says that the best method of avoiding infection is only neglecting a bat contrary to many people thinking.
? said person “a bat may be slaughtered, or it may be made to distribute without thinking well, and may be coped with to eliminate from a city area.
It is indicated that but, there is proof which suggests that there is a possibility of increasing a risk of such action giving stress to a bat and carrying out spreading (to man) infection.”
Mr. Peel is advising “If the most suitable correspondence is blown by performing surveillance study continuously, raising people’s recognition so that contact with a bat may be avoided, and the bat, it is washing a wound thoroughly.”
