U.S.A. finds one kind the hereditary one can cause virus _ that children suffered from nettle rash to whiten among parent-offspring
American researchers said a few days ago, one could cause D N A that the virus that children suffered from nettle rash often passed parents when the baby was born in to be hereditary, but not infect through the blood.
Researchers find, it has this kind of virus when can cause H H V - the baby's chromosome of 6 virus of nettle rash that the majority is infected with, and have this kind of virus in the chromosome of their father or mother too, prove this is a kind of so-called heredity of kinds of departments: Namely pass ovum or sperm's heredity.
Medical pediatrics experts of centre Caroline and Hall of Rochester in New York say: "This is actually a congenital unique mechanism that infects. "
Researchers think, probably the children of 20 will nearly be with typical acute nettle rash and symptom at the same time while having a fever. Hall's research group surveys 250 babies, 85 among them carry H H V - 6 virus. Among them, 43 congenital carry, 42 will be infected with the day after tomorrow, and the great majority are congenital carry the baby (namely congenital heredity) of the virus Can all find this kind of virus in their chromosome.
Hall says, the past assumption thought: The virus is the mother-to-baby transmission taking place through the placenta. But in the case of 86, the virus actually passes the genetic stew directly hereditarily, only the case of 14 is infecting through the placenta. The result of laboratory test reveals, one party of mother or father (rather than both sides) Chromosome too carry H H V -6.
