Global Screening for Human Viral Pathogens
We propose a system for continuing surveillance of viral pathogens circulating in large human populations. We base this system on the physical isolation of viruses from large pooled samples of human serum and plasma (e.g., discarded specimens from diagnostic laboratories), followed by shotgun sequencing of the resulting genomes. The technology for concentrating virions from 100-L volumes was de...
متن کاملNWHC: Screening for potential human pathogens
Resident populations of Canada geese (Branta canadensis) and ducks have increased to high numbers, particularly in urban and suburban areas, throughout the United States and in other countries. The earliest complaints related to expanding goose populations, from the 1940's to the 1970's, were mainly damage to crops in populations of Canada geese using urban and suburban areas increased as did t...
متن کاملDiagnosis of plant viral pathogens
In the last ten years there has been an explosion in plant virus outbreaks, because of either direct or indirect activities of humans. The ease of transporting plant materials and virus vectors, and collecting relatives of crop plants from the wild, has spread viruses widely throughout the world. The most important step in managing a virus disease is correct identification. Tests for diagnosis ...
متن کاملViral Pathogens in Multiple Sclerosis
P HYSICIANS AND PATIENTS HAVE ALWAYS HAD A great fascination with the invisible pathogen. Koch’s criteria, set out as early as 1882, have generally been ignored, that is, a microorganism must be (1) present in every case of the disease and (2) isolated from the host with the disease and grown in pure culture, (3) the specific disease must be reproduced when a pure culture of the microbe is inoc...
متن کاملScreening of Viral Pathogens from Pediatric Ileal Tissue Samples after Vaccination
In 2010, researchers reported that the two US-licensed rotavirus vaccines contained DNA or DNA fragments from porcine circovirus (PCV). Although PCV, a common virus among pigs, is not thought to cause illness in humans, these findings raised several safety concerns. In this study, we sought to determine whether viruses, including PCV, could be detected in ileal tissue samples of children vaccin...
