Infections from Virus Arbor: General Observations
Abstract
The Arbor viruses -- from English, arthropod borne -- are those which multiply in the bodies of hematophagous arthropods, in which they do not cause signs of illness or visible tissue lesions; in addition, they are capable of producing symptomatic infections in some vertebrates, such as birds and mammals. The Arbor viruses are not transmitted directly from vertebrate to vertebrate, but need the help of arthropod carriers. The vertebrate host, in whose blood the virus circulates, is the source of infection of the arthropod which can in its turn transmit the virus to new hosts by means of a bite. The Arbor viruses are grouped according to the ecological relations of carrier and host, the former arthropod, and the latter vertebrate. From the immunological point of view they are divided into four main groups: A, B, C, and Bunyamwera. The large taxonomic groups were formed taking on the basis of hemagglutination reaction. In addition to the antigenic relations which exist between them, the Arbor viruses have common properties: their genetic material is made up of ribonucleaic acid, their size varies between 20 and 100 milimicrons; they multiply in the nucleus and cytoplasm of the cell; and they are sensitive to ether and sodium desoxycolate.
