| [characterization and antigenic relationship of 3 new bunyaviruses in the group anopheles a (bunyaviridae) of arboviruses]. | the isolation and characterization of three new viruses obtained from the tucuruí hydroelectric dam region is reported. these three agents belong to the anopheles a serogroup, genus bunyavirus, bunyaviridae. the tucuruí (tuc), caraipé (cpe) and arumateua (art) viruses have close relationships with each other and with trombetas (tbt) virus, an anopheles a virus previously isolated in the amazon region of brazil. these viruses form the "trombetas complex". tuc, cpe and art viruses were obtained fr ... | 1992 | 1342498 |
| arbovirus investigations in argentina, 1977-1980. ii. arthropod collections and virus isolations from argentine mosquitoes. | prospective surveys for arboviruses were carried out in santa fe, corrientes, and chaco provinces, argentina, aperiodically during 1977-1980. a total of 313,233 mosquitoes and 598 biting flies other than mosquitoes were collected and tested for virus in 5,197 and 45 pools, respectively. forty virus strains were isolated, all from mosquitoes, as follows: santa fe province: 4 gamboa group viruses from aedeomyia squamipennis, 1 strain each of st. louis encephalitis virus from culex pipiens quinquef ... | 1985 | 2863989 |
| arbovirus investigations in argentina, 1977-1980. iii. identification and characterization of viruses isolated, including new subtypes of western and venezuelan equine encephalitis viruses and four new bunyaviruses (las maloyas, resistencia, barranqueras, and antequera). | forty viruses isolated from mosquitoes between 1977 and 1980 in argentina have been identified and characterized. nineteen strains of vee virus, identical by neutralization (n) tests, were shown by hemagglutination-inhibition tests with anti-e2 glycoprotein sera to represent a new subtype vi of the vee complex. rna oligonucleotide fingerprints of this virus were distinct from subtype i viruses. the virus was not lethal for english short-haired guinea pigs, indicating that it is probably not equi ... | 1985 | 2863990 |

| viruses in the anopheles a, anopheles b, and tete serogroups in the orthobunyavirus genus (family bunyaviridae) do not encode an nss protein. | viruses in the genus orthobunyavirus, family bunyaviridae, have a genome comprising three segments (called l, m, and s) of negative-sense rna. serological studies have classified the >170 named virus isolates into 18 serogroups, with a few additional as yet ungrouped viruses. until now, molecular studies and full-length s-segment nucleotide sequences were available for representatives of eight serogroups; in all cases, the s segment encodes two proteins, n (nucleocapsid) and nss (nonstructural), ... | 2009 | 19439468 |
| genetic and phylogenetic characterization of tataguine and witwatersrand viruses and other orthobunyaviruses of the anopheles a, capim, guamá, koongol, mapputta, tete, and turlock serogroups. | the family bunyaviridae has more than 530 members that are distributed among five genera or remain to be classified. the genus orthobunyavirus is the most diverse bunyaviral genus with more than 220 viruses that have been assigned to more than 18 serogroups based on serological cross-reactions and limited molecular-biological characterization. sequence information for all three orthobunyaviral genome segments is only available for viruses belonging to the bunyamwera, bwamba/pongola, california e ... | 2015 | 26610546 |
| first complete genome sequences of anopheles a virus of the genus orthobunyavirus. | here, we report the first complete genome sequence of anopheles a virus (anav) that was isolated from colombia in 1940, and we include the first description of the medium and large segments. the anav medium and large segments share the highest identity with serogroup member lukuni virus, which causes human infection. | 2017 | 29167256 |
| studies with the electron microscope of virus-host relationships in ehrlich ascites tumor cells. ii. the localization and possible development of anopheles a virus within the endoplasmic reticulum of the host cell. | evidence is presented suggesting that anopheles a virus in the ehrlich ascites tumor cell is harbored and propagated within the endoplasmic reticulum which in this system consists of an extensive canalicular network. the organization and differentiation of endoplasmic reticulum within the cell are described and the significance of such a location of virus is discussed. | 1955 | 13263479 |
| studies with the electron microscope of virus-host relationships in ehrlich ascites tumor cells. i. the identification and structure of anopheles a virus. | sections of ehrlich ascites tumor cells infected with anopheles a virus revealed particles in the cytoplasm, which were identified as the virus on the basis of their consistent size and internal structure; their high opacity in the electron beam after fixation with osmic acid; the localized occurrence, within a certain time interval following infection, of high concentrations of such particles within the cell; the absence of similar particles in uninoculated tumor cells and cells infected with o ... | 1955 | 13263478 |
