| transovarial transmission of gamboa virus in a tropical mosquito, aedeomyia squamipennis. | we report transovarial transmission of gamboa virus (bunyavirus) in aedeomyia squamipennis, a tropical mosquito which is active and bloodfeeding throughout the year. gamboa virus was isolated during each of the 28 months of the study from every mosquito stage, including eggs, demonstrating that vertical transmission is a maintenance mechanism of this virus. the overall minimum infection rate was 5.1/1,000 mosquitoes. identification of the 567 isolates by neutralization indicated that greater tha ... | 1989 | 2563641 |
| 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 |
| brus laguna virus, a gamboa bunyavirus from aedeomyia squamipennis collected in honduras. | a virus isolate from aedeomyia squamipennis collected in honduras in 1967 was identified as a member of the gamboa serogroup (family bunyaviridae, genus bunyavirus). this is the ninth gamboa serogroup virus and the eighth shown to be a distinct serotype. | 1988 | 2903690 |
| identification of hitherto unrecognized arboviruses from ecuador: members of serogroups b, c, bunyamwera, patois, and minatitlan. | three hundred seventy-nine virus isolates were obtained from mosquitoes collected and sentinel hamsters exposed in coastal ecuador from 1974 to 1978. these included four alphaviruses [venezuelan equine encephalitis 1b (1), venezuelan equine encephalitis 1d (35), western equine encephalitis (1) and eastern equine encephalitis (4)]; two flaviviruses [st. louis encephalitis (3) and naranjal (6)]; 11 bunyaviruses [maguari (243), playas (3), vinces (33), turlock (2), abras (5), babahoyo (3), acara (2 ... | 1983 | 6309029 |
| new genome sequences of gamboa viruses (family bunyaviridae, genus orthobunyavirus) isolated in panama and argentina. | we describe here the nearly complete open reading frame (orf) of five gamboa virus strains isolated in panama and argentina. the viruses with complete orf showed the regular genome organization observed in other orthobunyaviruses with exception to the presence of nss protein. all predicted proteins showed homology with viruses belonging to members of the family bunyaviridae. | 2014 | 25414487 |
| aedeomyia squamipennis (diptera: culicidae) in florida, usa, a new state and country record. | aedeomyia squamipennis (lynch arribalzaga) is a tropical mosquito (diptera: culicidae) found throughout most of the american tropics, from eastern mexico through argentina, including several caribbean islands. larvae are typically associated with bodies of water with dense growths of aquatic vegetation, particularly pistia stratiotes l., water lettuce. adult females feed predominantly on the blood of birds and seek hosts in forest canopies. aedeomyia squamipennis is considered an important vecto ... | 2017 | 28399225 |
| enzootic arbovirus surveillance in forest habitat and phylogenetic characterization of novel isolates of gamboa virus in panama. | landscape changes occurring in panama, a country whose geographic location and climate have historically supported arbovirus transmission, prompted the hypothesis that arbovirus prevalence increases with degradation of tropical forest habitats. investigations at four variably degraded sites revealed a diverse array of potential mosquito vectors, several of which are known vectors of arbovirus pathogens. overall, 675 pools consisting of 25,787 mosquitoes and representing 29 species from nine gene ... | 2016 | 26834200 |

| viruses isolated from aedeomyia squamipennis mosquitoes collected in panama, ecuador, and argentina: establishment of the gamboa serogroup. | twenty-four virus strains were isolated from aedeomyia squamipennis mosquitoes collected in ecuador. one additional strain each was isolated from this species from panama and argentina. all 26 isolates were shown to be related serologically to prototype gamboa virus, originally isolated from ad. squamipennis mosquitoes collected in panama. antigenic comparisons of eight strains, including prototype gamboa virus, indicated the existence of four distinct viruses. neutralization tests with sera fro ... | 1981 | 6111232 |
| characterization of the gamboa virus serogroup (orthobunyavirusgenus, peribunyaviridae family). | comprehensive comparative phylogenetic analyses were performed on 17 gamboa serogroup viruses (gamsvs) from distinct geographic regions in the americas and other representative members of the genusorthobunyavirus(peribunyaviridae), based on small (s), medium (m), and large (l) open reading frame full-length and partial sequences. genome characterization showed that the gamsvs divide into four clades or genotypes. the gamsvs have a genetic organization similar to other orthobunyaviruses, except t ... | 2018 | 29436340 |
| detection of two highly diverse peribunyaviruses in mosquitoes from palenque, mexico. | the peribunyaviridae family contains the genera orthobunyavirus, herbevirus, pacuvirus, and shangavirus. orthobunyaviruses and pacuviruses are mainly transmitted by blood-feeding insects and infect a variety of vertebrates whereas herbeviruses and shangaviruses have a host range restricted to insects. here, we tested mosquitoes from a tropical rainforest in mexico for infections with peribunyaviruses. we identified and characterized two previously unknown viruses, designated baakal virus (bkav) ... | 2019 | 31500304 |
