Quantitative analysis of syncytium-inducing and non-syncytium-inducing virus in patients infected with human immunodeficiency virus type 1.
Among 75 consecutive human immunodeficiency virus type 1 (HIV-1)-infected patients with moderate and advanced immunosuppression, those harboring syncytium-inducing (SI) HIV-1 had a lower CD(4+)-cell count (145 versus 278 cells per microliter, P < 0.001) and 10-fold-higher virus titers than patients with non-SI HIV-1 (398 versus 39 infectious units per 10(6) CD4+ lymphocytes; P < 0.001). In pati...
متن کاملNon-pathogenic reoviruses of leafhoppers and planthoppers
Reoviruses of hoppers are reviewed with emphasis on their transmission, classification, and evolution. Plant reoviruses multiply in both plants and hopper vectors, whereas three non-pathogenic reoviruses are known; leafhopper A virus, Peregrinus maidis reovirus, and Nilaparvata lugens reovirus (NLRV), that do not appear to cause disease in their insect hosts, and do not multiply in plants but s...

15 صفحه اولDifferential coreceptor expression allows for independent evolution of non-syncytium-inducing and syncytium-inducing HIV-1.
We demonstrated previously that CD45RA(+) CD4(+) T cells are infected primarily by syncytium-inducing (SI) HIV-1 variants, whereas CD45RO(+) CD4(+) T cells harbor both non-SI (NSI) and SI HIV-1 variants. Here, we studied evolution of tropism for CD45RA(+) and CD45RO(+) CD4(+) cells, coreceptor usage, and molecular phylogeny of coexisting NSI and SI HIV-1 clones that were isolated from four pati...
متن کاملIsolation and characterization of a gene involved in hemagglutination by an avian pathogenic Escherichia coli strain.
In this article, we report the isolation and characterization of a gene that may be important in the adherence of avian pathogenic Escherichia coli to the avian respiratory tract. The E. coli strain HB101, which is unable to agglutinate chicken erythrocytes, was transduced with cosmid libraries from the avian pathogenic E. coli strain chi 7122. Enrichment of transductants that could agglutinate...
