| a novel type d simian retrovirus naturally infecting the indian hanuman langur (semnopithecus entellus). | as a simian species, the langurs are not known to harbor simian retroviruses, except for one report on a simian type d endogenous retrovirus from the spectacled langur (trachypithecus obscurus) from malaysia. the present report describes for the first time natural infection of the common hanuman langur (semnopithecus entellus) from india by a novel simian retrovirus (srv). the new srv is phylogenetically related to but distinct from the three molecularly characterized serotypes, srv 1-3, of the ... | 2000 | 11062030 |
| natural infection by simian retrovirus-6 (srv-6) in hanuman langurs (semnopithecus entellus) from two different geographical regions of india. | we have previously reported natural infection of hanuman langurs (semnopithecus entellus) from lucknow, india by a novel simian retrovirus, srv-6, a beta-retrovirus (type d retrovirus). here we describe infection by a closely related srv-6 in an isolated feral population of hanuman langurs from jodhpur in the northwestern desert region of india. serological analyses, using in-house elisa and wb, genomic amplification, and sequencing of env region (gp70 and gp20) of the viral genome were carried ... | 2003 | 12832216 |
| the endogenous langur type d retrovirus po-1-lu and its exogenous counterparts in macaque and langur monkeys. | po-1-lu, the endogenous type d retrovirus of langurs (trachypithecus obscurus) has previously been considered a progenitor to the prototype type d retrovirus, mason pfizer monkey virus (m-pmv/srv-3), that became established in macaque monkeys (macaca spp.) following a zoonosis. this study reevaluates this hypothesis to include other exogenous srvs. new sequence information from the gp70(su)-encoding region of po-1-lu shows striking similarity to the newly identified exogenous langur retrovirus, ... | 2003 | 14585330 |
| new simian beta retroviruses from rhesus monkeys (macaca mulatta) and langurs (semnopithecus entellus) from rajasthan, india. | natural infection of feral indian rhesus monkeys (macaca mulatta) by a new simian beta retrovirus, provisionally called simian retrovirus-7 (srv-7) is described. the virus is capable of in vitro replication in primary human peripheral blood lymphocytes (pbl) and b and t cell lines. we have earlier reported a novel srv, srv-6 from indian langurs (semnopithecus entellus). additional sequence analyses from gp20 transmembrane (tm) env genes of srv-6 and srv-7 place them in a separate cluster, relate ... | 2006 | 16791425 |
| development of a generic real-time pcr assay for simultaneous detection of proviral dna of simian betaretrovirus serotypes 1, 2, 3, 4 and 5 and secondary uniplex assays for specific serotype identification. | simian betaretroviruses (formerly type d retroviruses; srv) are a group of closely related retroviruses for which the natural host species are asian monkeys of the genus macaca. five serotypes have been identified by classical neutralization assays and three additional untyped variants have been reported (srv(tsukuba), srv-6, srv-7). these viruses may be significant pathogens in macaque colonies, causing a broad spectrum of clinical disease secondary to viral-induced immune suppression. undetect ... | 2009 | 19664660 |
| the structural phase transition in srv(6)o(11). | single-crystal x-ray diffraction and specific heat studies establish that strontium hexavanadium undecaoxide, srv(6)o(11), undergoes a p6(3)/mmc to inversion twinned p6(3)mc structural transition as the temperature is lowered through 322 k. the p6(3)/mmc and p6(3)mc structures have been determined at 353 k and at room temperature, respectively. for the room-temperature structure, seven of the ten unique atoms lie on special positions, and for the 353 k structure all of the seven unique atoms sit ... | 2010 | 21123877 |
