| association of intraspecific wounding with hantaviral infection in wild rats (rattus norvegicus). | the potential for hantaviral transmission among wild norway rats by wounding associated with aggressive interactions was evaluated using a prospective sero-epidemiological study coupled with a mark-release-recapture survey. there was a significant association between an animal's serological status and the presence of wounds. longitudinal studies of marked and released animals showed seroconversion between captures was associated with wounding between captures more often (33%) than expected by ch ... | 1988 | 3141203 |
| expression of the hantaan virus m genome segment by using a vaccinia virus recombinant. | a cdna containing the complete open reading frame of the hantaan virus (htn) m genome segment has been cloned into vaccinia virus. this recombinant virus expresses two glycoproteins which are similar to the htn structural glycoproteins, g1 and g2, in molecular weight, cleavage pattern, and cellular distribution. both htn and recombinant vaccinia virus glycoproteins are exclusively associated with the golgi apparatus of the cell. despite this intracellular restriction, mice inoculated with the re ... | 1988 | 3123711 |
| baculovirus expression of the small genome segment of hantaan virus and potential use of the expressed nucleocapsid protein as a diagnostic antigen. | autographa californica nuclear polyhedrosis virus (acnpv) was used as an expression vector for the nucleocapsid protein gene of hantaan virus. two different cdna clones representing the small genome segment of hantaan virus were inserted into the transfer vector pacym1, and recombinants were generated by replacement of a portion of the baculovirus polyhedrin gene with the foreign, hantaan virus gene. recombinants containing both the first and second atg initiation codons of the hantaan virus gen ... | 1988 | 2895799 |
