[experience with antirabies vaccination of foxes using the oral route coordinated among several european countries and perspectives on the use of recombinant vaccinia-rabies virus].	campaigns of fox vaccination against rabies were carried out in belgium, grand-duchy of luxembourg and france in september 1986, june and september 1987. the sad b19 attenuated strain of rabies virus, contained in baits (tübingen baits) was used as vaccine. baits were distributed at a range density of 11 to 15 baits per km2. first results are very encouraging. a recombinant vaccinia virus harbouring the rabies virus glycoprotein gene has been developed. this recombinant virus can be given to the ...	1988	3268767
[health ethology of the fox and antirabies vaccine in the italian experience].	in order to contribute to the planning of antirabies oral vaccination of foxes a series of ethological and ecological investigations have been carried out. the results obtained are briefly summarized and discussed together with experimental data on antirabies immunization of dogs and foxes with different vaccines.	1988	3268766
present status of bat-rabies in europe.	since 1985 there has been an increase of bat rabies in europe, especially in denmark, the federal republic of germany and the netherlands. the present knowledge on the epidemiology, diagnosis and prophylaxis of the disease is summarized.	1988	3268764

ecology and epidemiology of raccoon rabies.	two areas of the united states presently are experiencing epizootics of raccoon rabies, which have been followed by the development of an enzootic state. these include four southeastern and five mid-atlantic states. information was obtained from 1,610 raccoons submitted for rabies testing in four of the affected mid-atlantic states during 1982 and 1983 and from 798 raccoons from virginia during 1984 and 1985. analysis of the two sets of data provided an opportunity to characterize certain aspect ...	1988	3264616
interleukin 2 increases protection against experimental rabies.	vaccination with either whole inactivated rabies virus or immunosome (rabies glycoprotein anchored on liposomes) induces a high level of interleukin 2 (il 2) production after in vitro specific stimulation of splenocytes from primed mice (9). on the contrary, infection with a live rabies virus does not specifically induce the production of il 2: splenocytes from ill mice previously infected with wild rabies virus cannot be specifically stimulated by rabies antigens, whereas they can be non-specif ...	1988	3261273
enhancement of antigen-specific interleukin 2 production by adding liposomes to rabies antigens for priming.	antigen-specific il-2 production was assessed, using splenocytes from rabies immune mice incubated for 24 h with rabies virus antigen. the antigenic material used for in vivo priming was either purified glycoprotein from rabies virus, or the inactivated virus. the time between priming, harvesting and restimulation of the splenocytes was 7 days. it was found that when antigenically inert liposomes were injected, together with antigenic material, to the prospective splenocyte donor mice, il-2 prod ...	1988	3259943

efficacy of rabies vaccines against duvenhage virus isolated from european house bats (eptesicus serotinus), classic rabies and rabies-related viruses.	isolates of rabies from separate enzootics can be distinguished by their reactions with panels of monoclonal antibodies (mabs) directed to different sites on the nucleocapsid and glycoproteins of the virus. estimates of antigenic relatedness can be made by comparing similarities among groups. in this manner it can be shown that while classic strains of rabies react with most of the mabs, the rabies related lyssaviruses (mokola, lagos and duvenhage) react with only a few of the mabs and isolates ...	1988	3245296
improved antigenicity of the hiv env protein by cleavage site removal.	the hiv env glycoprotein mediates virus infection and cell fusion through an interaction with the cd4 molecule present at the surface of t4+ lymphocytes. although env presents a major antigenic target, vaccinia recombinants expressing env elicit low titres of anti-env antibody (kieny et al., bio/technology, 4, 790-795, 1986). to delimit the functional domains of env and to improve the immunogenicity of the vaccinia recombinants we constructed variants expressing env proteins in which the site pe ...	1988	3237686
