arbovirus isolations from mosquitoes collected during 1988 in the senegal river basin.during august and september 1988, we collected adult mosquitoes from 14 locations in the senegal river basin to search for evidence of rift valley fever (rvf) viral activity one year after the 1987 outbreak, which occurred along the senegal-mauritania border. more than 62,000 specimens representing 18 species in seven genera were collected with carbon dioxide-baited, solid-state army miniature light traps and sheep-baited traps. twenty virus isolations from culex, aedes, and anopheles mosquitoes ...19921361722
changes in rift valley fever neutralizing antibody prevalence among small domestic ruminants following the 1987 outbreak in the senegal river basin.following the rift valley fever (rvf) epizootic of 1987 in the senegal river basin, 2 series of serosurveys were carried out. in 1988 and 1989, respectively, 303 and 331 randomly selected sheep and goats were investigated and sera tested for the presence of specific rvf-virus-neutralizing antibodies. in 1988, 24.4% of the sera was found to have anti-rvf neutralizing antibodies and in 1989, 19.3% was found. in 1988, we observed in the dagana district, including the 1987 epizootic area, a signific ...19912052753
