Between 1986 and 1989, 2,255 sera collected from six domestic animal species in Nigeria were tested for antibodies to Rift Valley fever (RVF) virus. In addition, a longitudinal study was carried out from July 1987 to December 1988, using ten sentinel flocks on four farms at Ibadan and Ile-Ife, to determine the activity of RVF virus (RVFV). All samples were(More)
Between 1985 and 1989, a total of 3,121 human sera collected from different population groups in six ecological zones of Nigeria were tested for the presence of antibodies to Rift Valley fever (RVF) virus by the haemagglutination-inhibition test. All reactive sera were further tested by the plaque reduction neutralisation test and specific RVF(More)
Experimental infection of three indigenous breeds of sheep in Nigeria, namely the West African Dwarf (WAD), Yankasa and Ouda resulted in fatal disease with the Zinga Rift Valley Fever virus. Infected sheep of the three breeds responded by pyrexia within 24 h of infection, that lasted 6 to 7 days, but peaked between day 2 and 4 post-infection. Viraemia(More)
A male patient, aged 31 years, with a cytomegalovirus (CMV) myocarditis is described, who showed a high IgM antibody titer for cytomegalovirus infection of 1:1,024 and a rise of the titer for complement-fixing antibody from 1:< 16 to 1:256. CMV could be isolated from the urine. Investigations for other etiological factors were negative, and we assumed a(More)
The five synthetic antigenic sites of sperm whale myoglobin were used in their free form (i.e. not coupled to any carrier) to immunize separate groups of BALB/cByJ mice. The synthetic peptides corresponded to: site 1, residues 15-22; site 2, residues 56-62; site 3, residues 94-99; site 4, residues 113-119; site 5, residues 145-151. Serum samples obtained(More)
Two synthetic peptides corresponding to surface regions of sperm whale myoglobin that are not antigenic in the native molecule were used in their free form (i.e. not coupled to a carrier) to immunize separate groups of Balb/cByJ mice. The synthetic peptides corresponded to regions 1-6 and 121-127. Serum samples obtained from each group of mice contained(More)
