Antibody response of dogs inoculated with a large number of cultured canine monocytes adsorbed with a calicivirus in advance.
Five conventional Beagle dogs were intravenously injected with ten million canine monocyte cells (Cn/K99) cultured in vitro (Kadoi, 2000) adsorbed with a strain of calicivirus originally isolated from lions (Kadoi et al., 1997). Another two Beagle dogs were injected similarly with the virus suspension solely as control. Serum samples were collected from these dogs at intervals and specific seroneutralizing antibody production against the virus was measured in vitro. A significantly higher antibody production was demonstrated in the five dogs group. A clear booster effect was also proved in the sera of the dogs after the second virus inoculation made on day 100. A possibility of antigen presentation function of non-self monocytes is suggested.
