Antigenic response of midgut, Boophilus microplus, cell culture vaccine was
evaluated. The antibody titres against the gut-membrane (GM) and gut-solub
le (GS) antigens were measured by indirect hemagglutination test. The antib
ody response against GM antigen was significantly higher (p < 0.01) than th
at of GS antigen. It was assumed on the basis of antibody titres against GM
and GS antigens that the in vitro propagated midgut cells, Boophilus micro
plus, contained substantial membrane and membrane associated immunogenic co
mponents. (C) 1999 Elsevier Science B.V. All rights reserved.
