However, the persistence of the IgG response prevents it being of value for several months in areas where triatomine control programmes have been implemented. In this investigation, IgM-antibody reactions to crude salivary antigens or rTiSP14.6 decayed rapidly after exposure of chickens and were measurable for only 18 days after a single challenge with T. infestans. In serial exposure experiments, chickens from low and high exposure groups showed no significant differences in anti-saliva and anti-rTiSP14.6 IgM-antibody titres. Highly immunogenic salivary antigens of 12 and 14 kDa were recognised by all chicken sera.
