Abstract
Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector's saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. We used ELISA to quantify the antibody levels in the sera and exposed chicken eggs. High IgY levels were observed following immunization; furthermore, higher reactivity was observed in the eggs and species-specific immune response was observed post final immunization. Chicken eggs can be used as sentinels to surveil vector saliva antibodies.

This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis
This study assessed the viability of using eggs as a tool to monitor exposure to leishmaniases and malaria vectors by detecting IgY antibodies in the eggs of chickens exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis
Summary
Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector’s saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. Antibodies developed against the hematophagous arthropods saliva were used as exposure markers for different vector species.
