Populasi Ascaridia galli Dalam Usus Halus Ayam Yang Diberikan Kombinasi Ekskretori/Sekretori L3 dan Imunoglobulin Yolk
ABSTRACT: The purpose of the
present study was to determine the presence of worm populations in intestine of
chickens vaccinated and combined with egg yolk to experimental Ascaridia galli
infection. Amount of 18 head chickens were devided into six groups (A – F).
Group A, the chickens were not vaccinated. Group B, the chickens were
vaccinated with excretory/secretory of A. galli L3. Group C, the chickens were
vaccinated with excretory/secretory of A. galli L3, challenged with dose 1000
L2, and treated ten times with 0,875 mg egg yolk with an interval of one day
intra orally. Group D, the chickens were vaccinated with excretory/secretory of
A. galli L3 and challenged with dose 1000 L2. Group E, the chickens were
challenged with dose 1000 L2 and treated ten times with 0,875 mg egg yolk with
an interval of one day intra orally. Group E, the chickens were challenged with
dose 1000 L2. Intestinal worm burdens of infected groups were recorded. The result
showed that excretory/secretory of A. galli L3 combined with egg yolk decreased
significantly A. galli survival in intestine of laying hens. Vaccinations were
positively correlated with worm burden at 12 weeks after chalanged. The results
suggest that A. galli L3 excretory/secretory product contain potential antigen
and that antibody-mediated mechanisms contribute to immune protection.
