ABSTRACT
Akhtar M, Ishaq HM, Effect of
coccidiosis on immunity in day-old vaccinated Hubbard broilers, Onl J Vet Res., 29 (6): 362-368, 2025. We report effect of coccidiosis on humoral
response of day old broilers vaccinated against hydropericardium
by IHA antibody titre against HPS of the
experimentally induced coccidiosis chickens (Group A) ranged from 1:4 to 1:16 (Geaomean titre; GMT 6.95) and
that of control chickens (Group B) ranged from 1:32 to 1:512 (GMT 152.17). IHA
antibody titre against HPS of the sera samples
collected from commercial coccidiosis out break
broiler flock ranged from 1:8-1:512 (GMT 39.93). Results revealed a significant
difference (P<0.05) in GMT against HPS among experimentally infected,
control and field out break cases.
KEY WORDS:
Humoral response, hydropericardium syndrome,
coccidiosis, chickens.
