Abstract_ Background This study aimed at investigating a potential effect caused by coccidia on the immune response to vaccine- and very virulent infectious bursal disase virus vvIBDV in SPF chickens. Methods Two groups of three weeks old SPF chickens were vaccinated prior to inoculation with coccidia and challenge with virulent IBDV all within a period of eight days. Two control groups were similarly treated except that challenge with field virus was omitted in one group while inoculation with coccidia was omitted in the other group. Clinical signs lesions in the intestines caused by coccidia lesions in the bursa of Fabricius caused by IBDV IBDV-antibody titres and virus detection by reverse transcription polymerase chain reaction RT-PCR were compared .
