Abstract:
Two-day-old commercial chicks were inoculated orally with 2 x 10(6) oocysts of Cryptosporidium baileyi and vaccinated with 10(3.5) EID50/head of a commercially available avian infectious bronchitis (IB) live virus vaccine at 4 and 14 days following inoculation. Chicks infected with C. baileyi were shown to have an immunosuppressive effect on IB virus. It is concluded that infection with the protozoon in early life may increase their susceptibility to IB.
