Specific pathogen-free chicken flocks may carry antibodies to chicken anaemia agent, avian nephritis virus, and group A rotavirus, highlighting the need for their elimination.
McNulty et al. (1989) conducted a cross-sectional in Infection with chicken anaemia agent, avian nephritis virus, and group A rotavirus. Antibodies to chicken anaemia agent, avian nephritis virus and group A rotavirus was evaluated on Presence of antibodies to chicken anaemia agent, avian nephritis virus and group A rotavirus. A survey of specific pathogen-free chicken flocks revealed that while some were free of infection, others showed evidence of infection with chicken anaemia agent, avian nephritis virus, or rotavirus.
