Although the effects of chicken anaemia virus (CAV) infection have frequently been investigated in young chickens, there have been few studies of the pathogenesis of CAV infection in older birds. The aim of the work reported here was to study viral loads in 6-week-old chickens and to compare these with those seen in younger birds. Specific pathogen free chickens were inoculated at 1 day or at 6 weeks of age with 10(4) median tissue culture infective doses of CAV by the intraocular route. Chicks infected when 1 day old were euthanized at day 14, 18 or 22 post inoculation (p.i.), and those infected when 6 weeks old at day 16, 18 or 20 p.i. Their body and thymus weights were determined and samp..
