title: Experimental production of tick pyaemia.
abstract: Lambs aged 2 weeks were inoculated with a tick-borne fever (TBF) stabilate on Day 0 and Staphylococcus aureus-contaminated ticks were applied on Day 5. Tick pyaemia was produced experimentally for the first time using Ixodes ricinus as a mechanical vector of S. aureus. Lambs aged 18 weeks were rechallenged with a homologous strain of TBF, and S. aureus-infected ticks applied 5 days later. No significant changes were noted at post-mortem examination.
