Abstract:
The time-course for the development of infectivity was studied in Hyalomma detritum ticks fed as pre-imagoes on calves infected with Theileria annulata. Unfed adults derived from infected nymphs were noninfectious when inoculated into susceptible calves, whereas ticks of both sexes that had fed for 2–3 days or longer on calves or rabbits were always infectious. Some adults fed for only 1–2 days were infectious, whereas others were not. As few as 2 ticks were capable of infecting susceptible calves. © 1978, Cambridge University Press. All rights reserved.
