Study on seasonal activity in dogs and ehrlichial infection in Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) from southern Uruguay

The seasonal activity on dogs of Rhipicephalus sanguineus in southern Uruguay has been studied from samples collected in veterinary clinics of the country. From a total of 744 specimens, adults (92%) were active on dogs between August and March (peaking in October) being absent between April and Jul...
