Modelling the transmission dynamics of Theileria annulata : model structure and validation for the Turkish context [PDF]

, 2012
A mathematical model that describes the transmission dynamics of Theileria annulata is proposed that consists of 2 host components: the Hyalomma tick population and a compartmental model of T. annulata infection in the cattle population.
