Young, A.S.Ochanda, H.Perry, Brian D.Morzaria, S.P.Dolan, T.T.Medley, G.F.Gettinby, G.[The biology of the transmission dynamics of Theileria parva]The biology of the transmission dynamics of Theileria parva

A mathematical description of the transmission dynamics of the tick-borne infection Cowdria ruminantium in commercial beef enterprises in Zimbabwe was used to consider the potential impact of a candidate vaccine to prevent heartwater. The important characteristics of the vaccine were (1) a delay ...


O'Callaghan, C.J.Medley, G.F.Peter, T.F.Mahan, S.M.Perry, Brian D.[Predicting the effect of vaccination on the transmission dynamics of heartwater (Cowdria ruminantium infection)]Predicting the effect of vaccination on the transmission dynamics of heartwater (Cowdria ruminantium infection)

Adult Amblyomma hebraeum ticks, the principle vector of heartwater (cowdriosis) of domestic ruminants in southern Africa, were collected in pheromone traps placed in Kruger National Park, an exclusively wildlife sanctuary in South Africa. These ticks transmitted Cowdria ruminantium, the rickettsi...


Peter, T.F.Bryson, N.R.Perry, Brian D.O'Callaghan, C.J.Medley, G.F.Smith, G.E.Mlambo, G.Horak, I.G.Burridge, M.J.Mahan, S.M.[Cowdria ruminantium infection in ticks in the Kruger National Park]Cowdria ruminantium infection in ticks in the Kruger National Park

The transmission of Theileria parva by nymphal and adult Rhipicephalus appendiculatus was compared by the assessment of salivary gland infections in tick batches fed on the same group of infected cattle at the same time. When larval and nymphal R. appendiculatus Muguga ticks were fed concurrently...


Ochanda, H.Young, A.S.Wells, C.Medley, G.F.Perry, Brian D.[Comparison of the transmission of Theileria parva between different instars of Rhipicephalus appendiculatus]Comparison of the transmission of Theileria parva between different instars of Rhipicephalus appendiculatus
