Journal Article 1999

Autor: O'Callaghan, C.J. Medley, G.F. Peter, T.F. Mahan, S.M. Perry, Brian D.

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 ...

Heartwater, caused by the rickettsial organism Cowdria ruminantium, is a serious constraint to livestock development in much of sub-Saharan Africa. Traditionally, the disease has been controlled by the use of chemical acaricides to control the vector tick. The University of Florida/USAID-supporte...

Journal Article 1998

Autor: Perry, Brian D. Chamboko, Tafireyi Mahan, S.M. Medley, G.F. Minjauw, B. O'Callaghan, C.J. Peter, T.F.

The authors highlight the reliance on repeated natural infections by tickborne pathogens to maintain immunity in immunized herds. That incidence of clinical heartwater in cattle, caused by Cowdria ruminantium, is low while intensive acaricide use interrupts transmission of pathogens. Evidence is ...

Immune mechanisms against Cowdria ruminantium infection in livestock hosts are being investigated. This knowledge will be important for identification of protective antigens of C. ruminantium which will have application in the Development of vaccines against heartwater. T-cell Con-A supernatants ...

Heartwater is a tick-borne disease of cattle, sheep and goats and some wild ruminants prevalent in much of Africa and the Caribbean. It is caused by the rickettsial organism Cowdria ruminantium and transmitted by ticks of the genus Amblyomma. The disease has traditionally been controlled by the u...
