Eight black-backed jackals and seven side-striped jackals were given SAD (Berne) rabies vaccine by direct oral instillation. Three different vaccine doses were used: 106.3, 106.8 and 107.5 median tissue culture infectious doses. Two additional jackals were given vaccine in chicken heads. One grou...

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...

The authors evaluate the impact of foot and mouth disease (FMD) and control of the disease in the Philippines using cost-benefit analysis. A scenario in which FMD control is maintained at recent levels with continued presence of the disease is compared to scenarios in which a publicly funded prog...

A pilot study of the economic impact of foot and mouth disease (FMD) in the countries and region of South-East Asia is described. Previous economic impact assessments are reviewed and summarised and a synthesis of these contributions is constructed. A framework for the future economic impact of t...

The impact of tick control on the productivity of indigenous cattle was investigated in three herds of East African shorthorn Zebu and Zebu×Ankole (Nganda) breeds, maintained under three tick management systems practised under ranch conditions: twice-a-week dipping, once-a-month dipping, and no t...

Compulsory short-interval dipping of cattle for tick control has been enforced in Zimbabwe since the early part of this century. Intensive dipping was initially introduced as a measure to control East Coast fever (ECF), following its introduction from eastern Africa. Dipping was subsequently foun...

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 ...

This paper reviews the past contributions of epidemiology and economics to the control of tick-borne infections of cattle in Africa. The factors affecting successful and unsuccessful control are evaluated on a gographical and on a production systems basis, with particular reference to Theileria p...

In a world of ever-increasing competition for resources, human, economic and environmental, it is now more important than ever before that a thorough understanding is acquired of the effect of large-scale interventions to relieve constraints to livestock production, such as disease control progra...
