A review is presented on disease development in bean var. mixtures and in pure stands, the effect on diseases of adding resistance components to susceptible mixtures, and the potential on nongenetic methods to control diseases in mixtures. Four mechanisms seem to reduce disease incidence in var. ...

Heartwater is a severe tick-borne, non-contagious disease of ruminant livestock caused by the rickettsia Cowdria ruminantium, which is endemic in much of sub-Saharan Africa and in the Caribbean. Transmission occurs via ticks of the Amblyomma genus, primarily A. variegatum and A. hebraeum. Intense...

The general role of veterinary epidemiology and economics to national animal-disease control throughout the world is considered for the four main groupings of animal diseases: zoonotic, food-borne, endemic and epidemic diseases. This is done by considering how veterinary epidemiology and economic...

This paper outlines four key pillars of epidemiology and economics in national animal disease control; prioritizing in animal disease control; the comparative advantage of Ethiopia in the leather industry; and gives some impressive figures including estimated production of hides and skins, employ...

Background: Rift Valley Fever (RVF) is a mosquito-borne viral zoonosis that was first isolated and characterized in 1931 in Kenya. RVF outbreaks have resulted in significant losses through human illness and deaths, high livestock abortions and deaths. This report provides an overview on epidemiol...

Pastoral cattle live in highly structured communities characterized by complex contact patterns. The present paper describes a spatially heterogeneous model for the transmission of contagious bovine pleuropneumonia (CBPP) developed specifically for pastoral communities of East Africa. The model i...

The development of a stochastic, state-transition model of rinderpest transmission dynamics is described using parameter estimates obtained from both laboratory and participatory research. Using serological data, the basic reproduction numbers for lineage-1 rinderpest virus in southern Sudan and ...

Brucellosis is an important disease among livestock and people in sub-Saharan Africa. In general, the incidence is the highest in pastoral production systems and decreases as herd size and size of landholding decreases. The prevalence of risk factors for infections are best understood for bovine ...
