Tick and tick-borne diseases, especially East Coast fever, caused byTheileria parva, are amongst the most important factors limiting cattle production in Eastern, Central, and Southern Africa. In the past, they have been controlled mainly by the use of acaricides to kill ticks. Immunization has been shown to be an effective alternative method of control of tick-borne diseases in limited field trials. A development program has been initiated to produce vaccines and implement immunization on a wide scale in the region in (...) a sustainable manner as part of an integrated tick and tickborne disease control program. The consequent reduction in cattle mortality is expected to have far-reaching benefits for the region. (shrink)

Corruption is consciously taking advantage of one's special position, power or wealth for personal gain. It is spreading because there is ignorance and absence of adequate knowledge on the subject and how to correct and control it. Added to this is the innocence of the believers in the infallibility of the legal, political, bureau cratic and other social systems. They become the victims of the exploiters of the system who know the system weaknesses and how to take advantage of it (...) for their personal gain. There are two levels of corruption—the grand corruption of those in power and the petty corruption of the lower levels. Corruption is a malady affecting both affluent and poor nations. while affluent nations do not exhibit much evidence of petty cor ruption, poor nations are subject to the effects of both grand and petty corruption from within their own bor ders and the effects of the grand corruption by the affluent. Social systems, value education, spiritual leam ing and character building are necessary to eradicate this cancer. (shrink)
