Epidemiology and control of trypanosomosis.

Tsetse-transmitted trypanosomosis remains a major constraint to the development of agriculture, particularly to that of livestock production in sub-Saharan Africa. It is estimated that 10 million km2 of Africa are tsetse infested, exposing some 50 million people and 60 million cattle to the risk of trypanosomosis. The epidemiology of the disease is complex and is greatly influenced by management and farming practices. The different control strategies are reviewed and their comparative advantages assessed. It is concluded that eradication of tsetse flies, while desirable, is rarely achieved. It is perhaps more realistic to aim for disease suppression, with vector-control campaigns linked to sustainable land-use programmes. Nevertheless, progressive tsetse eradication remains the long-term goal.

Comparison of modified immunodiffusion and Bacteriological Analytical Manual (BAM) methods for detection of Salmonella in raw flesh and highly contaminated food types.

A wide variety of naturally contaminated and inoculated raw flesh and highly contaminated food types was analyzed by a modified immunodiffusion enrichment protocol and the Bacteriological Analytical Manual (BAM) method to determine the equivalence of these methods. This modification was developed by Agriculture Canada to allow addition of a high-temperature selective enrichment step in tetrathionate brilliant green broth at 42 degrees C while maintaining a 2-day total test time. Foods representing red meat, white meat, frog, and seafoods and one type of animal meal were evaluated. A total of 320 samples was tested, resulting in false negative rates of 5.2 and 3.5%, respectively, for the modified immunodiffusion and the BAM culture methods. The overall agreement rate was 96.9%.

Nature's medicinal bounty: don't throw it away.

Plant-derived drugs have an important place in both traditional and modern medicine. For this reason a special effort to maintain the great diversity of plant species would undoubtedly help to alleviate human suffering in the long term. Proven agroindustrial technologies should be applied to the cultivation and processing of medicinal plants and the manufacture of herbal medicines.

Water: where from, and for whom?

When the agricultural sector takes measures to diminish water losses, access to water for domestic purposes may be greatly reduced and community health may be adversely affected.
