Infection of livestock with African trypanosomes leads to haematological changes such as anaemia and pancytopenia and to immune defects, including suppression of T-cell responsiveness and an excessive increase in the CD5+ B-cell population in blood and spleen. It has been shown that certain breed...

Development of bovine-specific cytokine reagents at ILRAD
Interleukin-3(IL-3) is one of the cytokines that act during the early and late stages of blood cell formation. To enable the study of the role of IL-3 in bovine haemopoietic stem cell differentiation, the polymerase chain reaction was used to amplify an IL-3 cDNA from first-strand cDNAs prepared ...
Dendritic cells (DC) constitute the most effective immune cell population for priming and recalling T cell responses to foreign antigens. DC patrol the peripheral tissues collecting foreign antigen for subsequent presentation by classical class II MHC molecules to T cells in the draining lymph no...

A lambda gtll cDNA library was constructed using mRNA isolated from Theileria parva-infected bovine lymphocytes. Sequencing of random clones of this library resulted in the identification of a cDNA encoding bovine interleukin-16 (IL-16). The cDNA has an open reading frame of 1134 bp, and a 3? unt...

The nucleotide (nt) sequence encoding the bovine homologue of interleukin-5 (boIL-5) was determined. Total cDNA generated from stimulated bovine peripheral blood lymphocytes was used to amplify the boIL-5 gene using primers based on the 5' and 3' untranslated regions of the ovine IL-5 cDNA sequen...

The rate of forest cover loss in the humid tropics of Cameroon is one of the highest in Central Africa. The aim of the large-scale, two-year research project described here was to understand the effect of the country's economic crisis and policy change on small-scale agricultural systems and land...

The Amazon is the largest tropical forest area on Earth, and is undergoing rapid deforestation since the last four decades. These conversions are mostly located in frontier areas distributed along the so-called “arc of deforestation”. Within this large zone, various land use change processes are ...

Contrasted land use and development trajectories in the Brazilian Amazon
The department of Santa Cruz in Bolivia makes part of the Amazon basin, and it embraces a large portion of the Bolivian lowland forest, with most of its area covered by semideciduous forest. The agricultural development, and hence deforestation in Santa Cruz, does not follow any similar path of o...

This paper analyzes geo-referenced data to elucidate the relations between deforestation and access to roads and markets, attributes of the physical environment, land tenure, and zoning policies in Santa Cruz, Bolivia. It presents separate models for Santa Cruz as a whole and for seven different ...
