Genetic diversity studies that utilize phenotypic and genetic information are informative when formulating breeding and conservation plans. The present study utilizes sequences of mitochondrial DNA (mtDNA) D-loop region of 232 village chickens from Southern and Northern Nigeria to determine the o...

To map the genetic sources of trypanotolerance in mice, a linkage analysis of survival following trypanosome challenge was performed by selective genotyping in a large F2 population produced by crossing the resistant C57BL/6 and susceptible BALB/c inbred mouse lines. We report evidence of a chrom...

This study aimed to characterize the local chickens and their production systems and to investigate the opportunities for improvement. The study was carried out in 18 villages in northern Jordan with the participation of 120 households. Data were collected by individual interviews and surveys sup...

Cattle immunised with a recombinant form of p67, the major surface antigen of Theilleria parva sporozoites, have been shown to be protected against parasite challenge. In an attempt to simplify the immunisation procedure live attenuated Salmonella strains expressing p67 have been constructed and ...

A bioassay was used to measure erythropoietin (EPO) concentrations in calves with haemorrhagic anaemia due to blood loss and in calves with anaemia due to Trypanosoma congolense infection. The bioactivity of EPO was measured in the assay by its stimulatory effect on 125I-deoxyuridine incorporatio...

Nuclear extrachromosomal DNA elements have been identified in several kinetoplastids such as Leishmania and Trypanosoma cruzi, but never in Trypanosoma brucei. They can occur naturally or arise spontaneously as the result of sublethal drug exposure of parasites. In most cases, they are represente...

The growing risk of vulnerability to climate change is widely discussed in the scientific and political sphere. More evidence from local case studies emerges that document this risk. Vulnerability to climate change and variability appears most likely to negatively affect poor people, particularly...

Miombo woodlands cover vast areas of southern Africa. Of comparatively little interest for export-oriented commercial logging, they are part of a complex system of rural land use that integrates woodland management with crops and livestock. There is also evidence that woodland resources are exten...
