The purpose of this chapter is to describe preliminary results in the attempt to model the linkages between property rights, risk, and livestock development in Niger. Rainfall variation is often identified as the major environmental risk faced by agropastoralists (for example, Swallow 1994). Among the many riskmanagement strategies that are identified, livestock mobility is seen as one of the m...

Representatives of the genus Aspergillus are opportunistic fungal pathogens. Their conidia can reach the alveoli by inhalation and can give rise to infections in immunocompromised individuals. Aspergillus fumigatus is the causal agent of invasive aspergillosis in nearly 90% of the cases. It is not yet well-established what makes this fungus more pathogenic than other aspergilli such as A. niger...

This research was conducted in order to investigate the effect of chemical and biological processing on the chemical composition, gas production parameters and in vitro digestibility of Cicer arietinum wastes in a completely randomized design (7 treatments and 3 replicates). Treatments were: unprocessed Cicer arietinum wastes (control) and processed with water (2.5 liter/kg DM), sodium hydroxid...

BACKGROUND Aspergillus terreus is a natural producer of itaconic acid and is currently used to produce itaconic acid on an industrial scale. The metabolic process for itaconic acid biosynthesis is very similar to the production of citric acid in Aspergillus niger. However, a key enzyme in A. niger, cis-aconitate decarboxylase, is missing. The introduction of the A. terreus cadA gene in A. niger...

BACKGROUND Aspergillus niger is widely used for enzyme production and achievement of high enzyme production depends on the comprehensive understanding of cell's metabolic regulation mechanisms. RESULTS In this paper, we investigate the metabolic differences and regulation mechanisms between a high glucoamylase-producing strain A. niger DS03043 and its wild-type parent strain A. niger CBS513.8...

Wild type Aspergillus niger isolates from different biotopes from all over the world were compared to each other and to the type strains of other black Aspergillus species with respect to growth and extracellular enzyme profiles. The origin of the A. niger isolate did not result in differences in growth profile with respect to monomeric or polymeric carbon sources. Differences were observed in ...

This work aimed to identify the species distribution of common clinical and environmental isolates of black Aspergilli based on simple restriction fragment length polymorphism (RFLP) analysis of the β-tubulin gene. A total of 149 clinical and environmental strains of black Aspergilli were collected and subjected to preliminary morphological examination. Total genomic DNAs were extracted, and PC...

Background: In Niger, palliative care is a necessity in everyday medical practice. However, the setting up of structures and / or mobile teams specifically dedicated to palliative medicine still faces enormous challenges Methods: This work is an update on the status of research, teaching and services relating of palliative medicine in Sakoira Integrated Health Center (SIHC) in Niger and literat...
