Distribution and occurrence of indigenous strains of atoxigenic and toxigenic Aspergillus section Flavi in groundnut producing areas of Southern Tanzania
The objective of this study was to isolate and identify atoxigenic and toxigenic strains of Aspergillus section Flavi in southern Tanzania, and investigate possible application of atoxigenic strains in control of aflatoxin levels in groundnuts. Fungal communities in soils from groundnut fields were examined to see the distributions of aflatoxin-producing Aspergillus species and to spot […]
Genetic diversity of local chicken ecotypes in selected part of central tanzania
This study was carried out to evaluate the genetic diversity of Central Tanzanian indigenous chicken. Chickens were collected from six different districts of Central part in Tanzania (Dodoma, Kondoa, Singida, Manyoni, Igunga and Tabora). Eighteen microsatellite markers recommended by International Society for Animal Genetics, Food and Agriculture Organization advisory group on animal genetic diversity were […]
