Towards Establishing Capacity for Biological Dosimetry at Ghana Atomic Energy Commission.

The aim of this study was not only to obtain basic technical prerequisites for the establishment of capacity of biological dosimetry at the Ghana Atomic Energy Commission (GAEC) but also to stimulate interest in biological dosimetry research in Ghana and Sub-Saharan Africa. Peripheral blood from four healthy donors was exposed to different doses (0-6 Gy) of gamma rays from a radiotherapy machine and lymphocytes were subsequently stimulated, cultured, and processed according to standard protocols for 48-50 h. Processed cells were analyzed for the frequencies of dicentric and centric ring chromosomes.

Preliminary investigation of bovine tuberculosis in suspected beef from a metropolitan abattoir in Ghana with Ziehl-Neelsen microscopy.

Bovine tuberculosis is an important zoonotic disease transmissible through aerosols inhalation and the ingestion of contaminated milk and meat from cattle. Abattoirs in Ghana mainly depend on post-mortem examinations as means of diagnosing the presence of mycobacterium in meat (beef). A Ziehl-Neelsen microscopy was used to investigate the presence of Mycobacterium bovis as Acid-Fast Bacilli (AFBs) in beef samples from the Kumasi Metropolitan abattoir; thereby vetting post-mortem examinations at the abattoir.
