Aims: The study aims to identifying the microorganisms associated with post-harvest rot of frafra potatoes in Bongo-soe, Upper east region of Ghana. Place and Duration of Study: Department of Horticulture and the Pathology laboratory of the Faculty of Agriculture, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. The Solenostemon rotundifolius tubers were stored at the Horticulture Department laboratory whiles rot identification was carried out at the Pathology laboratory of the Faculty of Agriculture. The Tubers were stored from 2nd November, 2012 to 22nd March 2013. Methodology: Four hundred (400) tubers of black cultivar and four hundred (400) tubers of a brown cultivar of Solenostemon rotundifolius tubers showing visible signs of rot during the storage were collected. Pieces of diseased tissues from the margin of the necrotic collected and immersed in 10% commercial bleach solution for sterilisation, for one minute. These were then blotted dry and plated on Potato Dextrose Agar PDA. The plates were sealed with a cellotape until growth occurred. Results: The microorganisms identified to be responsible for causing rot in Solenostemon rotundifolius tubers were six in number. Colletotrichum gloeosporioides was identified to be responsible for 30.76% of rots observed, followed by Aspergillus niger, 23.07%, Curvularia lunata, 19.23%, Aspergillus flavus, 11.54%, Trichoderma sp and Penicillium sp both recorded 7.70% of rots observed. The percentage incidence of Aspergillus niger (15.38%), Curvularia lunata (11.54%) and Aspergillus flavus (7.69%) was higher in the black cultivar as compared with the brown cultivar which had percentage incidence of 7.69%, 7.69% and 3.85% respectively. Also, the percentage incidence of Colletotrichum gloeosporioides (15.38%) and Penicillium sp (3.85%) was the same in both the black and brown cultivars of Solenostemon rotundifolius tubers used in this study. Conclusion: The activities of the damaging microorganisms can be reduced by controlling mechanical injury during harvesting, transportation and storage of Solenostemon rotundifolius tubers should be prevented or reduced because they pave the way for tuber infection by the rot causing microorganisms.

Background: Human rabies, often contracted through dog bites, is a serious but neglected public health problem in the tropics, including Ghana. Due to its high fatality rate, adequate knowledge and vaccination of domestic dogs against the disease are very crucial in reducing its burden. We examined dog owners’ knowledge level on rabies and factors that influenced anti-rabies vaccination of dogs in the Upper East Region of Ghana. Methods: This descriptive cross-sectional study was conducted among 260 randomly sampled dog owners in six communities from six Districts using a multistage sampling technique, in the Upper East Region of Ghana. An interviewer-administered questionnaire was used to collect data from the respondents. Descriptive and inferential analyses were done using STATA 14.1. Results: While knowledge about rabies was 199 (76.5%), that about anti-rabies vaccination was 137 (52.7%). District of residence (χ2 = 112.59, p < 0.001), sex (χ2 = 6.14, p = 0.013), education (χ2 = 20.45, p < 0.001) as well as occupation (χ2 = 11.97, p = 0.007) were significantly associated with rabies knowledge. District of residence (χ2 = 57.61, p < 0.001), Educational level (χ2 = 15.37, p = 0.004), occupation (χ2 = 11.66, p = 0.009), religion (χ2 = 8.25, p = 0.016) and knowledge on rabies (χ2 = 42.13, p < 0.001) were also statistically associated with dog vaccination against rabies. Dog owners with good knowledge on rabies for instance, were more likely to vaccinate their dogs against rabies compared to those with poor knowledge [AOR = 1.99 (95% CI: 0.68, 5.86), p = 0.210]. Dog owners with tertiary level of education were also 76.31 times more likely (95% CI: 6.20, 938.49, p = 0.001) to have good knowledge about rabies compared to those with no formal education. Conclusions: Dog owners in the Upper East Region of Ghana had good knowledge about rabies. This, however, did not translate into correspondingly high levels of dog vaccination against the disease. Rabies awareness and vaccination campaigns should, therefore, be intensified in the region, especially among the least educated and female dog owners.

The intertwining nature of African life and livelihood is a considerable challenge to the discourse of development. In as much as the view on unlocking both the spiritual and physical dimensions of life in developmental endeavours is frowned upon, contemporary exploration into indigenous knowledge systems as an alternative discourse of development does not simply transform the dialogue but posits it as a discourse of power. This article examines the interplay between indigenous beliefs and knowledge systems and the discourse of development, with a focus on the Nankani in the Upper East Region of Ghana.
