Seventeen soil samples were analyzed for the presence of microflora in selected potato field soils. Seven fungal species and one bacterium species were morphologically characterized using soil dilution and streak plate methods. The predominant fungi isolated including <em>Alternaria </em>sp., <em>Aspergillus </em>sp., <em>Penicillium </em>sp., <em>Rhizopus </em>sp., <em>Bipolaris </em>sp., <em>Phytophthora </em>sp., <em>Fusarium </em>sp. and one bacterium was identified as <em>Ralstonia solanacearum</em>. Individual colonies of fungi and bacteria were counted on Potato Dextrose Agar (PDA), V8 juice Agar and their presence in soil was compared in respect of different locations of potato fields. The occurrence of <em>Phytophthora</em> sp. was medium in Tongibari and lower in Singair Union, Sonargaon, Matlab Dakshin, Gobindaganj, Palashbari, Gopinathpur and Bagmara. The highest counts of <em>R. solanacearum</em> were found in Singair Union, Tongibari and Daudkandi and the lowest counts were made in Palashbari and Bagmara. This was the first reported examination of the microbial diversity of soil microflora in some selected potato fields of Bangladesh.</p> M. A. Nitu M. Rahaman F. M. Aminuzzaman N.

Recently, hygienists have focused on the risk of transmitted diseases through currency notes. This study aims at the determination of potential pathogenic microorganisms found on the Congolese Francs currency notes circulating in Kinshasa, Democratic Republic of the Congo.</p> <p><strong>Place and Duration of the Study:</strong> This study was carried out in Kinshasa city, in the Democratic Republic of the Congo between September 3 and 29, 2019 at the Bacteriology Laboratory of the National Institute for Biomedical Research.</p> <p><strong>Methods:</strong> During this study, 36 currency notes of different denominations have been used for microbiological analysis. Currency notes were collected from vendors of the Central market and currency note dealers at Kintambo Magasin market in Kinshasa. The identification of microorganisms (bacteria and fungi) was performed using gram staining and biochemical analyses. <strong>Results:</strong> The findings reveal the presence of following microorganisms, namely <em>Bacillus</em> spp, <em>Staphylococcus aureus</em>, <em>Staphylococcus</em> spp., <em>Enterobacter</em> spp, <em>Escherichia coli</em>, <em>Serratia spp</em>, <em>Citrobacter spp, Salmonella enteritidis</em> as well as molds on the Congolese currency notes. It should be observed that circulated currency notes in Kinshasa are contaminated by bacteria and fungi. The contamination rate was based on the fact, that money is new, clean or dirty.</p> <p><strong>Conclusion:</strong> Congolese currency notes constitute the potential sources of infectious disease transmission if hygienic conditions are not respected. Molecular studies are required in order to determine the antibiotic resistance gene of these microorganisms. As the population does not know how to store these notes properly, their contamination would eventually become a major public health hazard. Therefore, a need of an awareness of the population in order to apply hygienic rules while handling currency notes. This is for the first time that such a study is being carried out in the Democratic Republic of the Congo.</p> Jeff Bekomo Iteku Donel Moswala Likabo Aaron Lelo Pambu Gédéon Ngiala Bongo Ruth Katunda Octavie Metila Lunguya Joseph Kasali Lumande ##submission.copyrightStatement## 2020-09-24 2020-09-24 16 30 10.9734/jamb/2020/v20i930278
