Coronavirus disease 2019 (COVID-19) pandemic: What is the level of knowledge, attitude, and practice in Kandahar, Afghanistan?
There is a rising concern for the rapid increase of COVID-19 confirmed cases in Kandahar province. From zero reported cases until 17th March 2020, then Kandahar saw a sudden rise in the cases by 16th May 2020. Decreased literacy rates, poor health education, lack of facilities, inconsistent government policies, and defying coronavirus safety advisory by the public have resulted in the rapid spread of COVID-19. The...

Bacterial community composition and diversity along the southern coastlines of the Atlantic Ocean in Cape Town, South Africa
The spatial distribution and diversity within bacterioplankton assemblages in four coastal sites along the southern points of the Atlantic Ocean were examined using the Illumina high-throughput that targets 16S rRNA genes to examine indigenous bacterial assemblages in the littoral zones along the coast of the ocean. Results of the study showed very similar bacterial representation between the coastal sites with majority...

Biochemical and molecular characterization of yeasts isolated from Nigerian traditional fermented food products
Yeasts are very important in food production by affecting the quality and safety of different food products. Yeasts are commonly used in the production of beer, wine and bread; but many yeast species have been isolated from different African fermented foods. The present study aims to determine the biodiversity of yeasts isolated from selected Nigerian fermented foods. A combination of phenotypic and molecular tests were...

Quality assessment of bacterial load present in drinking water in Woreta town, Ethiopia
Access to adequate and safe water is a universal human need. Lack of safe and adequate water supply causes health risk and the situation is serious in developing countries The aim of this study was to determine the bacterial load, physicochemical quality of drinking water in wells, reservoir, taps and household storage containers water samples and to investigate the hygiene and sanitation practices of...

Differential traits of rhizobia associated to root-nodules of gum acacia (Senegalia senegal), shittah tree (Vachellia seyal), pigeon pea (Cajanus cajan L) and cowpea (Vigna unguiculata)
In the present study, rhizobia partners of gum acacia (Senegalia senegal L.), shittah tree (Vachellia seyal), pigeon pea (Cajanus cajan L.) and cowpea (Vigna unguiculata L.) were characterized for their specific traits to each of the three host plants. In total 12 soil samples were collected and used to trap root-nodule rhizobia. Averagely, 24 rhizobia strains were isolated, of which 3, 4, 6 and 11 were respectively...

Assessment of microbiological quality and drug resistance patterns of raw vegetables irrigated with Hasassa River, West Arsi Zone, Oromia Region, Ethiopia
Irrigation scheme is among the major transmission modes of enteric human pathogens. Irrigation of vegetables with polluted water and untreated wastewater is a common practice worldwide. This practice is common in urban areas of low-income countries including Ethiopia, where there is increasing demands for fresh vegetables with poor wastewater treatment. The aim of the present study was to assess the microbial quality...

Leishmanicidal, cytotoxic, antimicrobial and enzymatic activities of Diaporthe species, a mangrove-isolated endophytic fungus
This study evaluated the biotechnological potential of the endophytic fungus Diaporthe species, which is isolated from Brazilian mangroves. In vitro studies have investigated the antimicrobial activity of Diaporthe spp. against human pathogens, such as Escherichia coli, Staphylococcus aureus, Salmonella enteritidis, and Candida albicans, as well as phytopathogenic fungi, such as Colletotrichum species, Ceratocystis...

Molecular identification of bacterial isolates from the rhizospheres of four mangrove species in Kenya
Mangrove ecosystems provide a unique ecological niche for diverse microbial communities. This study aimed to identify bacterial isolates from the rhizospheres of four mangrove species (Sonneratia alba, Rhizophora mucronata, Ceriops tagal and Avicennia marina) using the 16S rRNA gene analysis approach. Rhizospheric sediment samples of the mangroves were collected from Mida creek and Gazi bay, Kenya, using standard...

Isolation and identification of microorganisms in selected cosmetic products tester
Components of cosmetics supply a rich medium for the growth of microorganisms. Customers usually like to try cosmetics before buying them. Repetitive use of the eye and makeup tester by different customers may become a potential vector of microbial pathogens. The major goal of this study was to evaluate microbial contamination of the cosmetics that are accessed as an unsealed make-up tester in the selected makeup shops...

Isolation, characterization and biotechnological potential of tropical culturable rhizospheric fungi from four mangrove species in Kenya
Fungi play important roles, as both decomposers and plant symbionts in mangrove ecosystems. Their ability to survive extreme environmental conditions makes them potential rich sources for recovery of novel bioactive compounds. In this study, biotechnological potential of fungi recovered from the rhizospheres of four mangrove species (Sonneratia alba, Rhizophora mucronata, Ceriops tagal and Avicennia marina) was...
