Background More people—in both developing and developed countries—now use, and are favourably disposed to, traditional medicine. Musa paradisiaca (plantain) is used extensively in traditional medicine across continents. In this review, we investigated the scientific justification of this extensive usage. Main body Generally, several studies validate usage in infectious diseases, but limited antiviral and in vivo reports exist. The mechanistic elicitation of antimicrobial activity has similarly not been ascertained. Contrarily, data abound from rigorous studies on physiological conditions. Activity across categories is tied to the potent phytosterols duo of stigmasterol and β-sitosterol; and the triterpenes viz. cycloeucalenone, 24-methylene-cycloartanol, and 31-norcyclolaudenone; present in plantain. Toxicity studies, while finite, suggest general safety and tolerance. Conclusions Findings in the studies reviewed projects plantain as a veritable source for drug bioprospecting that will be of benefit to scientific research and pharmaceutical industries.

The aim of the study was to investigate the microbial populations of water and biofilm samples from seven hand dug wells in Ilorin, Nigeria, which are for private and public use. Physicochemical parameters such as pH, turbidity, total dissolved solids, temperature, conductivity, dissolved oxygen and biological oxygen demand were determined. Biofilm growths were induced from water samples obtained from selected wells. Twenty bacteria isolated were identified using morphological and biochemical characteristics as well as molecular methods and includes Shigella sonnei, Shigella dysenteriae, Micrococcus luteus, Bacillus sphaericus, Salmonella enteritidis, Proteus mirabilis strain IK-MB4-518F, Bacillus licheniformis strain RH104, Bacillus subtilis, Erwinia sp., Proteus vulgaris, Yersina sp., Bacillus cereus, Staphylococcus aureus, Serratia marcescens, Pseudomonas aeruginosa strain GS1, Pseudomonas aeruginosa strain 218B, Staphylococcus epidermidis, Vibrio sp., Escherichia coli and Bacillus pasteurii. Total bacterial count ranged from 1.8×104-1.53×106 cfu/ml. Water samples from these wells are therefore not potable and some of the isolates are potential health hazards to human population.
