Whole plant-parts of Bidens pilosa were powdered and extracted in concentrated hexane, acetone, ethanol, methanol and water. The extracts were tested for antimicrobial activity against Escherichia coli (25922), Bacillus subtilis (ATCC 6051), Enterococcus faecalis (51299) Staphylococcus aureus (ATCC 29213) and Pseudomonas aeruginosa (ATCC127853), using standard microbiological techniques. Active crude extracts were macerated in concentrated methanol and tested for secondary metabolites including tannins, saponins, alkaloids, cardiac glycosides, anthraquinones, steroids and flavonoids using standard phytochemical procedures.

Diarrhoea is a major cause of morbidity and mortality in rural communities in Africa, particularly in children under the age of five. This calls for the development of cost effective alternative strategies such as the use of herbal drugs in the treatment of diarrhoea in these communities. Expenses associated with the use of orthodox medicines have generated renewed interest and reliance on indigenous medicinal plants in the treatment and management of diarrhoeal infections in rural communities.

Antimicrobial resistance to commonly-used drugs has generated a considerable interest in the search for novel therapeutic compounds from medicinal plants. As an ongoing effort of this search, the susceptibility of 32 clinical strains of H.

Solvent-extracts of selected medicinal plants; Combretum molle, Sclerocarya birrea, Garcinia kola, Alepidea amatymbica and a single Strychnos species were investigated against 30 clinical strains of H. pylori alongside a reference control strain (NCTC 11638) using standard microbiological techniques.

In order to identify novel sources of such agents, the antimicrobial activity of five solvent extracts of the stem bark of Sclerocarya birrea was investigated against 30 clinical strains of H. pylori and a reference strain NCTC 11638 using standard microbiological techniques.
