Leaves of Ocimum gratissimum and Newbouldia laevis were subjected to cold maceration in ethanol, ... more Leaves of Ocimum gratissimum and Newbouldia laevis were subjected to cold maceration in ethanol, ethyl acetate, and water for 24 hours. The extracts which on phytochemical screening showed the presence of alkaloids, flavonoids, saponins, tannins, glycosides, and phenols, were tested for antimicrobial activities. Various concentrations of the plant extracts (200, 100, and 50 mg/ml) were assayed for antibacterial activity using the agar well diffusion method. Two Gram-positive (Staphylococcus aureus and Streptococcus pyogenes) and four Gram-negative (Escherichia coli, Klebsiella aerogenes, Salmonella typhi, and Pseudomonas aeruginosa) bacteria were used for the study. The ethanol extract of O. gratissimum showed the highest zone of inhibition against E. coli with 18mm at 200mg/ml concentration, followed by ethyl acetate and aqueous extracts with 15 mm and 8 mm, respectively. Ethanol extract of N. laevis displayed the best activities against E.coli and S. aureus with both displaying in...

Aquatic snail species of two adjoining Rivers (Otamiri and Nwaorie Rivers) in Owerri Southeastern... more Aquatic snail species of two adjoining Rivers (Otamiri and Nwaorie Rivers) in Owerri Southeastern Nigeria was surveyed between December 2008 and May 2009. The study identified 231 aquatic snail species. Snail species collected were Bulinus globosus (29.9%), Lymnaea natalensis (59.3%), and Melanoides sp. (10.8%). There was an observed statistical difference (P < 0.05) in the occurrence of the snail species. Otamiri River recorded 93.3% species while Nwaorie recorded 6.1% - a significant difference (P < 0.05) also existed. Of the total number of snail species collected, none was found shedding cercariae. Therefore, surveillance is needed to avoid emergence of diseases vectored by this snail species in the study area.
