ABSTRACT

 

Prominent pathogenic enteric are Salmonella, Shigella and Escherichia. The strains of E. coli are the main organisms for causing diarrhea. The antibacterial characteristics of methanol, acetone, diethyl ether and ethanol extracts of brown seaweed Sargassum boveanum from the three shores (Buleji, Paradise Point and Manora) of Karachi coast were tested in vitro for their antidiarrheal activities against diarrhea causing E. coli in children between the ages 2 weeks to 10 years old by disc diffusion method. The diarrhea samples were taken from civil hospital of Karachi, Pakistan. Acetone was the best extraction against the E. coli used in this experiment. While some ethanol extraction also showed the positive results. There was no significant result observed between the diethyl ether and methanol extracts of each sample of Sargassum boveanum. In majority of samples E. coli diarrhea causing organism was found while in some cases Vibrio cholera also detected.
