Antimicrobial efficiency of thebutanol, methanol and chloroform extracts derived from the digestive gland, tube feet, spine and gonad of the starfish, Pentacerastermammillatuswere examined against three human pathogenic bacteria (Streptococcus mutans, Staphylococcus aureus and Klebsiella pneumoniae) three fish pathogenic bacteria (Vibrio harveyi, Proteus mirabilius and Aeromonous hydrphila) and three fungal pathogens (Aspergillus flavus, Aspergillus niger and Rhizopus stolonifer). The antimicrobial activity was evaluated by measuring the zone of inhibition using disc diffusion method. The butanol extract of the digestive gland inhibited the growth of all the tested bacteria and a pathogenic fungus R. stolonifer, the tube feet arrested the growth of all the bacterial pathogen and two fungal pathogens A. flavus and R. stolonifer; the spine arrested the growth of S. mutans and S. aureus and the gonad inhibited the growth of S. mutans and all the three fish pathogenic bacteria. The chloroform and methanol extract of all the tissues could inhibit the growth of only a few pathogens compared to that of the butanol extract. However, the chloroform extract of spine inhibited the growth of more number of pathogens than the butanol and methanol extract.
