Abstract

This work reports the results of a screening programme based on marine sponge extract from the Southeastern Mandapam coast. Sponge species was collected by scuba diving in rocky shores, from 2010, were screened for haemolytic, neurotoxic and antibacterial activities. Methanolic extract of the sponge species was obtained and the crude extract of Callyspongia diffusa induced haemolysis (32 HU/g and 16 HU/g) in chicken and goat erythrocytes. The extract of C. diffusa showed specific neurotoxic activity on sea shore crab. The screening for antibacterial activity showed that the methanolic extract of sponge was active against ten species of bacterial pathogens. The maximum zone of inhibition was 10mm against Pseudomonas aeuruginosa and Salmonella paratyphii while the minimum inhibition zone was 7mm, against Salmonella typhii and Klebsiella pneumoniae respectively.
