The emergence of new infectious diseases, the resurgence of several infections that appeared to have been controlled, and the increase in bacterial resistance have created the necessity for studies directed towards the development of new antimicrobials; considering the failure to acquire new molecules with antimicrobial properties from marine sponges. The objective of this study was to evaluate screening of antimicrobial activity of seven sponges extract from Pasir Putih, East Java against some Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gram negative (Escherichia coli and Klebsiella pneumoniae) as well as drug-resistant bacteria (S. aureus and Pseudomonas aeruginosae) using the agar diffusion method and phytochemical screening of the extract. The findings show that the extract, Xestospongia testudinaria has a stronger antibacterial activity against bacterial pathogens S. aureus, E.coli, K. pneumoniae, Salmonella typhi and bacteria resistant P. aeruginosa MDR and S. aureus MRSA compared to other sponge extract. In conclusion, the showed X. testudinaria ethanol extract was more active than other sponge extracts.
