“…This is a good result considering that MRSA is an increasing global problem, and it only can be affected by vancomycin and teicoplanin (Lee et al . ). On the other hand, no highest antimicrobial activity against E coli ESBL was evident.…”

“…Infectious diseases are a long-lasting and a serious public health problem that affects people all over the world [4]. Today, numerous bacteria, including Staphylococci, Enterococci, Gonococci, Streptococci, and others, demonstrate multidrug resistance [5]. There is an urgent need to look for novel compounds for drug development, industry, and agricultural applications [6][7][8][9].…”

Endophytic fungi, particularly from higher plants have proven to be a rich source of antimicrobial secondary metabolites. The purpose of this study is to examine the antimicrobial potential of three endophytic fungi Aspergillus sp. SA1, Aspergillus sp. SA2, and Aspergillus sp. SA3, cultivated from Nigella sativa seeds against Staphylococcus aureus (ATCC 9144), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Klebsiella pneumoniae (ATCC 13883), MRSA (ATCC 33591), and human pathogen Candida albicans (ATCC 10231). Furthermore, the most active cultivated endophytic fungi were molecularly identified via internal transcribed spacer (ITS) sequencing. HR-ESIMS guided approach has been used successfully in chemical profiling of 26 known bioactive secondary metabolites (1–26), which belongs to different classes of natural compounds such as polyketides, benzenoids, quinones, alcohols, phenols or alkaloids. Finally, in-silico interactions within active site of fungal Cyp51 and bacterial DNA gyrase revealed possibility of being a hit-target for such metabolites as antimicrobials.

Marine endophytic bacteria are a valuable source of novel antibacterial in combating pathogenic isolates of methicillin-resistant Staphylococcus aureus (MRSA), a global nosocomial problem today. The aim of this study was to assess in vitro anti-MRSA activity of extracts from bacteria endophyte of marine sponge Haliclona fascigera collected from Setan Island, South Coast of West Sumatra, Indonesia. Anti-MRSA activity test carried out by the agar diffusion method using paper disk. The endophytic bacteria from sponge were isolated using dilution method and pour plate method on NA media. From the sponge were obtained 26 isolates of bacterial endophytic then propagated in NB media. The liquid media was then extracted using ethyl acetate solvent. Antimicrobial activity test carried out by the agar diffusion method using paper disk. The antibacterial activity assay was conducted with the extract concentrations of 5 %. Chloramphenicol was used as a positive control agent. The zone of inhibition was measured and expressed in millimeters. There were 12 isolates of the bacteria that considered active to MRSA. Mean of inhibition zones ranged from 11.1±0.17 to 15.17±0.76. Characterization and identification of endophytic bacteria were conducted to several bioactive bacteria. The identification method was performed using Gram staining and biochemical test.
