Antibacterial property of crude extract from stem-bark and leaves of Rhizophora apiculata against selected bacterial fish pathogens

ecently the wide range of commercial antibiotics in fish feed for aquaculture practices has led to antibacterial resistance, environmental pollution and residue build-up in fish tissue. Therefore new sources of antibiotics from natural sources need to be investigated to circumvent these problems....

Rhizophora apiculata has been reported to have high antimicrobial activity due to the high concentration of tannin in the bark of the tree. Methods: Based on these contexts, this study was conducted to measure the antimicrobial activity of ethanol, ethyl acetate and distill water extracts from the stem-bark and the leaves of R. apiculata. 9 species of bacteria consist of B. subtilis, S. aureus, S. epidermidis, P.aeruginosa, P. mirabilis, H. alvei, V. alginolyticus, V. paraheamolyticus and E. coli were tested to measure their susceptibility to the extracts. The extracts were dissolved into 2 different concentrations which were 10 mg/mL and 50 mg/mL or 10 ug/disc and 50 ug/disc respectably, to determine the inhibitory effect of the extract upon the bacterial fish pathogen. Results: 2 species of Gram-positive bacteria which were B. subtilis and S. epidermidis have shown positive results with 9.0 mm to 16.0 mm of inhibition zone respectably while the other bacteria were resistant to the extract concentration administered.
