| Abstract: | Present article consists the in vitro antibacterial study carried out
using leaf extracts of Rhizophora
mucronata L.,
a mangrove plant. Extracts were screened for antibacterial activity against
multi-drug resistant Vibrio harveyi and
Vibrio campbellii. The same were
isolated from Lobster’s larvae hatchery water. Antibiotic resistance and
sensitivity of
the isolated Vibrio spp. were tested
with Hi-Media antibiotic disc. Out of total eight antibiotics discs used, V. harveyi
was found highly resistant to ampicillin, oxacillin, cephalothin, vancomycin,
erythromycin, and clidamycin, while, it
was sensitive towards chloramphenicol (19 mm) and gentamycin (9 mm). Whereas, Vibrio campbellii was found highly
resistant to ampicillin, oxacillin, cephalothin, vancomycin, and erythromycin. Vibrio campbellii was highly sensitive
to chloramphenicol (20 mm), and moderately sensitive to clindamycin (9 mm), and
gentamycin (14 mm). Chloroform
leaf extract of Rhizophora mucronata
L. was found to be the most active one against both Vibrio spp., while, hexane, ethyl acetate, and methanol extract
revealed moderate activity against both Vibrio
spp. However, distilled water extract did not have any activity.
Chloromphenicol from the Hi-Media antibiotic and chloroform extract from Rhizophora mucronota leaves can be used
as a source of alternative compound to control the Vibrio spp. which infects the Lobster’s larvae. |
