Abstract: Two dominant bacteria were isolated from the hepatopancreas of the diseased mud crab (Scylla paramamosain). The isolated strains were identified as Vibrio sp. and Shewanella through analyzing phenotypic characteristics and 16S rDNA sequence. Antibiotic sensitivity patterns of the two kinds of bacteria were evaluated against 15 antibiotics. Results showed the the isolated strain was highly sensitivity to 3 antibiotics including enrofloxacin, florfenicol and doxycycline, but resistant to 12 other antibiotics.

Key words: Scylla paramamosain, Vibrio sp., Shewanella, 16S rDNA, antibiotic sensitivity
