Abstract
The study was conducted from January to May 2019 at Tien Giang University to evaluate the antibiotic resistance status of Vibrio parahaemolyticus and propose appropriately antibiotics to treat diseases on farmed shrimp in Bac Lieu. V. parahaemolyticus bacteria samples were collected and isolated from pond mud, pond water, river water and diseased shrimp by the method of Nirunya et al. (2008). V. parahaemolyticus was identified by Nam Khoa IDS 14GNR kit. Antibiogram were performed and evaluated by diffusion method on agar plates according to CLSI standard (2016) with 17 antibiotics commonly current using today in shrimp farming. The results showed that Apramycin was resisted highest with the rate of 73.3%. The least resistant antibiotic was Streptomycine, Doxycycline, Florphenicol, Chloramphenicol and Norfloxacine at the same rate of 0%. Doxycycline and Chloramphenicol had been sensitives highest with the same rate of 100%. The lowest sensitivity rate was Enrofloxacine (6.7%). The rate of antibiotic resistance of V. parahaemolyticus that was isolated in 3 districts of Hoa Binh, Dong Hai and Gia Rai of Bac Lieu province were 15.3%, 17.7% and 31.8%, respectively and it wasn’t significantly difference (p <0.05). Analytical results show that Doxycycline, Streptomycine and Florphenicol could be used to treat effectively on white leg shrimp disease caused by V. parahaemolyticus in Bac Lieu province.
