양식어류와 사육수로부터 분리된 세균의 약제 감수성 경향 비교 = Drug Susceptibility of Bacteria Isolated from Fish and Water of Fish Farms

다국어 초록 (Multilingual Abstract)

Rapid identification of the sensibility of fish pathogens against chemotherapeutic agents
is the most important to treat diseases in fish farms. This study was performed to know the
relationships between the drug resistance of bacteria isolated from a fish farm water and that
from fish. Two hundred and eighty eight strains were isolated from fish (FB) and 293 isolates
from water (WB) of 7 fish farms. Five kinds of antibacteria1 agents were used for the determination
of MICs; amoxicillin (AMPC), erythromycin (EM), doxycycline (DOXY), oxo1inic acid
(OA) and norfloxacin (NFLX). AMPC resistance bacteria were appeared in WB and FB of
6 farms but DOXY or OA resistance bacteria were detected from only 2 farms. Resistance
marker of bacteria against antimicrobial agents was showed complex type with 1 to 4 drugs.
The drug sensibility patterns of isolates were similar in 28 among 35 experimental cases.
Therefore, we suggest that the sensibility pattern of WB to various antibacterial agents was
related to the patterns of FB.
