碩士 / 國立臺灣大學 / 獸醫學研究所 / 93 / Antimicrobials susceptibity of normal isolated bacteria at fish farms are one of the fundamental bases of clinical therapy. The aims of these studies were to investigating the distribution of selected bacteria and their antimicrobials susceptibility profiles at seawater and freshwater fish farms in Taiwan. In the seawater (freshwater) fish farms, six different sources which including 738 (255) related samples were collected. A total of 1682 (638) target bacteria were isolated. Regardless the sources of samples, antimicrobial susceptibility results indicated that all the Gram-negative bacteria were highly resist to sulfamethazine, sulfadiazine, amoxicillin and chloramphenicol. However, these bacteria still sensitive to oxolinic acid, enrofloxacin, ciprofloxacin, flumequine and part of aminoglycosides. All the Gram-positive bacteria were highly resist to sulfamethazine and sulfadiazine but quinolone, kanamycin and gentamicin were sensitive. The susceptibility concentration ranges cross-different species of bacteria over different drugs were widely distributed. The isolated bacteria with multiple resistances to selected antimicrobials were common. Our results can be used to estimating the antimicrobials resistance of target organisms in aquaculture. It also can be used for the selection of therapeutic drugs on veterinary clinical practice.
