Susceptibility Of Aeromonas hydrophylla Bacteria Isolated From Unhealthy Baung Fish (Mystus nemurus) Towards Antimicrobial Agents = Kerentanan Bakteri (Aeromonas Hydrophila) Hasil lsolasi dari Ikan Baung (Mystus Nemurus)

ABSTRACT The susceptibility of Aeromonas hydrophila isolated from ikan baung (Mystus nemurus) to antimicrobial agents was carried out. The objective of study is to know the kind of antimicrobial agents for the control aeromonasis of Mystus nemurus. Tryptic soy agar (TSA) plate consisted 106 cells/plate of A. hydrophila on its surface was kept paper disk consisted antimicrobial agent, than incubated on 30°C for 24 hours. The results showed that from 10 isolates to be tested, 5 isolates were resistant, 2 isolates were intermediate and 3 isolates were sensitive to tetracycline and chloramphenicol respectivelyone isolate was resistant, 6 isolates were intermediate and 2 isolates were sensitive to nalidixic acid. Minimal in hibitory concentration (NC) of tetracycline and chlorampenicol to the sensitive isolates were 0.5 ppm respectively. Keywords: The susceptibility, Aeromonas hydrophila, antimicrobial agent

SUSCEPTIBILY OF <i>Aeromonar hydrophylla</i> BACTERIA ISOLATED FROM UNHEALTHY BAUNG FISH (<i>Mystus nemurus</i>) TOWARDS ANTIMICROBIAL AGENTS

The susceptibility of Aeromonas hydrophila isolated from ikan baung (Mystus nemurus) to antimicrobial agents was carried out. The objective of study is to know the kind of antimicrobial agents for the control aeromonasis  of Mystus nemurus. Tryptic soy agar (TSA) plate consisted 106 cells/plate of A. hydrophila on its surface was kept paper disk consisted antimicrobial agent, than incubated on 30 0C for 24 hours. The results showed that from 10 isolates to be tested, 5 isolates were resistant, 2 isolates were intermediate and 3 isolates were sensitive to tetracycline and chloramphenicol respectively; one isolate was resistant, 6 isolates were intermediate and 2 isolates were sensitive to nalidixic acid. Minimal in hibitory concentration (MIC) of tetracycline and chlorampenicol to the sensitive isolates were 0.5 ppm respectively.   Keywords: The susceptibility, Aeromonas hydrophila, antimicrobial agent

POTENSI DOLOMIT DALAM PENANGGULANGAN PENYAKIT "EPIZOOTIC ULCERATTVE SYNDROME (Aphanonxyces sp.)" PADA IKAN LELE DUMBO, Clarias sp.

Penelitian ini bertujuan untuk mengetahui potensi kapur dolomit untuk memanipulasi kadar alkalinitas air dalam penanggulangan penyakit "Epizootic Uleerative Syndrome" EUS pada ikan lele dumbo. Enam buah kolam masing-masing berukuran 50 mz digunakan pada percobaan ini.Tiga buah kolam diberi kapur dolomit hingga total alkalinitasnya mencapai 100 ppm, sedangkan alkalinitas pada tiga buah kolam lainnya dibiarkan berfluktuasi secara alamiah
