The use of Cattapa Leaves Terminalia cattapa as Preventive and Curative Methods in Patin Catfish Pangasionodon hypophthalmus Infected With Aeromonas hydrophila

Abstract

<p>Motile Aeromonad Septicaemia (MAS) caused by <em>Aeromonas hydrophila</em> induced serious epidemics of ulcerative disease in freshwater fish including patin catfish <em>Pangasionodon hypophthalmus</em>. <em>In vitro</em> study for antibacterial test of cattapa leaves <em>Terminalia cattapa</em> (TC) were done previous to the <em>in vivo</em> test. The <em>in vitro</em> susceptibility test was performed at the dosages of 30, 60 and 90 g/l TC. At the <em>in vivo</em> test, fish were injected intramusculary with TC at the dosages of 60 g/l for the prevention and 120 g/l for curative efficacy. Results from blood picture, clinical sign and mortaliyt showed that TC were better and more effective as preventive than curative for MAS in patin catfish.</p> <p>Keywords :  <em>Terminalia cattapa</em>, <em>Aeromonas hydrophila</em>, patin catfish</p> <p> </p> <p>ABSTRAK</p> <p>Penyakit MAS (<em>Motile Aeromonad Septicaemia</em>) yang disebabkan oleh <em>Aeromonas hydrophila</em> sering menyebabkan wabah penyakit tukak pada ikan-ikan air tawar termasuk pada ikan patin <em>Pangasionodon hypophthalmus</em>. Uji antibakteri secara <em>in vitro</em> dari daun ketapang <em>Terminalia cattapa</em> (TC) dilakukan sebelum uji <em>in vivo</em>. Pada uji <em>in vitro</em> dilakukan pengujian aktivitas antibakteri TC terhadap <em>A. Hydrophila</em> pada dosis TC 30, 60 dan 90 g/l. Pada uji <em>in vivo</em>, ikan diinfeksi secara intramuskular dengan TC, untuk pencegahan dengan dosis 60 g/l TC dan pengobatan pada dosis 120 g/l TC. Hasil yang diperoleh dari gambaran darah, gejala klinis dan kematian ikan patin menunjukkan bahwa TC lebih baik dan sangat efektif untuk pencegahan daripada pengobatan untuk penyakit MAS pada ikan patin.</p> Kata kunci: <em>Terminalia cattapa</em>, <em>Aeromonas hydrophila</em>, ikan patin
