The isolate of S.agalactiae ГўВЂВ“ N14G was used as a master seed on vaccine production.

PENYAKIT IKAN NILA SKIN

Observation using scanning electron microscope of fish skin showed that the bacterial isolate might attach to the fish so that might press infection of pathogen in tilapia.The research with the aim to know the effectivity (yield gap) of the application of Streptococcus agalactiae vaccine (pure whole cell) in prevention of streptococcosis on tilapia (Oreochromis niloticus) culture has been carried out. with amount of healthy fish had seen until end of day seupervision respectively percentage 86% and 84%. PB17 most to inhibit infection of Saprolegnia sp. However test of controlling saprolegniosis in tilapia indicated that isolate Bacillus sp. PB17 isolate had ability better than other antagonistic bacteria isolate to inhibit all of water mold isolate. BK17 and PB08) had ability to inhibit of water mold with diameter of inhibition zone 8,50 mm, 8,04 mm and 7,55 mm. Antagonism test in vitro showed that three antagonistic bacterial isolate (Enterobacter sp. was most pathogenic, with 90% death and infection and was used for further test. Test of pathogenicity indicated that Saprolegnia sp. Three isolates of water mold were isolated from infection of catfish eggs and tilapia. in tilapia (Oreochromis niloticus) has been done in the Laboratory of Microbiology, Bureau of First Class Fish Quarantine Polonia and Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Sciences, University of North Sumatra, Medan. The study about ability of antagonistic bacteria to inhibit infection of Saprolegnia sp.
