| description | The objectives of the research were to isolate, to identify Streptococcus sp. and to
determine the causative disease of their pathogenicity on tilapia (Oreochromis sp.). The
samples were collected from three different areas in Sleman and Klaten Regency. The
bacteria were isolated from the samples then continue by postulate Koch test by
intramuscular injection at 0,1 ml/fish and observed for it�s symptoms. The characterization
and identification were done from morphology of bacterial colony and cell, physiological
and biochemical properties. Pathogenicity test were done by injection at the various
concentration as 104,106,108cfu/fish into the tilapia with size range of 5 to 7 cm and
determined it�s Lethal Dosage value of 50 (LD50). The 32 isolates have been purified and
25 isolates among them were Streptococcus sp .Twelve isolates confirmed as pathogens
which divided into 8 isolates (CK II.1, MK III.2, JT V.1, JT V.2, JT VI, JT VII.2, JT VIII,
and JT IX.2.) were identified as S. agalactiae and 4 isolates (CK I.1, MK IV, MK V.2, and
JT V.3) were identified as S. iniae. The general symptoms of Streptococcus sp. including
the abnormal swimming behavior and exophthalmos. The isolate of S. agalactiae (CK II.1,
MK III.2 and JT VI) were virulent with the LD50 4,36.105 |
