| Summary: | Silver rasbora (Rasbora argyrotaenia) is one of Indonesian local freshwater fishes
species that have high economic value. One of bacterial diseases that probably infected to
silver rasbora cultivation is Streptococcus agalactiae that caused streptococcosis. There was
limited information about effect of Streptococcus agalactiae infection to hematological profile
in silver rasbora has never been reported before. The aims of these studies were to determine
the hematological profile of silver rasbora that experimentally infection with Streptococcus
agalactiae. A total of four hundreds silver rasbora (6 ± 0.1 cm length and 3.6 ± 0.2 grams
weight) were intramuscularly infection with 0,1 mL Streptococcus agalactiae in different
density, include 104
, 106
, 108
, 1010 and NaCl physiological solution as negative control.
Observation of hematological profile was carried out by blood examination post infection
which included total erythrocytes, total leukocytes, differential leukocytes (percentage of
lymphocyte, neutrophil, and monocyte) and hemoglobin levels. Hematological profile in silver
rasbora (Rasbora argyrotaenia) infected by Streptococcus agalactiae showed an increase in
neutrophil and monocyte percentage and showed a decrease in total erythrocytes, hemoglobin,
total leukocytes and lymphocyte percentage. Further studies were needed to prevent the
Streptococcus agalactiae infection using herbal medicine. |
