| description | The present study indicates that the evolution of
intensive marine cage culture farms in Malaysia can be a
potential risk for outbreaks of vibriosis under
unfavourable environmental conditions . The cage culture
farm harboured significantly higher numbers of bacteria in
the sediment and underlying waters compared to the
surrounding waters indicating that the farm serves as a
reservoir for bacteria. This is due to the rapid build up
of organic waste from feed and excretion matter from fish.
Vibrios isolated from the cage culture farm were
found to be virulent to sea bass fingerling.
Intraperitoneal injections of whole live bacterial cells
of the chosen isolate , Vibrio alginolyticus caused higher
mortalities compared to the extracellular products ( ECP)
of the bacteria.In the intramuscular injection ( 1M ) ,
only whole live bacterial cells of V. alginolyticus caused 50% mortalities when injected into sea bass finger lings . |
