Isolation of Serratia fonticola from pirarucu Arapaima gigas

Abstract

The pirarucu, Arapaima gigas (body weight = 18.3 kg and total length = 102 cm) which had been reared in one of the private commercial aquaria for exhibition was found dead and submitted for diagnostic examination. A pure bacterial culture was isolated from the kidney, which was enlarged, and contained fluids. Result of the bacterial identification yielded Serratia fonticola. This paper describes the first isolation of S. fonticola from pirarucu.
