The aims of this study are to identify and isolate pathogenic gram-negative bacteria in the liver of the plecos from Lapompakka and Sidenreng Lakes and to observe the histopathological changes in liver identified with gram-negative bacteria infection. 10 samples were collected from both lakes with each 5 representing each lake. Identification and Isolation of gram-negative bacteria was performed through culture of pleco's liver swab results in MacConkey media using gram staining method and were continued by biochemical testing using VITEK 2 System. The acquired results indicated that there were 8 different species of gram-negative bacteria isolated and all of them were pathogenic to the plecos. The species of bacteria includes Klebsiella pneumoniae, E.coli, proteus sp., Acinetobacter baumannii, Aeromonas sobria, Enterobacterb cloacae complex...
