A First Record of Sphingobacterium thalpophilum Isolated from Coptodon zillii and Oreeochromis aureus in the Al-Diwaniya River/Iraq

Abstract

Abstract This investigation was done to determine whether C. zillii and O. aureus in the Al-Diwaniya Stream included every possibly harmful species of Gram-negative microbes. 100 C. zillii and 100 O. aureus fish samples were taken from the Al-Diwaniya River between Apr 2021 and Mar 2022. bacteria he was found us the VITEK 2 system. Here, we reported the discovery of S. thalpophilum, which was isolated from the intestine, fins, and gills of C. zillii and O. aureus, for the first time in Iraq. S. thalpophilum were found in C. zillii with a different proportion as follows: skin 1%, gills 70%, fins 24%, and intestine 5%; and in O. aureus with a different percentage as follows: skin 1%, gills 49%, fins 30%, and intestine 20%. Additionally, the VITEK 2 system was utilized to antibiotic sensitivity. The findings showed that the bacteria were susceptible to minimum inhibitory concentration (MIC) of imipenem, ciprofloxacin, and levofloxacin (0.25 g/ml), as well as to S. thalpophilum, but resistant to cefazolin (>= 61 g/ml).
