Detection of Drug-Resistant Kluyvera intermedia from Zoacys dhumnades

Drug-Resistant K. intermedia from Z. dhumnades

Abstract

Zoacys dhumnades is native to china and has important economic and medicinal value, but the pathogenic microorganisms have been reported rarely. Kluyvera intermedia is usually considered a commensal. In this study, Kluyvera intermedia was first isolated from Zoacys dhumnades identical by the 16SrDNA sequence, phylogenetic tree analysis, and biochemical tests. Cell infection experimental did not find cell morphology change significantly compared to control with pathological organs homogenates from Zoacys dhumnades. Antibiotic susceptibility shown Kluyvera intermedia isolates were sensitive to 12 kinds of antibiotics and resistant to 8 kinds of antibiotics. Resistant antibiotic genes screening display gyrA, qnrB, and sul2 were found in Kluyvera intermedia. This is the first report of Kluyvera intermedia associated fatality with Zoacys dhumnades suggesting the need for continuous monitoring of nonpathogenic bacteria antimicrobial susceptibility from human, domestic animals and wildlife.
