Summary: | Serratia spp. is one of the significant human pathogen. Some Serratia spp. especially Serratia marcescens
contain a lot of human clinical infection history as well as interesting taxonomic, military experimentation and
medical experiment. Currently, Serratia marcescens and Serratia liquefaciens have been isolated as causative
agents of numerous outbreaks and opportunistic infections. As the species appear to be common environmental
organisms, large number of nosocomial infections due to these bacteria can be explained. Thus, molecular
characterization of several Serratia spp. become the main objective of this research as an approach to gain
better identification and characterisation of various of Serratia spp. In this study, antibiotic susceptibility
and genetic diversity of Serratia spp. isolated from aquaculture environment and river water of Rayu river
were determined. The levels of resistance of the Serratia isolates towards nineteen antibiotics were tested.
These isolates displayed resistance towards most of the antibiotics tested but the level of resistance vary among
the species. Genetic characterization of Serratia spp. were carried out by using GTGs-PCR which clustered the
Serratia isolates into three groups based on DNA fingerprinting by using Paleontologi statistic software. The
results of this study suggest that the Serratia isolates from aquaculture environment and river water derived a
mixture of sensitive and resistant strains with diverse genetic contents. |
