Abstract

The purpose of this study was to analyze the phylogenetic relationship of Gram negative bacteria (3strains of Salmonella typhi, 1 strain of Escherichia coli, 1 strain of Serratia marcescens, and 3 strains of Enterobactercloacae) of Enterobacteriaceae family in positive Widal blood cultures based on 16S rRNA gene sequences. Theresults respectively showed that each two 16S rRNA gene clones of Serratia marcescens KD 08.4 had a closerelationship with 16S rRNA gene of Serrratia marcescens ATCC 13880 (similarity: 99.53-99.8%), Eschericia coliBA 30.1 with Eschericia coli ATCC 11775T (similarity: 99.38-99.67%), Salmonella typhi BA 07.4, Salmonella typhiKD 30.4, and Salmonella typhi SA 02.2 with Salmonella typhi ATCC 19430T (similarity: 99.4-100%) as well as theisolates of Enterobacter cloacae SA 02.1, Enterobacter cloacae BA 45.4.1, one 16S rRNA gene clone of Enterobactercloacae TG 03.5 with Enterobacter cloacae ATCC 23373 (similarity: 99.0-99.87%).

Abstract

The purpose of this study was to determine the chemosystematic of 14 strains of bacteria in blood cultures from Semarang using 1 reference strain S. typhi NCTC 786, based on the total protein profi les with the similarity relationship analysis based on Simple Matching Coeffi cient (SSM) analysis and algorithm methodof unweighted pair group with averages (UPGMA) presented in a dendrogram. The results showed that thechemosystematic based on the total protein profi les using SDS-PAGE method can classify the member ofbacterial strains of each species. The Clusters respectively consist of 4 strains of S. typhi (similarity: 89.7%),2 strains of Ser. marcescens (similarity: 89.7%), two strains of E. coli, and one strain of Salmonella ssp, S. typhi NCTC 786 (similarity: 100%). Those three incorporated clusters had the similarity value of 75.3%. Those four strains of Ent. cloacae composed in one cluster (similarity: 100%) are incorporated in a cluster consisting of one strain of Kleb. pneumoniae (similarity: 92.9%). Both clusters were incorporated in a cluster consisting of S. typhi NCTC 786 (similarity: 67.9%).Key words: Enterobacteriaceae, chemosystematic, blood cultures, protein profile
