Abstract

Salmonella typhi is a negative basil Gram bacterium that causes typhoid fever. Flagel of S. typhi contain proteins, as locomotor and it can help bacteria to attach on host cells. Haemagglutinin protein is protein that can agglutinate erythrocytes. The goal of this research is to analize S. typhi flagellin proteins haemagglutination activity Based on ABO blood group. Flagellin proteins isolation method of modified Alexan method (2009) and haemagglutination test method of Finkeltein and Hanne method (1982). Haemagglutination result of ABO blood type show that SLT-1 S. typhi flagellin proteins can’t agglutinate human erythrocytes A, B, and O, but it can agglutinate human erythrocytes until 8 times dilution of AB blood type from 50 μg/μl concentration in 50 μl. BA 07.4 S. typhi flagellin proteins can agglutinate human erythrocytes of A blood type until 16 times dilution, 8 times dilution of AB blood type, 4 times dilution of O blood type, and it can’t agglutinate human erythrocytes B blood type.Keywords: Salmonella typhi, Flagellin Proteins, Haemagglutination, Erythrocytes of ABO System.

Abstract

The purpose of this study is to molecularly characterize 7 strains of flagellin proteins of Salmonella typhi isolates taken from Central Java (5 strains from Semarang, 1 strain from Salatiga, 1 strain from Magelang) and 2 isolate strains from Yogyakarta (1 strain from Doctor Sarjito Hospital, and 1 strain from Bethesda Hospital). Flagellin gene (fliC) amplification is conducted using PCR (primer LPW 1856 and LPW 1857). Flagellin proteins resulted from Alexan method (2009) is then modified while flagellin protein profiles are obtained with SDS-PAGE method. The results show that the size of flagellin gene (fliC) of S. typhi Isolates from Salatiga and the 8 other strains is respectively 1262bp and 1500bp. Flagellin proteins which are composed of 2-6 protein sub-units consist of 1-2 major proteins and 1-4 minor proteins with the sizes of 16-116 kDa.Keywords: Salmonella typhi, flagellin, Molecular Characterizations
