ShET-1 is located on chromosomes encoding set1 (A and B subunit) genes, is almost exclusively found in several S. flexneri serotype 2 isolates and is rarely found in other serotypes [32]. Based on the results of the biochemical reaction assays, we observed that all 54 S. flexneri isolates possessed 4 typical Shigella biochemical characteristics (Table1). 2009;9:278. Our results suggested that the predominant ST was ST 100, which has previously been found in human S. flexneri isolates [37, 38]. All four types of Shigella can cause shigellosis, but S. flexneri is the most common bacterial preparation used for shigellosis [23]. .

Induction of apoptosis is dependent on IpaB binding to the cysteine protease caspase-1 (Casp-1). Research performed over the last 25 years revealed that a type III secretion system (T3SS) encoded on a large plasmid is a key virulence factor of Shigella flexneri. The ipaH gene is located only on the inv plasmid, and compared with the chromosome gene, the stability of the IPAH plasmid for storage/subculturing is poor [6,7,8].

In addition to this series of pathogenic events, only S dysenteriae type 1 has the ability to elaborate the potent Shiga toxin that inhibits protein synthesis in eukaryotic cells and that may lead to extraintestinal complications, including hemolytic-uremic syndrome and death. Trans R Soc Trop Med Hyg. [7] J. Sutherland, in Understanding Pathogen Behaviour, 2005 Shigella. Specific Virulence Factors VirA belongs to the GTPase-activating protein family, which is involved in the cleavage of a single membrane into vacuoles. Several useful genotyping tools with higher discriminatory power than traditional tests, including MLST [33], PFGE [34] and MLVA [35], have recently been applied to explore and analyze the characteristics of Shigella isolates. Therefore, it should be noted that the ial gene is involved in the invasion of intestinal cells and that the higher positivity rate of this gene in S. flexneri might indicate stronger aggressiveness.
