Shiga toxins belonging to a family of structurally and functionally related protein toxins serve as the key virulence factors for pathogenecity of the virulent enteric bacterial strains namely Shigella dysenteriae serotype 1 including Shiga toxin-producing Escherichia coli (STEC). S. dysenteriae type 1 isolates remain major public health concerns due to their widespread outbreaks and the severity of extra-intestinal diseases, including acute renal failure and also affects the central nervous system. Despite practicing improved hygienic conditions and regulating food and drinking water safety, the enteric pathogens are imposing a major threat in the well being of the human society. Shiga toxin on entry into host cells’ endoplasmic reticulum (ER) activates the stress response in ER and inhibits protein synthesis by catalytic inactivation of eukaryotic ribosomes. In many cell types shiga toxins trigger apoptosis. Recent studies have shown that shiga toxins induce autophagy which activates different signaling pathways in toxin-sensitive and toxin-resistant human cells. In this review the molecular basis of Shiga toxins’ effect on host cell leading to manifestation of the infection in affected individuals are discussed with an emphasis on recent findings.

Plants contain a broad spectrum of small molecules with potential antimicrobial properties. Here, we review the antimicrobial activities of plant extracts against enterotoxic bacteria encoding AB5 toxins, including Vibrio cholerae, Shigella dysenteriae and enterotoxic Escherichia coli strains. Several plant extracts have strong antimicrobial effects and the potential to boost Oral Rehydration Therapy, which is the first line of treatment for acute diarrhea.

Probiotics have antibacterial effects against pathogenic bacteria in the gut while maintaining the balance of intestinal flora such as Lactobacillus. This study aimed to evaluate the antimicrobial activity of four Lactobacillus species against intestinal pathogenic. Four different species of Lactobacillus (Lactobacillus bulgaricus (PTCC 1332), Lactobacillus casei (PTCC 1608), Lactobacillus plantarum (PTCC 1058) and Lactobacillus Fermentum (PTCC 1638)) were experimented to investigate the inhibitory activity against 4 bacterial enteric pathogens (Escherichia coli, Staphylococcus aureus, Shigella dysenteriae and Salmonella paratyphi A) which were separately inoculated in MRS medium (de Man, Rogosa and Sharpe medium) for 48 hours at 37 °C and pH 7. Our results showed that enteropathogens growth was stopped in the presence of all Lactobacillus and inhibition zone was between 12 and 32 millimeter. It can be concluded that these four Lactobacillus strains had potential antimicrobial compounds against human enteric pathogens and should be further studied for their human health benefits.
