Background: Salmonella typhimurium is a rod-shaped bacteria with a Gram-negative
genus, belonging to the Enterobacteriaceae family of microbes, which invades the intestinal lumen
of Human. Salmonella typhimurium is a root source, accounting for gastroenteritis in humans as
well as in other mammals. Gastroenteritisis associated with Salmonella Typhimurium interacts
with the contaminated food and water and spreads to nearby people in the area. Small intestine is
attacked by Salmonella, which then enter into the bloodstream momentarily, and are responsible
for millions of mortalities and morbidities around the globe. Salmonella typhimurium toxins cause
gastrointestiritis due to inflammation in the stomach and intestine in infants and young children. It
accounts for millions of deaths with a higher incidence rate in developing countries.
Methods: In the current research, subtractive proteome mining has been done to recognize putative
drug targets. The proteome was analyzed through blast in order to exclude homologous proteins.
Bacterial essential proteins were predicted and the participation of the essential genes in the
metabolic pathways has been analyzed.
Results: 36 essential genes and 15 unique pathways have been identified as potential drug targets
among the total of 1934 proteins. The location of proteins is determined as an outer membrane. 3
proteins out of 36 essential proteins are recognized as putative drug targets.
Conclusion: In the future, virtual screening for the evaluation of novel clinical compounds for the
identified proteins will be effective and valuable for Salmonella Typhimurium infection in Homo
