By: Susana Vergil-Alvarado Salmonella Typhi By: Susana Vergil-Alvarado

Shape and Arrangement Shape: Rod Flagellated and motile Non-spore forming

Classification Kingdom: Eubacteria Phylum: Proteobacteria Class: Gamma Proteobacteria Order: Enterobacteriales Family: Enterobacteriaceae Genus: Salmonella Species: Salmonella Typhi

Unique Structural Features: Mode of nutrition: Salmonella Typhi gets its food from other living organisms. Effect of Oxygen: Facultative anaerobic

Historical Significance It is a multi-organ pathogen that inhabits the lymphatic tissues of the small intestine, liver, spleen and blood stream of infected humans. It is a Heterotrophic bacteria

Gram Stain Characteristics Salmonella Typhi is Gram Negative (light red or pink color)

Health-Related Issues: Typhoid Fever: Caused by the ingestion of the bacteria in contaminated food or water Treatment: Antibiotics that kill the Salmonella bacteria. Modes of transmission: Oral transmission via food or beverages handled by an individual who chronically sheds through urine. Hand-to-mouth transmission after using a contaminated toilet and neglecting hand hygiene Oral transmission via sewage-contaminated water or shellfish
