Is Salmonella typhimurium Gram positive or negative?
Salmonella enterica serotype typhi is a gram-negative bacterium that is responsible for typhoid fever and has been a burden on developing nations for generations.
Where is salmonella hosted?
Salmonella species lead predominantly host-associated lifestyles, but the bacteria were found to be able to persist in a bathroom setting for weeks following contamination, and are frequently isolated from water sources, which act as bacterial reservoirs and may help to facilitate transmission between hosts.
How does Salmonella infect the host?
Salmonella prefers to replicate and infect host cells intracellularly. Once Salmonella is ingested, it invades the epithelial cells of the intestine, as well as nearby phagocytic immune cells.
What are the hosts of Salmonella typhi?
S. Typhi is a highly host-adapted pathogen; humans comprise the only natural host and reservoir of this infection.
Is Salmonella heterotrophic or autotrophic?
S. enteritidis is a heterotrophic organism which means that it does not produce its own food. It gains nutrients by feeding inside of the host. Infants and elderly are at the highest risk for being affected by Salmonella as their immune systems are generally the weakest.
Which food is commonly linked with Nontyphoidal salmonella?
Nontyphoidal Salmonella: Nontyphoidal Salmonella is typically caused by eating contaminated food of animal origin, such as eggs, meat, poultry, or milk.
What toxins does Salmonella produce?
