Some Salmonella strains produce capsules, and capsule antigens are unique to some Typhi
serovars. What role may a capsule play in survival of the organism in a host or in a food-
processing facility?
Serovar Enteriditis has been difficult to control in poultry. What unique characteristic(s) of this
pathogen contributes to the control problem?
Individuals on antibiotic therapy are more prone to infection with Salmonella. Why?
How might the ATR contribute to bacterial survival in food and subsequently in the host?
The typing scheme for Salmonella is based on two antigens. What is meant by the nomenclature
6,7:r:1,5? (simple identification of components)
Salmonella outbreaks have been linked to the consumption of fresh ripe tomatoes. What is the
rationale for this phenomenon?
Non-typhoid strains of Salmonella can cause systemic disease. How does this happen? Which
groups of individuals are most susceptible to this type of infection?
Where are virulence genes located? Why are these genes often used for molecular identification
versus biochemical identification?
Why is typhoid disease rarer than salmonellosis?
Despite global morbidity, mortality due to NTS (Non-typhoid Salmonella) infection is primarily
restricted to the developing world. What do you think is responsible for this phenomenon?.
