For example, recent FDA studies link Guatemalan cantaloupes with Salmonella Panama. In speaking of other salmonella serotypes, enteritis Salmonella and Salmonella typhoid/paratyphoid Salmonella,the latter—because of a special virulence factor an a capsule protein (virulence antigen)—can cause serious illness, such as Salmonella enterica subsp. enterica serovar Typhi. Salmonella typhi is adapted to humans and does not occur in other animals.
Salmonella species are facultative intracellular pathogens that enter cells via macropinosomes.
