Some salmonellae begin to disseminate hematogenously to a variety of ectopic sites, including the bones, lungs, liver, brain where they cause osteomyelitis, pyelonephritis, empyema, hepatic necrosis, meningitis. Bacteria that do not reinfect the host are shed in the stool and sobecomeavailable to infect others. As S.typhi shares O and H antigens with other Salmonella serotypes and has cross-reacting epitopes with other Enterobacteriaceae, false-positive Widal test results may occur in other clinical conditions such as malaria, typhus fever, bacteremia caused by other organisms as well.
