Scanning electron micrograph (SEM) of four highly magnified rod-shaped, motile, Gram-negative Salmonella infantis bacteria


Though Salmonella infantis is indeed one of the Salmonella spp. pathogens responsible for causing Salmonellosis, half of all salmonellosis cases are caused by 2 serotypes: S. enteritidis (SE), and S. typhimurium (ST), which is responsible for the disease ”Typhoid fever”. Clinical features of Salmonellosis include fever, abdominal cramps, and diarrhea, which is sometimes bloody. Occasionally these bacteria can establish a localized infection such as septic arthritis, or can even progress to sepsis, which occurs due to the systemic spread of these pathogens.
