Despite the fact that gallstones are associated with chronic carriage of Salmonella, patients without gallstones have also been reported as chronic carriers (18, 19). Salmonella Typhi asymptomatic chronic carriage represents a challenge for the diagnosis and prevention of typhoid fever in endemic areas. Treatment of chronic urinary salmonella carriers with trimethoprim-sulphamethoxazole. Eur J Clin Microbiol. They are responsible for silent introduction of the bacteria into the food chain and the environment. Asymptomatic carriers have furthered the spread of many infectious diseases.

Predicting toxins found in toxin-antitoxin systems with a role in host-induced Burkholderia pseudomallei persistence. The most famous example of a human chronic carrier of salmonella is "Typhoid Mary." Salmonella not only causes acute infections, but can also cause patients to become chronic “asymptomatic” carriers. NLM Systematic review with meta-analysis: the relationship between chronic Salmonella typhi carrier status and gall-bladder cancer. 1. Aliment Pharmacol Ther. 17-19. Indian J Gastroenterol.

This type is usually transmitted through direct contact with a fecal matter of an infected person. Biliary Calculi in Chronic Salmonella Carriers and Healthy Controls: A Controlled Study. Salmonella has been veriﬁed as a pathogenic factor that contributes to chronic inﬂammation and carcinogenesis. Chronic Salmonella serovar Typhi carriers have an increased risk of carcinoma of the gallbladder (86, 87). . These individuals excrete large numbers of the bacteria in their feces and transmit the pathogen by contaminating water or food sources.

Differential Diagnosis: Not applicable. Humans can also carry a certain type of salmonella infection known as typhoidal salmonella. Chronic carrier state is defined as Salmonella in the stool or urine for greater than 1 year. NIH Microbiologic culture of blood or bone marrow remains the mainstay of laboratory diagnosis. In this review, ... (1–6%) of typhoid patients become chronic carriers of S. Typhi [6,7].
