Chronic carriage and familial transmission of typhoid in western Sydney.

چکیده
Typhoid is a systemic bacterial disease caused by Salmonella enterica subspecies enterica serovar Typhi (commonly S. Typhi).1 It is usually contracted by ingestion of food or water contaminated by faecal or urinary carriers excreting S. Typhi.2 Typhoid continues to contribute to the global burden of disease, particularly in countries with low and middle gross national income.1 Locally acquired cases of typhoid in Australia are uncommon, with most cases being associated with international travel.3

Chronic Salmonella carriers are typically asymptomatic, intermittently shedding bacteria in the feces, and contributing to disease transmission. Detecting chronic carriers is of public health relevance in areas where enteric fever is endemic, ...

Such carriers are thought to be reservoirs for further spread of the disease. Gallbladder carriage has been demonstrated to be mediated by biofilm formation on gallstones and by intracellular persistence in the gallbladder epithelium of mice. In addition, bot...
