A long-term carrier of cholera: cholera Dolores.

Abstract

The first known long-term carrier of cholera, found in the Philippines, is described. The carrier, Dolores M., who had suffered from El Tor cholera in August 1962, continued intermittently to excrete vibrios of the same characteristics as the original isolates until the date of reporting (1966). Duodenal intubation proved that the vibrios are lodged in her biliary tract. Her serum antibody titre continued to remain high in the absence of vaccination against cholera.
