Age of cases infected with ETEC isolates expressing CFA/I, CS5plus CS6, CS6, and CS14

CF typeNo. (%) of children stratified by the following ages:
<1 year (n = 147)1 < 2 yr (n = 134)>2 yr (n = 39)0-5 yr (n = 320)

  • a In children less than 1 year of age, ETEC CS6 was recovered significantly less often than CFA/I (P = 0.0001), CS5 plus CS6 (P = 0.03), other CF types (P = 0.007), and CF undetected (0.0001).

  • b Others include CS1, CS1 plus CS3, CS2 plus CS3, CS3, CS4 plus CS6, CS5, CS7, CS8, CS12, and CS17.

  • c CF was undetected with a panel of 12 monoclonal antibodies to CFA/I, CS1 to CS8, CS12, CS14, and CS17.
