[Enterotoxigenicity and neuraminidase activity of bacteria of the genus Citrobacter]

The data obtained in the study of Citrobacter strains isolated from patients with diarrheal diseases and from healthy persons are presented: enterotoxigenicity was studied in 68 strains, while neuraminidase activity in 41 strains. Among the strains of these groups 9 strains with active enterotoxin and 2 strains producing active neuraminidase were detected. The criteria for subdividing Citrobacter strains according to the activity of their thermolabile enterotoxin are proposed.
