[Further observations on healthy carriers of Salmonellae in the province of Ferrara (1976-1977),(author's transl)].

366 Salmonella strains (2.03%), belonging to 40 different serotypes, were isolated by Authors in 1976 from feces of healthy subjects, in the province of Ferrara; 262 strains (1.45%), belonging to 34 serotypes, were isolated in 1977. The Authors found no significant difference between isolations carried out in both sexes; highest frequencies of isolation were recorded in August, September and October. We have also reported the serotypes more frequently isolated by various Authors from sick and healthy men feces, from animal feces, from sewage and from surface waters.
