The Occurrence of Type 10 Paracolon in Turkeys

Abstract
A coliform organism was isolated from 19 outbreaks in turkeys on 17 ranches. Antigenic and cultural studies showed it to be a non-sucrose-fermenting paracolon designated by Edwards as type 10 and having the antigenic formula XVIII: z4 x2 x7. Symptoms and pathology resembled those seen in salmonellosis, with mortality ranging from 5 to 70 per cent. Agglutination tests conducted on survivors of outbreaks indicate that the infection is more easily aborted than is pullorum disease. Preliminary trials indicate that treatment with sulfamerazine was effective.
