[Experience in the sanation of a pedigreed poultry farm pullorum disease]

A trial was carried out for the sanitation of three elite flocks of a total of 3578 chickens on a pedigree poultry farm applying the method of eliminating the infected birds. These were detected with the use of the whole-serum agglutination reaction (after Huddleson) and the tube agglutination reaction (after Wright). No means whatever were used to control the disease. Routine microbiologic methods were employed, however, to examine the eggs, embryos, and chicks obtained from these flocks. Thorough disinfection on the premises including all equipment as well as deratization were conducted after each investigation and elimination of infected birds.
