Assessment of cArrier stAtus of Salmonella Pullorum And GAllinArum infection in heAlthy flocks

چکیده
Poultry are commonly infected with a wide variety of salmonella serovars and infection is generally subclinical (Wray et al., 1996). Poultry farming is often hampered by reduction in productivity due to infections with large number of bacteria, salmonellosis being the most important causing great economic losses due to mortality and reduction in egg production (Khan et al., 1998). Under the new naming system the Salmonella serovar Gallinarum is divided into biovar Gallinarum and Pullorum, which are identified to cause Fowl typhoid and Pullorum disease respectively. While fowl typhoid is a disease of mature birds, pullorum causes mortality of embryos and chicks. Infection with these pathogens are responsible for considerable economic losses in poultry production. The aim of this study was to determine the serological prevalence of these two biovars in apparently healthy domestic chickens and thereby assess the carrier status.

Salmonella gallinarum with the biotypes gallinarum and pullorum causes two septicaemic diseases in poultry: fowl typhoid (FT) and pullorum disease. The former Salmonella pullorum serovar is not recognised anymore as such. Both biotypes are differentiated by a few biochemical and molecular tests. Mammals may be infected without showing any illness. In contrast to zoonotic salmonella serovars, Sa...
