Fowl Typhoid and Pullorum Disease
ثبت نشده
چکیده
Pullorum disease of chickens is a bacterial infection caused by Salmonella enterica subspecies enterica serovar Gallinarum biovar Pullorum (Salmonella Pullorum)1. At this time the serovar is referred to as Gallinarum in some parts of the world and Pullorum in others; in this chapter the serovar will be referred to as Gallinarum or Pullorum according to the biovar under discussion as this is more meaningful from a clinical and epidemiological perspective.

Fowl typhoid (FT) and pullorum disease (PD) are septicaemic diseases, primarily of chickens and turkeys, caused by Gram negative bacteria, Salmonella Gallinarum and S. Pullorum, respectively. Clinical signs in chicks and poults include anorexia, diarrhoea, dehydration, weakness and high mortality. In mature fowl, FT and PD are manifested by decreased egg production, fertility, hatchability and ...

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...

متن کاملThe genome of Salmonella enterica serovar gallinarum: distinct insertions/deletions and rare rearrangements.
Salmonella enterica serovar Gallinarum is a fowl-adapted pathogen, causing typhoid fever in chickens. It has the same antigenic formula (1,9,12:--:--) as S. enterica serovar Pullorum, which is also adapted to fowl but causes pullorum disease (diarrhea). The close relatedness but distinct pathogeneses make this pair of fowl pathogens good models for studies of bacterial genomic evolution and the...
